While driving on interstate leaving a construction zone started to accelerate to maybe 40mph and heard/felt a hard clang and lost all forward motion costed to side of interstate. Looked underneath truck, nothing visible broken or leaking. Restarted truck tried to move forward with no luck. Reverse worked, put back in drive loud noise again stomped on the accelerator and started moving forward very slow and difficult. Made it to an exit to look at things in a safer location than the busy interstate. Figured out that I had reverse and 5th gear so it was very hard/ slow to get moving. Check engine light on, gear ration incorrect, code P0731, Tran sensor failure, no 4x4 Transmission failure 1-4 gears not working

The contact owns a 2022 Ram 3500. The contact stated that while driving at an undisclosed speed and attempting to accelerate, the electric power steering was not functioning properly, requiring an increased effort to maneuver the vehicle. The contact was able to pull over to the shoulder of the roadway, where the vehicle returned to normal functionality, but the failure became a regular occurrence. No warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the wiring harness connector due to water intrusion, resulting in damages to the electric power steering control module. The contact was informed that the connector seal had failed to prevent the entrance of water leading to water damage. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 20,000.

The transmission in my vehicle failed suddenly on May 31, 2025, entering “limp mode” and losing the ability to shift properly. The vehicle became immobile and was towed to the dealership. Initial diagnostics revealed difficulty shifting between 3rd and 4th gears. Service technicians attempted repair in June based on RAM TSB MC-10231775, which indicated snap ring failure in the Aisin transmission. Repairs prescribed in TSB were attempted but unsuccessful, as the vehicle still could not shift into 4th gear. Additional parts were ordered, and another repair was unsuccessfully attempted in late June. Ram has shipped a new transmission which we are waiting on the dealership to install.

Fuel/propulsion System

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 cha...
