Front brake vibration, alarming grinding/rubbing/screeching sound each and every time service brakes are applied. Dealer claims this is a known GM problem with no fix available. I have purchased two Cadillacs Xt6 and Xt5 May 2021. Both vehicles have the same problem. Wife will not drive the new Cadillac. Service bulletin published sbout this same problem, December 2020. Still no resolution, June 2021.

May 2021

The Sunroof popped and shattered. I was on the highway with very light traffic - cars were at least 200 feet apart - when I heard a loud boom and then felt and saw the sunroof cover start vibrating. It was not the small smack of a rock - it was a loud pop and I wondered if my muffler had just fallen off the car. But when the sunroof started vibrating I knew that my sunroof was gone.
