So I recently got my 2013 E550 back from having some warranty work done. Has ~43k miles on it. I was getting a vibration at cold startup and at 1500 rpms that was shooting through the chassis, so they replaced the motor and transmission mounts. The car actually handles better as well and is better over speed bumps, so my guess is they were actually pretty shot.


Now, I still get the cold start startup vibration, it feels a bit worse (but admit it may be in my head), but doesn't last as long. I don't know if new mounts need to 'break in' or anything, and it completely goes away once it is warmed up. If I shut her down and get back into it (like go in to get a coffee) it doesn't happen but if it sits all day (like when at work) it does.


I notified the MB dealer to ask if they had any ideas. I won't plan on bringing it back in unless they tell me to, or someone here indicates I should be REALLY concerned. Car is fantastic in every other way.


Any ideas? My guess is they will tell me it's normal, and I have been surprised but what is 'normal' already (the decoupling driveshaft while stopped was a weird one, and the exhaust rattle for 2-3 seconds apparently is normal), so wanted to see what folks here had experienced, if anything.


Thanks in advance!

I have the same vehicle and same issues. I feel the vehicle vibrate in a shudder like fashion. It periodically shudders at start up and idle. Replaced motor and tranny mounts which seemed to help a little but problem persists and dealership is out of answers. Between this, the burning smell & weird noises after a drive, and constantly hearing "that's normal" from the dealership I'm seriously considering going back to the W210.

You could just get the 2010 or 2011 w212, I don't get any of that stuff in my 2010.

Burning smell ???

My '11 E350 shook on startups occasionally, but stopping and starting again made it right. Not sure what the issue was, and I could never recreate the symptoms on a whim to justify bringing it to the dealer. My E550bt hasn't done that... however, it does have a noisy clanking (probably center diff) that sounds like a diesel truck at idle. My G37 made the same sound, but I had a stage 2 clutch and flywheel which was causing it there. Have a list of checks for my dealer the next time I go in for service.

Thanks for the help fellas. Nostalgia for the DIY friendly W210 just gets me sometimes.

Anyway, burning smell started after dealership changed tranny fluid and lets just say 3 trips back and a lot of conversations later, the leak they caused was finally repaired properly. Evidently some spray remains and thus the smell and dealership says they don't offer undercarriage cleaning. Will look into again once its due for service. Sometimes a new service manager makes all the difference.

Vibration varies and cant find what causes it - harmonic balancer maybe? BTW - vehicle is a 2010 E550. I just re-read OP's post and it clearly states 2012...so my bad.
