2012 MERCEDES BENZ C300 Electrical System Problems

I was replacing rear tail light bulb. Now I'm getting an error message on instrument cluster. I tried to fix the issue but couldn't do to the fact the wiring harness has melted. Mercedes Benz had a recall back in 2013 saying this is a safety issue. No recall for our car.

The contact owns a 2012 Mercedes-Benz C300. The contact stated that after opening the sunroof and then attempting to close the sunroof, the sunroof failed to fully close. The contact had to open and close the sunroof several times before the sunroof closed. Additionally, the contact stated that there was water entering the vehicle from the sunroof which caused electrical failures. The contact stated that the vehicle was drivable, but the "Anti-Theft" warning light illuminated. The contact stated that several other warning lights were later illuminated, and the vehicle would not start. The contact had the vehicle towed to a dealer who diagnosed the vehicle and determined that water had damaged the driver’s side electrical wiring harness. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 169,000.

Mileage: 169,000

Vehicle will not start, possible ESL/EIS failure.

While driving, engine stopped, could not steer.. Looks like a defective Electronic Ignition Switch or steering lock! It seems to be a common problem on these cars!!! The car would not start. After 8 attempts, I was able to start car but was afraid to drive it. Could have been a disaster.

Car will come one as normal next day car comes on no lights not 1 button work turn signals didn’t work then my car fan came on in the engines the also the when they the electric isn’t working i have to manually shift the gear

TL* THE CONTACT OWNS A 2012 MERCEDES BENZ C300. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 45 MPH, A BURNING TYPE ODOR WAS PRESENT INSIDE THE VEHICLE.

UPON STARTING THE VEHICLE I RECEIVE AIRBAG WARNINGS. ONE FOR THE DRIVER SIDE AND ANOTHER ONE FOR THE PASSENGER SIDE. I CAN CLICK ON "OK" TO CLEAR THEM OUT BUT WITH THE AIRBAG RECALL AND NO RESOLUTION I AM FEARFUL OF A MALFUNCTION. I HAD MY CAR TO THE MERCEDES DEALER TWO TIMES AND WAS TOLD THEY WOULD NEED TO INVESTIGATE IT, AT MY EXPENSE, WHICH COULD BE ANYWHERE BETWEEN $500-$4500 DEPENDING ON WHAT THEY FIND. WITH A SAFETY ISSUE AT RISK I THINK THE RESPONSIBILITY IS ON MERCEDES TO INVESTIGATE AND CORRECT THIS AT NO EXPENSE TO ME. I WILL HAVE TO SELL THE CAR AND LOSE MONEY OVER IT. I KEEP WAITING FOR THE AIRBAGS IN RECALL TO COME IN AND HAVE BEEN LIVING WITH IT LIKE THIS FOR OVER A YEAR BUT I AM SEEING NO END IN SIGHT TO THE RECALL BEING RESOLVED ANYTIME SOON.

IT HAPPENS SEVERAL TIMES BEFORE IT COMPLETELY FAILS.
