NHTSA Complaint #11608046 — 2022 MERCEDES-BENZ SPRINTER 2500

The engine fan fell off, broke off, sheered off at the bolt that attaches it to the engine. The van is brand new this happened with less then 3000 miles on it. We realized an issued when the van gave a warning to stop immediately and turn off engine. This warning came on 3-4 times as we tried to ascend the pass. We had not place to go on this road. We pulled off several times waiting and hour to let it cool just to travel 3 miles.We just thought we may be running to hot. It was warm out, on an incline on Logans Pass in Glacier national park. Once we coasted out of the park after several hours of this situation and were able to safely get under and look we discovered the fan was dangling in the engine compartment. We contacted a dealer in Billings who told us they have seen several of these. We have read several sprinter van forums and Facebook pages where numerous people are reporting the same issue. The Missoula Mercedes Benz dealer replace the pully, the belt and the fan. The said they were going to replace the water pump, but did not. We requested the parts from them and they would not allow us to have them. We requested pictures of the parts and they still have not been supplied to us. We have a few pictures of the damaged bolt. The service tech was initially just going to rethread the bolt. This a know problem by Mercedes Benz, Winnebago and they are taking no measures to correct it. Repaired it putting the same parts back on. What is to ensure this will not happen again. We were in a remote area of Northern Montana with limited service. We were essentially stranded there for three days.
