   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. In May 2026, the vehicle was returned to the dealer for the ongoing mirror issue; however, the service notes only indicated that a part adjustment was performed, and the defect persisted. The contact then took the vehicle to a second dealer to repair the digital mirror and address the DEF system, as the warning light had re-illuminated on the instrument panel. During this visit, the second dealer performed a recall repair under NHTSA Campaign Number: 26V059000 (Exterior Lighting, Electrical System). While the dealer claimed to have serviced both the DEF warning light and the mirror, the mirror failure remained unresolved. After spending a cumulative month at the dealer, the vehicle was diagnosed with an illuminated check engine light caused by a recurring DEF-contaminated fuel leak. The dealer replaced the entire DEF assembly, including the fuel system components, and cleared the DTCs. In July 2026, the vehicle was returned to the dealer yet again for another digital mirror replacement, which failed to resolve the issue. The contact believed there was an inherent manufacturing flaw at the top of the fuel tank causing the repeated DEF system failures. The vehicle was not repaired.

3. Filed Aug 25, 2026Failure Jun 6, 2025Burleson, TXElectrical system, Service brakes, Vehicle speed control

   When driving the Anti lock brakes, cruise control, front and rear collision warning system, automatic emergency breaking system and lane keeping system are disabled. All of these alerts are displayed on the display cluster. All of these systems are disabled at the same time. I was told by the dealership that this is caused by a faulty Wheel Speed Sensor. The Wheel Speed Sensors have been replaced 3 times and have not fixed this problem. This has happened when towing a 14,000lbs trailer and the stability of the truck and load are compromised when breaking with a load.

   I have been submitting reports to you for several months with no resolution. The truck yet again experienced the same problem, twice, within 1 week. It would start but then claim that it couldn't detect what gear it was in and said "can't shut off until transmission is in park". After cutting electrical power to get it to shut off, it would not start. After getting it started, it would not go into gear. Once I got the engine running and transmission to go into gear, it no longer had ABS.

   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.

   From the first day i bought the truck i noticed it had a very tight vibration coming from the rear. I thought its may just be the Firestone tires that were put on at the factory. I had to drive out of state to a small town in Nevada. After around 3500 miles the vibration became severe and felt like i had a tire seperating. I called the nearest tire centers/shops within about 100 miles of my location. None carried the firestone transforce tires. So i traveled to the Nearest shop around 60 miles and the certified tech and managed assisted me. The did an inspection and found the tire was scalloped and damaged. Due to the size difference in the tires the shop had available, i had to purchase 4 tires they had in stock. When the tech and manager roadforced the wheels and tires he discovered one of the wheels had a defect and was not actually round and had a slight “out of round” defect starting from the hub mount center bead that extended to the outer circumference causing the rim”wheel” to be out of round which is how the tire was severely damaged. An out of round wheel can cause tire failure and thus, a safety issue. To date as i write this report, i have tried twice with a dealership to try to resolve this issue under the warranty.

   There have been a couple of instances where the running boards haven’t deployed when the door has been opened. The most recent caused my 10yr old to FALL OUT IF THE TRUCK and get injured. I believe the combination that is causing it is to get in the truck, hit acc and get I’ll all windows down. Then turn off the acc and stay seated in the truck for some time. Then open the door from inside and they don’t deploy…

    My ram truck will intermittently have a Christmas tree of warning lights on the instrument cluster, which occur while driving. During these periods, I do not have access to four-wheel-drive, accident avoidance, antilock brakes, etc. If I continue driving the truck for the remainder of the day, the lights will usually go off, but will be stored in the vehicles PCM. the dealership has previously evaluated this and reports that they cannot fix or evaluate the vehicle because there is not an active warning light when I bring it to the dealership. However, when these lights occur, I could be towing a heavy trailer and have no access to the truck safety systems until the lights correct itself. This has occurred more than once. I do not take photos of the lights each time. The photo included is only one of the times. The last time I believe this occurred was on 1/29/2026. Each episode are the exact same warning lights.

    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. While at the dealership they reported to me that it developed additional issues and would not shift into gear. It is still at the dealership in Pine Bluff AR.

    While driving with a trailer after leaving a jobsite in [XXX] , 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. A sudden loss of instrument display, lighting systems, and electrical functionality while towing creates a major safety concern for both the occupants of the vehicle and surrounding traffic. The failure appeared intermittent because the vehicle resumed operation after sitting for a period of time. However, the incident involved complete loss of critical vehicle display and lighting systems while driving. The vehicle is available for inspection upon request.

    I received notification of a safety recall on my 2025 Ram 3500 (NHTSA Recall Number26V-059) which affects the trailer lights and braking system. I contacted my dealership to schedule the repair and was told that it would be about 6+ months before they could get to me. The dealership has 30+ trucks on their lot, and the manufacturer is only allowing them to order 1 replacement part per week, so they aren't fixing sold trucks until those 30+ unsold trucks are fixed, which will take 30+ weeks. I'm submitting this online complaint because I tow a large trailer regularly and I don't feel that 6+ months is an appropriate time period for fixing a recall and I don't think that fixing unsold trucks should take priority over fixing trucks that are actively being driven every day.
