Adaptive Cruise Control Problems of Chevrolet Bolt Ev

The brake pedal can easily become disconnected from the electronic brake booster behind the firewall. When this happens, it stops all driver aids. The safety issue is it can happen while driving, and if using adaptive cruise control, or gm super cruise, if one pedal driving is on, it can without warning substantially slow the car, and has the potential to cause an accident. Its not too far to think the dislodging can cause the boost arm to be placed in a position to prevent full brakeing either. I have not taken it in because it is a design flaw of the system I believe. From searching online, I found the assembly, and it lacks a locking pin in the pedal to the shaft as you can see in the service diagram attached. Speaking to someone at a gm dealer they verified the issue on another 2027 chevy bolt, but not reproducible on other gm vehicles with the same electronic brake boosting system.

The contact owns a 2027 Chevrolet Bolt Ev. The contact stated that while driving approximately 65 mph with the adaptive cruise control activated, the braking system suddenly activated causing the vehicle to abruptly decelerate when another vehicle passed by. The contact stated that the failure had occurred on two separate occasions while being overtaken by another vehicle on the passenger’s and driver’s sides. The vehicle was taken to the local dealer to be inspected; however, no cause for the failure was found. The manufacturer was notified of the failure. The failure mileage was 900.

Not necessarily a failure or malfunction. When making right/left turns vehicle will accelerate for apparently no reason. Each time entering a parking lot or making a standard right/left turn. Each time this has happened during this acceleration it has almost caused a vehicle crash with another car in front or in another incident almost hit pedestrian. Found that the rocker switch for cruise control is being hit accidentally causing cruise control to become activated causing the vehicle to accelerate.

The system in question is the super cruise hands free driving system. There has been several instances where the system has swerved the vehicle without warning or reason. There have been several instances where the system has failed on mapped road. There have been several instances where the vehicle wouldn't drive in the center of the lane, but instead on the lines or too close to other vehicles. I have dash cam footage and cell phone footage of the system failing and can duplicate it without issue. The vehicle spent over 30 days at the dealer and they were unable to fix it. The message that will appear when the system intermittently won't activate is "super cruise unavailable" I have attempted to work with my dealer, gm, and onstar and nothing has been done to take my safety seriously or to fix the issue.
