Brakes are squealing when in reverse. After the vehicle has not been driven for a day or even parked for more than an hour. Placing the vehicle in reverse, when backing out of the carport and turning the steering wheel to the left, there is a bad brake squeal. Had the same issue on my 2024 Toyota Tundra. That was fixed under T-SB-0043-24. The 2022-2024 Lexus GX550 has the same issue and has had a Service Bulletin issued L-SB-0036-24. The GX550 and Toyota Landcruiser use the same brakes. Dealership will do nothing till a SB is issued.
