“The Turbo Charger failed suddenly without a prior display of a warning light and was replaced by an independent service center in June 2025.

“My wife was driving and we were hit hard enough to shove the vehicle into the next lane and crumple the undercarriage of the vehicle. Making it undrivable anymore. And any information I can find says side impact air bags will deploy if the vehicle is hit anywhere on the side of the vehicle. Which clearly did not happen in this case. A side note I can only ever find videos on direct side impact not indirect impacts that involves the wheels. In either case the front or back tire impacts will still involve the persons head being slammed into the door window causing head injury.”

“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.”

How we read this (methodology)

How to read this: raw complaint totals are not a clean reliability score — a model year with more cars sold, or simply more years on the road, accumulates more complaints regardless of how good it is. So this page leans on two signals that are not distorted by sales volume: the share of complaints falling on each vehicle system (the breakdown above) and NHTSA's own crash / fire / injury / death flags. When we compare model years of the same model, we normalise by years on the road (complaints ÷ vehicle age) rather than comparing raw totals. Age-normalised, the 2021 Chevrolet Trax draws about 3.8 complaints per year on the road, ranking 8 of 9 among the Chevrolet Trax model years we have ingested (1 = most complaints per year on road).
