2024 Chevrolet Trax 1RS, approximately 66,000 miles. I was driving on the interstate at approximately 77 mph when I suddenly heard a very loud bang from the engine area. Immediately afterward, the vehicle began smoking both inside and outside, and there was a large black cloud of smoke behind the vehicle. The engine stalled and I lost propulsion while traveling at highway speed. I was able to move the vehicle to the side of the interstate. The vehicle then displayed a warning stating, “Oil pressure low, turn car off immediately.” I shut the vehicle off and did not continue driving. The vehicle had to be towed to an authorized Chevrolet dealership. The Chevrolet repair order dated August 10, 2026 documents the concern as a loud engine noise and notes that the tow/wrecker driver reported a hole in the engine block. Chevrolet’s inspection marked the engine oil, fluid leaks, and cooling system as “Alert.” At the same inspection, the engine oil-life monitor showed 93%. Chevrolet recommended removal and replacement of the engine long block. The dealer estimate lists $11,106.14 for the long-block replacement and approximately $13,420.89 in total pending recommendations. GM has agreed to provide partial financial assistance toward the engine replacement, leaving me responsible for approximately $5,200. The replacement engine is currently on backorder, and the vehicle remains inoperable while awaiting an engine. I am filing this complaint because the engine failed suddenly while I was traveling approximately 77 mph on an interstate. The loud mechanical failure, smoke, engine stall, and sudden loss of propulsion created a serious safety risk. I am concerned that this may be related to similar engine failures being reported in Chevrolet vehicles equipped with the 1.2L turbocharged engine. I have retained the Chevrolet inspection report, repair estimate, photographs of the engine following the failure, GM case information, and documentation concerning the replacement.

My 2024 Chevrolet Trax is currently operating with a suspected internal engine defect tied to active Safety Recall A242435780. On 7/27/2026, Michael Hohl Chevrolet performed the software patch for this recall. However, severe internal engine noise remains. On my official repair order, the Shop Foreman test-drove the vehicle and explicitly documented: 'suspects could be something internal will need further diagnostics. Despite this documented internal engine concern tied to a federal safety recall, GM Corporate (Case #[XXX] (tel:[XXX])) and the dealership refuse to cover the diagnostic engine teardown. GM Customer Assistance formally told me to stop driving if the noise worsens, shifting the safety liability to me while refusing to remedy the defect. A sudden internal engine failure while driving will result in an immediate loss of motive power, power steering, and braking assistance, creating a severe crash hazard.

We were driving on the highway when the Trax suddenly made a popping sound, all the electric went off, and then the engine cut off. We lost control of steering for a bit, we're able to get to the side of the road. We had the car towed to the local Chevrolet dealer for diagnostics. The service manager informed me the engine is unrepairable due to a hole in the engine block, likely where the engine threw a rod. In order to get the engine replaced we have to have it towed to a second dealership, which we are in the process of doing now. I just purchased this vehicle 3 weeks ago without knowing this issue was a possibility

Vehicle engine light came on XXX and was driven immediately to Auto Zone to check the code. The code showed P0299. The vehicle was then taken 2 miles home and parked. It was towed to Lake Chevrolet in [XXX] on XXX to prevent any engine damage from occurring due to the failed turbo. Upon Lake's inspection they claim the manifold and valve cover gasket must be replaced. We agreed to that, and asked about an oil change as everything we read said that was mandatory with work like this. Was told the technician didn't suggest it but they would do it at our request for an additional charge. After they confirmed the turbo was bad and well as the items above we agreed to the repairs and they said the vehicle would be ready the next day. We called again at the end of the next day and they said the repairs were made and they were going to drive the vehicle to make sure all was well. The next call we received was the service advisor stating we need a new engine as after they drove it white smoke was coming from the exhaust and they now found a cracked piston. The vehicle was not blowing out white smoke when they received, it also passed emissions on 4/14/26. We also asked for all technician notes, diagnostics, etc. which they will not provide us unless we come in and get the non running vehicle and pay the 983.00 invoice. We would have to have the vehicle towed from their lot as it can't be driven since their repairs. We contacted GM and spoke with "Tamar" multiple times with no resolution. Service manager claims GM will pay 1,500.00 towards a 9,000.00 new engine. This engine damage is consequential damage of the turbo failure which the dealership is denying. GM and Lake Chevrolet are refusing to honor special coverage XXX for the resulting catastrophic damage. Dealership also refusing to provide documentation requested in attached letter. We seem to be expected to take their word for all of this. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

My engine failed with no warning on my 2024 Chevy Trax , at night in the express lanes of a very busy expressway in Chicago. I was able to get on an off ramp, but the car then stalled again and I was almost hit by other vehicles trying to exit the ramp. I did call 911 and was told to stay in my car because I would have a "better chance of survival". I had just had the car at the dealership for an oil change and check-up a few weeks before. The dealer explanation was the engine is defective and they replaced the engine, but I have no confidence in this car. I told the dealer and they did not seem to care. I have had nothing but problems with this car, it is a danger to myself and others driving this car.
