NHTSA complaint #11580578 — an unverified report by a vehicle owner.
EXTERIOR LIGHTING
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.

EXTERIOR LIGHTING
The driver side rear tail light wiring melted the tailight housing. This component was already replaced as part of a previous recall, but apparently Mercedes is not properly fixing the issue. They refuse to fix it for free, because they already "addressed" the recall. Looks like they are putting cars back on the street that could catch fire.

EXTERIOR LIGHTING
My husband drove my car home from work on April 18th 2022 and it was a bad rain storm that everyone. He had to drive through a couple of big rain storms. Soon afterwards he got around the corner from the house and the electric system failed lights started going off everywhere in the car, he lost steering and couldn’t see and almost crashed and got the car home safely but it wouldn’t shut off so he had to disconnect the battery for the car to shut off. On April 22 nd the car was towed to the dealership because it wasn’t driveable and they check out the car and discovered water under the carpeting of the drivers seat near the wiring of the car. I submitted an insurance claim and an adjuster went out to see the damage and his thought is that it’s due to a known problem for this car that’s been reported by many people with this same vehicle. The Mercedes Benz c300- 2010-2014 years. I checked online and apparently many people have reported this same issue water underneath the car due to bad firewall manufacturered not sealed correctly which could be a manufacturers/ safety issue. My husband was almost killed thank goodness he made it home safe that night. I believe there are many people that have had this issue and someone needs to be done for safety purposes, and I believe the insurance doesn’t want to cover the repairs because they are blaming Mercedes’ Benz. My cars been in the shop a month and I still have no answer from State Farm or the shop Mercedes Benz.
