2026 Ram 3500Recalls, problems, MPG & safety

“Failed systems: Failed calibration of speed odometer, Tire pressure Monitoring System, Adaptive Cruise Control, Crash Avoidance System. Brakes, Electrical. Vehicle purchased 3/30/26 with multiple repair attempts by dealership including replacing TPMS module, ECM Module, and Trailering Module. 3 episodes of vehicle rolling backwards and breaks not working while on incline with most recent 11/2/26 resulting in catastrophic brake and electrical failure during which the vehicle rolled backwards crashing into tree. 1 episode of vehicle locking up while going down interstate at 70 MPH with loaded trailer attached. This places the driver and passengers at risk for injury and/or death. Per the dealership, they have not been able to reproduce the issues but stated that it is unrepairable. No manufacturer inspection has been completed. Warning lights and warning messages have been present since before first return to dealership on 4/9/26, 6 days after purchase of vehicle, for TPMS issues, inaccurate speed odometer, and incorrect lift kit installation.”

“On multiple occasions the U-Connect system in the listed 2026 RAM 3500 has gone completely black and was inoperable until a reset was performed. The trailer brake gain control and exhaust brake are accessed and controlled via the touch screen U-Connect system. This failure poses a significant safety issue when the screen goes black and the controls cannot be accessed when pulling a trailer. This can lead to failure to slow/stop the vehicle while in motion, tire failure on the trailer etc. The only method to regain access to the brake controls is to perform a reset of the U-Connect system which can take 2-3 minutes to complete. Stelantis is and has been aware of this issue for some time and has no resolution at this time.”

“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”
