All of my dash board light lit up. I stop the truck turn it off. when I get back in to drive it would not engage the transmission. No reverse No drive and the engine would not shut off. Happened about two weeks ago. the first time what in December, Same problem! they say it just needed a software flash, but if that was the case why would it happen again, and why would they need another software flash ?

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.

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.
