  1. Filed Mar 9, 2024Failure Sep 8, 2023Mount Vernon,, WAFuel/propulsion system

    My 2021 Chevy 4500 is an RV, anyway last September 2023. 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. I had just made it off the freeway by a few feet, I seriously thought we were going to get rear ended, especially by a truck because a majority were not moving over. They were rocking our RV as they passed us. The RV ended up starting and running good not stalling again, but it was at times difficult to start. We ended up taking it home to Mount Vernon, Washington to get it repaired. It was still under warranty, although the battery wasn't. I thought at first it was a fuel problem, but after getting it scanned it was a fuel pump problem then after the fuel pump was replaced, they said it was also the fuel Modulator. I had to wait for 4 and 1/2 months to get this replaced. meanwhile my 2-year battery went dead while it was sitting there at Blade Chevrolet in Mount Vernon, Washington and there was no pro-rate on it so I was stuck for the full price of the battery. At the time of this repair, I had about 11,878 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

    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.

  3. Filed Jun 10, 2022Failure May 25, 2022Kingston, TNPower train

    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.
