iPhone 13 Pro Bluetooth Interference

I've seen this issue floating around on the Community forums about this and everyone seems to have some other reason for it. As my title says, I have an iPhone 13 Pro (iOS 16.3.1) and an Apple Watch Series 6 (WatchOS 9.3.1), and when my iPhone is connected to my car stereo, I'll get dropouts and interference while listening to podcasts on the way to/from work. Now, before you say it's my car stereo that could be the issue, this is happening in FOUR completely different cars. The ONLY thing that is common would be that the cars ranging from 2010 to 2017 use older Bluetooth technology in them. I've been in contact with Tech Support many times and talked with a few senior techs on the phone about this and all of them were stumped and escalated the issue up the tech support chain. I've been dealing with this since the iPhone 13 Pro came out on the market. I didn't have these issues with my previous iPhone 7 Plus. If I connect my iPhone directly to my car stereo via hardwire cable, it's fine but that's not the point here. It's 2023 and I shouldn't have to be connecting hardwired to listen to podcasts/music. Has anyone resolved their issues with Bluetooth and this iPhone?
