2024 Chevrolet Trax

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.

The instrument cluster and center console display intermittently appears to lose power, although in at least one incidence, the back-up camera display still worked while in reverse. Without instruments it is impossible to determine speed which can be hazardous. The vehicle is scheduled to be looked over by the dealer on 8/21/26. To my knowledge, there have not been any symptoms or warning signs prior to any of the incidents where a power loss occurred.

Headlight Issue While driving at night on a dark country road the headlights all of a sudden reduced visibility to about 5 feet and had a blacked out dead spot (like a dark shelf). We had to drive roughly 25 miles with this limited visibility which was extremely dangerous and nerve racking. The visibility range improved the next day but the dead spot (shelf) is still visible and visibility is still poor and limited to about 100 feet. This still makes night driving very difficult and dangerous. I contacted dealership regarding issue and all they did was raised the headlights 3 inches. This only raised the dead spot up a little bit but is still visible. I notified them a second time and no action was taken because there was no recall for this issue on vehicle.In 2022 models there was a recall for the exact same issue.

The check engine light illuminated on my 2024 Chevrolet Trax at 36,883 miles. An authorized Chevrolet dealer, Advantage Chevrolet of Bridgeview in Bridgeview, Illinois, diagnosed a failed evaporative emission canister purge pump and replaced it on August 6, 2026. I paid $729.46 out of pocket. I am filing this complaint because General Motors has already identified this exact part as defective and extended warranty coverage for it — but not for my model year. The part installed in my vehicle, shown on my invoice, is GM part number 25207556. That part number is listed by name in the Parts Information table of GM Special Coverage bulletin N242484740, which identifies four interchangeable evaporative emissions canister purge pumps: 12741165, 12741163, 25207556, and 12726033. That bulletin extends coverage on this component to 15 years or 150,000 miles for the 2022 Chevrolet Trax, 2022 Silverado 1500, 2022-2023 Blazer, and multiple Buick, Cadillac, and GMC models. A prior program covered 2020-2021 vehicles. My 2024 Trax failed with the same part number GM covers for fifteen years on the 2022 Trax. The failure occurred at 36,883 miles — five days after my 3-year bumper-to-bumper warranty expired on August 1, 2026, based on an in-service date of August 1, 2023. The failure illuminates the malfunction indicator lamp, which masks any other diagnostic trouble code that may set behind it, increases evaporative hydrocarbon emissions, and causes automatic failure of Illinois OBD-based emissions inspection. GM has now issued purge pump coverage extensions twice, for 2020-2021 and again for 2022-2023 vehicles. The same component is failing on 2024 vehicles at comparable mileage. I believe the defect extends to the 2024 and later model years and that coverage should be extended accordingly.

I was at a complete stop with my foot all the way down on my brake, sitting in traffic, and my car started rolling forward against my will. I pressed down on my brake again and the car did not stop. I almost rolled into the car in front of me. The forward collision warning did not sound. I put my car in park and it still did not stop. I then put it into reverse to avoid rolling into the car in front of me. The car stopped. I put it back in drive, and the car jolted forward and the brakes continued to work. I have since taken it in and the master cylinder was failing. My brakes were only working sometimes. I am incredibly lucky that this happened when my car was stopped and not at a high speed, on the freeway, or in an area where I could have accidentally hit a pedestrian. At the time of the incident, no lights have every been/were lit up on the dash alerting me to an issue or failure with the car. The problem was confirmed and reproduced at the dealership. The master cylinder has been replaced and the brake system update has been completed. I want to reiterate how incredibly ridiculous and dangerous this could have been. It is unacceptable that this is not a formal recall as I have been notified that there is general knowledge of this problem. I have 2 small children that were in the car with me and this could have ended very differently had the conditions been different.
