Tesla Model 3 GPS Location Way Off – Anyone Found a Fix

I have a Tesla Model 3 and recently the GPS location has become completely inaccurate.
The car thinks it’s several streets away from my actual location, sometimes even a few kilometers off. This affects navigation, live traffic routing, and the location shown in the Tesla app.
Things I’ve already tried:
Rebooting the screen (both scroll wheels)
Powering the car off and back on
Checking that Premium Connectivity is active
Driving around for a while to see if it recalibrates
The issue still persists.
Has anyone experienced this before? If so:
What was the root cause?
Did it resolve itself or require a service appointment?
Was it a GPS antenna issue, software bug, MCU problem, or something else?
For reference, the car has a clear view of the sky and there are no aftermarket modifications that should interfere with GPS reception.
Any suggestions would be appreciated.
