Three problems related to brake light on have been reported for the 2009 Mercedes Benz C300. The most recently reported issues are listed below.

1 Brake Light On problem

Failure Date: 08/08/2013

On 8/8/2013 my information display indicated my right taillight, blinker and brake lights were out. When I opened the compartment to see what type of bulbs to replace I found the problem to be much bigger than expected. The plastic housing that hold the wiring pin, the wiring pin and the brown ground wire were all burnt up causing the lights to fail. I than opened the left tail light compartment and the same thing is happening, there is already signs of the housing burning. I remember smelling something burning in the car a few weeks ago. I now know what it was. I am surprised it did not catch fire. I contacted mercedes service only to find I am responsible paying to have this issue corrected. I only hope the left side does not cause a fire before I am able to get it fixed. This is clearly an unsafe electrical issue.

2 Brake Light On problem

Failure Date: 12/16/2012

Warning on dash shows rr brake light is out and turn signal lights is out. Went to look at the back of the car to see if the lights where on and the rr light assembly was dim. Open the panel where the bulbs are and the wire harness was fried. This might be a fire hazard.

3 Brake Light On problem

Failure Date: 08/05/2011

Front brakes checked by an independent shop and was advised that front pads have uneven wear, inside pads was 2 mm, outside pad at 8mm because the caliber is not squeezed in evenly. Bring the car back to dealer under the 50k miles or 4 year warranty for brake checked: dealer only replaced the brake pads but not the caliber with reason the hardness of the pads are so soft and cause the issue. Mb dealer is not standing with warranty on the engineering mechanical defect: try to make a quick fix and not expensive only on a major problem. After 5k or 10k, the uneven will occurred again and the service brake light will not on because of the uneven wear, will cost more money for me on the rotor, brake pad and caliber again. An investigation and a recall from mb needs to perform for all the mb C300 year 2009 for a caliber check.
