2026 Ram 3500 Vehicle speed control Problems

“Vehicle at dealership a third time for same issue relating to U1412 code associated with ABS system. First time it was towed on 1/19/2026 and second time I took it to the dealership before it required towing on 3/26/2026. This time the truck required towing again after not being able to go into gear or being able to turn it off. Multiple warning lights on the dash. Still waiting for diagnosis but service department knew this problem from other vehicles and said manufacturer isn’t sure of cause.”

“This is related to the 2025/2026 Ram 3500 U1412 code relating to anti lock brake system. On this date I got an ABS warning light and check engine light. The vehicle would not turn off, was not sure if it was in gear or not, and multiple other lights came on the dash. Vehicle towed to dealership. They said they could not reproduce the error and that all the codes disappeared due to the batteries dying overnight. They replaced both batteries and returned vehicle. Have since had same problem twice more with one requiring towing again. …”
