2024 Chevrolet Trax Powertrain & Transmission Problems

On 4 seperate occasions, my vehicle has completely shut off in the middle of the road. 3 times this has happened while traveling on the interstate. Every time with my 6 year old son in the car. The steering wheel locks up when it happens and you have to use all of your strength to get out of the road as soon as possible to avoid being smashed by oncoming traffic. On 8 seperate occasions, my vehicle randomly loses the majority of it's power, and takes over 6,000 rpms just to continue at 50mph. The issue fixes itself by the time I try to take it to the dealership and they tell me there is nothing they can do about any of these issues because it "isn't doing it now" - refusing to even look at it. If I don't take no for an answer, they said just a diagnostic will take 48 hours and they do not offer any sort of loaner vehicle. Both of these events happen without warning, at completely random times. Chevrolet service members each give me different advice and non of it is helpful. My car is a death trap. I bought it brand new with 5 miles on it. I had to order it and wait for it to be shipped to me. This has happened throughout the entire life of the vehicle.

I was driving down the highway going with the flow of traffic and my car caught fire. I was told by the mechanic that “the turbo line combusted and put a hole in the engine” I’ve also been told “oil got on the turbo belt and caught fire” I’ve also been told “the software recall actually had nothing to do with the software and it was an issue with turbos and something was mechanically wrong with this car. I was in the car with my 9 month old daughter. In the middle lane in the highway. The car instantly stopped accelerating leaving us going very slow compared to others. We could’ve been killed! I had to figure out how to get over and then get my daughter out of the car safely and wait on the side of the highway with a baby for fire and police to come put the fire out. When I was driving it sounded like pressure popped under the car and then I could almost hear pieces flying out. And then the dash lights came on telling me to turn the engine off. It was extremely unsafe and now I’m afraid to even drive with my baby in any car.

We have a 2024 Chevrolet Trax purchased in July 2024, brand new with 6 miles. On Jan 9, 2026, we towed it to Serra Chevrolet for service due to repetitive screen blackouts and the inability to start the car. On Jan 16, 2026, we picked up the car. The car was diagnosed with a radiator leak, a replacement of the high-pressure fuel pump, and an update to the information system. Within two hours, the car would not start again, and we had it towed back to the dealer. We have been told that it now requires an entirely new engine, and we have been renting a car since January 9th, with no reasonable solutions from the dealer or GM Customer Care. We have also been informed that the engine is on backorder, and we have no timeline for its repair.

On December 28, 2025, while driving normally with my children, my 2024 Chevrolet Trax displayed multiple warnings including Engine Power Reduced, Service ESC, Service Stability, and Steering Assist Reduced. The engine began sputtering and knocking. The next morning the vehicle would not start and was towed to Malcolm Cunningham Chevrolet. The dealership found the engine free-wheeling with no compression and denied my warranty claim alleging spark plug tampering. I never touched the engine. It went directly from my driveway to the dealership via tow. An active recall — A242435780, Engine Spark Timing Following Auto Stop Event — was noted on the repair order upon arrival but was not completed until February 17, 2026, seven weeks after the engine failed. GM’s own recall states engine knock and engine damage are the known risks of this unrepaired fault. The dealership told me verbally it was just a console update, directly contradicting GM’s published description. A second dealership performed a compression test showing Cylinder 1 at 10 PSI, Cylinder 2 at 90 PSI, and Cylinder 3 at 0 PSI. Normal compression is 150 to 200 PSI. No diagnostic codes were retrievable. This dealership initially found something different but reversed their position after speaking with the first dealership and receiving direction from GM. GM denied my warranty claim and offered only a 2,000 incentive toward a new vehicle. The vehicle remains completely unrepaired. I continue making monthly payments on a car I cannot drive. This aligns with class action Cook v. General Motors LLC, Case 1:26-cv-00229-RGA, filed March 4, 2026.

For the past 3 to 6 months I've been hearing a gear backlash sound while using the adaptive cruise control when it would slow down for a car in front of the vehicle then when it would start to speed up. Brought the vehicle to the dealership on October 20th, 2025. They said that the sound is normal and there's a service bulletin that says its normal in other Chevy models. Then on November 28th, 2025 I was driving home, turn right at a light, and started to accelerate. Then I heard the same backlash noise as before then the check engine light came on with the oil light. I pulled over immediately and turned off the engine just to see all the oil spilling out of the engine compartment onto the ground and white smoke. Got it towed to the dealership and they told me that "the engine had multiple components fail inside it and that I need a new engine assembly." Currently the engine is still in the vehicle awaiting a new engine assembly what is currently on backorder with no expected arrival time.

Brake System malfunctioned. Brakes making horrible grinding noise at 25000 miles. Took to dealership under warranty and was told "that is just the sound that GM brakes make" and they refused warranty repair. Assured noise wouldnt worse, but continued. Paid to have brakes replaced and the SAME exact noise continues today. Brake fluid leaked everywhere and totally disabled the entire braking system while driving on the interstate. When the brakes went out, i loss power and it was difficult to steer. Tried receiving assistance from Chevrolet on many occasions until i gave up Car flashed a message suggesting vehicle was experiencing loss of power while driving down interstate, cleared the message and vehicle power remains weak. Code suggested turbo was going out. Car honks 2-3-4 times while in park only 5 minutes. Oil has to be changed constantly. Last oil change took 2 weeks before now having only 81% oil life. Forward collision warning warns when nothing is in front or around you. Lane keeping assistance cuts in and out and doesn't always work. Backup camera shows upside down often, and distorted. ECM warranty reset has been completed. Lane departure warning signals hazard where there is none and sometimes lane keeping assistance disallows me to remain in the middle of my lane so i have to cut it off. interior and exterior lights and radio have remained on for hours after locking vehicle and going inside my house.

The manufacturer was notified of the failure, and the contact was referred to the dealer for assistance. The vehicle was not repaired. The failure mileage was approximately 1,900.

My car sometimes has a hard time catching a gear during acceleration and jerks hard when letting off the gas pedal. It has done it since I purchased my car brand new in November 2023. I've had the car in the shop numerous times since I've purchased it. For a variety of issues.

Going at speeds 60-70, transmission slips and is jerky, pulsating symptoms. Unsure if transmission slipping or brake malfunction. Going at speeds lower, very hard gear shifts. Using adaptive cruise control at speeds 60-70, car slammed on brakes for no apparent reason and remained using the break, would let off (clear and wide open in front of me).

The contact owns a 2024 Chevrolet Trax. The contact stated that while driving approximately 60-72 MPH, with the cruise control activated or turned off, the contact detected an intermittent pulsation. The contact stated it was like the brakes had engaged or the transmission was slipping. There were no warning lights illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 579.
