Reviving this thread from 2019

I'm having this exact issue with my wife's Raven Model X (so MCU2 from the factory).
Since 2021.4.18.2, I've noticed the GPS location is spot-on while driving, but when we return back home and park 2 levels down in the underground parking at our apartment building, and after our Model X goes to sleep, each time we wake it up via the app or when we open the door to drive off somewhere, its location is incorrect.
If I keep checking the app while parked underground in order to stop it from going to sleep, the location is kept accurate, but as soon as the Model X goes to sleep and I get the "Waking up" message on the app, or if we open the door, the vehicle's location is set elsewhere.
Nearly instantly after the Model X exits the building and gets a clear view of the sky and is able to lock onto GPS signal, the location corrects itself and keeps itself corrected until we park again and the vehicle goes to sleep again.
As you can see from the image below, Smart Summon doesn't work, because the red arrow is placed on the location the vehicle is ACTUALLY sitting on (it's last location reported before loosing GPS signal), but then, it goes to sleep and the Model X thinks it's somewhere else, so it asks me to "Move closer to the vehicle" while I'm standing right next to it:
I thought this might get fixed with a software update, as each update uses the other side of the partition on the MCU, so we waited for 2021.12.25.7 but that didn't help.
I drive a 2017 Model S with the MCU2 upgrade, which is parked right next to the Model X, but my car doesn't have this issue. It always reports it's correct location, even while underground and after it wakes up.
I have tried:
*Removing the DashCam/Sentry USB drive.
*Countless double scroll wheel reboots.
*Changing the wheel size configuration back and forth.
*Done 2 Factory Resets...
But the problem still persists
.
I just have a fireman's loop and 12v battery disconnect left to try out.
I'm pretty sure it has something to do with the way the vehicle stores it's last location on the cache memory, which gets cleared while sleeping or it's recalled incorrectly after the vehicle wakes up. As you can read, I'm clearly not an expert on this...
What am I missing?
Any suggestions before opening a service ticket with Tesla?
