Service bulletins for the 2015 Infiniti Q70

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.

EXPIRATION NOTIF2021-01-08. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT. Expiration Notification - 2G Telematics Hardware Replacement Campaign Summary In 2016, INFINITI launched a Client Satisfaction Initiative (CSI) that provided clients with an opportunity to update the Telematics Control Unit (TCU) in vehicles equipped with a TCU designed to connect to the 2G cellular network. AT&T stopped accepting enrollments on the 2G cellular network, and discontinued its 2G cellular network coverage on December 31, 2016. Once the 2G cellular network was discontinued, there was no access to the INFINITI Connection features without a TCU hardware upgrade. Because AT&T will shut down its 3G network on December 31, 2021, INFINITI is discontinuing this Client Satisfaction Initiative to upgrade from 2G to 3G compatible hardware effective immediately. 3G services will continue to be provided until December 31, 2021. Vehicles equipped with a TCU that connects to the 3G cellular network will have no access to the INFINITI Connection features, including Emergency Calling and Automatic Collision Notification after that time. What Retailers Should Do Service Comm will deactivate PC451, PC452 and PC454 on any VINs on December 22, 2020. No further retailer action is required.
