My ML320 completely shut down on a bridge in Trenton NJ. No power, no lights, no radio. I was able to coast over to the side of the road. I turned the ignition off, and then on The car started. I was told by Mercedes this has never happened before. A lie. One of my employees bought the same model car from the same dealer, and has returned it 3 TIMES with the same problem (unbeknownst to me at the time). Has anyone had this problem. MERcedes made me buy a new battery. We all know that was not the problem.
