Brake Sensor problems of the 2019 Chevrolet Traverse

There are continuous defects and concern for safety regarding my 2019 chevy Traverse. I purchased a new 2019 Traverse redline on March 22, 2019 and the problems began within two weeks and less than 400 miles on the vehicle. I was driving my new vehicle on a residential road and began to slowly press the brake while approaching a stop sign when the �service brake assist� alert appeared, the brakes made a grinding and clicking noise while shaking and felt like the brake pedal needed to be pushed all the way to the floor to stop. I brought the car in and the service department replaced a vacuum booster sensor which they said was faulty. Then two months later, with only 1800 miles on the vehicle, the same issue occurred again where the �service brake assist� alert appeared, the brakes made the same noises and shaking. I immediately called the dealership to bring it in for service. During this second occurrence, the service department suggested it must have been a �bad batch� of parts and offered to replace the sensor again. I returned to the dealership to pick up my vehicle and during the less than two mile drive home, the same issue occurred for the third time. I immediately returned to the dealership again and the service department said they didn't know what was causing the problem. After replacing the same part for a third time, the same issue occurred again. Ultimately, the service technicians & engineer are unable to identify the root cause of the issue and merely suggested replacing the same part for the fourth time. While the service manager has offered to continually replace the same parts, they also are unable to identify the root cause and stated I need to continue driving the vehicle until it happens again and perhaps there will be a new part updated in the future.
