Just over a year into ownership, 9200 miles, and I started up the truck earlier this week and I got the notification on screen that wireless android auto would not connect. I finally used the onstar button to call in and am waiting on a callback. I have tried two different phones, one of which was not connected previously, and it also has the same problem. From what I've read, wireless AA connects with WIFI, not bluetooth, so there appears to be a WIFI issue between the truck and my phone. One onstar person suggested I purchase a 2GB data plan for $15/month but I told her it was a feature sold with the truck and has worked for a year now and should continue working. I don't need a subscription for wireless AA to work in the vehicle, its a feature sold with 2021+ GMC sierras. I've gone through the AA app on the phone and nothing has changed. I think the WIFI hotspot needs to be active perhaps to work and it isn't. Any other suggestions? Wired AA does work fine.
