2026 RAM 3500 Problems

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.

ONLY 1,800 MI. I continue to experience ongoing issues with this truck, despite having just received it back from the dealership two weeks ago following repairs related to a rear pinon gear. the truck is now back in the service department for concerns involving the front differential. Given the repeated drivetrain issues, I am increasingly concerned about the safety and reliability of this vehicle, particularly the possibility of a catastrophic mechanical failure while traveling at highway speeds that could result in loss of control. These ongoing problems have significantly undermined my confidence in the vehicle's safety and dependability. At this point, I am concerned not only about the continued mechanical problems but also about the potential risks to my safety and the safety of others on the road. I believe these concerns warrant serious attention and a resolution as soon as possible.

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.

Brand new 2026 Ram 3500 Limited Truck. Front parking sensors goes off when something is 15-25 feet away. Very frustrating as I have to turn off the front parking sensors. Had the same issue on my 2025 Ram 2500. Also, the tailgate is misaligned from the factory. Currently my truck is at the dealership, and they don't know how to realign the tailgate. No fixed. Again very frustrating on a brand-new truck from Ram.

The vehicle was taken to the dealer, who replaced the speed sensor for the rear wheels; however, the failure persisted, and the transmission failed to recognize that the gear selector was in park(P). Roadside Assistance arrived and unplugged the battery cables to turn off the engine. The vehicle was towed to the dealer and was waiting for engineers to diagnose the vehicle. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 458.

The contact received notification of NHTSA Campaign Number: 26V059000 (EXTERIOR LIGHTING, ELECTRICAL SYSTEM); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact called a dealer while traveling in Braunfels, Texas, and asked about parts availability. The dealer stated that the manufacturer was providing only one part per week to the dealer location, which was causing a long wait for the recall repair. A second dealer, Miller Motor Sales Chrysler Dodge Jeep Ram (1196 Milwaukee Ave, Burlington, WI 53105) was contacted and confirmed the limited part supply to the dealer. The manufacturer was not made aware of the issue. The contact had not experienced a failure.
