MB has never officially acknowledged a problem with the engine, but they do fail (bent rods) in normal service. The rods have been re-designed and are now much heavier than previously.

Some people have had good luck getting the engine replaced under warranty, but if you are out of warranty, it can be a large pain to get any statisfaction. New engine is EXPENSIVE, even a short block can be prohibitive.

There is no official program for repair or replacement, either.
