anyone having pixel 6 issues

I have RMA'd my P6. 3 times whilst being idle it locked up - black screen, power button did nothing, plugging in charger gave no response (battery was between 80 and 90 percent)...pressing power and vol. down for about a minute with it plugged in forced it to the menu allowing a restart.

I factory reset and during the setup whilst updating the standard Google apps the same thing occurred.

so I have RMA'd. it arrived with Google yesterday early morning but there I'd no repair update on my account, it doesn't even acknowledge their receipt yet, which is a worry.
