Shortly after purchasing a new 2026 Ram 3500 in January 2026, the vehicle began displaying multiple safety warnings simultaneously while driving. Warning indicators included Check Engine, ABS, Brake, Traction Control, Electronic Stability Control, Forward Collision Warning, and Automatic Emergency Braking, along with a “Service Electronic Stability Control” message. The vehicle had very low mileage when the issue first occurred. The vehicle was taken to the dealership for diagnosis and repair. The dealership indicated the concern involved rear wheel speed sensor(s) and the vehicle’s electronic control systems (including a Body Control Module software update). Multiple repair attempts were required, including sensor replacement(s) and software updates, with manufacturer engineering involvement.

4 times in less than 4000 miles my 2026 trucks abs, cruise control, skid control, and check engine warnin07g lights have come on.
