I have almost 70K on the ML 320 and have had very few problems and none of them electrical. I was thinking it may be something with the starter also but it s now been working fine. It was checked twice by a reputable MB dealer with no luck. I guess the problem can t be found now if it isn t happening. Thanks Guys.
PS I ll keep you posted for your information.
