AT&T shuts down its 3G network Tuesday. Will it impact your car's navigation system?


Do you rely on your car's navigation, traffic or roadside assistance features? Then you may have woken up to an unpleasant surprise Tuesday as AT&T shuts down its 3G network .

While our smartphones stopped relying on 3G long ago, that's not the case for our vehicles' telematics systems , which capture a car's location, speed, idling time, harsh acceleration or braking, fuel consumption, vehicle faults and other data. That loss of GPS data means your car's built-in navigation system may stop working Tuesday.

And for all the drivers assuming they'll be fine because they drive a car built between 2020 and 2022, don't count on it. There are cars as new as 2021 on this list.

ALARMAGEDDON? Home security, medical device makers worry 3G is being shut down too soon sometime

There is some good news, however: Not everyone will experience vehicular Y2K on Tuesday.

Drivers who rely on Apple CarPlay or Android Auto for navigation won't be affected because those mirror the user's phone, which tends to use carriers' 4G, LTE or 5G networks. But it will be more important than ever to make sure you grab your phone before walking out the door in the morning. (Who hasn't left theirs at home at least once?)  And older cars whose navigation system runs off an SD card will also be spared.

Even if your car doesn't rely on AT&T, you still need to act sooner than later : T-Mobile will decommission the 3G network it inherited from Sprint on March 31 and unplug its own 3G on July 1. Verizon said it plans to decommission its 3G network by Dec. 31, 2022.

Cars affected by 3G shutdown

Here is the list of makes, models and years that will be affected:

GM (Buick, Cadillac, Chevrolet, GMC)

The 3G shutdown is generally expected to impact cars with OnStar made between 2015 and 2019 . Check GM's database to to learn whether your car is affected or if you can continue services via an over-the-air software update . You'll need your key code and VIN. Active, connected vehicles will receive free, over-the-air updates, according to the GM website.

Stellantis (Alfa Romeo, Chrysler, Dodge, Fiat, Jeep, Maserati, RAM)

The company formerly known as Daimler-Chrysler has also kept quiet on its 3G sunset situation. However, as car news sites Jalopnik and Automotive Fleet have pointed out, it already has gone public with its goal of making $22.5 billion from connected service subscriptions by the end of the decade. So theoretically, it's in their interest to fix this for customers. It'll just charge them for it.

Even cars as new as 2021 are impacted. Case in point: the Honda Pilot. Honda

Kia's UVO infotainment system runs on Verizon, which means drivers have a little more breathing room. Kia


The Korean brand is also keeping its plans to itself, but we've reached out for an update and it appears the UVO infotainment system runs on Verizon , so the carmaker and drivers have until the end of the year to figure out a fix.


Ford and Lincoln's shared SYNC system uses AT&T which indicates the cars listed in this NHTSA bulletin will be impacted Tuesday.

  • Continental, 2017
  • MKC, 2015-2017
  • MKX, 2016-2017
  • MKZ, 2015-2017
  • MKZ Hybrid, 2015-2017
Mazda CX-5s made between 2016 and 2019 will be affected. Mike Ditz


Mazda's plan for dealing with the 3G shutdown has been somewhat murky. Many news stories on this issue are pointing to a memo from the carmaker's recalls division about how to handle used cars or auction vehicles that may be affected; however, we couldn't find any information intended fo consumers. The models mentioned in that memo include:

  • CX-5, 2016-2019, 2020
  • CX-9, 2016-2019, 2020
  • CX-3, 2016-2019
  • Mazda 3, 2016-2018

Mazda's corporate offices were closed Monday; this section will be updated Tuesday once we hear back from their media relations team about what current customers should do.

The good news: Mazdas use your cellphone to call emergency services in the event of a crash, so if you are on 4G, LTE or 5G, you're covered.


Mercedes has been keeping its list of impacted vehicles to itself, though we've reached out for comment. However, because its telematics run on the Verizon network , your car has a stay of execution until Dec. 31.


Like its parent company, BMW, MINI hasn't publicly shared a list of affected cars.


Mitsubishi owners can breathe easy knowing that the carmaker skipped 3G entirely.


Nissan and Infiniti have relied on the AT&T 3G network, which means drivers will lose access to telematics data on Tuesday.

These Nissan vehicles will no longer be able to access NissanConnect or NissanConnect EV features:

  • Altima, 2016-2017
  • GT-R, 2017-2018

Subaru's Starlink telematics system – which handles automatic collision notification, emergency assistance, stolen vehicle recovery, remote door locking and unlocking – will cease operating in several models on Tuesday, according to its website.

Tesla Model S cars built before 2015 are impacted. Richard Vogel, AP


While all Teslas come with Wi-Fi and cellular connectivity, the electric vehicle manufacturer says only Model S cars built before June 2015 without a 4G-capable modem will lose these features unless connected to Wi-Fi:

  • Having your doors unlocked remotely
  • Mobile app functions. like Summon, cabin pre-conditioning, vehicle location, remote unlock, etc.
  • Navigation, live traffic updates, Supercharger available and outage information and onboard map updates
  • Music streaming
  • Over-the-air updates

Impacted users will need to upgrade to an LTE-capable modem, which they can schedule through the Tesla mobile app, for $200. Later Tesla vehicles – including Model X, Model 3 and Model Y – come standard with LTE modems, connected to the AT&T network, but owners may still get a notification on the car's screen or in the Tesla app that the software may require an update "to maintain connectivity after the carrier network changes take effect."


According to the German carmaker's 3G sunset FAQ , the VW Car-Net services will stop working in all eGolfs and other models made between 2014 and 2016. This means the cars will no longer have access to Safe and Secure functions like roadside assistance, emergency calls, crash notifications, remote access, fuel status, trip statistics as well as nanny functions such as curfew alerts, speed alerts and last-parked location.

While you'll know you're disconnected if you get in your car and the green light in the overhead console doesn't turn on, here's the list of impacted cars:

  • Passat, 2014-2019
  • Jetta, 2014-2019
  • EOS, 2014-2019
  • Tiguan, 2014-2019
  • Beetle, 2014-2019
  • Atlas, 2018-2019
  • Arteon, 2018-2019
  • Golf, Golf R, Golf Sportwagen and eGolf, 2014-2019
  • GTI,  2014-2019
  • CC, 2014-2018


Since Volvo partners with AT&T, the Feb. 22 sunset date means drivers will lose access to their infotainment apps , SOS and On Call in-car services, along with the Volvo Cars app's remote services.

The Swedish label notes the necessary upgrade is not covered until the factory warranty and that due to supply-chain issues, they don't have enough upgrade parts for most models. XC90 SUVs built-in 2016 X won't get a solution until later this year.

Volvo did not publish a list of cars on its website; however, Consumer Reports says these vehicles are impacted:

  • S60, 2015.5 to 2018
  • V60, 2015.5 to 2018
  • V60 Cross Country, 2015.5 to 2018
  • XC60, 2015.5 to 2017
