Hello,
I just purchased a 2010 ML350 Bluetec to replace my 1998 ML320. I immediately noticed a subtle but distinct shuddering/shaking/vibration at higher speeds. I brought it back for servicing. They rebalanced the tires, saying "one tire was an ounce off". They also took it for a test drive and proclaimed it okay.

But, I still feel it shuddering - no change at all. Any ideas would be greatly appreciated. Thank you. (By the way, I'm not a hypochondriac - my wife feels the shuddering as well and I didn't feel any shuddering while test driving another ML Bluetec.)

Michael

 

Thanks - I'll do that.
