2010 Mercedes-Benz C 300 Problems

After having the airbag recall for my Mercedes done, the Electronic Steering Lock failed and my car would not start and the steering wheel is locked. They said my car was ready to pick up and when I arrived the car was completely inoperable. The MB Dealership in Lynnfield, MA wants $2700 to fix it. If you google Mercedes W204 ESLfailure you will see thousand of owners on facebook, message boards and forums that have this part fail, leaving people stranded in sometime dangerous situations. There should be a recall to permanently fix this issue as owners are getting stranded. Its really an issue of "when" the ESL will fail on older models and not "if". The kicker is, the dealership said only they can fix the problem as it is an anti-theft issue. This seems very wrong, owners shouldn't be forced to pay Mercedes to fix their defective, cheap electric motors in the ESL that fail on almost every model that its in. These defective motors are what causes the steering lock failure in almost every instance. MB acts like its normal to be driving properly one day and then next your steering is completely locked and your car will not start because a $15 electronic motor in the ESL failed. Furthermore, these are All wheel drive or rear wheel drive, in addition to the locked steering wheel which makes towing very, very difficult and unsafe. Thank you

While i have a few recalls i plan on needing service from Mercedes for, I just found out that Mercedes has a Class action lawsuit involving my C class mercedes C300 from 2010-2022 years. I was driving and ran into a pothole. My car rear started making noise and sounds. I went to the auto shop amd was told my rear subframe was damaged and would cost over 2,000. I and putting in a complaint to make sure Mercedes honor this recall/ extended warranty for my vehicle.

The contact owns a 2010 Mercedes-Benz C300W. The vehicle was taken to the dealer for an alignment. The contact was later informed that the wheel alignment was not fully completed due to extensive corrosion on the subframe. The contact picked up the vehicle and upon investigation discovered that there was a warranty on the vehicle for the corrosion of the subframe. An appointment was scheduled, and the vehicle was taken to the dealer where it remained for two weeks. The contact was later informed that the condition of the vehicle did not reach the warranty standards for repair. The vehicle remained in the possession of the dealer unrepaired. The manufacturer was notified of the failure and the contact was informed that dealers were independently owned and made their own decisions on warranty repairs. The failure mileage was approximately 63,000.

Dealer notes, fuel tank, and hold down straps are rusted and rotted

Rear sub frame is corroded as shown to me by the Mercedes mechanic in a video he sent me.The car is available for inspection. I am nervous to drive now after hearing about the related problems others are having such as braking issues and swaying when the brakes are applied. The way I found out about the rear sub frame corrosion was when I needed work done at the dealer. This problem should not be happening to all of these vehicles. In other countries, Germany and Canada, to name a couple, Mercedes dealers are fixing this through a recall. Why not the US? The date below is when the mechanic told me about the problem and that it would cost $8000. to $10,000 to repair

MY VEHICLE WAS RUNNING SUPERIOR, NO WARNING SIGNALS OR STRAINING WHEN POWERING ON. PARKED CAR THEN AN HOUR LATER TRIED TURNING VEHICLE ON AND WILL NOT TURN ON FOR ANY REASON JUST RADIO WORKED. FOUND OUT IT WAS STEERING MODULE NEEDED TO BE REPLACED FOR A HEFTY $1100. HAD THE CAR FOR ONLY 3 MONTHS AND BARELY USED IT. I BELIEVE IT'S A RECALL ON THESE ISSUES.

Rear subframe rust out and rear passenger brake line corrosion. The entire subframe has to be taken apart in order to reach the brake line. The vehicle is due to get the rear subframe replaced as part of the warranty extension. The brake lines are not covered. Took it into Mercedes Benz Dealership in Santa Fe, NM. They will not even touch it because they don't even know how repair it.Also they never done this type of work.

The right rear brake line had rusted out and caused complete brake failure while driving. If this occured at highway speeds it could have resulted in serious injuries. A search has shown this is widespread with the C300 and other mercedes vehicles and although mercedes has acknowledged this in other vehicles it has not done so for the C300. This is a potential for serious bodily injury and should be addressed.

Due to the corrosion in the rear subframe both side of lower control arms snapped the tires to the car are wearing out due to the corrosion in rear subframe and it’s was also hitting my gas tank if I was to go over any holes which can cause a bigger issue

THE FORWARD MOTION WAS VERY FORCEFUL AND THE IMPACT WAS HEAVY. THIS WAS UNINTENTIONAL ACCELERATION, AS I HAD NOT DEPRESSED TO ACCELERATOR AND WHILE I AM DEEMED AT FAULT I FEEL THIS MOVEMENT IS DEFINITELY RELATED TO ANOTHER INCIDENT IN THIS VEHICLE REPORTED ON MAY 21, 2011.

I WOULD LIKE AN INVESTIGATION TO THIS PROBLEM, SINCE THERE IS EVIDENCE OTHERS HAVE REPORTED THE SAME PROBLEM. *KB
