My 2019 GMC Acadia has abruptly automatically braked while driving between 10- 15 mph and without any cars near the vehicle. It slams on the brake like it's the parking brake and makes a grinding noise. . This has occurred on 2 different occasions. After the 1st time the service parking brake light came on. The dealership said it was related to a faulty battery because I received an onstar notice about my battery. . It occurred again after having the battery replaced.
