2011 MERCEDES-BENZ C300 Complaints

I researched that the sunroofs on these models are faulty and have caused water/electrical damage under the carpeting and seats of the vehicles. That is what has happened with my 2011 C300 Sport.

The contact owns a 2011 Mercedes-Benz C300. The contact stated while driving at an undisclosed speed, he became aware that the brakes were not functioning properly. The contact had to pump the brake pedal to bring the vehicle to a complete stop. The cruise control, ABS, and traction control warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic; however, the vehicle was diagnosed with a failure with the electronic stabilizing program control unit. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 84,000.

The brake lines have corroded in multiple places causing brake fluid to leak, potentially creating a safety risk had the problem not been immediately observed and corrected. An independent service center confirmed the problem and replaced all the brake lines and hoses. There were no warning lamps or signals. A puddle of brake fluid under the car was the first indication of a problem.

my ESL (electronic steering lock. ) has went out when I did research this something that always happened please fix

So i was using my car daily for go to work and I was on the highway and they happened a accident in front of me so I have to slow down due to the accident i was going 70 miles per hour and when made a hard break my car turn sideways due to the rear subframe was broke and I dint even notice that the part was rotten they i start looking online and I noticed that the majority of those car come with that factory issue.

I was in a collision and the airbags did not deploy. There was a recall on airbags for the Mercedes C300 within the year my vehicle was made, however, the recall did not include my VIN. Also, the sunroof drain is faulty, which was also recalled on other Mercedes C300s within the same production year, again not my VIN, but upon inspection by a certified dealership, it appears to be the same issue as other recalled vehicles.

Recently I was driving and heard a knocking/creaking noise in the left rear. When braking I felt as though I was going to lose control of the vehicle...vehicle appeared to fishtail and pull to the left. I first noticed it on [XXX] when I was driving on the highway in excess of 60 MPH. On [XXX] I brought it to my mechanic (Genesee Auto Repair, 40 Liberty Street, Salem, NH (603)898-1899) and my mechanic informed me that the left rear subframe had rotted out and told me that I should not be driving the car. There were no warning lamps or messages indicating there was a problem. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The right rear tail light housing harness melted due to an electrical issue. Wire tends to heat up too much. This caused my right rear tail light, right break light and right side turn signal not to function.

The contact owns a 2011 Mercedes-Benz C300. The contact stated that when starting the vehicle, the ignition was not reading the key, and the steering wheel was locked. The message to remove the key from the ignition was displayed. Additionally, the fuel gauge was inoperable and not reading the fuel level. The vehicle was taken to the dealer where it was diagnosed with a locked steering wheel and the steering wheel lock needed to be replaced. The vehicle was not repaired. The contact was informed that the parts were ordered to complete the repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,100.

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.
