3G networks shutting down in 2022 could affect your car’s GPS

The 3G wireless network was once among the world’s hottest innovations. Today, it feels old-fashioned with fifth-generation (5G), and even sixth-generation (6G), networks soon dominating the tech world.

In fact, 3G will soon be extinct — and that could mean bad news for your car.

Every major mobile carrier plans to shut down its 3G network this year, largely to free up mobile bandwidth for upcoming 5G network rollouts. If your smartphones and tablets were purchased within the past decade, they should have 4G capability, meaning they’ll likely be unaffected.

However, your car might be a different story.

Other carmakers, like Bentley and Stellantis, have acknowledged that some of their cars will be affected, but have declined to specify which models.

Here’s a current list of publicly known affected models:

Acura: 

  • MDX models produced between 2014 and 2017
  • ILX (2016-2017)
  • RDX (2016-2017)
  • RDX (2019-2021)
  • RLX (2014-2016)
  • TLX (2015-2017)
  • NSX (2017)

Acura’s website identifies seven different vehicle models with AcuraLink features running on 3G, including real-time traffic and maintenance reminders, emergency calls and enhanced roadside assistance services, as well as some personal concierge services. The Japanese luxury brand, which is owned by Honda, says drivers should contact…
