I'm not sure about the tires but I can look at the car fax as it has a good history at the dealership.I'm a reasonably new owner (6 mo) of a 2020; the heavy feel and the trolleying in pavement depressions definitely took some getting used to. It feels better with some drive time, and once I got new tires it really kind of became a non-issue, and I don't even notice it now. A lot of the newer used GXson lots are just about at the end of their OEM tire life, mine was at 29,000 miles and still on OEMs when I got it. Not sure if yours has newer tires or still OEMs at 54,000 miles?
