NHTSA Complaint #11512417 — 2018 RAM 1500

The problem is with the whole DEF System in the truck. for the last 6 months I can't go a week or less without getting some kind of code. Every time it effects the electronic throttle control and the truck goes into limp mode, I can be going 70 mph and it drops down to 30-40 mph no matter where I am at. I have almost been rear ended several times. I fix that code and a week later another code pops up and we do it all over again. I think I may have gone 2 weeks without a problem in the last 6 months. This time it is the DPF and DEF system, and here we go back into limp mode. I have had it to the dealer last week for issues which they couldn't figure out but thought that reprogramming would fix. So I leave to go out of state to work and here we go again less than 100 miles from home. Exhaust filter is full with no regen for over 400 miles. Now I'm stuck out of state with this problem. I think this really needs to be addressed because after all of my research this seems to be a normal problem.
