While maintaining momentum on a winding road, the vehicle's automated systems falsely intervened, aggressively pulling the steering wheel and forcing the vehicle toward the edge of a cliff. The sensation mirrored violent torque steer, fighting driver input and nearly causing a catastrophic departure from the roadway.Safety Risk: This VIN is currently unlisted for active campaigns, but it is exhibiting the exact life-threatening failure mode detailed in NHTSA Campaign 26V316000 (FCA software defect). The manufacturer's current recall scope is inadequate and must be expanded immediately to include this VIN sequence before an uncommanded steering event results in a fatal crash.
