Rear light modules (tail, reverse, brake, signal) keeps on failing. Dealer quotes initially $250 to fix/rewire but then goes up to $950 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.

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.

2006 Mercedes Benz R350 stalled in the middle of a residential intersection shortly after the car was purchased. Within a short period of time after getting the car, we also felt a strong jerking then shifting gears, but it was doing it on its own. We took it in and was told it's just loud. Then we were told there was a recall. They were supposed to fix it but it never stopped. The check engine light continued to come on. Other issues related to the engine had to be fixed rather quickly. The car was purchased in the end of 2005, and has 88,000 miles. Over a year ago, the car began idling/shaking really bad. I called mb roadside and was told that it was probably because the gas cap wasn't placed back on the car correctly and gas was leaking. I had the car checked and there was no gas leaking. The car was taken to the dealership where I was told the intake manifold was broken and needed to be replaced before anything else could be diagnosed. The car is still idling bad and check engine light is on. It is now back at the dealership it was purchased from for a diagnosis, which I should receive tomorrow.

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.
