NHTSA Complaint #11427176 — 2018 RAM 2500

The DEF Pump responsible for controlling the flow of Diesel Exhaust Fluid to reduce exhaust emissions prematurely fails (in my case, it was at 61,000 miles) which forces the truck into "limp mode" limiting the speed of the vehicle to 5 miles per hour. Additionally, once this part fails, the truck cannot properly dispense DEF to the exhaust to reduce diesel emissions as designed and as mandated by the EPA. Manufacturer acknowledged failure of the part and began redesign and remanufacture of the DEF Pump prior to the Covid pandemic. Replacement part availability is sporadic at best. Further, repair of this component has not been covered by Federal emissions warranty or any extended warranty of the drivetrain, thus forcing a several thousand dollar repair on the consumer. Online search reveals thousands of other Ram truck owners who are experiencing the same issues as described here My vehicle has been appropriately maintained and yet this occurred without warning of the imminent failure. Once the failure occurs, the vehicle poses significant risk to the environment due to inappropriate emissions, and places an undo financial burden on the consumer for a known manufacturing defect. I brought my vehicle to an authorized Ram dealership who diagnosed the issue as described above and then repaired the vehicle at a cost to me of approximately $ 2,100.00.
