2021 BMW X7 Brakes

When starting the vehicle and shifting into drive, "hard" brakes are felt. Brake pedal is "stuck" in a high position and cannot be compressed. The vehicle is extremely unstable - the car lurches forward when brakes are slightly released. Excessive brake pressure is required to prevent the vehicle from moving inadvertently. This persists for 10-60 seconds, then the brakes relax into the normal position and no other issues are experienced. Confirmed NO lights on dash or warnings sounded. This has been experienced 4 times in 6 months. Issue has been reported to dealership. After second occurrence, dealership took vehicle for diagnostics and updated software. After third occurrence, dealership took vehicle and replaced ABS module, with software update. Feedback from BMW is that they think a diagnostic is running at startup and when the vehicle is shifted into drive it is not finished with the cycle. Most recent visit to dealership was late November 2022. Issue occurred again on 12/8 in the afternoon. Vehicle was parked in carpool line at school. When line began moving, vehicle was started and shifted into gear. Hard brake immediately felt (this is after repairs from BMW). This recurrence prompted this submission.

When applying brakes and releasing the brakes there is a grinding sound. The grinding sound is pronounced when applying the brake and turning the steering wheel at the same time. When I took the vehicle to Checkered flag BMW of Virginia Beach, I was told per BMW engineering it was norm operating characteristic. The Shop Foreman said he had several customers complain about the same problem and duplicated the problem while driving my vehicle. He was the person that showed me the noise was much louder when turning the steering while braking. The report I received from the Service manager named the issue as brake/pad rotor stiction and pad vibration. The invoice stated that the loud noise was not a flaw or defect, but normal operating characteristic. Simply put and 85,000 vehicle grinding noise is okay. I believe there is a problem that will get much worse over time and become a very serious safety issue. So much so that I will take a loss and sell the vehicle.
