When car has been unused for a period of time, the right rear brake makes noise when the car is moved. This happend in either forward or reverse. Even after driving for a short period of time, the noise is still evident. Under warrenty, I asked the dealership to resolve. They indicate this is an ongoing investigation by GM. I purchased the car new in July 2021. This problem has persisted since purchase. I have reported it multiple times to the dealer but they pass it off as GMs problem. In reviewing other similar complaints for the 2020 model, it was resolved by changing the brake pads to a different material. Surely GM can find a cure after 3 years since production.

Recently I have noticed that the back brakes squeak and sound like they are grinding when backing up. Also every now and then the information screen will go black for a while then turn back on could be a few seconds or several minutes. 23,900 on car
