Tesla Model S vehicles without LTE-capable modem will lose connectivity features next year as AT&T shuts down 3G network

Tesla MCU upgrade

Some Tesla Model S vehicles will lose connectivity features early next year as AT&T has announced it will be shutting down its 3G network in February 2022.

The shutdown affects vehicles in both Canada and the US built before June 2015. Connectivity features will still be available when the vehicle is connected to a WiFi signal.

In an email sent to employees on Thursday, a copy of which was obtained by Drive Tesla, the automaker is encouraging Service Centers to proactively reach out to affected customers about the shutdown.

The good news is there is a retrofit available, and it is reasonably priced at just $245 CAD or $200 USD. According to the email the retrofit can be completed in less than one day so long as the Service Center has the required parts on hand.

Pre-June 2015 Model S vehicles that have already received the MCU2 upgrade will not be impacted and do not need to purchase the upgrade.
