Description of the problem | While traveling straight at 70 mph on the highway in my 2015 chevy suburban (62k miles) the vehicle experienced a sudden and undetected complete brake system failure. As i approached slowing traffic with the cruise control on, i tapped the brakes to disengage the cruise control, only to find that the brake pedal was rigid and could not be depressed. To avoid a collision at a high rate of speed i swerved onto the right shoulder while using two legs to aggressively push the brake pedal down - all the while feeling very little braking action. The car came to a stop after about 75 meters. At no time before or during the event did the car signal a braking system problem. In fact it still showed no system indicator of a brake problem 3 days later when it was delivered to the dealer for diagnosis. The car has been well maintained, having just undergone a 60k mile service at the dealership. The lack of the vehicle's recognition that a critical failure in the braking system had occurred posed a serious and immediate threat to passengers and surrounding traffic. As a physician i can attest that a collision at that speed would have severely injured or even killed those involved. This problem with the 2015 chevy sub has reported to nhtsa before - this is not an isolated event. The service center reported to me that a vacuum pump failure was to blame - i believe this is a more complex engineering problem in that the vehicle did not detect a problem despite the failure creating a life threatening scenario. Although i plan to immediately dispose of this car, failure to address this problem by the manufacturer will put others at risk in the future. Gm appears to have issued a service bulletin that refers to this problem (attached). I sincerely believe this defect will result in lives lost if left unaddressed.
