The motor of our vehicle failed while driving on the interstate. The vehicle is at a dealership for repairs and should be available for inspection. With little to no warning our truck quickly went from 70 MPH to completely shut down. We had to go from the left lane on the interstate to the shoulder. In the process we were very close to a collision. We were also hauling our camper (2023 Forest River R-Pod 153, which has a dry weight of 3,421 lbs and we had no water in our fresh/grey/or black tanks). When we merged into the right lane our truck was going so slowly on the interstate that we were almost hit and honked at before we could get to the shoulder safely. The problem was confirmed by the dealership that is working on it. The motor spun 4 rod bearings and it was a total motor failure. The vehicle was/is still under warranty. The manufacturer, I would assume, has inspected it as we are receiving a full motor replacement. That motor has been and continues to be on back order with no ETA for 2 months now. There were no warnings in how the truck was running. There were no warnings on the dash, warning lights, or any indication that our truck was going to break down.
