Three problems related to wiring have been reported for the 2008 Mercedes Benz ML350. The most recently reported issues are listed below.

1 Wiring problem

Failure Date: 06/05/2019

Faulty wiring in the brake light harness that could cause fire. Wiring commonly arcs causing the bulbs to burn out and could potentially cause a fire. Mercedes has other cars with this same problem, but won't address it on the Ml350�s. They even made a part to correct this problem, but demand car owners pay out of pocket to fix mercedes faulty wiring problem.

2 Wiring problem

Failure Date: 07/17/2014

My Ml350 kept blowing it's brake lights. After awhile of this I realized that something was obviously wrong. At this point both lights were out at the same time. I took it in to find that the sockets were burnt out and needed to be replaced. I was then told that the wiring also needed to be replaced and Mercedes Benz had a fix for it all but at a price. I was also told that the c series had a recall for the same problem. Why are there no recall for the ml or the m series?.

3 Wiring problem

Failure Date: 01/30/2014

Rear brake lights went out within short period of each other. Checked with dealer, wanted to replace whole light assembly. Checked online, turns out to be faulty wiring/install for which mb actually has a repair kit. Seems to be quite a frequent problem. In fact the mb c class was recently recalled for that same reason, why not the Ml350???.
