Service bulletin ITB-13-037

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

CVT Variable Transmission (CVT) Class Action Owner Notification On March 23, 2022, the Court presiding over a class action lawsuit gave final approval to a proposed settlement under which the CVT warranty will be extended for the following vehicle: 2015-2018 QX60 Not including QX60 Hybrid model vehicles The approved settlement and the warranty extension are expected to become effective by June 1, 2022. Additional communication will be distributed prior to the warranty extension going into effect. To be clear, for the time being there is no warranty extension, and you should proceed with CVT-related claims as outlined below in bullet point three (3) under What Retailers Should Do. ** What Retailers Should Do *** 1. No action is necessary at this time. INFINITI will provide additional instructions prior to the effective date of the extended warranty, which is expected to be June 1, 2022. 2. If a client contacts the retailer with a CVT concern in an owned or leased vehicle, retailers should use the appropriate Technical Service Bulletin (TSB) to diagnose the root cause of the client concern and identify the correct repair to resolve the client concerns. NOTE: Retailers will need to follow the warranty process and obtain pre-approval from the Powertrain Call Center (800-973-9992 Option 2) for any vehicles requiring CVT assemblies to be replaced. Valve bodies and CVT belt and pulley kits do not require pre-authorization. 3. If the vehicle is no longer covered by a powertrain or parts warranty, provide owners a repair estimate for test drive, diagnosis, and repair after consulting the Goodwill rental guidelines available in the Assurance Product Resources Manual (APRM) for detailed information regarding application of rental reimbursement.
