2023 Chevrolet Silverado 1500 Engine Problems

Your engine suddenly stopped working while you were driving on the freeway with no warning signs beforehand. The dealership confirmed this is a known issue affecting the 6.2L engine in your model year. You were able to safely pull to the shoulder, but you're concerned that Chevy may install the same engine and the problem could happen again. The fix will likely involve a complete engine replacement or repair by the dealership.

Your engine shut down while driving at 70 mph and displayed a "Hot Oil Shutting Down" message. The dealer found that the engine had failed completely and needs to be replaced. This happened after your truck was repaired under a recall campaign (25V274000) for engine and cooling system issues. The engine replacement should involve removing the failed engine and installing a new one.

Your 2023 Silverado 1500 has experienced multiple serious issues, including an abnormal engine sound and poor responsiveness while driving. Most critically, the cooling system has failed twice — causing the engine to overheat and triggering a "Reduce Acceleration" warning message — and there's an oil leak between the engine and transmission. Your instrument panel also goes blank intermittently, and the 360-degree camera stopped working (though this was repaired). Fixing these issues will likely require the dealer to replace cooling system components, reseal the engine-transmission connection, and diagnose the electrical problem causing the dashboard blanks.

Your engine started making unusual noises and shutting off unexpectedly, with signs of locking up. This suggests internal engine damage or failure that requires professional diagnosis and likely replacement or major repair of engine components.

While driving at 75 MPH, your engine started running rough and shaking, then lost power and made a loud bang before the engine failed completely. The transmission also showed fault codes during diagnosis. Even though there's a related recall campaign, your vehicle's VIN wasn't included in it. The engine will likely need to be replaced or rebuilt, and the transmission may need inspection or repair.

Your engine is making a loud, rhythmic metallic ticking or tapping noise from the top, which your Chevrolet dealer has confirmed. This noise is caused by manufacturing debris in the hydraulic valve lash adjusters that prevents proper lubrication of the valvetrain. This defect can lead to engine misfires, sudden loss of power while driving, and potential engine seizure — creating a serious safety risk, especially at highway speeds or during passing. The dealer is aware of this issue but has not addressed it with a repair or recall.

Your engine seized while driving at highway speeds on March 7, 2026, causing a sudden loss of power and power steering/braking that nearly caused a multi-vehicle crash. The owner alleges the dealer falsified a safety recall by marking it complete without performing the required oil cap replacement (0W-40), and that the truck may be a salvage vehicle with mismatched VIN numbers that was improperly rebuilt and resold. The engine repair will likely require a complete engine replacement or rebuild, along with investigation into the vehicle's true history and ownership documentation.

Your engine suddenly lost all power while you were driving, with no warning light beforehand. The dealer diagnosed a complete engine failure that requires a full engine replacement. Your truck had about 41,100 miles when this happened. The fix will involve replacing the entire engine.

While driving at 65 MPH, your truck suddenly lost power and displayed warning lights telling you it wouldn't exceed 55 MPH, then later 30 MPH. The dealer diagnosed a faulty DEF tank heater as the cause but couldn't complete the repair because the part is on national back order. The fix will require replacing the DEF (diesel exhaust fluid) tank heater.

After the recall service on your 6.2L engine, your fuel economy dropped by 5 miles per gallon with no changes to your driving habits or fuel type. You've consistently monitored your fuel mileage and noticed this decline started immediately after the recall was performed. The dealer may need to review the recall work and engine tuning to identify whether the service affected fuel efficiency settings.

Your check engine light, stability control light, and ESC light came on at 6,500 miles, along with rough engine running, reduced engine power, and harsh transmission shifts. The dealership diagnosed that your engine lifters and rods need to be replaced. This repair will likely involve removing and disassembling the engine to replace the faulty internal components.

Vehicle had recall for L87 engine performed, resulting in a change to 0W-40 motor oil and a new fill cap. Approximately one week later, the engine failed completely, with evidence of significant bearing wear in the used oil analysis I had performed. The engine has since been replaced under warranty. There was no prior warning to the failure, except for unusual noises during the failure.

Loss of engine propulsion while traveling down a highway towing a #5000 trailer at 65 mph. Less than five miles before the failure the vehicle experienced a momentary downshift of the transmission such as you would experience while climbing a hill or extreme headwind. No warning lights were present at that time or at any time prior to engine shutdown. Upon failure panel indicated "Press Engine Start" and transmission indicated "Park" though we were rolling/coasting at over 60 mph. Realizing that we had lost propulsion I guided the vehicle to the shoulder and stopped. Solid check engine light on at this time. Depressing the "Start" button while stopped would not start or crank over the engine. Boost box would not crank engine, slight noise from starter as if unable to turn engine over. Called tow truck, Seewald's Towing in St. Ignace, MI. Towed to nearest Chevrolet dealer Wheeler Motors Cheboygan, MI.

My 2023 Chevrolet Silverado 1500 has experienced two separate major drivetrain failures — complete transmission and turbo replacements — within two years of purchase, both during peak use months. The second repair kept the vehicle in service for nine months with no ETA provided until escalation. The repeated failures have rendered the vehicle frequently unusable, caused significant business loss, and represent more than normal wear. Documentation of repairs and dates is attached.

My 2023 Silverado 1500 6.2L ZR2 AEV with 17,500 miles went into the shop for the L87 Loss of Propulsion recall, on 20 OCT 2025. The dealership didnt contact me for 2 weeks, so I called. They than told me my truck failed the pico test and needed a new engine. I also asked for my leaf springs to be looked at under tsb for excessive noise. I also asked for my ZR2 to have the new update installed for the radio fix (my speakers crackle when I talk to people on bluetooth). They had my truck from 20 OCT 2026 until 27 JAN 2026 for a total of 99 days straight. No loaner was available. I had to call GM customer service every week for subpar updates from the dealership. Im active duty army so not having my pov to report to work was very stressful. When I got my truck back, it was covered in dirt, oil on the exterior paint and inside the engine bay. The dealership didnt update my truck as requested and didnt touch my leaf springs at all. They said it would take 5-7 weeks to get new ones, but I needed my vehicle back which is anitated on the work order. Thr parts were all delivered 45 days after it sat there and my truck wasn't worked on until day 94 as advised by the service advisor, as the mechanic would get to it after his next vehicle. I asked how is my truck not priority sitting there for 93 days at the time. GM customer service has submitted my vehicle payment reimbursement as I paid 4 payments while having no vehicle or loaner. $44 a day for a rental at my duty station would cost me considerable amount of my own money to cover the rest and would not be a similar vehicle to my truck, as ot would be a small car. JN Chevrolet in Honolulu did not communicate when it failed the test for 14 days, I had to call them, they gave zero updates for 2 months, I had to call GM customer service. I only received 4 calls in total from the dealership when I asked to speak to the manager. (Who never called me back). I got my truck back filthy, other services ignored. 3rd Silverado and last.

CONCERN OVER 6.2 ENGINE FAILING WHILE IN CONGESTED TRAFIC

My husband was driving on Plank rd/rt 219 towards Ebensburg PA when the truck started to buck and he turned off the main road and it shut down. It would not start just said low battery. I had it towed to the garage we use. They just confirmed it is the engine it locked up. I had the inspection for the recall and had the oil changed prior to this happening.

My truck took my truck to Austin and back. Woke up the next day. Started it at approximately 4 o'clock in the afternoon and had engine oil low alert. Got out check the oil in my truck and there was none on the dipstick with the truck off of course. Checked at two other times allowing the dipstick to stay in for three or four minutes. Still no oil on the dipstick. Did not drive truck any further. Truck has the 6.2 L and I had the recall applied to the truck on December 8. The truck has 88% of the oil life remaining according to the truck.

My truck passed the recall PICO test right at 20,000 miles. The dealer put thicker 0w40 oil in. Less than 2,000 miles later, upon hard acceleration from 5-8mph, the engine climbed to 58mph then lost power, shifted itself into Neutral and coasted to the side of road. Truck was towed and told the engine seized up. Changing the oil did not make sense to me as lubrication was always available previously, thickening it does not change the port mill sizes for properly oiling the crank bearings. Now the new engine is revised but I see failures in low milage 2026 models happening.

The contact owns a 2023 Chevrolet Silverado 1500. While driving approximately 45 MPH, the message “Reduce Acceleration – Drive with Care” was displayed. The vehicle was driven to the residence with an abnormal rattling sound coming from the vehicle. The vehicle was taken to a local dealer, but the vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the check engine warning light was illuminated. The vehicle was taken to the dealer, and the failure was associated with a coolant sensor failure; however, it was unknown whether the dealer had repaired the vehicle. The dealer then informed the contact that the vehicle was safe to drive. However, while driving 65-70 MPH, the engine overheated and the vehicle stalled. Several unknown warning lights were illuminated. The contact was able to pull over to the side of the road, and the vehicle was towed to the dealer. The failure was initially related to a coolant sensor, and the dealer advised the contact that the part was ordered; however, upon following up, another technician advised the contact that a digital multivalve was ordered. The contact stated that upon returning to the dealer, the dealer advised the contact to sign the service documents. The contact stated that after insisting on reading the service documents prior to the signature, the dealer provided the documents to the contact; however, the dealer later snatched the documents from the contact while the contact was reading the documents. The contact stated that it was unknown whether the vehicle was serviced. The service manager later informed the contact that the vehicle could not be repaired because the contact and the dealer could not come to an agreement. The contact informed the dealer that the vehicle should be repaired under the warranty. The vehicle was picked up from the dealer unrepaired. The check engine warning light was illuminated. The manufacturer was notified of the dealer's denial by the dealer to repair the vehicle. The manufacturer informed the contact that there would be a follow-up with the dealer. The failure mileage was approximately 34,000.

After have the engine tested it was determined that my vehicle will receive the 0W/40 oil. After that change I have notices a lot of rattling and the engine not behaving like it should.

September 2025; the fuel control module failed at 75 mph in the left lane of I-45 requiring me to pull over on the shoulder in heavy traffic. I eas towed to my dealership 170 miles. At that time the recall test was performed on my 6.2 L L87 engine and passed inspection. The oil was upgraded at that time. Jan. 3, 2026 at 65 mph the engine died, once again on the highway at over 65 mph. Again I struggled to get to the right shoulder in heavy traffic. At the moment of failure, the engine revved from 1500 rpm to 3900 rpm and instantly fell to zero rpm and died. A message on the dash read unable to put in vehicle neutral. Again, I had it towed to my dealership where it's been diagnosed with a seized engine and I'm waiting (three weeks so far) on an engine replacement. I'm told the manufacturer rep has been to the dealership to confirm the failure and approved a complete engine replacement. There was never any advanced warning appearing on the dash. I have thorough maintenance records on this vehicle.

The motor blew with no notice, around 1000 miles after the recall inspection. My safety, along with the others around me was put at risk as I was in the fast lane during rush hour traffic with no motor to aid switching lanes to get to the shoulder. Finally died at one of the busiest intersections in the state, for the last time, as I was attempting to limp to the dealer via multiple restarts. leaving me stranded on the side of the road on a wonderful January day. The vehicle has been inspected by the dealer and slated for an engine replacement. No notice, I let off the gas, and when I went to accelerate again, the motor shut off.

General Motors sent me a letter regarding a safety recall regarding my 6.2L V8 gas engine (ROP L87). Safety recall N252494000. I learned that my truck has the potential to have a complete engine failure. I took my truck to the dealership and all they did was an inspection and changed the oil on it. I'm not a mechanic, but total engine failure is concerning to say the least. I doubt simple change in oil thickness remedies serious recall. I learned there is an open lawsuit regarding this issue. I need Chevy to take this matter more serious, Im driving my family around in a ticking time bomb. I demand more than a band-aid. I want Chevy to replace my engine with a new reliable one.

While driving at 70mph, my vehicle spontaneously shifted into Neutral and therefore dropped power to the transmission. I was unable to shift out of Neutral and therefore had to coast to the shoulder. Upon coming to a complete stop, my truck independently shifted into Park. Again, I was unable to shift out of Park. I turned my truck off, let it sit for a few seconds before unsuccessfully attempting to restart my vehicle. Multiple attempts to restart my vehicle continued to be unsuccessful and the vehicle system would reboot then shut off.

My vehicle was part of the recall N25494000 L87 Engine loss of propulsion. Vehicle went in for recall on Sep-30th 2025, PicoScope Inspection was done and vehicle passed. Oil was changed to 0W 40 with new oil filter. Dec-26/27 of 2025 vehicle started stalling, for no reason but no Engine light. The dealer said there was no problem because there was no engine light, so there was no way to find out what was wrong. January 11th 2026 vehicle lost propulsion 7 times on the freeway, vehicle had a hard time re-starting and started smelling oil burning smell. Vehicle Engine light stayed on, 1/11/2026 vehicle was running a little rough with abnormal tapping noise but made it to the dealer for inspection.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 25V274000 (ENGINE AND ENGINE COOLING), but the failure occurred. The contact was informed by the dealer that the vehicle had passed inspection, and the dealer added a higher viscosity oil, installed 6 oil fill caps, and replaced the oil filter. The contact stated that six months after the vehicle was repaired, there was an abnormal squeaking sound coming from the engine. The contact stopped at a gas station to refuel. Afterwards, the vehicle failed to restart, and there was smoke coming from under the hood. The contact stated that the engine had seized. The contact was at the gas station when the failure occurred. The vehicle was towed to a dealer; however, no cause for the engine failure was found. The contact was informed that the sound was coming from one of the drive belts. The vehicle was not repaired. The vehicle was then towed to another dealer, where it was diagnosed and determined that the abnormal sound was coming from loose bearings in the engine. The contact was informed that the engine needed to be replaced. The long block in the engine and the radiator were replaced on January 1st. The contact stated that a week after the vehicle was repaired, the vehicle failed to start. After several attempts, the vehicle restarted. The vehicle was taken back to the dealer. However, no cause for the failure was found. The dealer recharged the battery. The contact stated that shortly afterwards, the vehicle failed to start. The vehicle was taken back to the dealer, where it was diagnosed and determined that the starter had failed. The contact requested that the dealer check the ground strap, but the dealer refused. The vehicle remained at the dealer unrepaired. The contact stated that the dealer would notify the manufacturer of the failure. The approximate failure mileage was 44,469.

While driving at highway speeds, in traffic, all dash lights lit up and the engine shut off. The truck began decelerating on its own, I couldn’t brake and could barely steer. Luckily I was going fast enough that I managed to coast about a hundred feet to get partly out of traffic. The truck would never start again and I had to wait for 7 hours for GM roadside assistance to tow me to a Chevy dealer that was 4.6 miles away. 23 hours later the dealer called me and told me the starter caused the problem, in which I told them made no sense. 30 mins later they called and said the motor failed due to recall N252494003 for the L87 engine. My truck had passed the recall inspection for this recall on Sep 24th, 2025 and received the new oil that was supposed to prevent this failure. I had also just had the oil changed again around Nov 13th because the FCW module needed a firmware update and was not functioning. The truck had given NO warning or issues previous to Dec 3rd.

Please see attachment:

Driving down the road and the engine turns off with no warning lights, noise, or any indication of an issue. I was luckily able to use momentum and move to the side of the road. The Chevy dealer has inspected the engine and concluded that the engine is blown.

I am filing a complaint regarding a potential recurring safety defect related to Recall NHTSA 25V274 (GM N252494001). On July 29, 2025, my vehicle stalled while driving on the highway and was towed to Quality Chevrolet. The dealer diagnosed a failed starter and battery fuse link. During this visit, I authorized inspection for Recall 25V274, concerning possible crankshaft or connecting rod failure. I was told my vehicle was not affected but the dealer performed the recall remedy by changing the oil to 0W-40. On October 5, 2025, the vehicle developed a loud knocking noise from the engine. Quality Chevrolet diagnosed a connecting rod failure, the same issue identified in the recall. On October 10, 2025, I was advised that GM approved a full engine replacement due to internal damage. However, I was also told the new engine will use lower viscosity 0W-20 oil, contradicting the prior remedy intended to prevent this failure. This suggests the original recall fix was only a temporary measure, and the defect remains unresolved. I request that NHTSA investigate whether the current recall remedy adequately corrects this safety issue and whether GM’s use of 0W-20 oil could allow repeat failures. Additionally, I request assistance or reimbursement for vehicle payments, as my vehicle has been undrivable for an extended period due to a manufacturer defect. Thank you for your time and attention. I can provide all service records and diagnostic reports upon request.

See attached document for complaint.

The contact owns a 2023 Chevrolet Silverado 1500. The vehicle was recently repaired under NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The contact understood that the option was to use a higher viscosity oil, replace the oil fill cap, and oil filter replacement. The contact stated that the remedy was insufficient to resolve a possible failure with the engine. The contact was hearing abnormal ticking sounds coming from the engine after starting the vehicle in the morning since the recall repair. The contact stated that once the engine had warmed up, the ticking sound ceased. There was no warning light illuminated. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline for assistance. The contact had not experienced a failure with the engine.

We bought 2 of the same exact trucks last year. They each had no miles on them. My business partner was coming home from vacation and stated hearing ticking. We took it to our mechanic and he said it’s a blown motor. Prior to leaving for vacation, an oil change was done on the truck. When the mechanic said the motor is blown he also said it’s down 3 quarts of oil. All scheduled maintenance was done on the truck routinely. We took the truck back to the shop that did the oil change and they had recorded the service, there was no doubt the oil was changed the prior week but it was now black and down three quarts.

I have a 2023 Chevy Silverado 1500 3.0L Duramax Trail Boss. Temperature gauge keeps flocculating, engine fan kicks on at 100% and shuts off the AC. Warning on dash engine temperature to high AC shutting off and engine over heat. Took it to the dealership for the truck is still under warranty. They diagnosed it as a faulty coolant control valve. Was told it was safe to drive by the technician but I question that. Dealership ordered the part four weeks ago and it still has not come in. When I inquired about the delay, I found out it is on back order and the availability of the part long wait time. Further research found that this is a systemic issue owners are having with this specific engine since 2020. Yet GM has not done a recall nor is there supply stockage of this part, seeing how this part commonly fails.

The contact owns a 2023 Chevrolet Silverado 1500. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The contact stated that while driving 65 MPH uphill, the check engine warning light illuminated. The contact pulled over to the side of the road and turned off the vehicle. The contact was able to restart the vehicle after waiting for several minutes. Additionally, the contact stated that vehicle was idling rough while driving. The contact stated that the rough idling persisted. The vehicle was taken to the dealer but was not diagnosed or repaired because the recall repair part was not available. The contact scanned the vehicle with a diagnostic code reader and retrieved DTC: P0016, which indicated that the powertrain control module (PCM) had detected that the crankshaft and camshaft were not synchronized. The vehicle was not repaired. The manufacturer was not made aware of the failure. The contact had safety concerns while driving the vehicle. The failure mileage was approximately 49,500.

The dealer was notified of the failure and an appointment was scheduled to have the vehicle serviced. The contact stated that while in a store parking lot, the vehicle failed to start after several attempts. Due to the failure, the vehicle was towed to the dealer where the mechanic discovered that a fuse connector was loose, causing the failure to start. The contact was also informed that the dealer failed to replace several screws and bolts back in place once the engine was replaced. The vehicle occasionally surged forward or hesitated while depressing the accelerator pedal, causing the contact to lose control of the vehicle while driving at various speeds. The manufacturer was made aware of the issues and the contact was informed that a refurbished engine was placed inside the vehicle and not a new engine as the dealer had stated. The vehicle remained with dealer due to safety concerns. The vehicle was not repaired. The failure mileage was approximately 26,000.

The vehicle began making a loud fan noise in the engine after the summer began (06/2025) and the temperature gauge was elevated but not by a concerning amount. After an oil change (06/21/25) we were told that it was normal because of the weather. A week after the check engine light was coming on intermediately (began 06/28/2025) depending on the day and the temperature outside (we are currently in the middle of a heat wave). The vehicle was taken to the dealership (07/02/2025) where they determined that the coolant flow was too low and found that the engine coolant pump is faulty and needs to be replaced. f the coolant is low in a Chevy Silverado and the engine overheats, it can lead to significant and potentially expensive engine such as a blown head gasket, cracked engine block, or even a complete engine failure or fire.

I been to the Chevy dealership a few times for the 6.2 L recall that I have and I keep getting turned away

So I experienced a P1098 code in my 2023 Chevy Silverado with a 3.0 liter Duramax. When you get this code the truck will go into “limp” mode with reduce (nonexistent) acceleration and only go to about 60 miles per hour (63) I think. This could become a large safety issue if someone was to experience this going down the highway. It is also a VERY common problem doing internet searches. Seems that GM knows this is an issue but does nothing about it. In fact they even tried to remove the part from warranty because it was happening so often. Seems like this is something the government should look into and see what the true cause of the issue is. On the other hand some of the reliability of these engines is caused by the government implementing many restrictions on the manufacture to meet certain requirements. I am frustrated this happened along with probably with thousands of other owners. Thanks!

I own a 2023 Chevrolet Silverado 1500 ZR2 equipped with the 6.2L V8 L87 engine. My vehicle is included in Recall Number 25V274 / N252494000, which addresses manufacturing defects in the connecting rods and/or crankshaft that can cause engine failure. My recall status currently shows: "Recall Incomplete, remedy not yet available." However, GM and NHTSA have already stated the remedy: a VIN-specific engine inspection, followed by either a replacement or an oil system update and extended warranty. I contacted my dealership, Lochmandy Chevrolet in Elkhart, Indiana [XXX] ), and was told on June 1, 2025, that they could not inspect my truck due to lack of tools or VIN clearance from GM. I was given no estimated timeline for when I can get my vehicle serviced. My concern is that I’m driving a known defective vehicle with a potential for sudden power loss or engine seizure—a serious safety hazard. My truck currently has 19,500 miles, and I’m worried about continued use without an inspection or remedy. I’m requesting that NHTSA follow up on GM’s delays in remedy deployment, ensure dealerships are equipped for inspections, and provide vehicle owners like me with a firm timeline for repairs. Please open a case and provide a reference number. I can be reached at [XXX] for updates. I am documenting all interactions with GM and my dealership for safety and legal purposes.

I take my truck in for regular service at my local Chevy dealership. When I found out about the recall on my engine back in April I immediately took my truck in. Was advised that they would address the issue. They did a regular maintenance and told me that they just used higher viscosity oil. I will be taking my truck in for the 3rd maintenance tomorrow 6/13/25. My vehicle status still shows that the recall needs to be addressed. I feel that I should park my truck due to the information provided on the recall of losing propulsion at any given time without notice. I also want to note that there is a noise coming from my engine that shouldn’t be there.

On 4-25-2025 while driving the car shutoff twice losing power on both occasions. The first time I was able to start the truck; however, the second time it happened I lost all power and drifted to a stop. Vehicle info said to put the car in neutral and press the start button. Car failed to start while drifting and when I was able to get the truck to a complete stop, the truck could never start thus requiring it to be towed to the dealership. Truck has a little over 22000 miles. Check engine light came on after the second incident.

I have had an intermittent, aggressive engine knock and rough idle since i bought the truck. I'm assuming it has to do with the collapsing lifter issue from the fuel management system. when I bring it to the dealership (paradise chevrolet ventura) , they tell me that they cannot replicate the issue and that if there is no check engine light on the dash, there is nothing they can do. I am concerned for my families safety and my truck becoming an issue after my warranty runs out. my chief complaint has been documented by the dealership multiple times and I have video of me replicating the issue.

On [XXX] around [XXX], I was driving my Silverado down [XXX] near the Cottonwood Mall in Albuquerque, NM. Without warning, the engine died in the center lane of this busy highway. I turned on the emergency flashers, then while trying to call for emergency help on my phone, I stood behind the truck, waving traffic to the side lanes in an effort to prevent being rear ended. After about 10 minutes, luckily, an emergency fire department truck spotted my distress and doubled back, parked behind me and engaged his emergency lights. A good Samaritan stopped an attempted to toe strap me to the shoulder of the road. However, the poor design of this truck didn't allow me to put the transmission in neutral unless the vehicle is running. So, after about an hour, the tow truck driver was able to drag the Silverado on the back of his flatbed. After my truck was at the dealer for a week, they were able to determine that the engine main bearings seized and spun a couple of rod bearings. This is a well maintained vehicle, with the oil changes done on time and documented at the dealership. My Silverado has a 6.2 liter V 8.engine with only 21,532 miles on it.

While driving my 2023 Chevrolet Silverado ZR2 with the 6.2L engine (approx. 22,000 miles) on a busy interstate in another state, the vehicle suddenly lost power and shifted into neutral without warning. I was towing a 5,000-pound camper and had my wife and three children in the truck. We were traveling on a slight incline when the truck unexpectedly disengaged. There were no warning lights, no messages, and no sounds indicating engine failure—just a sudden loss of drive. All displays remained illuminated, but I had no power to the wheels. By the grace of God, I was able to maneuver to the median before the truck and camper came to a complete stop. It was a terrifying and dangerous situation that could have resulted in a major accident given the speed of traffic, the weight of the trailer, and the total lack of warning. The truck was towed to a Chevrolet dealer across the state line. After running diagnostics, I was told the engine had failed and would need to be replaced under warranty. However, I have yet to receive a clear explanation of what exactly failed internally. I was informed that a replacement engine is back-ordered by several months, leaving me without a vehicle and unsure when it will be repaired. The incident has not yet been investigated by the manufacturer, insurance, or law enforcement. This experience was frightening not just because of the mechanical failure, but because it happened with zero indication. I hope others don’t have to go through something like this. I understand thousands of these trucks may never see a failure like this—but for us, it happened suddenly, with our entire family on board, and it nearly ended in disaster.

While traveling in a funeral possession noticed an engine stall with a blast of smoke coming from rear exhaust.

Engine died when I was traveling at highway speed. Not warning lights no check engine lights. Was able to stear to the shoulder but vehicle woulnd't start or go into nuetral. Thankfully on a rural road so was able to get out of danger. Had this happened in a busy environment may not have been so forturnate. Dealer determined that 2 of the connecting rods bent and caused catostrophic engine damage. Since this happened I have read about 100's of other 6.2L gasoline engines having similar issues. This isn't a random occurance and Chevrolet has writted technical memos explaining the issue for thier dealers.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving 75 MPH, the vehicle lost motive power with the check engine warning light illuminated.

Main bearing failure at 41,000 Miles. No prior warning to issue. Truck is currently at the Chevrolet dealer determining if repair or full engine replacement is needed and parts availability. Check engine light came on when the engine started to make noise.

On 3/1/2025, while driving, my vehicle became unresponsive and inoperable . My vehicle stopped at the intersection in a turn lane. The vehicle engine turned off and a check engine light turned on in the dashboard. There were no sounds or indicators prior to the event. All of the controls became inoperable and unresponsive. When I tried to restart the vehicle it would not turn over. I was unable to shift the vehicle out of park. The dash board showed the message “Conditions Not Correct for Shift”. I tried several different corrective actions and referred to the owners manual but I was unable to do anything. The owners manual didn’t specify how to shift the vehicle when it is not running. I had to call a tow truck because we were in the intersection and it presented a concern for safety for ourselves and others the tow truck tried resetting the vehicle, jumping it, and looked for the manual shift override but were unsuccessful. They pulled my truck onto the tow truck and took it to the dealership where I purchased the vehicle. When we arrived at the dealership the tow truck driver consulted with the dealership personnel and were still unable to determine any cause or how to manually shift the vehicle into neutral. My truck has the 6.2L V8 L87 gasoline engine with only 15466 miles. The dealer confirmed engine failure and is in the process of ordering a new engine. There is no known ETA for the engine because it has become a national issue. I have also read multiple encounters of other owners have multiple engines fail and replaced.

I was driving on the highway at about 65 mph, when all of the sudden the truck shut off. There was construction in that part of the highway and there was no shoulder for me to drive off to so I kept driving until the truck completely stopped on the highway. I had to jump off the truck from the passenger side with my wife and toddler and jump the median and stood there in the cold for a few hours while a tow truck came to move the truck out of the highway. We did not fell save staying in the car because there was a lot of traffic and we were afraid to get rear ended. I got the truck towed to my house which cost me $600, the next day i called the dealership to come pick it up. They took it and found the engine was completely damaged. They replaced the engine, but with the same engine model that has the defective engine that NHTSA is currently investigating on these engines. So i no longer feel safe nor can i rely on this truck to run my business.

Traveling at ~40mph when some knocking could be heard. Pedal manipulation was intermittent. No warnings on the dash. Luckily, I was able to use momentum to get the truck off of the main road and onto a side street. Knocking was heard even louder now - pedal manipulation was now even more intermittent. An error message popped up on the display "Conditions not correct to shift", with no other lights coming on. Truck has now coasted to a stop and the check engine light came on. Cannot put the truck into any other gear. I was lucky enough to not be traveling at a higher rate of speed, but I can see this being a huge safety concern. The truck was towed to a local dealer where i was told that the truck has experienced "Spontaneous Engine Disassembly". However, my service record only states "Check Engine Light On". The attached information is the only thing that I have of the incident and how it's being reported.

February 9 2024 I was driving down the highway at 65 mph and went to switch lanes and realized engine was no longer running. I pulled over and got a tow to the dealership I purchased it from . Truck only had 5000 miles on it and they told me the engine locked up and needed replacement. They performed an engine replacement. It was not completed until April 6, 2024. Two months to get repaired. Today I was driving down the hightway and again engine blew. I heard a spun bearing noise from engine compartment area. Pulled over and engine shut itslef off . Had it towed back in to find out I am on a line of a bunch of 6.2 engines needing replaicing. Very disappointed in Chevy.

On [XXX] I was driving @ 55 MPH. The engine made a loud noise, and completely lost all power and controls. Truck went into natural, all dashboard and screens went black. One I was able to come to a stop the vehicle put itself in park. Truck was towed to Jim Butler in Fenton, MO. I was told by the shop that the 6.2L engine in my truck had a catastrophic failure and needed a new engine. The complete and sudden loss of power and controls put myself and others in danger. No lights or warming of the failure about to happen. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

coolant control valve The check engine light came on when I started the truck and on-star ran the diagnostic and said it is code P1098. After drive 20 miles a popup on the dash stated, "slow down and drive safe". I was on a 60-mph road driving 55-mph and the truck started slowing itself down. Took it to one dealer and they said the part was on back order and didn't say anything else

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving 70 MPH during inclement weather, the transmission unexpectedly downshifted hard, jerking the vehicle, and while slowing down the contact observed a squeaking sound coming from the front of the vehicle. The contact stated that while depressing the accelerator pedal the vehicle failed to accelerate as intended. The check engine warning light was illuminated. The vehicle was steered off the highway and turned off. The vehicle was not able to be restarted. The vehicle was towed to a dealer where it was diagnosed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 34,000.

The starter did not disengage and caused engine failure. Loud screeching occurred while driving. Pull off road once noise was heard and truck needed to be hauled back to dealership.

Vehicle started making an odd noise and was immediately taken to the dealer. Engine light did come on after the noise started. Dealer confirmed that there was an issue with the camshaft/lifters and that they have had to perform this repairs to 8 other trucks with the same 6.2L engine. (Original repair bill is attached). Dealer performs the repairs, takes the truck for a test drive and within a few miles the engine completely seizes up stranding the truck in the middle of the road. They believe it was a separate issue that caused the engine to seize up and now after 12k of repairs I will also need to purchase a completely new engine. Currently waiting on the price and availability of a new engine but was told I may have to wait a long time since this is such a common issue there aren’t many available. Would be more than happy to share additional Info as it becomes available.

Engine failure while driving without warning (lights)which caused catastrophic damage to Engine and needed to be replaced

Catastrophic engine failure , heard a ticking called dealer where i purchased truck new , was told not to drive it . No warning..

The motor of our vehicle failed while driving on the interstate. The vehicle is at a dealership for repairs and should be available for inspection. With little to no warning our truck quickly went from 70 MPH to completely shut down. We had to go from the left lane on the interstate to the shoulder. In the process we were very close to a collision. We were also hauling our camper (2023 Forest River R-Pod 153, which has a dry weight of 3,421 lbs and we had no water in our fresh/grey/or black tanks). When we merged into the right lane our truck was going so slowly on the interstate that we were almost hit and honked at before we could get to the shoulder safely. The problem was confirmed by the dealership that is working on it. The motor spun 4 rod bearings and it was a total motor failure. The vehicle was/is still under warranty. The manufacturer, I would assume, has inspected it as we are receiving a full motor replacement. That motor has been and continues to be on back order with no ETA for 2 months now. There were no warnings in how the truck was running. There were no warnings on the dash, warning lights, or any indication that our truck was going to break down.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving 65 MPH, the message that the vehicle was in neutral was displayed. The contact pulled over to the side of the road, turned off, and restarted the vehicle however, the gear shifter failed to respond as needed. The vehicle was towed by AAA to the dealer and the dealer was contacted. The vehicle was diagnosed, and the contact was informed that the engine, the radiator, and the oil cooling lines needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 45,000.

[XXX] I was heading home from work, driving on [XXX] near [XXX] 2023 Chevy Silverado 1500 ZR2 broke down. I lost all power in my vehicle, besides brakes and steering, and had to coast into the breakdown lane. After restarting my truck, I was able to drive another mile on the highway until I lost all power again on the off-ramp. My truck was broke down, halfway in the road, and I could not start it back up to try and move it. I remained there in the subfreezing temperatures with no heat in my truck for over 1.5 hours waiting for a tow through OnStar that never showed. A state trooper eventually pulled behind me because I was blocking traffic and then proceeded to call a different tow company which arrived about 15 minutes after he called. Since that day, my truck has been at Colonial Chevrolet in New london CT waiting for a “nationally backordered” 6.2L engine. 53 days without my truck that I use for me and my business partner’s construction company, and no ETA for when the new engine will be arriving.

I was pulling into my neighborhood when my engine started rapidly thumping the higher the rpm’s got. I was able to get it to my local Chevrolet dealership. Flaherty Chevrolet in Brandenburg, Ky. They told me it had catastrophic engine failure. I’m currently waiting for a new engine replacement. They’re trying to find a new one, but are having no luck.

While driving down the highway, a message popped up stating “not suitable to shift” and I lost all acceleration and could only coast. Luckily was able to coast over to the shoulder, where attempts were made to shut down and restart vehicle. Second message came up stating reducing features to save battery. Was unable to restart and a tow was requested. Dealership reported it was unknown why or what caused it but engine was locked up. Engine only had 19k on it with just me as the owner.when purchased brand new 17 months prior.

My trucks engine failed when I was driving on the highway with my family in the vehicle. The truck lost power and struggled to get off on the side of the road. Truck has been at the dealership since 25 Nov 2024 with still no diagnostics. GM is claiming they will not replace due to lift on the truck which has nothing to do with all these engine failures. Last contact from dealership was 27 Dec 2024.

Motor seized while driving on freeway at 65 Mph. Coasted to the media on the freeway in the middle of a dividing highway. The highway patrol stopped and then left feeling unsafe. Dealer would not tear down without a $3000 release from me for labor, if not covered under warranty. This is now a federal investigation with this motor and over 86k complaints. I would also like to add, this happened to a new truck my son bought in 2021 Silverado trail boss so GM new about these motors and are still selling them!!!

Faulty coolant control valve causing reduced engine power at highway speeds and reduced acceleration caused unsafe operation on highway. Was unable to safely maneuver to right lane on highway to allow faster traveling traffic to pass. Fortunately was only about 5 miles from home and was able to operate the vehicle in "limp" mode after traffic cleared. There was no warning just during operation check engine light and reduced engine power displayed on the drivers information center. The vehicle is available for inspection with the defective part because GM can't source a replacement despite occurring nearly eight weeks ago. GM has authorized the warranty repair and is currently at a Chevrolet franchise dealership awaiting repair parts. The manufacture is aware of the issue and has accepted a manufacture engine part is the cause of the issue.

Engine seized at 330 miles. I’ve recently seen the investigation into crank bearing failure on the L87. We upfit new vehicles. This was a test truck. We pulled oil from another identical chassis with 10 miles on it and sent it in for testing to a 3rd party. At 100C/212F the viscosity was under 7 and it should be 20. It is our belief that GM has faulty bulk oil they’re putting in new vehicles.

There were no symptoms prior to the engine failure. On January 14th, 2025 while driving 58 miles per hour heard a sound that sounded like a slap on the back window. After the slap sound I noticed the engine was not running as normal. There was also a sound coming from the engine like metal rattling around. A few minutes later the check engine light appeared in the instrument panel. Had the vehicle towed to the nearest GM dealership and was informed that the thrust bearing went out which may have caused damage to the crankshaft.

I was driving and received a check engine light with “Service ESC” and traction control was disabled. Performed diagnostics and found P0300, P0304 and P0204 all relating to cylinder 4 misfire and injector issues on cylinder 4. Truck has just over 47,000 miles and may be related to the lifter issues that plague this engine design.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated while driving at an undisclosed speed, the vehicle lost motive power and decelerated to 20 MPH. The check engine warning light illuminated with the messages, “Reduced Acceleration – Drive with Care/Service Emission Systems” and “See Owner’s Manual” displayed. The contact drove the vehicle to the residence and the vehicle was then towed to the to a local dealer to be diagnosed. The contact was informed that the wiring harness was faulty and needed to be replaced. The vehicle was not repaired. The contact linked the failure to Customer Satisfaction Program: N222391510. The manufacturer was notified of the failure. The approximate failure mileage was 47,295.

I have found between the last two oil changes, I have had to add 1-1/2 to 2 quarts of oil. I first thought that maybe the oil was not refilled fully but after the second time I asked the dealer about this and they said that the engine may need up to 2 quarts of oil added between oil changes. SERIOUSLY?! I cannot believe this is normal for a new truck with less than 30,000 miles. There is no leaks in my driveway, no obvious exhaust smoke.

On June 16, 2024, my vehicle stalled on a 70 mph interstate. I was able to get to the side and attempt to restart. After ten minutes, the vehicle restarted and I received a message of "Low Battery". I drove it immediately to the dealership and advised service. The next day I called the dealership for a status update and was advised the engine seized. The vehicle had 3,212 miles on it at the time. The dealership ultimately received permission to replace the engine which took about three and a half weeks. The vehicle is simply not the same and has several issues since. One was a No Start and No Power.

at about 20k miles the valve body went out. When coming off the brake and pressing the gas the engine was jerking. The engine light came on and then started to downshift. The truck was towed to the dealer and they said a few days later it was the valve body. All the miles of the truck were highway miles and no towing was ever done on this truck.

2023 Chevrolet Silverado ZR2 purchased 7/10/2023 with a 6.2L gasoline engine - Lifter and engine bearing failure leading to complete engine failure at 5920 miles on [XXX]. Dealership has been in possession of the vehicle since [XXX]. Engine failed, leaving me stranded at an intersection blocking traffic in single digit temperatures. Due to the electronic gear shift, there was no way to put the vehicle in neutral to move it from the intersection. The tow truck driver was forced to drag the vehicle onto flatbed tow truck, possibly damaging other components in the process. This appears to be a common issue that is known by General Motors without remedy. Appears to be related to the Dynamic Fuel Management system and spring-loaded lifters that fail. The vehicle has been inspected by Chevrolet Dealer, who determined it needs a full engine replacement. There were no warning lamps or messages leading up to the failure. Vehicle drove normal for over 100 miles on the highway. Upon exiting the highway, the auto start stop feature turned the engine off at a stop light. Upon letting off the brake, the engine struggled to start back up and check engine light came on. Pulled over immediately, and upon stopping at the stop sign the engine seized and would not restart. This led to me blocking an intersection for over an hour in single digit temperatures waiting for the police and a tow truck.

Engine oil cooler lines began leaking oil at 800 miles. Oil leak appears to be at engine connection for line. Took to dealer where vehicle was purchased. They added dye to engine oil and clean up evidence of leaks. Told me to drive for 300 miles and call if it leaked again. It leaked again and dealer is non responsive to request for repair. Will try another dealer. Leak is significant.

The PCV system plugs up in below zero weather casing the main rear engine seal to blow and leak. Currently waiting for gmc to manufacture the seal as it’s been back ordered due to so many engines needing this part. Estimate is 2 months or more wait. A loud ‘pop’ was heard the day before leaking. It sounded like an object hit under the truck. Oil drops were found the next day and dealership found the leak. Gateway in Fargo, ND is the mechanic and GMC is paying for repairs. If we were to of driven for a prolonged time, the leak could have poured most of all of the oil out of the blown seal and ruined the engine. There were no warning signs. The oil pressure seemed unstable the immediate days afterwards before being looked at. It was going down and coming back up after warming. The oil began leaking faster and in larger amounts as weather warmed above freezing.
