1 Power Train problem of the 2005 Mercedes Benz SLK350

Failure Date: 08/05/2023

The conductor plate along with its speed sensor is faulty. Luckily I just exit the highway, the transmission just stopped working, can't drive forward or reverse and when I apply gas on either d or r, just the rpm speed up as if the car is in neutral. I was stranded on the middle of the road. This happened a few time. After turning off the car and turn it back on usually reset it for a little bit. The first time, I have to replace the transmission.

5 Power Train problem of the 2006 Mercedes Benz SLK350

Failure Date: 10/01/2014

3 issues--camshaft selenoid; defective gear in the balance shafts of the engine; transmission valve body defect. All three of these issues have been documented by mercedes internal documents and there is a class action suit on going for the defective gear in the balance shafts of the engine right now. These are critical issues as the car can lose power. With regard to the balance shaft issues, metal from the shaft deteriorates and that infiltrates the other engine parts causing the engine to prematurely fail. Almost all of the reports on this issue are for Slk350's with less than 80,000 miles.
