My 2021 S I bought used has been rather as expected in terms of issues... which is to say I have a similar experience to you, somewhat due to the prior owner leaving a litany of subtle issues for me to find and get serviced and also due to the S-ness. It's low volume, so I get it, but I think most of the cheapness is not safety related (except that all PS4S on 21" configurations should be fired into the sun they are such utter crap in terms of longevity and handling feel).
