Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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“The front exhaust flex pipe leaked by a corrosive hole that allowed exhaust and CO carbon monoxide to escape making the drivers dizzy, nauseated, and with a headache. This also caused the vehicle to smoke, run rough and stall in traffic. This also required the post 02 sensor to be replaced.”
NHTSA complaint #11654663, filed 2025-04“The vehicle is very hard to control in high winds. I was driving down the highway on a very windy day the vehicle fishtailed the entire time. Almost rolled the vehicle it’s very dangerous”
