Service bulletin ITB-12-044

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.

PC501 - 2013 JX3	2017-08-01. Service bulletin. CVT Software Update/Warranty Extension Voluntary Service Campaign *** Campaign Summary *** Infiniti is conducting a Voluntary Service Campaign to reprogram the Transmission Control Module (TCM) to improve CVT service diagnostics. This diagnostic software update will enhance the retailer's ability to diagnose client concerns regarding Continuously Variable Transmission (CVT) operation; it does not repair any symptoms nor alter the drive characteristics of the vehicle. Specifically, the diagnostic logic will store two new Diagnostic Trouble Codes when "Judder" symptoms occur on vehicles. - P17F0 - "Judder" caused by belt slip - PF171 - "Judder" caused by control valve In addition to the installation of diagnostic software, Infiniti will also extend the warranty coverage on the CVT assembly (including internal CVT components, gaskets, and seals), CVT control valve body, and torque converter from its original duration of 72 months/70,000 miles to 96 months/94,000 miles (whichever occurs first). Coverage of other vehicle components remains unchanged, and all other terms, conditions, limitations and exclusions of Infiniti's New Vehicle Limited Warranty continue to apply. This CVT warranty extension is being provided as a client satisfaction effort to address client concerns; including those concerns expressed by plaintiffs in class action litigation, and is subject to final approval of the settlement of that litigation. In the interim, Infiniti will make any necessary repairs that would be covered under the extended CVT warranty.
