Because AT&T will shut down its 3G network on December 31, 2021, Nissan is discontinuing this Customer 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 NissanConnect EV features, including Remote Charge Status Check, Remote Climate Control and Driving History after that time. What Dealers Should Do 1.Service Comm will deactivate PC449 and PC450 on any VINs on December 22, 2020. No further dealer action is required.
