rocky, if the same dealer has maintained this vehicle since new I would ask why they didn't notice that the harmonic balancer was starting to fail. Certainly your 2008 E320 is not the only one to have harmonic balancer issues. You may also want to ask to see the specifics of the harmonic balancer recall. I know that our 1998 E320 was included in the recall. It sounds like another inherent defect where MB decides at some point to stop absorbing repair costs, and sticks it to their customers instead. That failure is something that should not occur on a $55,000, or more, automobile.
