I started my Sprinter, which was converted into a Grech RV, and while still in park a few seconds later, the vehicle started to move. Before I could hop back in the driver's seat to stop the vehicle, it crashed into my garage overhang and significantly damaged my Sprinter's back doors and back structure. How it started to move was a complete mystery to me as it was in park and I had just started the vehicle a few seconds prior. While doing some research, I saw an article in an auto blog forum about Sprinter Van roll-aways. I then received a safety recall notice from Mercedes about this very issue that I experienced. This involves NHTSA Recall #22V796. The incident was reported to my insurance company and the vehicle is currently awaiting repair. Thankfully, no one was injured.
