The Brake Light Warning Message May Be Displayed on Mercedes-Benz ML350

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.

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?

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.

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 trader.com 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.

Bought the ML350 used and have changed 3 bulbs since February but the same "left brake light" message keeps coming up! Very frustrating!

battery light came on while driving, car started several times fine within hours, then it was hard to start, it started but various warning light came on and the car was riding very rough, maybe wouldnt get out of 2nd gear, pulled over and it stalled and wouldn't start started with a jump but no headlights radio etc, stalled again and we are having it towed
Both the left and right brake lamp warning will appear. The bulbs are good. The light will work sometimes, and out others. Just bought the car used from a dealer, bringing back to have them install repair harness kits.
4 new bulb replacements in 4 months
I am having the same problem with my ML-350. The first time it happened, I went to the MB dealer and bought a new bulb and a tech replaced the bulb for me. I thought that it was fixed. The next day, the warning light came on. So, I pull the bulb out and the 2 tabs were blackened and burnt. I took an emery board to the contacts and it would only work intermittently. I took it to the MB dealer and they said that the wiring harness on the left side had to be replaced and they wanted to do this for the right side also as a preventative measure. They said it would cost $389 to do both sides. I declined and will seek help elsewhere.

Brake light socket not grounding - both sides - clean and will work for a short time.
2010 Mercedes-Benz ML350 60,000 mi,
Same as others- even with bulb replacement brake light still going out. Brought it to MB and they had to replace both circuit boards.

Mercedes 2013 C-250 - false dashboard warning light keeps coming on for left rear brake and tail light every day but my lights are ok!
2009 Mercedes-Benz ML350 75,000 mi,
Brake Light Right message displayed. Went to a mechanic who tried to replace the bulb...only to find out that the bulb is not the problem. He suggested replacing the bulb socket. I will replace the bulb socket to see if that helps. Will keep forum posted.

right brake lamp warning light comes on intermittently

I bought this used in 2014. I have messages on all the time about lights being out (averaging 6-8times a year). I have replaced these bulbs and with the exception of the brake lights stating they need attention the warning lights shut off. There should be a recall on this. I'll see if my husband can fix the light harness first and of not, I'll be taking it to an independent shop (nearest MB dealer is an hour and a half away).

It is not fixed. I tried on youtube to find a solution. Guess I will have to take to shop/
2010 Mercedes-Benz ML350 42,000 mi,
Right rear brake light warning keeps coming on. Replaced the bulbs (that didn't need replacing) and the display is still on. Terrible
2011 Mercedes-Benz ML350 85,000 mi,
Replaced the light bulb like 4 times already. The mechanics told me the housing of the bulb needs replacment because its not makin good contact with the bulb.
2010 Mercedes-Benz ML350 89,000 mi,
LED brake lamps on both sides are failing. MB of Danbury said the fix is to replace the entire housing, $600 per side, including labor. Outrageous.
