Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“UNKNOWN I’ve had my car for 11 months. When I first got the car I got it fully inspected and there were minor issues like tires and brakes. However, now the ac compressor is completely damaged and there may be contamination in my lines. This is not an owner issue. I take really good care of my car. I just don’t know how this could’ve happened if this wasn’t a manufacturer related issue.”
NHTSA complaint #11669633, filed 2025-06“My car is only at around 37,7000 miles. My I have only had it since it was around 15,000 miles. My battery has died at least 4 times due to my alternator having problems charging. My brakes have also gone out on me at one point in the beginning. My battery is now trash and so is my alternator.”
NHTSA complaint #11603491, filed 2024-07“The vehicle has 2 permanent codes. One is a communication blackout, the other code means the hardware is melting. GM is doing a formal inspection in April. The Ucode meant that the engine stopped talking to the transmission or visa versa. The vehicle “ran my daughter and I” off the highway into the dirt, on 2 different occasions. They are described as “catastrophic engine failures”. The last one occurred on MLK Jr Day 2026, before the vehicle was permanently grounded. It could have been fatal. …”
NHTSA complaint #11725693, filed 2026-03“The Turbo Charger failed suddenly without a prior display of a warning light and was replaced by an independent service center in June 2025. I received a letter from GM in November 2025 stating there was a known condition that may cause the Turbo Charger to need replacing but a recall was not issued. On 1/22/26 the vehicle suddenly went into Limp Mode while driving. The Throttle Body Injection Unit, Engine Coolant Water Outlet, and Coolant were replaced. The coolant had been topped off on 1/20/26. On 1/27/26 the vehicle began shuddering and lost power while I was driving on the highway. …”
NHTSA complaint #11717127, filed 2026-02“The contact owns a 2021 Chevrolet Trax. The contact stated that while starting the vehicle and then driving at an undisclosed speed, the instrument cluster intermittently went blank. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,000.”
