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
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 2025 and 2026 dually 3500 Ram trucks with the 12" AAM rear axle are having issues with the rear wheel speed sensors (different sensor for each side). They apparently fail or are not able to properly communicate to the computer. When this happens, the following are disabled: -ABS -Auto Emergency Braking -4x4 -Electronic Stability Control -Cruise Sometimes, the engine won't shut off. The gauge cluster will state it can't detect which position the transmission is in. So, you cannot shift, and you can't shut the truck off, and you can't drive. You are stuck in place with a running engine. Despite Stellantis releasing a new revision of wheel speed sensors (AB revision), they have failed in less than 2,000 miles on my truck. Many, many dually owners are experiencing these failures. I've had this problem occur over half a dozen times. …

The transmission spontaneously slipped out of park and went into reverse. My safety was close to critically impacted. When it began to roll on its own, I was scooped by the driver door and dragged several yards until the truck impacted another vehicle and came to a stop. I very likely could have been killed. If anyone had been behind the truck they likely could have been killed. The incident resulted in significant damage to my vehicle and the vehicle that it ran into. I have not driven the truck since the incident to reproduce. Police did come out to inspect the accident. Has not gone to dealer yet. There were no warning light, buzzers, etc. completely spontaneous. Note: the vehicle was running when this happened. When I was able to get back in truck the stalk was still in park position
Driver of the 2022 Ram 3500 pulled out of a driveway onto a street and ran over a pedestrian who was crossing in front of him. Driver states he did not see the pedestrian. I understand the 2022 Ram 3500 is equipped with front ParkSense Sensors, but these sensors failed to deploy. The pedestrian suffered very serious injuries requiring weeks of hospitalization and additional outpatient rehabilitation. The incident is caught on surveillance camera. The vehicle should be available for inspection upon request. The vehicle has not been inspected.
