MERCEDES-BENZ Complaints

Exhaust camshaft pulse wheel shifted on camshaft. Replacement of camshaft, positioner, oil control valve, timing chain and chain tension was recommended.

Last April, during our routine oil change our mechanic pointed out that our Cam sensors were wicking oil into the harness and making its way to the ECM. This is the first we had ever heard of this issue and the repair was $2400 or so. After researching the problem we wrote to MB USA and never got any response until we filed a lawsuit in sessions court. Turns out we cant do that locally. Mercedes has never contacted us since we registered the car in 2016 and never even acknowledged us until after we filed the attempt to collect the cost of repair. THE problem is endemic and well known. MB put a poorly designed part on their 270 engines and it could have had a worse outcome had the ECM failed while my wife was driving on the interstate Please let me know what has already been done about this problem and if they are required to notify owners. MB is silent on the issue to the point I feel as though they are hiding something.

I recently purchased my vehicle with under 30k miles in July of 2026. Not long after my purchase my car began roughly idling with a blinking check engine light, and soon after the engine began misfiring. This also cause loss of power when attempting to accelerate creating dangerous conditions in high traffic/fast paced areas. After lots of research I found several reports of owners with cylinder failures. The dealership only responded to fixing the issue after calling them out directly on the issue.

All of the screens in the car failed to start. They remained black while the car was running. Turning the car off did nothing. Drove to a parking lot, turned the car off, got out, locked the car, waited 5 minutes and it still didn't come back. Had to do a reboot by holding the system power button for 10 seconds. This has occurred 3x in 9,200 miles.

The vehicle has had repeated failures related to the air conditioning system and abnormal battery drain when the heating system is used. The vehicle has been taken to the dealership four times for the same issue and has spent more than two months in total at the dealership for repairs. The technicians have indicated that they have not been able to properly repair the problem. The vehicle continues to have unresolved defects affecting its normal operation and reliability. The vehicle has been at the dealer again from 3/26/2026 to present.

Pulled on door handle and handle came off the rear driver side door for the second time.

Rear subframe has rust and holes. Dealer is saying not covered under warranty and asking for $8000

I was informed of this recall fire risk. And I contacted Mercedes dealership where I got the car. And they informed me that the battery is not available at this time. And to park the vehicle outside. I can’t do this because my charging port is located inside my garage. This is not a safe and the dealership won’t do anything about it.

While driving down the highway late at night, with no other cars around, the panoramic sunroof exploded, throwing shattered glass everywhere. The window was not hit by an object and had no previous damage. Shattered flying glass while moving at highway speeds caused a momentary loss of control.
