New MacBook Pro 13" 2020 with 4 Thunderbolt ports repeat shutdowns issue

Well I was with Apple Support around 3 hours trying to troubleshoot. Looks like for some reason during Recovery and normal operation my Macintosh Hard Drive failed to be 'mounted'. So I had to get into Recovery mode and mount the hard drive again.

Post that I do think that the random repeat shutdowns have stopped.

However, there's something new I noticed :

1. The % Batter power at my login screen is 3-4% lower than what it is when I fully log in and start to use my machine. Go figure!? Not very bothered about this one - as the tech support told me to format my machine - that was something that I was definitely not OK to listen to and OK to do!
2. The other issue is, I tried to shutdown my 'Bluetooth' and anyway I tried to do it, it causes my machine to shutdown - rather abruptly. Need to definitely get this checked with calling Apple support for sure. This one is a BIGGER issue!

Right so, day 3. Tried the following:

1. Erased the machine and gave it a new OS install. However, with 2 admin users and the Bluetooth still handling faulty with shut downs. The battery issue continues. The random shutdowns though have been fixed.
2. Then we tried creating a new volume and then installing the OS there on the new volume. Sort of looked like this might be the issue. However, worked for possibly 2 hours and then the Bluetooth shutdown issue reappeared and it is now not even triggered by the bluetooth. You startup the machine and it dies in 1 minute - for both the user profiles I created.
3. SAFE mode in all still works - Bluetooth connects, Battery shows the correct %. and it does not shutdown on Battery. Staying Safe is nice - but it kind of kills the 'normality' - very covid-ish!
4. :( need superior support help. Waiting to get this escalated now.
5. This is a new machine and I don't know if other users who have the same configurations have the similar issues!

So I would think this is Day 5 or 6, Finally I got an apple support person to screen share and showed him the actual issue. I also showed him the battery % being weird. He has taken a Capture Data from my machine and send it to the engineering folks. Hopefully we should have some word in a couple of days. SO lets see.

Latest updates on this issue.

Today (9-Aug-20) my Mac restarted on its own for sometime - and this time I did get an error when it restarted on its own. This is now looking like a kernel panic. I have managed to upload the logs into their analytics share that Apple support provided 2 days back. Just hope they look at the problem!

A new update today 15-Aug-20 (Happy Independence Day in India)

I finally submitted my Mac to the service centre to get a full 3 day debugging and diagnostics check. I should possibly have an update by Tuesday next week 18-Aug and will post the update at that time. They weren't able to figure out what the issue was and its sure that they need to do more tests on the machine. The Bluetooth freeze and shutdown (yeah! it now freezes too !!) was replica table at the service centre.

Its been almost a month since I got the MacBook from the store post replacement of the logic board. Looks like everything seems to be working hunky dory so far. So its going good.

This didn't help but thanks anyway! I don't know what else to do currently! Am stuck in SAFE mode with so much power and feeling powerless at the same time.
