Just picked up my truck, Dealer replaced Brake Master Cylinder, Power Brake Booster, and Brake Control Module. I remote started the vehicle at the dealership with the MyChevrolet App successfully so time will tell. I called GM and opened a case in addition to requested an address to send a certified complaint and the representative I was speaking to would not relinquish the address he kept stating "A Service Manager will reach out to you in 2-3 days" I eventually got an address from him... This is ridiculous...
