CHEVROLET Complaints

The contact owns a 2018 Chevrolet Malibu. The contact stated that on several occasions while driving at various speeds, the message "Engine Power Reduced" was displayed, and the check engine warning light was illuminated. The contact stated that after 20 minutes of consecutive driving, the vehicle drove sluggishly and lost power. The vehicle was taken to an independent mechanic, where the check engine warning light was reset, but the diagnostic result was not provided. The vehicle was then taken to another independent mechanic where a diagnostic test could not be performed because the machine was unable to remain connected to the ECM. The vehicle was then taken to a dealer, but was not diagnosed. The contact stated that an unknown software update was performed; however, the failure persisted. The vehicle was taken to the same dealer where it was diagnosed and determined that three fuel injectors were weak, there was a crack in the lower oil pan, and that the oil pan needed to be replaced. The vehicle was partially repaired by replacing the oil pan, but the fuel injectors were not replaced. The contact stated that on several occasions during the summer, after turning the vehicle off, the message "Shift to Park" was displayed. The vehicle was turned on and the shifter was shifted several times and was turned off several times until the correct gear selection was recognized. The manufacturer was not notified of the failure. The failure mileage was approximately 116,000.

The contact owns a 2026 Chevrolet Trailblazer. The contact stated that while driving at various speeds, the vehicle failed to properly shift into gear while the gear shift lever was in use. The check engine and another unknown warning light were illuminated. The vehicle was towed to a local dealer, where several undisclosed fault codes were cleared. The vehicle was towed back to the same local dealer, where it remained for further investigation. The contact was informed that the transmission might need to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 100.

The frame of my 2018 Chevrolet Silverado 1500 has rusted through to the point of failing Maine state safety inspection at only 41,000 miles. A licensed Maine inspection station identified structural frame corrosion and determined the vehicle is unsafe to operate. A Chevrolet dealer confirmed the frame rust and stated the truck must have rusted sections cut out and welded to be made roadworthy. The vehicle is available for inspection upon request. Safety risk: A rusted-through frame on a pickup truck is a serious structural defect. Frame failure while driving could cause loss of vehicle control, separation of suspension or drivetrain components, or catastrophic structural collapse, particularly at highway speeds or under load. The vehicle is currently unregisterable in Maine due to this safety failure. The failure has been confirmed by both an independent licensed inspection station and by a Chevrolet dealership service department. This failure is consistent with a known manufacturing defect documented in GM Technical Service Bulletin 19-NA-255, which acknowledges that the wax coating applied to the frames of 2011–2024 Silverado and Sierra trucks was improperly applied by a third-party frame supplier, causing the coating to peel and exposing bare steel to premature corrosion. GM has issued this TSB but has not issued a recall, and Chevrolet dealers are not consistently performing the repair. I contacted GM Customer Assistance to request goodwill repair and was refused; the representative also declined to open a case. There were no warning lamps or dashboard messages prior to discovery, as frame corrosion is not monitored by vehicle systems. The defect was identified visually during state safety inspection. I am requesting that NHTSA investigate this defect pattern and consider a recall, as was ultimately ordered for the similar frame corrosion defect on Toyota Tacoma trucks.

The contact owns a 2025 Chevrolet Blazer. The contact stated that while driving at an undisclosed speed, the Forward Collision Avoidance system activated while there were no objects or persons in front of the vehicle. The failure reoccurred on several occasions. The Forward Collision Avoidance warning light illuminated, and the message "Approaching Person" was displayed. The vehicle was towed to a dealer to be diagnosed; however, the failure was not duplicated. The vehicle was not diagnosed or repaired. The vehicle was taken back to the dealer to be diagnosed; however, the dealer was unable to duplicate the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was approximately 4,100.

The contact owns a 2017 Chevrolet Trax. The contact stated that after the vehicle sat for a while on several occasions and was then driven, there was smoke coming from the engine compartment. While driving on those occasions, there was an abnormal ticking sound coming from the engine compartment. The vehicle was taken to a dealer, and DTC: P0171 was retrieved. The vehicle was repaired, but the failure reoccurred approximately six months later. The vehicle was towed to the same dealer where DTC: P0300, US669T, 41121, and P0301 were retrieved. The ignition coil and spark plugs were replaced, and the vehicle was repaired. The contact stated that four months later, after the vehicle sat for a while, while driving at an undisclosed speed, there was smoke coming from the engine. The vehicle was then taken to a dealer where it was determined that there was an oil leak coming from the turbocharger return line and a fractured tube inside the engine. The oil connector and line were replaced. The vehicle was repaired, but the failure reoccurred two days later. The manufacturer was not notified of the failure. The failure mileage was approximately 80,641.

The contact owns a 2012 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed and stopping at a stop light, the accelerator pedal was depressed, and the accelerator pedal became stuck, and the engine unexpectedly revved to 5,000 RPM. The contact stated that the accelerator pedal failed to release. The brake pedal was depressed several times within 15 seconds, and the engine stopped revving. No warning lights were illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 146,250.

The entire infotainment system has gone black. Nothing shows on the screen. This is a safety issue as it does not show blind spot monitoring, heads up display, lane change warnings, allow hands free calling, gps, and much more. None of the safety features are available with a trailer hookup as well. We have taken it to a certified Chevrolet dealer who has said the truck was the 6th one that they have placed an order for in just over a week. The infotainment system is currently on back order which makes operating the vehicle concerning with its proper safety features.

The contact owns a 2022 Chevrolet Tahoe. The contact stated that while driving at various speeds, the check engine warning light was flashing, and the vehicle was shuddering. The vehicle was taken to the dealer several times, and it was diagnosed with a misfire in cylinder #5. The dealer informed the contact that the engine was taken apart during the diagnostic process, and the vehicle was repaired; however, the contact expressed doubts that the engine was taken apart or repaired because the dealer had only sent pictures of the exterior of the vehicle to the warranty company. Additionally, the failure recurred while driving. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 85,000.

Sometimes when I am backing up, the breaks will slam on. Back in 2025 first I noticed, but thought it was human error, just wasn’t sure. After it happened more than a couple of times in 2026, I realized it wasn’t me and must the safety warning system? I googled after it happened this month and (phantom breaking) popped up for the Chevy equinox. I Have an appt. With Chevrolet to check it out in 2 weeks. Scary when it happens. I’ve only noticed it so far when backing up. If it were to happen other than in a parking lot, that could be dangerous, especially if I am going faster.

On April 10th, while traveling approximately 7 hours from home on a very busy highway in [XXX] , my 2023 Chevrolet Tahoe (6.2L engine) suffered a complete and catastrophic engine failure, requiring a full engine replacement. The vehicle had to be towed and I was left stranded with no transportation. Prior to this failure, I had brought the vehicle to an authorized GM dealership for a recall inspection specifically related to the 6.2L engine on September 9, 2025 with 36,162 miles. The dealership technician inspected the vehicle and informed me that my engine was not defective and cleared it. Shortly after that inspection, the engine suffered a total failure at 46,6xx miles on the vehicle. I am currently leasing this vehicle at approximately $1,100 per month and have been without the vehicle for an extended period while it sits awaiting repair. GM customer care has been contracted and has indicated they cannot move forward with a buyback claim because the BBB is not taking my case because the vehicle is older then 2 years old which I know is a false legal claim. This is a serious safety concern, a catastrophic engine failure at highway speed poses significant risk to vehicle occupants and others on the road which appears consistent with other reported failures. I am aware that NHTSA has opened Recall Query RQ26001 investigating the adequacy of GM's remedy under recall 25V-274. My experience is consistent with the 36+ complaints that triggered this investigation, engine failure occurring after an authorized dealer performed the recall inspection and cleared the vehicle. I am requesting this complaint be added to the RQ26001 investigation file. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
