Selected complaints filed with NHTSA by 2025 Ram 3500 owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2025 Ram 3500. The contact received notification of NHTSA Campaign Number: 26V059000 (EXTERIOR LIGHTING, ELECTRICAL SYSTEM). The contact noticed the failure on the drive back after the vehicle was purchased. The contact stated that on a separate occasion, while driving at an undisclosed speed, the brake lights and turn signals failed to function as intended. The contact lived in a rural area and stated that at night it is dark, and the brake lights nor the turn signals were operable. The contact felt that the vehicle was unsafe to drive. The local dealer was contacted, and the contact was informed that the parts for the recall repair were available. However, the parts were allocated to unsold vehicles first, and there was no estimated time for the recall part to be available. …
The contact owns a 2025 Ram 3500. The contact stated that the front passenger's side, rear passenger's side, and driver's side seat belt reminder (SBR) system was inoperable. There was no warning light illuminated. The vehicle was taken to the dealer, where a third-party engineer diagnosed the vehicle and determined that the vehicle was only designed with a front driver's seat belt reminder (SBR). The manufacturer later informed the contact that Ram engineers had confirmed that the vehicle was operating as designed. The vehicle was not repaired. The failure mileage was approximately 18.
While driving with a trailer after leaving a jobsite in [redacted] , the vehicle experienced a sudden electrical failure while in motion. The instrument cluster/speedometer screen went completely black and the vehicle lights stopped functioning properly while driving at night. During the incident, we lost the speedometer display and visibility from the vehicle lighting system, creating a serious safety hazard while towing a trailer on public roads. Because of the electrical failure, we were forced to pull off on the side of the road to avoid a potentially dangerous situation. After shutting the truck down and waiting approximately one hour, the vehicle was restarted and the systems eventually began functioning again. This vehicle is used regularly for commercial towing and jobsite operations. …
The contact owns a 2025 Ram 3500. The contact stated that shortly after purchasing the vehicle brand new and filling the fuel tank on December 3, 2025, the DEF depth gauge failed. The vehicle was taken to a dealer, where the module was reprogrammed and the physical gauge was replaced. However, the contact obtained internal service notes revealing that the urea pump, the DEF tank, the urea tank wiring harness, the DEF injector, and the fluid had actually been replaced due to an active fuel leak within the DEF system. On March 31, 2026, the vehicle was taken back to the dealer to address a malfunctioning digital rearview mirror. While at the dealer, a recall repair was performed under NHTSA Campaign Number: 25V882000 (Air Bags, Electronic Stability Control (ESC)). The digital mirror was replaced; however, the failure recurred immediately. …
Brand new truck (497 miles) while driving on freeway at 70 mph, truck kicked out of cruise control and threw traction control, adaptive cruise control, 4wd, check engine, and anti lock brakes disabled fault lights and codes. The vehicle will disable all these safety features for 30-50 miles, and then the faults will randomly disappear except for the check engine light. This has happened 10-12 times. This truck has had 4-5 "ram cares" case numbers, has been at the dealership for over a month combined. The faulty part supposedly is a right rear wheel speed sensor on the 12" dually axles. There is hundreds if not thousands of these trucks affected. Stellantis/ram says the sensor is has been updated, but is currently not built or for sale., there is a national backorder. We are being told to drive these trucks while ram comes up with a fix. …
The truck had about 7400 miles on it. It gave a warning that the DPF was near full and take it to dealer, about 20 minutes late it said DPF full power reduced. Two days later it cleared that code and began flashing the turn signal intermittently and giving warnings that the trailer brakes were not working, then that the tailgate was down. Shortly after that the instrument cluster went completely blank. I was driving it to the dealer when it ran out of fuel and forced me to stop on the highway. The vehicle has been at the dealer for almost 4 months now. When they replaced the dash cluster it would take too long to start. They replaced multiple modules and I believe three dash clusters before declaring it repaired. I picked it up for a test drive and the frontal collision warning came on intermittently along with a warning that automatic wipers would not work. I took it back. …
The 2025 and 2026 dually 3500 Ram trucks with the 12" AAM rear axle are having issues with the rear wheel speed sensors (different sensor for each side). They apparently fail or are not able to properly communicate to the computer. When this happens, the following are disabled: -ABS -Auto Emergency Braking -4x4 -Electronic Stability Control -Cruise Sometimes, the engine won't shut off. The gauge cluster will state it can't detect which position the transmission is in. So, you cannot shift, and you can't shut the truck off, and you can't drive. You are stuck in place with a running engine. Despite Stellantis releasing a new revision of wheel speed sensors (AB revision), they have failed in less than 2,000 miles on my truck. Many, many dually owners are experiencing these failures. I've had this problem occur over half a dozen times. …
