2025 RAM 3500 Problems

3 times to date (10,000 miles/8 months) I have failing abs speed sensors. If I stop moving when all lights come on dash the truck is in operational. I cannot shift gears, put in park or turn engine off. Loose traction control, ads, 4wd, stabiltrac, speedometer. All assitive and braking functions. Code U1412. Dealer replaces speed sensors but problem returns.

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…

Recall 26V-059 Brake lights and brakes don’t work sometimes. Dealer has no parts. Will not tell me when parts are coming. This is a serious issue and I need it fixed. It should not take this long.

Trailer Brake Module recall was completed. Now getting random error messages and lights advising trailer disconnected, etc. even without a trailer being hooked to the truck.

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.

The contact owns a 2025 Ram 3500. The contact stated that while driving approximately 60 MPH, several unknown warning lights illuminated, and the vehicle stalled. The vehicle was towed to a dealer where it was diagnosed, and determined that several repairs were needed, and there was an issue with the battery. The dealer replaced two batteries, but the failure persisted. The vehicle was taken back to the same dealer, but the cause of the failure was not duplicated. On another occasion, while driving approximately 50 MPH and hauling a trailer, there were several unknown warning lights illuminated, and the contact heard a loud banging coming from the engine compartment before the vehicle stalled. The vehicle was towed to a different dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 9,000.

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. It has been to the dealership to be repaired 3 times so far. After the 2nd time at the dealership, the sensors only last less than 23 miles.

The contact owns a 2025 Ram 3500. The contact received a recall notification of NHTSA Campaign Number: 26V059000 (Exterior Lighting, Electrical System); however, when the local dealer was contacted, the contact was informed that the manufacturer was shipping a very limited number of parts to dealers for the repair. The manufacturer was contacted, and the contact was informed that the dealer should request an expedited shipment. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The vehicle was not repaired. The contact had not experienced a failure.

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.

While driving my truck under normal conditions and using the turn signals as expected, I noticed an issue after parking in my driveway. The turn signals began activating automatically without any driver input, alternating from left to right approximately every 5 seconds. The behavior stopped once I manually engaged the turn signal lever. My truck is one year old - Video Link [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
