First Problem
 

Just under 2,000 miles and yesterday my parking sensors, back-up camera, and garage door button stopped working. It seems like anything that involves sending a signal has died. Anyone experience this on a BMW? Thanks.

Could you elaborate more?
What were you doing with the car when those functions last worked?
Did you contact BMW asap since I assume the car is fully under warranty still.

Did some running around during the day on Sunday, maybe about 20 miles, everything worked fine. Came back home and pushed the button for the garage and wouldn't open. Opened with the spare remote, then when I pushed the park assist button once in the garage, it wouldn't go on either. Put car in reverse and back-up camera would not come on. Yesterday was the same thing on the drive to and from work. This morning, however, backing out of the garage no camera, then about 5 feet into my back-up, the camera came back on and I was able to use the homelink to close the garage. Everything seems fine now. I made a service appt. for Friday so still going to keep it. Something caused it to happen and want it checked out, even if no more issues up till then.
