Suddenly crazy GPS

Had a US spec S24+ for a year. No problems until this week when the GPS lost its mind. Driving down the freeway yesterday morning (the 57 in SoCal) the AA display just started flying around. When I got to work, I immediately power cycled the phone. Checked that all the location permissions were on, etc.

Heading home, it started again. While stopped at a light the display said I was at a location nearly a mile away from where I was. Putting the phone on the dash didn't help.

I got a phone call, and after the call was done suddenly the GPS was rock solid all the way home. Huh.

I thought maybe it had been resolved, but this morning the same thing happened. And today I was driving a different car. (I have 3, all with AA.)

I'm going to try Waze in stead of gmaps this afternoon, but I'm not feeling the love from this phone.

Would it be worth the ETF of $600 to bail out on this and get a new phone? I live and die by GPS...
