2021 HO 3500 threw a code requiring the DPF to be replaced. My truck is sitting at a dealership for a month now waiting on the part. It was initially said to be on backorder with a delivery of 2 weeks. 2 weeks went by, no part. They said another 7-10 days...still not part. Now, they say on another 7-10 days again for the expected delivery, yet no tracking information etc. The problem is that it happened up in MA, and I live in FL. I compete around the country with my horses. I was up north, and just about to leave for FL with the horses when the truck broke down. So I sit here in now freezing temps, living in the camper part of my trailer, paying additional rent for stabling of the horses, and no clue when I can leave. They never gave me a rental because they said they don't have a comparable model. I'm stranded, horses are cold, and my water lines are starting to freeze up. Has anyone recently received a DPF? It seems some online parts stores claim to have them in stock. Dealership is trying to tell me that they aren't available anywhere. I understand this part is in high demand recently, but my truck is labeled "off road " and still nothing is happening. Stellantis has a case but they won't answer or return my calls after the 1st inquiry. The man said it was shipping out and he would get me the tracking, but its been crickets.
