iPhone stops working when connected to CarPlay 2022 Hyundai Tucson XRT

My internet doesn’t work when I connect wirelessly to Apple CarPlay. My car doesn’t have wired CarPlay options—this is something I don’t believe most some know. I was not told this when I bought the car, but a dealership told me this later.

My phone doesn’t have internet access when I am on my cars WiFi, and this happened when my bluelink subscription ended after purchasing it brand new in 2022 (the free 3 year subscription ended.) I have to either buy a new subscription, or have a useless iPhone that can’t use maps, Spotify, anything internet related. Please help!
