Update: BMW dealer figured out that the trailer wiring had a short in it (after the trailer dealer supposedly tested the wiring and went over it inch by inch) which was causing the errors. Works like a dream now :thumb up:
Pulled my RS to the track twice last weekend with no errors!
Kudos to BMW Des Moines for figuring it out

The dealer has had the car on 4, 5, or 6 different days (lost count) and cannot solve the issue. BMWNA claims to have never heard of the issue and has not been helpful at all.
Anyone have ideas?
