I bought a 2017 GT AWD mostly for my wife to drive, but I like driving it more than I thought.

Haven't had any issues.

My only complaint (if you could call it that) is the trans calibrations are definitely biased towards mileage and NVH/smooth quiet operation.
I'd prefer more performance oriented trans cals but I am probably not the average customer.

I was told 3.6L is pretty clean/issue free after 2015, which might help since you were looking at mostly later models.

I forget the year brakes were upgraded, but it was sometime before '15.
The very earliest models had a reputation as brake eaters, that's fixed now.
