The contact owns a 2026 Ram 3500.

Hello, I am formally documenting a serious safety incident involving my recently purchased 2026 Dodge Ram 3500 Tradesman 6.7L dually, purchased from Towbin Dodge in [XXX] , on May 9, 2026. On May 13, 2026—only five days after purchase—we were operating the truck for our dumpster business while towing a GN trailer loaded with approximately 5 tons. We were traveling down Mount Charleston after a pickup when a critical brake failure occurred. While descending the mountain grade, the truck’s braking system failed to respond. A warning light appeared on the dashboard indicating an issue with the electric brake system. We had tow/haul mode and exhaust braking engaged, but neither system functioned properly. When my father pressed the brake pedal, the vehicle did not slow down. With a steep descent ahead and no effective braking response, my father was forced to steer the vehicle off the road into a ditch to avoid a direct impact with the mountain, which could have resulted in a fatal col...

Vehicle sends cluster warnings about Auto Emergency Braking unavailable/inoperable, Electronic Stability Control needs service, Antilock Brake System needs service, Parksense Unavailable, and ultimately the Check Engine indicator illuminates after restarting the vehicle. An error code also is present in the computer, U1412. This has happened twice now in a two week period. These systems are critical to safe operation of he vehicle, especially in emergency braking conditions, and could affect both the operator and the general public if they indeed failed. The vehicle has not been inspected by the manufacturer, yet, and is scheduled for 5/8/2026

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. If this problem happens on roadway while being operated it would be very dangerous on roadway.
