My 18 month old 350ML has absolutely stopped on me about 8 times. It only happens on the freeway when I"m doing around 65mph. I hit a bump in the road, its usually just uneven asphalt. The car loses all power. The dash board lights are on. I have to coast to the shoulder, turn the car off, then restart the ignition. It has always restarted. Its back at the service center...AGAIN. They're driving it around attempting to duplicate "my issue".
Has this happened to anyone else? Any thoughts?

Something to check is.... Do you have alot of keys on your key ring??? I have heard of heavy key ring causing the truck to turn off when truck hits a bump. Don't know how true it is...

Yes, this had happened to me about 3 or 4 times.

The cause was the heavy set of keys on my keychain turning the ignition off.

Hard to believe but true.

Yeah, probably related to a heavy key ring. MB must be proud that there is another new car with the same issue -- the Chevy Cobalt.

It's a dangerous act! and i also mailed into MBUSA, nothing done, sometimes I hate my ML! and one other thing, the tranny mount broke, motor mount broke and Gear shift stick gives a "tick" sound a split second before stop, does urs!???
