2008 Mercedes-Benz R320 CDI 76,000 mi,
I too experienced my car stalling while driving 65mph on a very busy highway in NJ. My 2008 R320 CDI stalled with no warning or noise prior; I wasn't able to start it again. Following the tow to the dealer, they informed me that the timing chain had broken and I needed the bottom half of the engine replaced. Thankfully, we purchased a service contract.
