I having the same issue. I have a fW 16. Here is the thing. Aug 2024 I was able to backup my iPhone 15 until I updated the IOS 17.1.2 or greater. I noticed my phone began to go in and out of car play as well. I have tried multiple types of UCB-C cables and still had the same issue.
This is just something to consider. The USB-A hub does work along with other types of phones.
