Have had five to six dealer visits and repairs due to DEF alert and limp mode issues. Replaced sensors, pump, catalytic converter on 2019 RAM 3500. Last time replaced nox sensors and was told all was well. Been using premium DEF fluid, keep it filled. After 2k miles with no alert decided to pull 30 ft trailer to Bend OR about 800 miles from home. No sooner got there when the DEF alert came on, made it to the Bend Dealer, said he could not help me for weeks but did read the code and deleted it. Said the limp mode may come on anyway so decided to head home hoping for the best. The reality was no dealer help, no loaner truck, no way to get my trailer home 800 miles away and no one to help me if i needed towing. Made it home sitting on the edge of my seat hoping DEF alert didn’t come on. Vacation was ruined. Think before you travel as who is going to help you if your truck craps out, dealers can’t help you, insurance will only tow to nearest service. SELLING THE RAM!
