Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Expiration Notification - 2G Telematics Hardware Replacement Campaign Summary In 2016, Nissan launched a Customer 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 NissanConnect features without a TCU hardware upgrade. 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.
What this bulletin may mean before buying
Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
