1 Exterior Lighting problem of the 2012 Mercedes Benz C Class

Failure Date: 10/25/2025

The taillights in my 2012 c300 was starting to go out intermittently. At first the notification came on for the brake light but the brake light kept working. Afterwards the rest of the taillights and the sidemarker light went out as well. I went to go take a look and the grounding wire was oxidated and corroded. A known issue in which there was a recall made for the 2008-2011 version of the w204 but this did not apply to the 2012 w204. As of last week my entire rear drivers side light is out which is a safety hazard especially at night. The hazard lights dont work in case of an emergency on one side, the brake lights are out to notify the driver behind me take I need to stop which can lead to a rear end collision, as well as the left turn signal not working leading to drivers not knowing that I will be turning left or needing to merge left as needed. All of this is a known safety hazard to mercedes but no recall has been submitted yet.

5 Exterior Lighting problem of the 2001 Mercedes Benz C Class

Failure Date: 10/15/2003

After leaving my 2001 clk320 mercedes at the dealership I was notified that my brake system was defective requiring pads/rotors and other related items along with the fact that every 1000 miles or so, a light bulb or something electrical will fail and I usually find the nearest dealership and get the problem fixed. The brake system (which is not under warranty) was the last straw! we are talking about a 50,000 dollar automobile with only a little over 17,000 miles on it.
