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

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.

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!

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. Subframe rusting almost from inside out. My control arm fell right out and was hitting the gas tank! I'm thankful to be alive, This needs to be resolved. There are pictures on this forum that look exactly like mine. How sad. https://mbworld.org/forums/c-class-w204/661024-2009-c350-crack-rear-subframe-2.html Thank you for your time. I'm sure you will have many more complaints like this one as chat group considering filing class action if Mercedes does not recall and correct issue. Sincerely, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
Complaint volume is well above typical for a single model year.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
Most recent recall on file: Jan 9, 2019. Source: NHTSA Office of Defects Investigation.
