I did have a couple of times where I'd answer a call and get blasted by distorted audio from my USB drive. It happened twice on the same drive from the same caller, but I've not been able to duplicate it. Other times, it's worked fine.

I don't stream tunes from my phone, so I can't comment on that. However, if you've got other items in the car using Bluetooth, it might be causing problems. I've heard reports on another forum that users of a particular smart watch were having problems using Bluetooth to stream their tunes.

My phone is the only Bluetooth device connected.

Is the car the only Bluetooth device connected (in range) of the phone?

Do you have anything connected to the diagnostic port of the car? Perhaps a car insurance device, or something to roll down the windows when you unlock the car?

Otherwise, given that you're getting USB audio when you should be getting phone audio, I'm inclined to think it's a problem with the car. You could try a reset of the radio. (You'll have to re-pair with the phone.) before taking it in.

all they did was delete my phone from the list of Bluetooth devices

Odds are they ran the reset - the side effect is that it deleted all phones from the list.
