Open the full vehicle complaint log (all categories)The Deisel Exhaust Fluid (DEF), SUPPLY LINE (part #57008975AA) has been replaced on my truck 4 times in 113 k miles. It now needs replaced again. The last 2 times were less than 5000 miles each. It is a plastic line that runs from the DEF tank and passes nearby the exhaust filter which is very hot. A RAM dealer in Georgia told me they have sold/replaced many of these lines. When cracked, they leak DEF in large volumes on the ground which then becomes contaminated.
HIGH PRESSURE FUEL PUMP WENT OUT. I KNOW THEY HAD A RECALL ON THIS BEFORE. TRUCK IS DOWN AND IT WILL COST TO MUCH TO REPLACE FUEL SYSTEM
Transmission K1 snap ring failure. Left me stranded on busy road unable to move truck.Dealer has diagnost it. No warnings, just failed.
My 2022 RAM 3500 has repeated failures of the diesel particulate filter (DPF) system. The truck enters limp mode unexpectedly, including while towing on the interstate, creating a serious safety hazard due to sudden loss of power. Since purchasing the vehicle, I have experienced ongoing issues with the emissions system, specifically related to the DPF. The check engine light comes on frequently, and diagnostic scans consistently show code P2459 (Diesel Particulate Filter Regeneration Frequency Too High). The DPF system has been replaced approximately five times by authorized RAM dealer. Despite these repairs, the same problem continues to occur. The truck will sometimes enter limp mode without warning, drastically reducing engine power. This has happened while towing a camper on the interstate, making it difficult or impossible to maintain safe highway speeds or accelerate when needed. This puts me, my passengers, and other motorists at risk of a crash, particularly when merging or changing lanes in fast-moving traffic. I have already pursued and settled a claim with Stellantis (RAM’s manufacturer) for $10k due to these issues. However, the problem persists, and the root cause has not been resolved. Accepting the settlement was recommended by legal counsel. The failure has occurred on multiple occasions (at least five separate incidents). The vehicle has undergone several service visits and emissions system replacements, but the safety issue continues. Current mileage 42,000. Dates of incidents from most recent: 6/25 (still in shop), 3/25, 9/24, 8/24,7/24,6/24,4/24,1/24,7/23,6/23,11/22. Documentation available upon request. Diesel particulate filter (DPF) system replaced approximately five times. I believe there is a defect in the design or operation of the emissions system that poses a safety risk. Loss of power while driving at highway speeds or towing creates a dangerous situation. I am reporting this in hopes that NHTSA will investigate this recurring issue.
