What owners report
emission warning light and verified by on star diagnostic. Carried to Rick Hendricksn Gm dealer in Buford Ga. for a 7 day diagnostic and repair. I also could smell gasoline when the car was running and smell gasoline inside my garage when the car was parked..very strong odor. Dealership found it was a EVAP system leak. removed and replaced the filler neck . My vehicle had 650 miles on it when I started getting warning notices that would come and go.
While driving on the interstate vehicle begin to surge and lag with a check engine light appearing. Vehicle never became disabled but after reading it sounds like this a very known issue with Trax's. Chevy app stated it was the emissions control system which is most common for purge valve failure. GM needs to issue a recall as the purges valve in every Trax is defective just like the did with earlier models.
My check engine light went on and stayed on while I was driving. I called Blaise Alexander, Altoona, Pa. reported and scheduled a checkup on Dec. 11. I drove to the garage, arriving at 10am. and noticed a smell of fire and saw smoke billowing out around the hood of the car. I ran into service area and told them the car must be on fire. They called the Altoona Fire Dept. The police gave me a number, which I gave State Farm Insurance. I drove approximately 23 miles along Rt I 99 to reach the garage. Apparently there is a history of 2024 and 2025 Trax models having fires in the engine. Possibly associated with the fuel system.
I just purchased this vehicle. I found that the fuel filler neck has a leak which is a fire risk. I was initially promised that the part would be replaced in a week, but recently found that the part is back ordered because this is a prevalent issue with 2025 models. At the dealer I was mislead into thinking this isn't a big issue when it is, I was told I could continue to drive the vehicle with minimal risk but gas has been leaking in my grass and causing it to change colors as well as paying more for gas despite being sold on great gas mileage. To make matters worse worse the vehicle is starting to sputter and has less than 2K miles. I feel that this should be a national recall before someone gets hurt. Chevy Trax are affordable for tons of people if all of us are in combustible vehicles the environment is bound to take a hit. Please help.
