DEF fluid pump

[Mikeyatc]

Hi there, I'm a new member here. I bought a new 2014 Cummins 3500 long bed last June. A few weeks ago I got a Check engine light. Turns out it was the DEF fluid pump. Dealer put a new one in and it quit on the way home. Has anyone had issues with the DEF pump? thanks mike

We've seen some issues with the DEF pumps, there was a flash update to correct some DTC's that were being set, but it didn't fix all the issues. I've replaced a couple at work, it's not super common but I've seen a few issues here and there. Have to remember the DEF systems are still very new in the light duty automotive world, there's going to be some teething issues.
