2019 Chevrolet Silverado 1500 — Known Issues & Recalls

Your engine made clunking or clicking sounds before losing power on multiple occasions while driving. The dealer found that the engine rod bearings failed and replaced them along with the engine block, but the same problem returned about five months later. The second time, they diagnosed an exhaust manifold leak and replaced it, but the issue happened again just two months after that repair. This problem started around 103,000 miles on your vehicle.

Your engine is consuming oil at an unusually high rate—about 1 quart every 700 miles. Even though your truck has only 41,000 miles on it, this level of oil consumption suggests an internal problem like worn piston rings, valve seals, or a gasket leak. A mechanic will need to inspect the engine to find the source and determine if internal repairs are needed.

Your engine's oil cooler line is leaking, which means oil may be escaping from the connection that cools your engine oil. You may notice oil spots under your vehicle or a drop in your oil level if the leak isn't addressed. This should be inspected and repaired soon to prevent engine damage from low oil levels. The fix will likely involve replacing the leaking oil cooler line or tightening the connection.

My husband, [XXX] son, my [XXX] mother-in-law, and I were traveling on the expressway at approximately 70 miles per hour in our 2019 Chevrolet Silverado 1500 with the 5.3L engine when the dashboard suddenly lit up with warning lights and alarms. My husband looked in the rear-view mirror and saw a large amount of smoke coming from the truck. We immediately had to cross two lanes of heavy traffic to reach the shoulder and get off the roadway safely. When I opened my door, I could see that engine oil was pouring from the truck and running down the expressway. We were stranded on the side of the expressway for over an hour before my brother was able to come pick us up. The tow truck company advised that it would take several hours before they could arrive. During that time, vehicles continued traveling at highway speeds and did not slow down despite our disabled truck being on the shoulder. The truck was shaking from the wind and force of cars and trucks passing by at high speeds. This created an extremely dangerous situation, particularly with our [XXX] child and my elderly mother-in-law in the vehicle. The truck was eventually towed to a local repair shop, where the mechanic determined that the engine oil cooler line had broken at the crimp, causing a significant oil leak. The repair required replacement of the oil cooler lines and related components at a cost of $2,109.92. Had we continued driving even briefly, the engine likely could have been severely damaged or destroyed due to the rapid loss of oil. This appears to match the known issue described in GM Customer Satisfaction Program N212326940 regarding oil cooler lines detaching from the crimp on 2019 Chevrolet Silverado trucks. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Incident Description: While driving at highway speeds, the oil cooling lines on my vehicle suffered a catastrophic failure, resulting in a total loss of engine oil within seconds. To ensure my safety and avoid being stranded in high-speed traffic, I proceeded less than a quarter-mile to reach the nearest exit. During the cooling process after the vehicle was stopped, the engine seized due to extreme thermal damage caused by the sudden lack of lubrication. Safety Risk: The sudden and total loss of engine oil at highway speeds presents a significant safety hazard. It creates an immediate risk of sudden engine stall or seizure while in traffic, which could lead to a high-speed collision. Furthermore, a high-volume oil leak onto hot engine components represents a severe fire risk. Technical Evidence & Manufacturer Response: There are existing Technical Service Bulletins (TSBs) for this specific vehicle model that explicitly identify these oil cooling lines as a known failure point. These TSBs state that failure to replace these lines can lead to the engine becoming non-functional. Despite this documented manufacturing defect and the clear safety implications of a sudden engine failure on a highway, Chevrolet has refused to provide a remedy, insisting that the engine replacement be paid for out-of-pocket. Requested Action: I am requesting that the NHTSA investigate this known defect for a potential safety recall, as the failure of these lines constitutes a predictable and dangerous loss of vehicle power and potential fire hazard.

Vehicle info: 2019 Silverado 1500 6.2L engine with 66,xxx miles. On 3/1/26 While towing my small snowmobile trailer I was driving on I-90 with cruise control set at 65 MPH. Very suddenly and shockingly I heard an extremely loud knocking noise from the engine.

Your truck's dashboard displayed a "Low Oil Pressure" warning while driving, and you were forced to shut off the engine and have it towed. The dealership found the engine was seized and would cost over $22,000 to repair. Chevrolet had issued a Customer Service Program acknowledging that 2019 Silverado 1500 trucks can have defective crimped oil coolant lines that separate and cause severe oil loss—a problem made worse by cold weather—but GM has refused to cover the repair, claiming your vehicle's identification number is not on their repair list despite the known issue. The repair would involve replacing the oil coolant lines and potentially rebuilding or replacing the engine.

I have had to put my vehicle in the shop for transmission repair. The first time it was in the shop for over a month to only get it back and have the same issue. Now the shop is telling me that GM is having a system glitch and they are unable to program it.

Your truck's engine has shut down completely at least 20 times since December 2024, causing total loss of power to steering and brakes while driving — a serious crash hazard. The engine light doesn't always appear after restart, making diagnosis difficult, and even after the dealer replaced two oxygen sensors in March, the shutdowns continued with four more failures in one day. This recurring problem has made your truck unsafe to drive, and you haven't received follow-up support from Chevy service.

My 2019 Chevrolet Silverado has experienced repeated engine issues, including a confirmed timing chain failure. The vehicle has been taken in for repairs approximately 6–7 times for the same or related engine problems. Most concerning, the vehicle has stalled while driving, creating a serious safety hazard.

Your Electronic Stability Control (ESC) warning light came on while driving at 35 MPH on the highway, and your truck started vibrating constantly. The vehicle continued to run normally otherwise, but the vibration and warning light persisted. Your dealer was unable to diagnose or fix the issue. Resolving this will likely involve diagnostic scanning to identify the underlying fault in the ESC system, which may require sensor replacement or electrical repairs.

Your truck's oil cooler lines are leaking oil, which is a reported issue affecting multiple GM vehicles. You may also experience transmission, engine, electrical, and brake problems. Fixing the oil cooler line leak will likely require replacing the damaged lines and seals.

Your truck is losing oil faster than normal, a problem that started in September 2023 and continues today even after the engine was replaced in 2025. The transmission failed about 3-4 months after the engine replacement and was also replaced. You're only alerted when the oil level gets critically low, and the leaking oil is mixing with gasoline, suggesting a fuel pump issue that now needs replacement. Fixing this will likely require diagnosing and replacing the fuel pump, and possibly addressing the underlying cause of the excessive oil consumption.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving 15 MPH and turning left, the low oil pressure and several unknown warning lights illuminated. The vehicle was pulled over into a parking lot.

I am reporting a catastrophic internal engine failure in a 2019 Chevrolet Silverado 1500 at 87,600 miles. Prior to this event, there were NO warning lights or symptoms. While traveling alone during the holiday on a remote, one-lane road with no shoulder, the vehicle suddenly suffered a loss of power. Every warning light on the dashboard illuminated at once, followed by shaking, misfiring, and loud knocking from the engine. Because I was on a one-lane road with no place to pull over, this created an immediate safety hazard for me and oncoming traffic. I had the car towed to the dealership ( where I bought the truck) confirmed the failure was a collapsed lifter and scored camshaft (which i found out to be a known design flaw in the 5.3L DFM engine). The dealer said it was not under warranty. I felt held over a barrel by the dealership; they initially provided an inflated quote and told me it would cost approximately $1,200, not including tax and shop fees, just to put the engine back together if I wanted to tow it elsewhere for a second opinion. I was forced to pay over $8,395 under protest just to regain use of my primary vehicle after 42 days of downtime. Upon completion, the dealer provided a "Lifetime Warranty" on the replacement parts. This is a tacit admission that these components were never intended to fail during the life of the vehicle. GM refuses to include this vehicle in its coverage list, treating a dangerous engine stall as a simple "out of warranty" repair. This is a systemic safety defect that requires a mandatory recall expansion before it results in a terrible accident. My understanding is that a Class Action lawsuit, Harrison vs. General Motors, for this same thing, but they say my car is not in it, i should have been put on notice for this so I could protect myself.

Odometer Fraud. The contact purchased a 2019 Chevrolet Silverado 1500. The contact stated that upon arriving to the DMV parking lot to register the vehicle, the contact compared the VIN the dealer had initially provided prior to the purchase, to the VIN listed on the title and on the vehicle. The contact discovered that there was a VIN discrepancy. The contact contacted an independent mechanic retrieved a Carfax Report of the VIN listed on the title and informed the contact that the actual vehicle mileage was 182,041. The vehicle was a private sale. At the time of the purchase, the vehicle mileage was 72,409; however, the Carfax Report confirmed that the actual mileage was 182,041. The seller was contacted but failed to respond and had ended communications with the contact.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated while driving approximately 30-35 MPH and exiting the interstate with a speed limit of 55 MPH, the instrument panel, check engine, stability control, and several other warning lights illuminated. The vehicle felt like there was a misfire coming from the engine. The contact pulled into the nearest parking lot and turned off the vehicle. The vehicle was driven to the dealer, while not exceeding 25 - 30 MPH. The dealer diagnosed the vehicle and determined that the camshaft was damaged, and the valve lifters had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The manufacturer opened a case regarding the failure. The failure mileage was approximately 97,000.
