I would like to share something that happened today. I parked my x by backing the rear end towards a wall. the car gave its customary warning beeps and the radar showed how many inch of clearance I had. I have done this thousands of times without any issue or bumping into anything. Unfortunately, on this particular wall, there is a metal pipe that juts out and runs horizontally just above the line of site for the rear view camera and below the rear view mirror. The sensors never detected this pipe as well. I bumped into the pipe, but was going so slow that I did not realize I had bumped into anything until I got back to the car. I have included some pictures of the damage Asides from the fact that the car is now totally un-driveable , has anybody encountered this issue. I went back inside the car and confirmed that the pipe cannot be seen at all, either by visual nor by the sensor.
