There are 6 owner-reported electrical system complaints for the 2021 Chevrolet Traxin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
UNKNOWN I’ve had my car for 11 months. When I first got the car I got it fully inspected and there were minor issues like tires and brakes. However, now the ac compressor is completely damaged and there may be contamination in my lines. This is not an owner issue. I take really good care of my car. I just don’t know how this could’ve happened if this wasn’t a manufacturer related issue.
The instrument panel where the digital speed, tire pressure, mileage etc.. is displayed goes black. Sometimes it comes back on and sometimes it stays off for hours
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.
My car is only at around 37,7000 miles. My I have only had it since it was around 15,000 miles. My battery has died at least 4 times due to my alternator having problems charging. My brakes have also gone out on me at one point in the beginning. My battery is now trash and so is my alternator.
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.
