We thought that our car was burning out the rear bulbs really fast or that there was a short. Turns out that when we took it in for repairs to the balance shaft, we found out that there is indeed a short in the harness. Apparently, the C-class is not the only model having this problem.

Rear light modules (tail, reverse, brake, signal) keeps on failing. Dealer quotes initially $200 to fix/rewire but then goes up to $800 to replace ECU. This is frustrating as this is driving hazard, owners are left without much choice. I have seen multiple complaints of the same issue so mb should already know that this problem exists and be honest upfront about it. I hope nobody gets hurt if the lights fail while driving this model/brand.

Tail lights does not illuminate, just the substitute bulbs. I changed out all the bulbs but still no stop, tail lights. Fuses all good.

On my 2006 Mercedes Benz R350, the rear brakelights and taillights regularly fail to eliminate. The lights are very inconsistent and when they fail a back-up substitute light comes on. A message appears on the dash indicating that the substitute lights are on. After changing the bulbs numerous times, I was told by a mechanic at Mercedes that the contact may be worn out.

Our 2006 R350 had all the tail lights burn out at the same time resulting in a safety issue. There appears to be a common issue with this model and year with a wire harness that controls the rear brake lights. When this harness fails the tail lights stop working. Mercedes knows about the issue and has a tsb on it, but will not cover repairs if the vehicle is not under warranty. There are multiple complaints on online Mercedes forums regarding this defect.

Headlamps shine too close to car. Only shine 40-50 feet out to the front and at night, especially in rain, you absolutely cannot see the road or hazards in it, such as deer.
