NHTSA Complaint #11712897 — 2023 NISSAN ROGUE

During highway driving, my 2023 Nissan Rogue experienced sudden loss of power and entered limp mode without warning. Engine RPM surged abnormally, forward driving and collision avoidance sensors became disabled, and the vehicle could not accelerate properly. The fuel range also dropped rapidly during this event. This created a dangerous situation in traffic (I was in the mountains in Virginia) and placed me and other motorists at risk. The condition is intermittent and did not leave diagnostic codes. The vehicle was taken to a Nissan dealership, where recall repairs and ECM reprogramming were performed, but no root cause was identified and there is no assurance the problem will not recur. I am concerned this is a serious safety defect involving loss of propulsion and disabled safety systems.
