2010 Mercedes-benz C-class

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.

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.

For the 2010 Mercedes Benz C300, the failure of the steering lock control unit resulted in the vehicle being unable to start its engine. Vehicle was disabled, and I was left stranded. Car had to be towed to my house and separately had to be towed to the Mercedes Benz car dealership service center. The technician at the Mercedes Benz car dealership service center recommended replacement of the steering lock. Yes, this car is available for inspection upon request. This same problem was reproduced in another Mercedes-Benz C300 car that I own. This other vehicle is a 2011 Mercedes-Benz C300. The car was not inspected by the manufacturer, police, or insurance representative. The car was inspected by the Mercedes Benz dealer service center. No warnings or messages prior to the complete failure. This issue first appeared in August 2024. This steering lock failure is a critical issue as I had the same problem with another Mercedes Benz C300 that I own. Both steering lock failures for both cars resulted in the car being unable to start occurred around the same time period and were separately diagnosed and fixed at different Mercedes Benz dealer service centers.

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.

The vehicle had a previous warranty repair for the taillight burning out repaired but the issue has happened per the recall but the dealer states that since they fixed it then they wont fix it again even tho its what the complaint for the recall was originally

Both the front seats tear at back bottom

I had to pull over in the emergency lane to take a very important phone call! Turned off the car and removed key! Upon trying to crank car back up the EIS (electronic ignition switch) failed and the car wouldn’t start back up! This is absolutely dangerous considering the car has less than 100,000 miles on it! This is a known problem with Mercedes and should be recalled! This is going to kill someone if this continues to go unresolved! Mercedes charges 1,000s of dollars to repair something that is happening with w204 generation year of the car!

My brake line is corroded and needs replacing at a cost of $3500.00. I have an extended warranty on the rear subframe due to a recall; however, Mercedes will not cover this costly repair. I was informed by service advisor that I could still drive car with extra caution, as there are no leaks.

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

Rear Sub-Frame Failure almost caused a head on collision at slow speed. Hit brakes and my car fishtailed completely sideways.. - Many many complaints similar to mine on same issue, all on Mercedes C300. Some have reported to this website in hopes for recall and correction by Mercedes. It is extremely dangerous, and expensive to fix. You also do not know there's an issue until too late.
