This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Sporadically, while driving along on local roads or the highway, the car's transmission does not switch higher than third gear. The problem occurs about once a month. Upon engine restart, vehicle drives properly. My pedal shifters do not work when this problem occurs; I can try to shift gears with the pedal shifters, and the software indicates a change from 3rd to 4th gear, but the actual transmission does not change gears. It remains stuck in third gear whether I speed up or slow down. If I place the vehicle in park and try to reverse, there is no power to the vehicle until I restart the car. This seems to be occurring with more and more frequency. I have a safety concern that I have to pull off the road and restart my car whenever this occurs. This seems to be problematic for several owners on the NHTSA site and online.
Two problems - first, transmission do not switch higher than second speed. Upon engine restart, vehicle drove properly. Second, on another occasion, I was sitting at a traffic light and when I attempted to pull off, the vehicle started driving very slow and rough. I pulled to the side of the road; turned off the engine and waited for a few seconds. When I started the vehicle again and attempted to drive away, the vehicle drove properly. Mercedes dealership is aware of these issues, and also many of people I know who have Mercedes with same transmission type - valve body/electric plate needs to be replaced in auto transmission.
