CarPlay mic doesn't work for calls or texts

Have been using CarPlay with my iPhone for years via wired connection with no problems. I have a mic installed in my car. About 2 months ago, whenever I go to make a phone call, when the call actually starts the mic suddenly stops working and the other person can't hear me. When I go to send a text, when siri asks me "What do you want to say?", when I answer the mic doesn't work and the phone can't hear me. The mic works FINE when I tell siri to make a call or I tell siri to send a text (or when I tell siri to play music or whatever), but when the call actually starts the mic suddenly doesn't work and when I'm asked WHAT text I want to send the mic suddenly doesn't work. I would think this has to be a CarPlay issue. Anyone else having this?

Note: I am currently using an iPhone 13 Pro Max, all software is updated.
