As I first started the vehicle with the brake pedal depressed and the transmission in Park, I heard and felt a grinding similar to what would be heard and felt when the ABS is activated when braking on a slippery surface such as snow or ice. At that point, the "Service Brake Assist" message was displayed in the center of the instrument cluster. I cleared the message to let the vehicle move. Every time that I depressed the brake pedal, the same thing would happen -- grinding similar to what would be heard and felt when the ABS being activated (in between each instance, I would clear the message from the screen). It did not matter if I was going 2 mph or 20 mph, going forward or backwards. I drove up to 25 mph and this also resulted in diminished brake performance - which could put others at risk. In this regard, I do have two videos of the incident. When I shut the car off and opened the driver's door, the Suburban reset and the brake assist system operated normally for the rest of the quarter-mile drive back to its parking spot as though nothing had happened. The vehicle is currently at the dealer for repair. It is important to note that this same issue occurred approximately one year ago and the dealership advised that they had replaced the brake booster sensor at that time. Please reference NHTSA ID Number 11384064.

Sep 26, 2018

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."

Consequence & remedy

Consequence: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.

Remedy: GM will notify owners, and dealers will inspect the rear seatbelt retractors and replace them if necessary, free of charge. The recall began November 7, 2018.
