Bluetooth on brand new Galaxy S10e keeps un-pairing from my Subaru car audio.

[Android Central Question]

Every time I get back into my car, I have to shut the Bluetooth on the phone off, then turn it back on, in order to have Bluetooth connectivity. Sometimes I must do this more than once for it to connect. The Subaru system has properly stored the S10e, and the problem does not appear to be on the Subaru's end, but on the phone's end.
