What owners wrote
The electronic steering lock just shutoff. The car came out of comfort while I was driving, the c-in the box-just disappeared off the cluster and I knew this is what happened because it happened three times them started up two days later. This has been a common problem with mercedes c300 as I read so many complaints and posts.
Rear passenger tail lights in my 2008 c300 were dim and got dash warning light to check rear lights. A couple bulbs were out so when I looked at the assembly and pushed on it the lights that were out lit up temporarily and I noticed the cable harness that plugs in it was corroded on the end and the brown wire at the end was exposed (melted?) and the black plug looks warped (melted?), looks like a common problem based on forum reports.
