Remedy: Dealers will install new labels, free of charge. Additionally, Nissan will mail replacement labels to owners. Interim letters notifying owners of the safety risk were mailed September 2, 2026. Additional letters will be sent once the final remedy is available, anticipated Fall 2026. Owners may contact Nissan customer service at 1-800-867-7669. Nissan's numbers for this recall are R26B1 and P6A13/4.
