CHEVROLET Complaints

On May 2, 2026, while the vehicle was in operation, the engine suddenly shut off without warning. At the time of failure, the instrument panel remained illuminated; however, the vehicle would not restart. In an effort to resolve the issue, the battery was replaced, but this did not correct the problem. The vehicle was then towed to a local Chevrolet dealership for further inspection and diagnosis. Following their assessment, I was informed by the dealership’s service department that the engine had seized and that metal debris was present in the engine oil, indicating significant internal engine failure. I was further advised that a replacement engine has been ordered. At no point prior to this incident were there any warning indicators, abnormal noises, or performance issues that would have suggested an impending engine failure. The sudden nature of this incident raises concerns regarding the cause of failure and whether it may be related to a defect or internal mechanical issue.

The contact owns 2018 Chevrolet Equinox. The contact stated while his wife was driving 10 MPH, while depress the accelerator pedal and the vehicle failed to respond. The contact mention she put the vehicle gear shift in park and two mins later the vehicle began to work as intended.

No warning lights illuminated. A dealer was contacted. The vehicle was towed to dealer where they informed him, they will need to breakdown the transmission in order to diagnoses the vehicle The vehicle was not repaired. The contact search on the internet found two recalls relating to the failure NHTSA Campaign Numbers 20V668000 & 17V516000 (Power Train); however, the VIN was not included in the bulletin. The manufacturer was notified of the failure, and they informed the contact to call NHTSA to file a complaint. The failure mileage was 117,000.

The dual clutch transmission on my 2020 C8 Corvette has a diagnostic code of p1955. This was determined after the service light on the vehicle illuminated and it was taken to service at the dealership. Other codes that stored included p0868 and p0869 which indicate low hydraulic pressure and high hydraulic pressure respectively. The p1955 code is an internal fault that requires complete replacement of the transmission according to GM service bulletins. This bulletin also advises that no repair attempts are to be made except for complete replacement. The vehicle has not shown any symptoms currently. Gears shift normally, there are no vibrations, etc. However, the dealership advised the transmission can go into limp mode, fail completely, or damage other components of the power train at any point. This issue is known to GM. They have investigated the matter since 2021 or earlier. There have been no recalls on the transmission despite the safety risks of sudden loss of power, being stranded, or catastrophic destructive failure without warning. These pose risks to occupants inside the vehicle and other vehicles or people on the road. My repeated questioning of this matter to the dealership and GM customer service have been ignored. They only advise the cost to replace is with the owner of the vehicle despite the root cause being at the level of engineering of the part. They are unwilling to admit this failure is at the level of a manufacturing/engineering defect as a financial cost mitigation strategy. The Issue with sudden failure of the transmission in these vehicles are widely known, investigated, and occurring at a high rate, especially in early model C8 Corvettes.

This truck has a recall on it but by specific VIN numbers mine doesn’t fall into the VIN number but had the same catastrophic oil cooler line failure, which is in the recall which caused the engine tool expire with 40,000 miles on it. Truck is like brand new General Motors will not honor the warranty even though it’s the failure that’s in the warranty makes no sense.

2020 Chevrolet Traverse started to shudder and hard shift between 25 to 30 miles per hour. Vehicle only has 64,925 miles on it (4,925 miles above warranty). Vehicle was taken to garage and told the torque converter along with valve body was needed to be replaced. The torque converter malfunctioned right after warranty expired due to mileage and could have left my family stranded on the side of the road. The components have been inspected by Chevrolet manufacturer and they deemed they needed to be replaced and replaced them. No lights or anything came on the only sign was the shudder and hard shift which if not taken in immediately could put the owner past the warranty mileage. Vehicle was purchased brand new and routine maintenance conducted.

Transmission shudder, car was recalled in 2021. Now it’s backing doing the same thing in 2026

The steering wheel locks and stiffens on turns to the left or right refusing to come back to center on its own. In the middle of the turn the wheel locks up. Been told by multiple dealerships and forums I've read online it's a known issue with the car needing a steering gear replacement. A job that costs $4-5k per GM based on labor. There's no warning lights. GM has reproduced issue And based on this forum multiple accounts of this have happened to others [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My son was driving his 2020 Silverado Trail Boss (50,000 miles) when suddenly the brakes were inoperative. He had to drive around several cars to avoid collision finally swerving into the parking lane and using the gearshift lever moving the transmission into park to stop forward movement. He had no warning lights or any indication the brakes were going to fail. The truck was towed to Harbor Chevrolet on Long Beach, Ca. They diagnosed the problem as a “software update” and this was “rare”. They seemed along with GM customer service seemed not to be very concerned about the problem and just gave me some GM Reward points. We are afraid to drive the car at this point.
