iPhone 13 Pro and Local Interference Issues (PLEASE READ CAREFULLY)

I've done extensive testing and talked with Apple about this (who seems to deny any of this). Still, since buying our iPhone 13 Pro phones a couple of years ago, my wife and I have had many issues with Bluetooth interference while listening to whatever is in our vehicles and driving around town (in our case, the Memphis, TN area). We BOTH have seen this and BOTH use different configurations to listen in our vehicles. Now, before I go any further, let me say this, we are traveling/commuting in our vehicles so it is NOT related to a particular phone and we cannot reset any settings to make any difference (that's already been tried and nothing changes).

This issue is NOT software-related but seems to be a hardware issue with the iPhone 13 Pro (I can't say if it applies to any other iPhone series as we only have iPhone 13 Pros).

When in our vehicles, driving around town, we experience either a complete dropout of Bluetooth (either audio dropout and/or loss of phone conversation while talking to another on a phone call connected to our vehicle's infotainment systems or a pause in listening to audiobooks or podcasts. I seriously doubt it's a vehicle infotainment issue as I've seen this same issue appear in FIVE different vehicles. Now, the issue did change in my 2022 Chevorlet Blazer as when the signal drops out, it doesn't stop the audio but switches to a mono signal and podcasts/music sound like listening through an old telephone receiver rather than a premium vehicle stereo system.

I've talked to Apple at length about this and all I get from them is that it's been escalated to senior tech support and NOTHING has been resolved and this has been going on for TWO YEARS. Has anyone else seen this?
