2024 Chevrolet Trax

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.

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.

WE HAVE NOTICED THAT THE CHECK ENGINE DOES NOT ILLUMINATE WHEN STARTING OR EVEN WITH ACTIVE CODES IN VEHICLE HAVE BROUGHT THIS TO THE DEALERS ATTENTION SEVERAL TIME TO NOT BE ACKNOWLEGDED THE REAR BRAKES LOCK UP WHEN YOU TOUCH THE BRAKE PEDAL HAVE BROUGHT THIS UP SEVERAL TIME TO NOT BE ADDRESSED THE VEHICLE WHEN DRIVING AT SPEEDS GREATER THAT 55 MPH THE VEHICLE GOES SIDEWAYS AND SCARES YOU HAVE BROUGHT UP SEVERAL TIMES TO NOT BE ADDRESSED THE FORWARD COLLISION DOES NOT WORK THE VEHICLE HAS ACTIVE CODES AND THE CHECK ENGINE SHOULD ILLUMINATE AND WHEN TAKE IN FOR SERVICE WE ASK WHY AND ARE JUST IGNORED ALL THESE PROBLEMS STARTED 2 DAYS AFTER BUYING THE VEHICLE IN SEPTEMBER OF 2023. iN ADDITION TO THE TRANSMISSION LEAKING, WAS TOLD HOWEVER THAT IT IS NOT A BIG ENOUGH ISSUE TO BE COVERED UNDER WARRENTY. THESE HAVE ALL BEEN ADDRESSED WITH DEALERSHIP AS WELL AS MANUFACTURER, AND AS OF TODAY 09/20/2025 THESE ISSUES HAVE NOT BEEN RESOLVED

My wife was driving to work and a car cut in front of her stopped for some weird reason on a green light and with the automatic braking the car stopped and was driving 20mph to 0 mph this was not i deal for the emergency braking and this should slow your car but not violently brake my daughter could have been seriously hurt thank god I have a good car seat

The affected component is the design of the cruise control engagement button, and yes it is available for inspection. While the vehicle is below a certain (unknown) speed, if the cruise control engagement button is pressed, the cruse control engages at a relatively high rate of speed, and the vehicle lurches forward. This is especially problematic due to the design of the switch, which is a protruded lever-type mechanism that is easily swiped while the steering wheel turns. Due to this design, a significant risk is posed for injury and fatal accidents. I have had several instances where this has occurred and I was forced to react quickly to avoid an accident. And I've only owned the vehicle for 9 months. This problem seems to be inherent in the design, and is likely reproducible on any 2024 Chevy Trax, and perhaps other Chevy models with the same design. This vehicle has never been inspected. There are no warning lamps or other symptoms, besides the design of the cruise control system. This has happened since I bought the car brand new from the dealership.

When driving 70+ mph on a county highway a dog ran out in front of my vehicle. There had been a similar instance to this where a car pulled out in front of me on the same road and my car assisted in making a full stop to avoid the accident. However, this did not happen with the dog. There was full impact damage and vehicle has been in the shop for 3+ months awaiting parts for repair.

The contact owns a 2024 Chevrolet Trax. The contact stated that the instrument cluster was flickering. The contact stated that the Forward Collision Avoidance system engaged without any objects nearby. While at a stop, the automatic STOP/START feature became inoperable. The vehicle was turned off with the key outside the vehicle, but the radio failed to turn off. Additionally, there was a lot of static on the radio. The steering wheel buttons were inoperable. The contact stated that the steering wheel was extremely hot. The high-beam headlights failed to engage while driving. The Back Over Prevention view was distorted and the touch screen was inoperable. The contact called the local dealer, where the system was rebooted, and the radio and camera were replaced. The vehicle was repaired, but the failure recurred. While reversing from the garage and then shifting to park, the key was removed from the ignition, and the seat belt alarm continued to ring. The vehicle was shifted to drive but failed to move forward. While exiting the vehicle, the vehicle failed to lock with the fob or manually. The manufacturer was contacted and opened a case. The failure mileage was approximately 1,000.

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).
