4 times in less than 4000 miles my 2026 trucks abs, cruise control, skid control, and check engine warnin07g lights have come on. I then have no anti-lock system, no cruise control, no 4-wheel drive, and no anti-skid system. Code reads-U1412. The dealer has replaced the rear speed sensors and it continues to happen. My truck is currently at the dealer in the service bay as I can't drive it. I've researched this and it's happened to many who have purchased this truck.
The contact owns a 2026 Ram 3500. The contact stated that while driving at an undisclosed speed, the ABS and several unknown warning lights were illuminated. The message "DANGER" warning light flashed repeatedly and extremely fast on the instrument panel. The vehicle was taken to the dealer, where it was diagnosed, and determined that an unknown software update was needed. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer. An engineer inspected the vehicle; however, the cause of the failure was not determined. The vehicle was not repaired. The contact referenced a recall with a similar failure; however, the VIN was not associated with a recall related to the failure. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was unknown.
Trucks DEF Gauge malfunctioning goes from full, to half, to full, to empty, and then warns about going into limp mode. Filled with DEF and still doing it. Took in for repairs, company said they fixed it, but within 3 miles gauge was doing the same thing. This is a hazard as it will put the truck in limp mode. Known issue with many complaints, needs fixed
Trucks Navigation and GPS stopped working. Took to dealer for repairs, could not replicate the issue. They brought the truck back to me, and upon starting it the GPS/Navigation is not working. Other than the navigation, more systems work off the gps and needs to be functioning. Have multiple videos of nav not working, and dealer still stated that wasn't enough to determine there was an issue.
