Owner report 11468667 · 2022-06-10 (June 10, 2022)
Our vehicle is stuck in park. Driver message system says “Do not shift, Contact Mercedes”. We have the Mercedes Sprinter 3500 XD chassis. While our vehicle had this happen in our driveway, internet research to resolve our issue revealed several Sprinters having the same issues while stopped in traffic.This is our second incident involving Mercedes dealer intervention. While we are inconvenienced, one could understand the dangerous impact a stalled rv on a interstate could become. We have not received any solution from Mercedes.

I was on a 2 1/2-week vacation driving on [XXX] near Lacy Washington and was in the middle lane moving over to the slow lane when the vehicle just stalled.

Owner report 11500837 · 2023-01-09 (January 9, 2023)
The message center displayed “Service Advance Trac” and the cruise control stopped working. Right after this event the steering wheel was no longer straight when driving straight but angled counterclockwise about 30 degrees. After this happened the warning always comes back and the cruise shuts off after starting the engine and driving a minute or two. The steering wheel has remained at the angled position when driving straight.
