NHTSA Complaint #11479478 — 2015 RAM 2500

My 2015 truck has 89,000 miles. The emission system DPF was replaced under EPA settlement with RAM at about 20,000miles. The DEF system failed at 89k. When it failed the truck started bellowing toxic ammonia from the exhaust. When the system failed, a check engine light came on and the truck indicated I had 150 miles before 5 MPH line mode. The amonia Fumes where overwhelming. You could see the cloud coming out of the exhaust. The dealer confirmed the DEF pump failed. However the pump is still working and pumped half a tank of DEF into my exhaust system in less than 30 miles. Independant shop suspects additional damage to NOX sensor and other parts as a result of the pump failure. Ram admits the pump is a high fail item but not covered past original 80k emissions warrenty. The pump is 1,400 dealer list. I have never heard of a vehicle having less than 100,000 10 year emissions warrenty. My VW TDI passat has over 150k full emissions warrenty from the EPA settlement. I don't understand how RAM is not liable for low milage emission failured below 100k miles. The pumps fail alot! Apparently they have been or are trying to redesign them. This is one leading reason why owners delete unreliable emission designs. I would like my emissions failure covered by RAM and the software logic updated on all RAMs to shut down DEF pumps when they fail so they do not produce heavy toxic ammonia clouds.
