NHTSA Complaint #11674084 — 2021 CHEVROLET SUBURBAN

My wife was driving the vehicle and was pulling into a parking lot. The brakes failed and would not stop the vehicle. She pressed on the brakes very hard, multiple times, for several seconds, before the vehicle finally came to stop. She then proceeded into a parking spot where the brakes again failed to stop the vehicle promptly. Several lights illuminated and a “System Brake Failure 43 MPH Top Speed” message appeared, alternating with several other messages appearing. The vehicle is in for service at Classic Chevrolet in Granbury, Texas. They are telling me that they reset the codes and that the codes are not returning. I am extremely concerned that if I pick up the vehicle at this point, the brakes could fail again and cause an accident with serious injury.
