CarPlay won't use cellular data

Hello, two months ago, I got a 2024 Volkswagen ID.4. At first, there was a free trial of a hotspot through Verizon. It was fine, but I'd rather use my phone's cellular data.

Not long after that, I installed the iOS 18.1 beta. That's when I noticed that my phone was offline when connected to CarPlay. I have my maps downloaded, and much of my music and podcasts are configured to download locally to my phone, so I'm not sure exactly when it began.

I've exhausted the settings I can think of on my phone and my car's infotainment settings. I've tried:

  • Resetting Network settings on my phone
  • Confirming that Wifi Assist is enabled
  • Re-pairing my phone with my car
  • Turning off my car's Wifi Hotspot setting turns turns off wireless CarPlay. When I try to re-connect to CarPlay, I get a notification that it must be on to connect wirelessly.
  • Turning cellular data off and on

None have helped yet. Any ideas?

Our engineering teams need to investigate this issue, as resolution may involve changes to Apple's software. I'd greatly appreciate it if you could open a bug report and post the FB number here once you do. Bug Reporting: How and Why? has tips on creating your bug report.
