NHTSA complaint #11735863

Owner complaint summary

The failure involves the AWD drivetrain system, specifically the rear differential assembly and previously the electromagnetic AWD coupler. The vehicle developed significant shuddering and vibration during acceleration from a stop and while turning at low speeds. A Nissan dealership has confirmed metal contamination within the AWD system and recommended replacement of the rear differential. The vehicle has not yet been repaired and is available for inspection upon request. This condition creates unpredictable acceleration and hesitation, particularly when entering traffic or making turns. The vehicle does not respond consistently to throttle input, which poses a safety risk by limiting the driver’s ability to accelerate as expected and avoid potential hazards or collisions. The issue has been confirmed by both an independent mechanic and a Nissan dealership. The independent mechanic identified abnormal debris during fluid service and suspected a drivetrain issue. The dealership later confirmed excessive metal contamination in the AWD system. The vehicle has been inspected by an independent mechanic and a Nissan dealership. The manufacturer has not physically inspected the vehicle but has been contacted through Consumer Affairs. No warning lights or messages appeared. Symptoms began around November 2025 at approximately 80,000 miles and have progressively worsened.
