Willing to bet it's parts availability..How are the repairs proceeding? Has the delay been waiting for parts, or extra unanticipated labor?
They did replace the rear bumper with one that has the sensors, right? If they did, maybe they forgot to hook them up...Picked it up today.
Gotta say I very impressed with the work they did. I did notice that the guide lines are no longer displayed in the backup camera even though it is enabled on the dash. Also the zoom button (backup camera image) doesn't zoom, just beeps. Maybe the camera had a mini stroke because of the accident? Or maybe I just need to reset the system by disconnecting the battery? I'll certainly take it back to be fixed, but if it is something stupid simple that I can do, I'd be all over that.
