We had notifications on our dashboard that rear driver side (left) lights were out while driving car. We thought the light bulbs just had to be replaced. We brought to mechanic to just fix lights & they discovered the light ground wire burned out & caused light holder to be damaged as well where ground wire was. It caused rear driver side tail lights to fail. We had light bulb holder with wires all replaced on 2/23/24. This issue was a recall back in 2014 & seems to be a reoccurring issue with this part of the Mercedez 2011 C class.

The sam box (electrical system fuze panel) located under the hood is in a spot where if the lid isn't on correctly water will drain from the windshield right into the sam box and cause the vehicles electrical system to deploy the steering wheel airbag. That's at least what happened to me. It was raining out that day and I guess I went over a bump that caused the lid of the sam to get out of place. I drove home and the car seat for a few hours. I went out upon unlocking the door as soon as I pulled the handle to open the driver side door the steering wheel airbag blew and the vehicle is now in srs mode. The dealership had told me that it's a design flaw but wants me to pay for the diagnostic. No lights were on and I did not file a police report.

the rear subframe on my car rotted out. Before they called a recall/extended warranty,I paid to have it fixed. Since it is a 2011, I was not about to pay $7,000-$9,000 to get a new one.

the rear subframe on my car rotted out. Before they called a recall/extended warranty,I paid to have it fixed. Since it is a 2011, I was not about to pay $7,000-$9,000 to get a new one. I made the best decision with the information I had at the time. It broke in June of 2022. I had the car fixed with a used subframe from Atlantic Auto. Once I realized there was FINALLY a recall/Extended warranty, I submitted All necessary paperwork and have been denied. I wrote to Mercedes Benz Corporate office. They contacted the Warwick store. Went back and forth All summer and they have refused to reimburse me the &2,299. that I spent to fix the car. It says the decision is made on a case by case review. They have denied my claim. I have all the correspondence between myself and Mercedes Benz.

The subframe has rusted/fallen off. This is incredibly risky as the car cannot be driven safely and it happened without warning. My mechanic said it is not due to any driving incidents but through rust occurring on Mercedes' subframes, which are flimsy. It has been inspected professionally by a mechanic. There are NO warning lamps. This could kill someone on the highway as while braking the car veered left and right. I had small children in the car we all neck pain from the car veering while stopping on the highway. I have taken good care of my vehicle and have all maintenance current. This is a fault with the material on the subframe. For MB: All the subframes are on backorder and are incredibly expensive to fix. I have a video of the damage from the mechanic if needed.

On 8/3/2023 we could smell a strong gasoline smell inside and outside our 2011 Mercedes C300. We towed the car to a Mercedes specialty repair shop for inspection. The found that the passenger side fuel pump cover (which is a large cylinder assembly actually) was leaking due to cracked plastic. Gas vapors could be detected outside the car, in the trunk, and in the car as the gas tank is right under the back seat. Our mechanic said he had just fixed another Mercedes with the exact same problem. Apparently this is a well known defect and I understand that Mercedes has an extended warranty for later models. We believe the extended warranty should be extended to our 2011 C300 which has only 55,000 miles.

Over the weekend my vehicle driver side interior door handle became inoperable not allowing me to open my door from the inside. The handle flaps back & forth with no connect to the inside of door panel not making be able to get out of my vehicle. I was stuck & had to climb over to passenger side to get out. It only opens from outside . It has been functioning well for the life of me owning the vehicle, never giving me any problem until now, suddenly with no warning that it was breaking. My Mercedes dealer said I need a whole door panel & they have had several calls from other C300 owners where this handle broke also recently. So they are aware & admitted so. This is a recall or factory defect in my eyes. Also I looked online & this is very common because of a plastic not metal part Mercedes uses . Is this not unsafe enough to be recalled? It’s a no brainer! Not bein able to exit your vehicle at all. I was so scared and shocked a car of this class has this safety issue and they do not do a thing to their owners to fix it, its on owner and their pockets. This should be taken care of immediately for free. Are they waiting for someone to have an accident and lose their life to act on replacing this problem?! Again I feel this is a major safety recall that needs to be addressed ASAP. Safety, peace of mind, accessibility to exit/enter your vehicle. If no one can help you from the outside, you have to climb out from passenger side or thru the back of the vehicle. You can open your window too, but what if that jams electrically ….you are stuck. $900 plus labor should not be on me but should be in Mercedes hands to value my life & others lives more than any price as a standard part of their fleet of cars they have driving across USA. High end luxury car w/a faulty door handle that leaves you unable to get out, unbelievable ! Has safety hazard written all over it. I have a video & submitted a pic of my issue. This is my second MB I owned and I never had this danger occur.
