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…

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.

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…

2026 Ram 3500 with <2700 miles. The trailer brakes are not applied appropriately when using the brake pedal, even though it will brake appropriately (with 1 of 3 trailers) while squeezing the manual override. This includes all brake levels (1-10 gain). When the trailer is disconnected, the truck will brake and show the appropriate level of pressure on the dash, though when the trailers are connected, one might press their foot 50% of the way down on the pedal while only 5% of the pressure is displayed on the dash and applied to the trailer brakes. This has nearly caused 3 separate accidents while towing (16,600 pounds total) when people merged and braked hard in traffic. Ram dealership…
