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.

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.

To Whom It May Concern, I am submitting this formal complaint regarding a malfunction in the air conditioning system of my 2024 Chevrolet Trax. Specifically, the evaporator and/or condenser has failed, resulting in inadequate cooling performance and potential system leakage. This issue is more than a matter of comfort—it presents a significant safety concern. Operating the vehicle in high temperatures, particularly in Texas, creates hazardous conditions inside the cabin. Excessive heat can lead to driver fatigue, dehydration, and reduced concentration. Additionally, the malfunctioning A/C system affects humidity control, which may cause windshield fogging and reduced visibility while driving. The problem has been consistently reproducible during normal vehicle operation. Symptoms include poor cooling performance, inconsistent air temperature, and possible unusual odors or sounds when the A/C system is in use. Notably, no warning lights or dashboard messages appeared prior to the failure, making it difficult to detect the issue early. At this time, the vehicle is available for inspection and can be evaluated by a dealership, certified technician, or manufacturer representative upon request. I request a thorough inspection to confirm the failure and determine whether this is due to a manufacturing or design defect. If necessary, I am also willing to have the vehicle reviewed by independent service professionals or relevant authorities. Given that this issue has occurred in a nearly new vehicle, it raises concerns about reliability, quality control, and potential widespread defects affecting other vehicles of the same model. I urge prompt investigation and corrective action to ensure driver safety and product integrity. Please advise on the next steps for inspection, repair, and resolution of this matter. I appreciate your prompt attention to this serious issue. Sincerely, [XXX] [XXX] [XXX] 35300 Began@ 35,000 and progressed INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
