I just got a new 07 S83 and the dealer left the negative battery cable loose. It started cutting out just after I topped off the tank and I asumed that I had gotten water in my gas. I added heet and drove it in spite of its objections, but realised after it would not start that it was electrical instead of fuel related. That battery connection is in a terrible place and could see how they left it loose. That does not excuse them though. I am wondering how I will tighten it up when the battery needs to be replaced and the warrenty is out. Has anybody had this problem. Do you know an easy fix?
