CarPlay microphone not working properly on iOS16 on iPhone 14 ProMax

I have two iPhone 14 Pro Maxes that I got last week that are running iOS 16. Since upgrading my phones, when I connect to either of my cars (both Subarus) via Apple cable to CarPlay and make a call, the caller can barely hear me. Prior to upgrade, I had an iPhone 11 Pro Max and an iPhone 12 Pro Max using CarPlay in these same vehicles using the same cables and people could hear me clear as ever. Actually, I was always very impressed at how clearly the microphone picked up and filtered out background noise.

So is this problem iOS 16? Or is it the iPhone 14 Pro Maxes? I’ve not tested to see if it’s using the phone’s microphone or not. I just know that I sound like I’m VERY far away from the mic and very quiet.

If I’m on a call and unplug from CarPlay or just tap my speakerphone button, they can hear me perfectly fine. So I don’t think it’s using my phone’s microphone… or if it is, it’s using it in regular phone mode, not speakerphone mode.

I make many calls from the car, so this is not good!

I also had Subaru update my head unit (factory) to the latest version just to ensure it wasn’t something with my car. But it’s happening with two phones, two cars, so I think we can say it’s definitely the phones/iOS.
