Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

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.
