I initiated a turn and the steering wheel suddenly and forcefully moved in the opposite direction of my steering input. The steering wheel was pulled out of my hand. I was unable to maintain the intended steering direction and the vehicle was involved in a collision. This was not an intentional steering maneuver or ordinary loss of traction.

Electrical system shutdown including loss of all safety features (blind spot, emergency braking, abs, traction control, towing), climate control options (AC, Heat, window operations) and user interfaces (U-Connect screen, center gauge cluster). Initial warnings (2) on center cluster on listed- 1. Blind Spot Detection Disabled 2. 115 Volt Cargo Power Outlet On All electronics, controls were then disabled- black screens, inoperable controls. Passenger rear windows, sliding back glass, panoramic sunroof and drivers side mirror are the only working electronics other than speedometer. Upon inspection of all fuses, relays, battery, alternator, and checking all accessible wiring related to blind spot and auxiliary power and finding no defective issues, web searches were performed. Based on numerous other RAM owners on multiple forums on RAM trucks 2020 and newer with blind spot avoidance, we found a likely culprit in the driver's side brake light. Upon inspection of the left rear brake light assembly, a small hairline crack was located with signs of internal moisture/ condensation. After observing the internal moisture the drivers side rear brake housing was removed and disconnected for closer inspection and potential repair. While the driver side brake light assembly was removed, an instance occurred when my wife needed the vehicle. Upon and during the entirety of operation over the next 1.5 hrs driving approximately 63 miles, all electrical options worked as intended minus the blind spot avoidance and a new warning on brake lamps (obvious as tail light had been removed). During this time, the proximity sensor housing was removed from the assembly, water accumulation dried, and allowed to remain open next to a dehumidifier for 4 hours. Epoxy was applied over the hairline Crack, and any area that looked as if could be affected. Unit was reinstalled, however all electronic failure returned. Unit removed again to attempt humidity removal- all electronics res

In early October 2025, my 2021 RAM 1500 experienced a steering malfunction in which the vehicle attempted to steer on its own without driver input. This created a loss-of-control scenario and posed a serious safety risk to me and surrounding traffic. The vehicle was removed from service immediately and taken to an authorized RAM dealer. Stellantis Customer Care and Fleet Case Management have acknowledged the defect and identified a required replacement part; however, the part has been on national backorder since October 2025. As of December 31, 2025, the vehicle has been out of service for over three months. Stellantis has provided at least ten different estimated repair dates, all of which have passed without resolution. Despite the steering-related nature of the failure, Stellantis has stated there is no active safety recall. The vehicle remains unrepaired due to the unavailability of the required steering-related component. I am concerned that this defect may affect other vehicles and that the prolonged inability to repair a known steering failure presents an ongoing public safety risk. I am submitting this complaint to request formal review of this issue and to document the safety implications of this unresolved steering defect.
