CHEVROLET Complaints

Intermittently I will receive a dashboard message reading “shift to park” after I park the vehicle and do shift to park. This is a known issue with this vehicle across several years identified as “a known issue caused by a faulty switch in the shifter assembly failing to detect when the car is in Park”. GM has identified and found a solution to this problem by replacing the entire shifter assembly at the owners own cost. This malfunction has the potential to cause great harm. Potentially the vehicle could roll if the engine/system does not identify that it is in park. This could cause very expensive damages or even take a life. The vehicle also remains in accessory mode which drains the battery and can become even more costly for the owner at no fault of their own.

telematic defective waiting 7 weeks still no eta... safety issue if battery loses power

Vehicle was determined to be unsafe to operate per inspection performed by Mike Maroone Chevrolet on 8/26/24 immediately after I purchased from Rocky Mountain Auto Brokers in Colorado Springs on 8/8/26. It was discovered by customer immediately after sale that bank 2 catalytic converter was restricted internally (after Rocky Mountain failed to correctly diagnose and repair 3 times before and after purchase). Customer discovered emissions warranty extension and took to Maroone Chevrolet. After warranty repair inspection of vehicle determined it was not safe for customer to pick up and drive vehicle and generated a report and video showing front suspension damage so loose that could cause crash and vehicle was towed back to Rocky Mountain for repairs. Rocky Mountain has failed to provide any documentation on these repairs and many subsequent repairs including transmission replacement after many written requests. Customer cannot verify if vehicle repairs brought vehicle back to a safe condition. Almost anll repairs by Rocky Mountain has failed resulting in missing bolts, bolts falling out after transmission replacement As well as failure of many CV Axel replacements documented in their own records. Extended Warranty Company also refuses to provide documentation of transmission replacement after they supplied the part (transmission) to Rocky Mountain for installation. Customer cannot verify if in fact transmission was replaced as it was painted black. Any warranty on replaced transmission cannot be verified and they also have refused to provide documentation or serial number verifying same after many written requests. Customer would like to submit a detailed letter and safety inspection report with further info and details in addition to this online form complaint as this is a complex case and additional info will further prove up these allegations. Some documents provided by Rocky Mountain are inconsistent with customer complaints and do not reflect accurate info.

May 7, 2026 National Highway Traffic Safety Administration 1200 New Jersey Avenue SE Washington, DC 20590 RE: Safety Defect Complaint – Brake System / Vehicle Control Concerns 2020 Chevrolet Malibu Dear NHTSA, I am submitting a safety complaint regarding persistent braking and vehicle control issues involving my 2020 Chevrolet Malibu. Prior to December 31, 2025, the vehicle exhibited jerking during braking, all dashboard gauges go to the left, warning lights, reduced power (20-25mph), and inconsistent braking behavior. This situation happens without warning, at any given time, even in the flow of traffic. An independent inspection indicated the brake system was in proper condition, suggesting a more complex underlying safety issue. The vehicle was taken to Reed-Lallier Chevrolet for diagnosis and remained there for approximately five months. During that time, I was not provided documentation confirming completion of a brake system diagnostic or a clear resolution path. Due to the extended delay without diagnosis, I no longer feel safe operating the vehicle. I am also concerned that prolonged inactivity without proper repair may have worsened the condition and increased risk of failure. Given the nature of the symptoms involving braking and vehicle control, I request review for potential safety-related investigation. Vehicle Information: 2020 Chevrolet Malibu VIN: Mileage:

The contact owns a 2025 Chevrolet Equinox. The contact stated that while driving at 70 MPH, the vehicle unexpectedly decelerated to 10 MPH with no warning lights illuminated. The contact was able to restart the vehicle following the failure. The vehicle was taken to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 5,700.

My airbag light came on. My vehicle has less than 100K miles on it. I took it to the Chevy Dealership that I purchased it from. The dealership indicated that the passenger side rail air bag is the issue. Apparently, that airbag is no longer available. If I wanted to repair it, they can't, because there is no airbag. As long as the airbag light remains on, NONE of my airbags will deploy. My car is now a useless lemon. I don't feel comfortable driving it in the condition it's in, but I have to commute to work.

The check engine light came on with a warning that said "Steering assist reduced drive with care". The temperature gauge went to cold and the air condition quit working.

I was trying to stop at a light and the brakes wouldn't work. I almost crashed into the car in front of me but I had to step on it really hard to stop. Then the brakes were stiff and it was hard to stop. I brought it to a Chevy dealer yesterday and they said the vacuum pump exploded and pieces were in the engine, and it messed up the cam shaft. This is 5l worth of damage. When I looked it up online it seems this has been an issue with GM cars and the equinox was left out of the recall which could have prevented this. I have 95k miles on this car and never had an issue until now. However it is not worth spending 5k on a car that is high in mileage.

The contact owns a 2022 Chevrolet Silverado. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly hard shifted and the check engine warning light along with the reduced engine power warning light illuminated. The vehicle was taken to the dealer where it was diagnosed with trouble codes P0700, indicating a transmission control module (TCM) failure, and P2717, indicating a pressure control solenoid failure. The contact was informed that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA hotline for further assistance. The failure mileage was approximately 120,000.
