NHTSA Complaint #11612358 — 2024 BUICK ENVISTA

While sitting at a stoplight, my vehicle began chiming along with the following symbols illuminated on the dash: Brake System Warning Light, Antilock Brake System (ABS), Malfunction Indicator Lamp, Electronic Stability Control (ESC). I also received the following warning messages: "Brake System Failure Max Speed 62 mph," "Service Stabilitrak," & "Steering Assist Reduced." When the stoplight turned green, I accelerated at a low speed to get through the intersection so I could safely pull over. When I hit the brakes, I had to jam the brake pedal as far as it would go repeatedly to get the vehicle to stop rolling and eventually stop. It felt as though my brakes went out, and every time I pressed the brake pedal it made a weird popping/air sound inside of the vehicle. I cautiously drove my vehicle at 5-10mph, 4 miles to my sister's home, and every stop sign/stopped car or stoplight I encountered I had to start braking 1/2 a block before because my vehicle didn't feel like it was going to stop. I called the service department at the dealership where I purchased the car 1.5 weeks before, and they provided me with GM's roadside assistance contact to have my car towed. My car was towed to the dealer, 45 miles away that night, and Thursday, 8/29, morning, the service department called me and said that they couldn't find anything wrong with my car - all of the warning lights and messages were no longer on, and the brakes were working as normal. Today is 9/3, and my vehicle is still at the service department as they try to get it to mimic what happened to me on 8/28.
