Our 05 STS back up ultrasonic rear parking assist (URPA) has failed. Red light flashes whenever the car is in reverse, and does not sense approach to objects when backing up. Have had it to the dealer on two different occasions, and still not fixed. First time, they checked the rear sensors and said they were good, but that it was apparently an electronic module that failed. They ordered the new module, and the car spent the day at the dealership again today. When they called me to pick it up, still not fixed, were unsure what the problem was, called the Tech Support service and, according to them, were told that a TSB on this problem was incorrect and that they should disregard the TSB and replace the 4 rear sensors. I asked if they tested the sensors today, and they said they did and they tested OK; but they were going to order the rear sensors and replace them, to see if that fixes the problem. Kind of like shooting in the dark , and see if they hit anything.
Anyone else had any experience with this problem?
Repair personnel said that GM had so many problems with the URPA that they were not putting them on the 06 STS.
