Apple CarPlay phone call audio issues

Hi all,

I just got a brand new car, a 2021 Kia Forte, and the Apple CarPlay does not work correctly when I make phone calls. When my iPhone 11 is connected via CarPlay with a USB cord, people hear my voice as distorted/blurred/crackling which makes it hard or impossible for them to understand me, but I can hear them perfectly fine. If my phone is connected via the car’s bluetooth only, the call will work perfectly and my voice is just fine to others (but then I can’t use CarPlay for other things, like Google Maps, which I rely heavily on).

I have restarted my phone and car several times, and disconnected and reconnected my phone to the car. My phone software is currently up to date, at 14.5.1. I’ve tried several different USB cords (all official Apple ones), even bought a new one, and it hasn’t changed anything. Please, any advice on how to fix this, or how to get Apple to include a bug fix in their next update, would be greatly appreciated.
