2009 Mercedes-Benz C-Class

The contact owns a 2009 Mercedes-Benz C300. The contact stated that while starting the vehicle, the check engine, seat belt, and air bag warning lights illuminated. Additionally, the headlights and navigation lights failed to activate for a while. There was burning odor inside the vehicle with the heat activated or turned off. The contact also stated the vehicle failed to start for three days before eventually being able to start. The contact attempted to charge the battery, which resulted in a visible spark. The vehicle was taken to a dealer where it was diagnosed with a sound module and the Signal Acquisition Module (SAM) failures. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 217,000.

Vehicle inspection by independent service center indicated that a new rear frame was necessary. This was the second communication to nhtsa on this issue. This automobile (2009 c300) is inoperable due to this Mercedes rear frame defect .

The problem is that the steering wheel locking mechanism has failed. The vehicle could not be started or driven. It required a flatbed tow to an authorized Mercedes repair facility. It was diagnosed as the steering mechanism, requiring replacement. The cost for this repair is $1400.00. I researched this problem on the MB website and it stated that this issue was common. I feel that this is a safety issue and should be repaired free of charge or at a significant discount. The car is currently being repaired, and I can forward any relevant documentation to you once the repair is complete.

Vehicle has lost its ability to be driven. Car alarm has gone of a multitude of times at different hours of day and night. Finally we were told that the steering column needs to be replaced. According to tow truck driver, Auto lock person, this is common from the 300 series of Mercedes Benz. Obviously very costly. My car is worthless at this point. I believe that the Mercedes Benz should have a recall on the steering column lock. Obviously, this is not only a defect but, also causing safety issues with it just turning off and not able to restart.

While driving the car on [XXX] at 9pm on sunday, [XXX] in lane two during a heavy rain a audible clicking noise came from the drivers side front of the dash instrument cluster area and all of the lights on the car simultaneously turned off without ever touching the light switch i was unable to see the road in front of the vehicle also the windshield wipers quit working and the radio and navigation display went off and closed and opened and closed( turned off and then on and off again) the instrument cluster went dark as well, luckily i was able to turn the steering and apply the brakes and steer the vehicle onto the shoulder of the road and come to a complete stop after several attempts to turn the headlights back on i determined that the vehicle was not safe to drive , and had the vehicle towed to a reputable mechanic, and upon diagnosis he contacted me and stated that the drivers side front signal acquisition module A. K. A. the (sam) module had failed due to water intrusion into the fuse panel sam module area , the mechanic stated that i should file an incident /complaint form with your office , upon searching the MERCEDES BENZ forums and sites on the www i found many customers with a broad range of models (w204)approximately this same year model have identical complaints and nothing has been done by MB usa to remedy the problem, i believe this matter to be a major safety concern and i am wondering why this matter hasnt been taken into consideration by your agency and by MB usa as a safety recall to replace the failing modules and retrofit the fuse panel sam module area to prevent water intrusion thats causing the obvious safety concern and possible liability on the part of the MB/ DAIMLER corporation. it seems this is clearly a problem and it needs fixed we are terrified to drive the vehicle for fear of a repeat incident.

Check Right Tail and Brake Lamps warning light will not go off for months. They are working fine but the light won't go off. Googling on MB World, it shows Mercedes is aware of this problem and a recall is needed to get it corrected being safety issue with warning lights not working properly. See all info. below from owners, conversations and work done by dealers, etc. People note it is a middle school education problem. Please alert me when the recall is confirmed to get this important problem fixed.

Went to the Mercedes dealership service department to replace the rear subframe that suddenly broke while I was driving due to extreme rust/corrosion. The dealership stated that it was being covered under the extended warranty due to the recall related to the rust/corrosion issue with the subframe. I was advised by the mechanic that the brake lines will need to be replaced due to extreme rust/corrosion in the rear at the same exact location of the rear subframe, making the vehicle very dangerous to drive because the brake lines could break at any moment and cause sudden brake failure. I was quoted a very significant amount to replace the rusted brake lines and per the dealership, it will not be covered under any extended warranty and/or recall.

The contact owns a 2009 Mercedes-Benz C300. The contact stated that while driving at various speeds, the rear end of the vehicle would fishtail and become extremely unstable while driving over a bump in the road or while turning. Upon inspection, the contact discovered that the subframe was severely rusted. The cause of the failure was not determined, and the vehicle was not yet repaired. The local dealer was notified of the failure. The manufacturer was not contacted. The failure mileage was 201,000.

I drove my car to get lunch. Came back out to go back to work and the car would not start. Would not even turn over. My Radio did not turn on and I couldn't even roll my windows back up. Luckily they were only cracked open a small amount. My steering wheel cannot be turned, it's locked in it's current position. I am told the ESL (Electronic Steering Lock) and possibly the EIS is the cause of this problem. The display on the dash says "Take your key from ignition" and that is all I get. Had to have my car towed and now I have a dead car with the windows partially open that I cannot close.

Headlight harness on drivers and passenger side is melting and my lights are flickering. I was advised to night drive my vehicle at night, because it could start an electrical fire. This is caused by heat from the lights.

The entire rear subframe of any W205 body model including but not limited to the C class from 2009-2014, CL class, SL, class ETC. suffers admittedly from MB USA, premature rust, deterioration etc. there is an active recall for these same models in Canada and all of Europe but not the USA. My garage kept 2009 C300 has suffered extensive rear end damage from a factory defect that Mercedes refuses to recognize in the Continental U.S. but will admit the same issues occurred in the EU and Canada. Keeler Mercedes, USA, of Colonie New York, stated they completed my subframe repair under the MB rear subframe extended warranty. The vehicle was driven home and inspected only to find out Keeler Mercedes of NY did NOT replace this crucial safety component under MB-USA extended warranty issued for this defect. This is pure negligence. When asked why the subframe wasn’t replaced as the work order stated it did, they stated “a mix up in paper work” I believe Mercedes-Benz USA and Keeler Mercedes of New York conspired together to push this massive safety defect aside and lie about completing the work in fear of the payment from warranty not being worth the labor hours required by the technicians. This oversight COULD have been a multi million dollar lawsuit if any injury was sustained after said repairs were done in belief the vehicle was safe to drive. Keeler Mercedes’ has also had this vehicle in their possession from June 14th 2024, to todays date, July 5th 2024 with no word on when repairs to subframe will be completed. Subframe replacement stated on MB website states it is an 8 hour labor job. We’re on day 18 now. MAJOR safety issue and shady dealing by dealership

The contact owns a 2009 Mercedes-Benz C300. The contact stated that while driving at an undisclosed speed, the "SRS System Requires Service" was displayed. The air bag and check engine warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the vapor canister shutoff valve but had not provided a diagnosis for the SRS system. The vehicle was repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 99,000.

After noticing brake fluid leaking I took my car to a local automotive shop and when he raised it to checkout the break line when he found the leak from the rust . he noticed a more serious problem that the subframe was rusted out on each side. He told me to contact Mercedes immediately because the car is unsafe to drive.

Last week just before Thanksgiving my car of 134,000 miles wouldn't start. Had it towed to my mechanic only to find out like so many others that the Electronic Steering Module(ESL) is 1,500.00 defective. Yet with this being a common issue there is no recall. guess I'm going to a Toyota.

As I was driving from work, I noticed that when I started using the brakes I starting hearing a metal sound coming from the back, the day after I looked down and realized a whole part from the sub frame was completely broken and the part is corroded.

The caption and case number is Sowa et al v. Mercedes-Benz USA, LLC et al., [XXX] MBUSA has extended the warranty on the rear subframe of several vehicles. The link to this in on your website: [XXX] One the last page of the PDF file on your website it states: When will customer letters be mailed for this warranty extension? The warranty extension customer notifications are scheduled for mailing on: March 10, 2023, and continue in waves through May 19. We have three cars in my family that are in this "extended warranty" at three different households. No letter was received at any of the three households regarding any of the three cars. If you look up the three cars Vin #'s, all three have no recalls on them and nothing relating to an extended warranty on a rear subframe. So, MBUSA, has brilliantly side stepped issuing a recall which would come up on a Vin $ search. They have not sent out the letters of notification. So, almost all owners will not be aware of the deadly impending time bomb they are driving. As these cars age further the ones that have yet to fail will fail and people will die. I called today, 10/24/2023 Reference # for the call [XXX] to let the NHTSA know the above and that if you allowed MBUSA to NOT issue a recall because they agreed to send letters of notification - well they did not do that and people are at risk. This seems like a loophole to me. No recall, we will extend the warranty and then not let anyone know much lower cost than recall and fixing. The NHTSA - should get the contact information for all the customers affected and hire a third party to send the notices and have MBUSA billed for that service. This would ensure people are notified. I was advised by the NHTSA staff on my call to file a claim with the BBB. That seems ridiculous. I will keep a copy of this filing; so, I can send it to the news channels to show how the NHTSA given due notice did nothing.

Total shutdown of complete system…brakes, steering and engine at around 25-to 30 MPH. No warning. Happened two times…once before M-B service and once after service for problem. It checked out OK from dealership months before only to have it happen again. Was lucky to avoid a crash both times. Sold to dealership. Wrote my safety concerns for a new owner to local dealership and corporate.
