Telematic Modular Control is not working properly and part is on backorder. Dealership and GMC have refused to put into writing that my vehicle is safe to drive; however, they are refusing rental vehicle while awaiting arrival of part. Several of my safety features are not working correctly, my left turn signal went out randomly and my auto breaking has activated when there has been nothing near my vehicle. Service brakes

Brake Master Cylinder failure. Received warning lights on the dash and took to the GMC dealer for the diagnosis. Dealer stated the car is not drivable because the brakes could fail. The head mechanic at the dealership confirmed that the cylinder is the problem. They had no idea as to how long it would take to find a replacement cylinder. Service brakes
