The vehicle has 2 permanent codes. One is a communication blackout, the other code means the hardware is melting. GM is doing a formal inspection in April. The Ucode meant that the engine stopped talking to the transmission or visa versa. The vehicle “ran my daughter and I” off the highway into the dirt, on 2 different occasions. They are described as “catastrophic engine failures”. The last one occurred on MLK Jr Day 2026, before the vehicle was permanently grounded. It could have been fatal. GM is doing a formal investigation to see what liability the have for it because the vehicle is now considered a “lemon”. There were no external (dashboard) warnings before the events, but, there may have been internal ones that require a professional grade scanner to detect. The permanent Ucode, which causes a communication blackout, never appeared in the vehicles memory, on a scanner, until AFTER the local GM franchise conducted “repairs” (unsuccessfully) to fix the vehicle. (It wouldnt start, which is often a symptom of a Permanent UCode. The GM investigation will determine if the dealership knew the safety liability, (the permanent Ucode) and they tried bypassing or ignoring it, or, if they CAUSED the safety defect. Also, the vehicle is now showing a Permanent PCode, which means it is now a potential fire hazard.

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.

The contact owns a 2021 Chevrolet Trax. The contact stated that while driving 70 MPH, while the roads were clear, dry, and the weather was good, the engine seized, and the vehicle lost motive power and decelerated to 55 MPH. The contact pulled over to the side of the road, and the brake pedal was depressed; however, the vehicle failed to respond and continued driving forward. While driving at 50 MPH, the failure reoccurred. The engine and stabili-trak illuminated after the vehicle came to a complete stop. The local dealer was contacted regarding loaner vehicles on two occasions. The vehicle was not diagnosed or repaired. The vehicle was scanned, and DTC: TCM U0101 and P0700 were retrieved. The manufacturer was contacted, and the contact was referred to the local dealer and the NHTSA Hotline for assistance. The failure mileage was approximately 68,000.

At roughly 20,000 miles, my cars' carplay connection begain to intermittently disconnect. Never could get it to reproduce the same results when at the dealership. At roughly 60,000 miles the VCU (vehicle cockpit unit) began glitching. It would flicker, go black and then come back after a few seconds. Now at 92,xxx miles (don't know how many miles because it's black right now) its off more than its on. I can't get access to important vehicle information including digital speedometer, milage, tire pressure, oil life span, miles left until my gas tank is empty, and more. This makes it impossible to adhere to an oil change done at proper intervals, knowing my exact speed when driving, or if I'm about to run out of gas. And i cant see my tire pressure if it fluctuates before the tire pressure sensor goes off, possibly preventing me from getting to safety BEFORE i have a flat tire. GM has a recall for the screens on the newer 2024 and 2025 Trax, but this has been an issue in the Chevy Trax since around 2016. Also while driving in rain or wet conditions, the side detection shuts off and the screen will say "Side Detection System Unavailable" and no longer works. I have not been able to take my car to the dealership because they want too keep it and I don't have another way to get to work or get groceries. This car is my lifeline.
