I have a 2015 Dodge Ram 1500 ecodiesel. The DEF distemper line has plugged up again. The flex exhaust has blown out on the bottom and has caused a leakage on the bottom, we can not get parts. I've heard of recalls concerning the DEF and exhaust system but am hitting walls when it come to repairing this truck. I just had it in the ship in December, $1200 later and just under 1000 miles the service light comes in saying truck will not restart in 200 miles. Had very similar problem in December. Does anyone know a way around this or how to get parts for this problem? I've spoken with several diesel mechanics and I'm being told Canada has stopped shipping the part needed. I've also been told to wipe out the entire DEF system. Suggestions and any help would be greatly appreciated as I am completely lost. Only had the truck since mid November. So yes, drove about 3 weeks = break down #1. Took to shop, drove a few weeks = break down #2
