We have a 2014 C300. only has 9,000KM on the car. We already had the jerky tranny issue and that was finally resolved.

Now we have an issue when turning. The car makes a rumbling noise and shudders and shakes enough that you can hear the interior squeaking and creaking. Its really strange. Worse at slow speeds and turning wheel fully. ie parking in a stall. It also makes it when driving but less noticeable as the car is in motion

We are going to take it into the dealer and schedule an appointment.
Any idea what this could be? sounds serious. Its like driving and old car thats about to break down. Very disappointing. The headlights also get condensation built up in both of them. Gonna have that looked at.

4Matic?

curious, how many miles (km) did it have when you bought the car? are you the first owner?

bought brand new. it is a 4matic as that is all Canada gets. Must be all the igloos here.

transfer case is the culprit.

transfer case can go that quickly. Sad man. So it was dead from the factory then...

happened to my C300 with only 14.000 miles at the time.


they will change out the fluid in transfer case .
in worst case scenario they will replace your transmission .
factory transmission transfer case is non serviceable.
The remanufactured transmissions transfer case is serviceable .Yes that's what you and everybody else will get ! not a new one.
In my opinion it's put together with better superseded parts.
just make sure if you do get the new transmission that the tech makes sure the clutch pack is properly primed. if not you will be back with the same noise on tight slow right or left turns.
