The brake light warning message for a burned out bulb may be displayed. Our technicians tell us the tail lamp housing may melt and distort causing a poor connection at the bulb. The lamp housing should be replaced to correct this condition.

    I kept getting bake light error on my dash board in my 2007 ML350. The brake light error appearing on my dash board cycles between right and left rear although the light bulbs are not burned out or nothing wrong with them. called 2 Mercedes Benz dealerships to report the issue and even the corporate office with brake light error appearing on dash board even if the light bulb not burned out but were told two different versions of the issue. One dealer said the error is documented and the recall and the fix will be forthcoming in September 2014. The other dealership indicated that this is a known issue with a C class Mercedes Benz but not on the M class. The Mercedes Benz corporate said that the issue of the brake light is for c class only. However, on the internet and Mercedes Benz parts department sell brake light kits to repair that same very issue that I'm talking about.

    I believe that the brake error issue applies to C class as well as M class Mercedes Benz. This Is definitely a "SAFETY issue" that Mercedes Benz has to own up to and mitigated. No should ever get hurt because of a possible poor engineering design on the brake light assembly design

    I had the same problem as others are describing. In effort not to have to rewire the light, I dremel tooled the housing ever so slightly and embry boarded the actual socket connectors just enough to sand off any buildup. That worked for a few days. Seeing other posts about the lack of solid connection, I shimmed the connectors with a cut down piece of plastic coffee stir. One underneath, the other long ways. Laugh if you will, I have never had another problem. Worked perfectly. The best I can tell is the design does not allow solid contact over time causing the problem. Bending the connectors alone won't give the pressure to maintain the required contact. You have to shim the connectors to enable enough pressure to ensure solid contact to the housing. I also put bulb grease on the housing after cleaning it to help avoid future concern. As I say, it has worked fine ever since. Good luck!

    Have the same problem. My technician just check the bulb, and it is good. He told me that whole housing has to be changed, and it will cost me more than $250. I have road many comments about this problem, so it has to be recall on it. So... what can I do?

    I just purchaes an ML 350 from the local MB Deler. I noticed that the rear brake light was out when I got home. I took it to a local MB mechanic and he put a new buld in it but said the whole housing unit needs replacing and will cost $400. He has seen this several times and the wiring that MB uses is inadequate and melts. I scheduled an appointment at the Dealer to get it fixed (hopefully at thier cost). Interestingly enough, when looking on Auto for a second ML350, I counted the number of "bulb replacemnts" or "light housing unit replacements" on 100 random CarFax reports for the 2010-2011 ML 350 and 66% of car reports surveyed have had an issue! Disappointed that MB has not addressed the issue and I think I will look at the Lexus for my second car.

    I am having the same problem as described by others. My brake lights show they are out and it comes and goes. It also swtiches from left to right. I have replaced both lamps and it does not correct problem. This problem should be a recall item. I had problem with a alarm showing my passenger side rear door was open and I spent $2000.00 trying to get it fixed. It turned out it was caused by a leaky gasket on the rear tail light until which let water in and shorted out a computer circuit controlling the alarm signal.

    Display indicated a rear right lamp out. Checked it and no lamp out. Problem light came on and off for days. Took ML350 to my independent shop. They installed repair harness kit (164-826-00-07). Part was $17.50 with $96.00 in labor. No more problems.

    Getting the Left Brake Light warning although the bulb is good. I was told the updated socket harness kit is required for both Left and Right Brake.
