Engine Vibration through E350 S & W 212 bodies
My 2010 E550 4Matic was a great and reliable car. My 2014 E550 4Matic is the best E class I have ever had. I only buy V8’s. Maybe that’s the difference in reliability. None of my E class cars have had any annoying electronic issues. I don’t buy cars based on any type of report based on complaints. The complainers never service or maintain their car properly in 90% of those cases.
failing engine mounts, for sure, & possibly from a failing transmission mount.
If you're buying a pre-owned vibrating E212,
negotiate the repair price of $2000 +/-.

I spoke with my mechanic last week about this same question...it has everything to do with the engine that was used in 2010 and 2011...The M272 engine is more reliable than the M276 that replaces it. So many issues with oil leaks were plagued by the M276 that he recommended against buying anything after that, especially anything with forced induction. This is pretty much everything. That's why if you look around, they'll recommend a pre-facelift W212 as opposed to a facelift W212.
An easy way to find out if it is the old vs new engine is the all over black engine cover (M276), as opposed to the two-tone engine cover that looks like a silver 'V' on the top (M272).

Your mechanic is mistaken. I've had two of each M272 and M276. The 276 is vastly superior to the 272. Never had a serious problem with either one.
