Your vehicle lost communication with the OnStar system while driving, and you believed your brakes failed along with other safety systems becoming inoperable. The dealer was notified but didn't diagnose or repair the issue. This happened at 114,000 miles, and Chevrolet has been made aware of the problem.

Your 2021 Tahoe is unexpectedly shifting into neutral, losing engine power, and stalling while driving — sometimes without warning — creating dangerous near-miss situations with other vehicles. This has happened multiple times since March 2025, and your dealer has replaced six different components based on error codes, but the problem keeps returning within days to two months. The dealership and Chevrolet Customer Care claim the vehicle is safe, but you've spent over $6,000 on repairs and don't feel confident driving it. Identifying and permanently fixing the underlying electrical or fuel system fault will likely require comprehensive diagnostic testing to find the root cause rather than replacing individual parts.

Your truck started making knocking noises and acting rough while idling, then multiple warning lights appeared on your dashboard: the ESV service light, engine light, and forward collision avoidance system failure light. Your vehicle has lost significant power and you're noticing a burning electrical smell from under the hood. The truck is not drivable for normal use and needs immediate diagnosis to identify what's causing the electrical and engine issues.

Your truck's sound system cuts in and out intermittently, including the audio alert for your turn signal. Because you can't hear the blinker click, you have to look down at the dashboard to confirm the blinker is activated, which creates a distraction while driving. The issue likely involves a faulty electrical connection or module controlling the audio system and turn signal sounds.

Info center with radio, vehicle info, on star keeps going black screen. When this happens I loose all control of info center and on star goes out where no location would be available if the vehicle was in an accident. This is safety concern because with no automatic notifications of accident no one would know if vehicle was in an accident. The vehicle has been to dealer 4 times for this problem since February of this year. Each time the dealer says it needs another update each time. GM is having this issue with many of the Vehicles like this Tahoe. On Star is also aware of the issue too. GM knows there's an issue but now they are saying I have to pay for an update because I am out of my extended warranty even though this has been an ongoing problem which started when I was in warranty. This has to be a programming issue that they need to fix. The vehicle has to be shut off for up to an hour for screen and controls to come back on which is safety issue because no way to change any settings for vehicle and safety backup because of no on star.

When driving the car just stops losing power then the car immediately shuts down and stops driving. I had to call a tow truck when it’s taken to the dealership the fuel pump power control module is faulty. This is a 2021 Tahoe they had to replace the fuel pump, power control module, and this vehicle should not have to be replaced. Chevrolet/GMC knows that these modules will make the vehicle stop wherever it is driving. I happen to be on a freeway going 70 mph and could have been killed. They have not put a recall out to have these modules replaced in any SUV. This is a danger for any driver on the road. This is a lawsuit waiting to happen for people. You know that they are aware this is happening because they paid for the tow and replaced this part that is not warranty now for free. Yes, great that it was paid for but thankful I did not lose my life as I could’ve been rear ended when my car shut down going that fast in the middle of the freeway I am begging that they please put a recall so no one gets injured or killed.

To Whom It May Concern, I am writing to formally report serious defects with my 2021 Chevrolet Tahoe (VIN: [XXX] ) and to request assistance with repair costs. Approximately six months after purchase, when the vehicle had about 22,000 miles (I bought it used with around 19,000 miles), the battery and electrical system failed. I brought it to the dealer and was told there was no issue; they only performed a jump start. Two days later, the vehicle broke down in the middle of the road. I had to pay for a tow truck and replace the battery completely out of pocket. More recently, at about 92,000 miles, the vehicle developed severe engine problems. A certified mechanic diagnosed collapsed AFM lifters and camshaft damage. The repair requires OEM GM parts and costs approximately $4,500. This issue is widely reported by other GM owners with 5.3L AFM engines and is known to be a manufacturing defect, not a maintenance problem. Please note that my Tahoe has been well maintained, with oil changes always performed on time and using the correct oil and service intervals recommended by GM. Despite this, the vehicle has experienced repeated and costly failures that create unsafe driving conditions. I kindly request that GM review my case and provide assistance with covering the repair costs or reimbursement, given that these issues are the result of known defects and not owner neglect. I look forward to your prompt response. Sincerely, [XXX] [XXX] 33032 [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2021 Chevrolet Tahoe original owner. Fuel control module failures. 1. Failed on 6/29/21 at 5,068 miles. Dealer replaced with GM Part #13537053. 2. Failed on 8/15/22 at 12,130 miles. Dealer replaced with GM Part #13544060 3. Failed on 8/1/25 at 41,247 miles. Dealer replaced with GM Part #13554821 On each failure, vehicle was unable to shift to neutral, power remained on, electrical component began shutting down to conserve power, left stranded and required towing with rear wheels being dragged locked up onto tow truck. Once power was shut down, could not operate windows or lock doors other than keyed driver's door. Th entire failure mechanism puts the driver in an extremely unsafe situation. Recall notice #21V739000 was issued on 9/23/21 with to impacted notified owners on 10/14/21. Did not receive this notification since first failure was prior to recall and assume GM considered vehicle repair completed. Note that the fuel module part number has changed 3 times in my case, but Part # 3554821 replaces 5 other listed part numbers. Is this the 6th iteration or of this part? What is the root cause of the fuel module failure? Is it the module itself failing or an electrical issue that causes the fuel module to short out and fail. GM/Chevrolet is not solving this issue. With 3 failures of the same component, this is a lemon and I have no comfort or confidence using this vehicle. When will the next failure occur and what unsafe situation will this leave me stranded in? Read this issue applied to 2021 and 2022 GM full size SUV's and now reading issues through the 2024's. Unacceptable and poor quality. GM needs to be held accountable to solve the root cause of these failures and stop putting a replacement band aid on the problem.

We are apart of the safety recall with the potential brake and engine issues, we have contacted the dealership and they have NO remedy at the current time for our defective vehicle. We contacted GM to request a buy-back due to the safety issues with the vehicle, told we did not qualify BUT they have no remedy for our defective truck. We do not fell safe in the vehicle, the brakes are sticking and the engine is making weird noises. We are currently seeking legal representation because we are being forced to drive around our family of 5 in an unsafe vehicle with NO remedy or option to trade it in.

Failed OTA Update to information center (Radio) has caused radio unit and screen to become inoperable. Blinkers do not sound when on, warning sounds when backup camera are in use no longer work, along with cross traffic warning due to this. It should be noted we did not consent to the OTA update, and would have not wanted the update as it has caused damage to this system. GM know this is an issue and has refused to fix this.

Instrument panel has failed twice and is unresponsive. The gauges move and stay to the left after moving left to right. All lights begin to cycle through error messages. I have video of the issue both times it happened. When it occurs, you don't know your speed you have to guess, the full tank reads empty etc., and it is dangerous to back up. The vehicle has been diagnosed by one independent mechanic and is currently at the dealership. There was no warning before the instrument cluster failed other than a cycling through of warning messages service transmission check 4X4, service suspension system, service Power Steering Drive with care. -The center screen goes in and out. -When in reverse, the rear camera is black, the screen blinks intermittently. - Dealer has stated that the wires are put on incorrectly- if that is the case, I am not sure who would have done that other than the manufacturer. -previously reported there was a strong gasoline smell in the cabin that made it really hard to breathe. Dealer corrected. Right passenger side is intermittently wet with no cause from the interior creating stale smells, making it hard to breathe. It is important to note this is the side where the electrical wires are "put in incorrectly" according to the dealer. I also have a video of what occurs

Fuel module failure while driving, engine stalled and would not restart.., while at highway speed. Very dangerous situation!!!!! Tahoe was towed to dealership kept for. 1day. Chevy dealer replaced fuel module. We have owned 6 different Tahoes starting with the year 2015 to 2024. The fuel module failed on the 2021, 2022 and now the 2023!!!!!!! Makes us question if we should purchase a new Tahoe every other year? Seriously considering other car brands such as Ford, BMW or other more reliable brands!!!!

On 2 occasions the dash lights and gauges do not turn on when the vehicle is on. The first time this happened I was driving and was no longer able to see my speed or any other details provided by the gauges. We changed the fuse and it seemed to work for 1 day. The next day I turned the vehicle on, was able to drive but none of the dash features were functioning again. Will be taking to dealership when available scheduling to have it evaluated.

vehicle infotainment system will randomly "restart" or shut off completely when vehicle is being drove, but will still be playing music also all time and temperature (outside temp) will freeze when this happens. it also make the battery drain when this happens. the only way to get the screen to come back on weve tried is to disconnect battery. weve replaced the battery, weve had a chevy dealership look into it. no one can figure out what is happening. Now it is happening more and more. we also do not receive updates anymore to the infotainment system. the dealership had to manually do it a year ago. also will not keep our proifile signed in at all. always says were stuck in guest mode. says we have full storage when there is not any apps downloaded.

My vehicle performed an update without my knowledge. When I got back into my vehicle after a quick stop the infotainment system said "Update Failed - Return to Dealer". I did so and was informed that a reprogram was attempted but failed so the entire system needed replaced. There is active recalls I'm told on newer model vehicles with the same issue but mine is not included. So, after the OTA update I didn't ask to take place I'm stuck paying $1,300 for a new infotainment system. I called GM who basically told me without there being a recall there was nothing they could do.

Car would not turn back on, and then lights for fuel machine error started coming on. Car sat there trying to turn on, lights off, and then would say push start button, but nothing happened. Car began to shake and continued to try to turn on, yet nothing happened. Car was towed to home, sat for an hour and then started again, check engine light remains on.

WHAT FAILED: Main Radio. SAFETY CONCERNS: GM sent an over the air update to car around July 5, 2024 and the update broke the whole radio system to my car. I now have no access to OnStar, bluetooth for phone safety, maps, blinkers on side mirrors, radio etc. Dealer mentioned it is a very common problem with this particular GM product and the over the air update to cars. When I asked to turn this feature off so it doesn't happen again it is not an option. The Chevrolet Dealer and a sound system specialist has inspected vehicle. Sound System specialist said this part may only be replaced by the dealer as it is the high end radio system. There was no warning of the update happening. The car was in great condition until this update was pushed through in the middle of the day. Now I am being quoted $2000 to fix it with no guarantee that it wont happen again.

I am experiencing loss of power just like the recall shows for campaign 22V036000 powertrain. Engine stall in the middle of the street just like it shows for the fuel system 21V73 9000. I have stalled in the middle of the street including today four times and a month. The dealership can’t seem to find what’s wrong. Nor other places. I don’t think they are looking hard enough at the dealership. I almost got killed by another car going at least 65 mph while I was stuck in the middle of the street at a stoplight.

The airbags failed to deploy in my 2021 Chevrolet Tahoe after being involved in an accident where another vehicle t-boned my vehicle on the passenger side front end to rear end causing severe damage and pushing my vehicle with great force. A police report was taken by officers that responded to the traffic accident. A claim was filed with my auto insurance and my 2021 Chevrolet Tahoe is currently being repaired as it was not deemed a total loss. Myself and my passengers were injured and received and continue receiving medical treatment for our injuries; our safety was definitely placed at risk. Before being involved in this accident, warning alerts/lamps would appear on the vehicle’s dashboard indicating to “service the safety restraint system” and also to “open then close passenger window” which in turn led me to take the vehicle in for service however the dealer said it could not be duplicated nor did the computer show any alerts. After the accident, I Contacted General Motors and filed a claim for the non deployment of the airbags, they in turn are conducting their investigation.

We barley made if off the hwy`s left side when the Tahoe died. Would not start back up and locked in park. Had to be towed on a flat bed dragged up the bed and brought to the Chevy dealer who confirmed the fuel pump power control module failed and replaced under warranty.

The truck had an airbag malfunction notice on the information center. We took the truck to the dealer and was told that it was an electrical problem with the airbags. That the only way to have it covered under warranty was for the vehicle to be under the bumper to bumper warranty. The truck at the time the mileage was 39844. We had the truck fixed since it was a safety issue. It cost $420+ to fix it. We feel that it should have been covered due to a safety issue.

We were driving down the road and as I tried to accelerate the car would not go. Then I realized the car said push to start. My husband tried to push the neutral button and told me to restart it but I said you have to push the brake. All this is happening as we are coasting down a main road with speed limits of 55mph and my family is in the vehicle (including 2 toddlers in the back seat). Once we coast to a gravel area off the road I push the brakes and try to restart. My dash goes all black and I try to restart. It tells me battery low push to start. The starter engages and stays engaged until I push the start button again to turn off. The screen tells me it is shutting down functions to save battery. The check engine light is on. We tried 3x with same results. Finally we get out and my parents come to us. Within 15 mins of the initial incident, my husband and dad get in and start my vehicle. My dad suspected the fuel pump. The fuel was right under 1/4 tank but not low enough for the fuel light to be on. They drove to the fuel station, approximately 2 miles away, filled up the tank and drove it to an auto parts store who connected it to a diagnostic machine and it read fuel pump. They drove it back to my home, approximately 2 more miles. The check engine light is still on. I will call the dealership tomorrow. The vehicle has 23,000 miles and is still under manufacturer warranty.

It was stuck in Park, the electronic Parking Brake could not be disengaged, the door locks could not be operated and left unlocked, no lights, no warning lights, the emergency lights did not function, no horn, and most everything else. The only things still working were the radio, the driver's side powered seat would move, and the light came on for the Parking Brake. The battery was fully charged. I also started receiving messages through my Chevrolet APP that the vehicle had no air in the tires, no oil in the engine, and many other items that needed servicing. I am not sure what exact components or computers have failed yet. GM could not find any dealer to render aid and come to my location to reprogram the vehicle. It had to be towed to a dealer.

The dashboard for the vehicle loses all power and does not regain power/connectivity. I've had this problem "fixed" 5 times by the Chevy dealership and the issues continues. They've replaced the entire dash, checked electrical components, changed out the electrical bank, and the issues continues. Driving down the road at 65 mph to have your dash go out is not only terrifying but extremely dangerous! I have no idea how fast I'm going, how much gas I have, no situational awareness related to vehicles that are close by... the ENTIRE dash goes out. This is a brand new 2021 Chevy Tahoe...

Traction control and forward collision warning lights stared to go crazy in August 2021 (3800 miles), five months after buying my Tahoe. Sales rep indicated his new 2021 Silverado did the same and he was able to get it to reset by turning off and restating his engine. So I did the same and thought my issue may have resolved itself. Yesterday, the warning lights started to go haywire again (6700 miles) This time my vehicle felt as though it was going to stall and was making a clicking noise under the hood. The warning lights continue to flash regardless of how many times I turn on and off the engine. The engine also revs loudly.

I purchased a 2021 Chevy Tahoe from Autonation Chevrolet 11-3-2020. I have taken my Tahoe to the service department numerous times - as my truck has had a stubborn service safety restraint system warning error code that continues to come on and off. I have taken it to have all recalls serviced as per recall request. The service safety restraint system warning code has not been corrected after more than 5-6 visits if not more as not all visits have been logged properly. I have had this truck for less than 12 months and have experienced too many conflicting issues. I do NOT feel safe driving my Tahoe with the SRS light on. There's obviously a malfunction that you all have not been able to figure out. This is extremely dangerous!! What if I were to get involved in an accident or collision and my airbags do not deploy? I may have a problem with the airbags themselves, a loose wire, a faulty seat belt buckle, or a problem with the engine control unit which is causing the airbag warning to come on. There is obviously a major problem. I am putting my children and family at risk. I have not received an email or phone call from anyone at Autonation Chevrolet. The service safety restraint system warning code has come on and off 7x since I was last at the dealership (9/10/21) and I have pictures to support.

We have owned this 2021 Chevrolet Tahoe for a little less than a year. Since acquiring this vehicle, there have been multiple safety recalls and we have had to get the vehicle serviced 3 times due to electrical issues. Now for the major safety issue, was out of town waiting at a red light in a turning lane. As we were waiting, the Tahoe spontaneously turned off. All of the indicator lights on the dashboard were illuminated and my husband tried to restart the car but the engine just kept turning and the car would not start. We put the hazard lights on and wanted to get the vehicle out of the road where there was active traffic. However, the vehicle was unable to be shifted to neutral so we were stuck and also important to note the hazard lights were not working. We towed to the nearest dealership and tow driver had to apply WD40 on the ramp to get the truck off since it wouldn't shift to neutral. At the same time, my husband received an email from OnStar "An issue with the Engine and Transmission System in your 2021 Chevrolet Tahoe has been detected." Now being told by dealership this was caused by a fuel pump module cut off, causing the car to go into "limp mode" so who knows what is true. I do not feel safe driving this car nor having my kids in it. This would be a very different conversation if this happened on a highway. This vehicle should be recalled because someone gets killed.

VEHICLE WILL NOT START. ONLY 6900 MILES. BATTERY FINE, LIGHTS AND RADIO WORK, WINDOWS AND TAILGATE WORK. CAR TURNS OVER, BUT JUST WON'T START. READ MANUAL, DID EVERYTHING SUGGESTED. CLEARLY AN ELECTRONIC ERROR. AND, BECAUSE VEHICLE COULD NOT BE STARTED, IT COULD NOT BE PUT IN NEUTRAL. TOW DRIVER HAD TO DRAG CAR ACROSS PAVEMENT ON FLATBED. COULD NOT BE GOOD FOR BRAKES OR ANYTHING ELSE DOWN BELOW. WHEN ARRIVED AT DEALERSHIP, COULD NOT GET TAHOE OFF FLATBED. WINCH ONLY PULLS UP ONTO FLATBED, DOES NOT PUSH BACKWARDS. OILED THE FLATBED AND SHOOK THE ENTIRE TOW TRUCK BODY TO TRY TO GET IT TO SLIDE DOWN. NO IDEA WHY THIS HAPPENED. BUT A COUPLE OF MONTHS AGO SAME THING HAPPENED TO A FRIEND'S GMC VERSION. CLEARLY ELECTRONIC FAILURE IN BAND-NEW CAR.
