2024 Chevrolet Trax brake problems

SERVICE BRAKES

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.

SERVICE BRAKES

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.

An air duct above the brake pedal came loose from the heater and dropped down over the pedals. My wife said she could not get the car to stop at an intersection. The car rolled to a stop in the middle of the road and she could not get it to go as the accelerator was also blocked. A police officer pushed it off the road.

SERVICE BRAKES

I was driving at 50mph when I lost power to my brakes. The brakes still worked well enough to get home, but I had to slow down well in advance of every turn and push hard on the brakes. Warning lights saying Brake System Failure (43 MPH Top Speed), Service Stabilitrak, and Steering Assist is Reduced Drive with Care. This problem has been talked about by other owners on Forums on the internet. Here's one of the websites: [XXX] One of the guys on that forum said the dealership found it to be a faulty brake fluid level sensor. The car's lane assist did seem to act a bit weird a couple of days before the warning lights came on. I felt like the car was trying to reposition despite being in the middle of the lane. I will be bringing the car to the dealership in the near future. They haven't had a chance to look at it. I could see an inexperienced driver panicking if faced with the multitude of warning lights and loss of proper brake function. The car only has 350 miles on it.
