That's not accurate. You don't need to upgrade the MCU/infotainment computer and the retrofit is only $200.

"A source has informed me that due to AT&T shutting down its 3G network by Feb 2022, Model S's without an LTE-capable modem will lose connectivity features unless connected to WiFi. HOWEVER, Tesla will offer retrofits for $200. Affected vehicles are pre June 2015."

"Tesla will be offering retrofits for these vehicles for a bargain price of only $200, even though the vehicles affected by this could be up to nine years old."

See https://www.tesla.com/support/update-3g-services

They're going to upgrade the modems to LTE for $200 each.

I really appreciate my 2011 Civic's lack of a cellular modem.

Do you? Because when it's -10F here, I can remote start my car, even if outside remote start range. Rather nice to always have a toasty car (or cool in summer).

Ditto with our 2003 Citroën. This always online paradigm will cause more and more problems down the road, as the first IoT generations lose Internet access.

Okay that's good. Last I heard was that they stopped doing daughter board upgrades, and you had to swap your entire computer. Things like this tend to change pretty fast/often in Tesla land, so can't always keep up.

(Also don't have a 2014 Model S so doesn't impact me personally)
