Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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“My car, which as of today, July 6, 2024 has a mileage of 45349, and is experiencing issues related to the EVAP purge pump under speed. I see that there is already been a recall on multiple models of the Chevrolet tracks, but not mine as it is a 2021 and not a 2020. I have owned this vehicle for two months, and have kept up with all of the maintenance as instructed. But I figured that this malfunction will lead to further damage, including but not limited to blown head gasket or blown engine.”
NHTSA complaint #11599593, filed 2024-07“1/23/25 This is the 3rd time the turbocharger has malfunction within 2 1/2 months and is once again at the dealership service department. Horrible smoke was filling the inside of the car while I was driving and smelled as though something was badly burning. The car had began shaking with minimal driving and loss of power. Electric dashboard not working which should indicate if there is any particular problems going on with my Trax. This is a real Safety Hazard. My car should be recalled in order to fix this hazardous problem once and for all!”
