The other day I was driving my ML 63 and heard a rattling.
The car stalled and would not restart. The message board said to take it to an authorized dealer for repair.
I towed the car to my mechanic. He discovered my oil pan was punctured from something that broke loose in the engine and caused the engine to seize.
He now recommends replacement of the engine.
I noticed that many people have had engine issues with this model.

Has any one had success getting Mercedes to pay for the repair?
