NHTSA Complaint #11717127 — 2021 CHEVROLET TRAX

The Turbo Charger failed suddenly without a prior display of a warning light and was replaced by an independent service center in June 2025. I received a letter from GM in November 2025 stating there was a known "condition" that may cause the Turbo Charger to need replacing but a recall was not issued. On 1/22/26 the vehicle suddenly went into "Limp Mode" while driving. The Throttle Body Injection Unit, Engine Coolant Water Outlet, and Coolant were replaced. The coolant had been topped off on 1/20/26. On 1/27/26 the vehicle began shuddering and lost power while I was driving on the highway. As I attempted to get to a gas station off of the next exit, it intermittently lost power and began smoking under the hood. It seemed to be overheating but there is no temperature gauge on the display. I had it towed to my service center again. At that time, four spark plugs and an ignition coil were replaced. After these repairs, I have continued to have significant power issues, the engine warning light has come back on, and the "Service Brake Assist" warning light has come on. Additionally, the instrument panel frequently goes blank or displays what can best be described as "static" and the A/C and heat do not work, making it difficult to defrost and defog the windshield. The wiper fluid will not come out even though the reservoir is full. Due to prohibitive diagnostic fees at the dealership, which I was told would not be waived or reimbursed, I have continued to utilize my independent service center to maintain basic drivability. My service center has advised me that the engine may fail completely within a short time frame. I have reported these issues to the manufacturer and have been assigned a case number. I'm concerned that this may indicate a potential safety defect and/or premature engine failure affecting my vehicle and others of the same model. I'm submitting this complaint for documentation and safety tacking.
