Hey Guys,

I need your help with my next MB purchase. My wife really likes the R350. I have had many MB diesels and currently have a 95 E300D.

I have been reading about the 3.5 engine and that there may be balancing shaft problem which causes the engine to misfire,vibrate and eventually stall while driving. I am hoping that you guys can help out here and tell me a bit more, like how often this problem may occur and which years. I called the MB customer Service and they were not able to tell me much.

Is it a big risk buying this car? or was the design changed at some point? Can I expect this engine to be reliable?

The that we are considering has 85K on it and it the engine were to fail it would put a big dent on my wallet.

Let me know what you guys have for information.
