BACK OVER PREVENTION: WARNINGS
1. Vehicle has a horrible squeaking sound coming from the brake pedal area. First dealer diagnosed it as the master cylinder needing replacement. Noise did not go away and GM said that it is normal. The noise is not normal and has never been on any other car I have owned. 2. When reversing, the car sometimes abruptly slams on the brakes as if it is avoiding a collision even though no collision is close to happening. GM refuses to fix the problem.

FORWARD COLLISION AVOIDANCE: WARNINGS
Multiple safety-critical malfunctions have occurred on this vehicle involving unintended braking, unintended acceleration, and false activation of driver-assist systems. These events did not happen at the same time and occurred under normal driving conditions. At various points, the vehicle has suddenly applied the brakes without driver input, including hard braking events that felt like an automatic emergency braking activation when no hazard was present. In separate incidents, the parking brake has engaged while the vehicle was in motion, causing abrupt deceleration. There have also been instances of unintended acceleration where the vehicle surged forward briefly without additional throttle input. These malfunctions appear to be related to electrical or ADAS system faults affecting braking logic and propulsion control. No warning lamps or messages reliably appeared before these events. The issues pose a serious risk to the safety of the driver and others because the vehicle’s behavior is unpredictable and can interfere with safe control. The dealership was unable to reproduce the conditions during inspection, but the incidents have occurred multiple times in real-world use.
