2019 CHEVROLET MALIBU HYBRID Complaints

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.

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.

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.

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. I then witnessed several driver info messages stating things like "low oil pressure" "engine power reduced" among others and a check engine light. Amongst freeway traffic and now under no engine power and coasting I made an emergency lane change out of the passing lane and into the right lane and subsequently on to the shoulder of the interstate. Oil pressure was also noted to be very low during these events. I called a friend to pick me up off the side of the freeway and also had a local towing company get my truck and trailer off the side of the highway asap. This was a dangerous scenario and could've ended much worse. The vehicle is now at my residence and I am not sure what steps to take right now. As I am very aware of the current recall on similar models with the same engine. I have followed the issues and complaints of these trucks and suvs with the L87 6.2L engine closely. I was under the impression that my vehicle was not included in the recall and I have always been very diligent about vehicle maintenance. I've been watching my truck closely for abnormal noises, power or oil pressure loss or any other strange symptoms I have not noticed any warning signs. I even recently switched to the new dexos approved 0w-40 engine oil that GM is recommending and/or mandating. This was very sudden and scary scenario. I do have video of the engine noises if theyre. Theyre not currently formatted for this report

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.

Engine oil cooler line leaks and crimping does not hold hose tight enough and slipped off crimp fitting. line came completely off of crimp fitting and leaked all engine oil. Forced engine to be turned off and low engine oil marked on dash.

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. The contact stated that there was no oil in the engine. The vehicle was towed to an independent mechanic to be diagnosed. The mechanic associated the failure with NHTSA ID Number: 25V274000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 30,000.

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. Loss of power while in motion puts me and others at risk of an accident. Despite multiple repair attempts, the issue has not been permanently resolved. The timing chain failure is a major engine defect and not expected for a vehicle of this age and mileage. I am filing this complaint due to the safety risk associated with engine stalling and failure.

I was proceeding down the interstate when several of my dash lights came on to include the check engine light and the ABS light. My truck defaulted to a restriction of 62 mph and I lost majority of my brakes. I had to apply brute force to be able to get of the exit and to the Dealership. The dealership reprogrammed my truck’s system and charged me 300 dollars. I believe this is the same issue that has plagued many other Chevy trucks in the same model year.
