“Within two days of getting the car with 7 miles on it, as soon as I got over one hundred miles, the car texted me and said that I need to get the emissions serviced on the vehicle. Last time I went through this with kia... They fixed it twice and then my engine pretty much died and they blamed me (on a 7 year old car)”

The service manager at ron westpahl, david, said there is a service bulletin out for the ifor this problem, it is a known problem in the north with the cold weather the inverter get condensation in the vehicle and freezes.

NHTSA complaint #11398458, filed 2021-03, 30,000 miles“I was driving my car and was at a stop sign and the vehicle started acting odd and it felt like it was lunging me forward. I was concerned that it was going to do it without my control and after that it almost sluggish and stalling until I could get it out of the intersection. Took it to a repair shop and the whole turbo unit needs to be replaced with 38,000 miles on it.”
NHTSA complaint #11719156, filed 2026-02“When putting shell premium gas I noticed my cars Rmps is way lower than usually and my acceleration is a lot slower/delayed I never had this problem when I put regular and midgrade (plus) gas furthermore I noticed I got a weird B3935 error check code but I don’t think that’s related to the gas though”
NHTSA complaint #11677872, filed 2025-08“Radiator, ta 80k Miles the seal broke and causing a coolant leak, upon looking at forums related to my car there are NUMEROUS complaints, my safety was at risk because my car could've overheated and shutdown when traveling and caused a major accident. The Trax is known for this issue, yet no recalls or anything. There was no accident associated with this but I am truly hoping someone gets ahold of Chevy/GM about this issue”
