WBI/21-002	2025-10-21. Service bulletin. CAMPAIGN BULLETIN CVT Warranty Extension In an effort to assure customer satisfaction, demonstrate our confidence in continuously variable transmissions (CVTs), and to address customer concerns including those expressed by customers in a class action, Nissan will extend the warranty coverage on the CVT. The warranty extension includes the CVT assembly and internal CVT components, gaskets, and seals, CVT control valve body, torque converter, cooler kit (if applicable), Automatic Transmission Control Unit (ATCU) and reprogramming of the Transmission Control Module (TCM), on the vehicles listed in this announcement. The warranty is being extended from its original duration of 60 months/60,000 miles to 84 months/84,000 miles (whichever occurs first). Coverage of other vehicle components remains unchanged, and all other terms, conditions, limitations and exclusions of Nissan’s New Vehicle Limited Warranty continue to apply. *** What Dealers Should Do *** 1. If an owner contacts a dealer with a CVT concern in an owned or leased vehicle, verify warranty coverage for the specific VIN and then inform the customer of any diagnostic charges. NOTE: Some owners may have opted out of the warranty extension by excluding themselves from the class action settlement, thus it is important to check the VIN for each vehicle to verify coverage. 2. Use the appropriate Technical Service Bulletin (TSB) and/or Electronic Service Manual (ESM) to diagnose the root cause of the customer concern and identify the correct repair to resolve the customer concerns. NOTE: Dealers will need to follow the warranty process and obtain pre-approval using the VCAT tool. Please reference WBI/21-002. Control valves and CVT belt and pulley kits do not require pre-authorization for repairs made under warranty if they are within the dealer’s DCAL limit. 3. CVT warranty coverage can be confirmed using the warranty extensions/customer service initiatives page in Service Comm or DBS National Service History. 4. If the vehicle is no longer covered by a powertrain or parts warranty, provide owners a repair estimate for a test drive, diagnosis, and repair. If an owner requests assistance, be sure to consult goodwill guidelines available in the Assurance Products Resources Manual (APRM) section 2.2 and obtain the necessary approvals before proceeding.
