iPhone 15 Pro Car Bluetooth Connectivity Issues

An update:

iPhone 15 Pro updated to 17.4.1

Drive home yesterday looked like it was addressed but that only lasted until the next morning.

Issue remains but here is the sequence of events when the issue starts:

Connection to car drops, car goes into search mode. Upon finding phone and connecting, the millisecond audio starts playing, connection drops and cycle repeats. This may happen 3-6 times before connection appears to stabilize. The connection will stay stable from somewhere between 10 seconds to around a minute before it starts all over again.

Second update:

It doesn't matter what is running, the more bluetooth connections made to the phone, the faster the issue arises and the worse it is. Only having the car and Apple Watch connected still has the same issue just takes longer for it to appear. It almost feels like a heat issue is affecting the Bluetooth in the phone. It doesn't matter if it gets hot or has the car AC on it, it will happen. This morning I had an app going that played a track constantly without pausing and it caused the issue to repeat so much the car turned off the radio completely since it could not establish a stable connection and determined that there was no bluetooth device available.

I have had another weird update. So here is the setup, in my car there are two devices that have Bluetooth connections, the stock stereo and the dash cam. One day I did not have my Apple Watch on and added the Pokemon Go Plus+ and there were no issues. The next day I connected the Apple Watch and not the PGP+ and there were issues. I do believe that this may be an issue with the watch taking up most of the bandwidth of the iPhone. What's weird is that my previous iPhone (14 Pro) did not have this issue with having 4 devices connected at a time. It could be possible that the iPhone 15 Pro's Bluetooth is having issues handling this many connections simultaneously.
