We had to have the rear end replaced on our 'burb, but it was coming down Pikes Peak that did for it. It ran for years after that. You may want to look for a place that specializes in electrical problems we have one here in this area and you may have one where you are.
I had a Florida Highway Patrol officer tell me that in his opinion the 'burb was the safest vehicle on the road. He bought one for his wife. Weighing two and a half tons might have something to do with that. That was after responding to hundreds of car crashes.
