2022 RAM 3500 Complaints

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.

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.

Transmission failure while driving not allowing to go in park after we got stopped. Truck un operable to get out of traffic.

Trailer brake controler will report not connected when it is connected correctly. Systemm was tested and everything on the trailer is working properly. system was working corretly and suddenly stopped when on the interstate. Have had multiple shops look at the issue and no one can locate the issue. The radio/infotanment system will also disconnect radomly. Both act like a wire is lose. disconnect then reconnect and disconnect and reconnect, over and over. The radio disconnecting from the phone is an issue however not a safety concern like the trailer brake issue is. When I am pulling a 16,000 pound camper and the trailer brake stops that means I no longer have traler brakes and that can be an issue when stopping.
