Considering a Used 2018 GT w/ AWD: known problems?

[Getstung]

Hi all. I’m considering purchasing a Used 2018 Kia Stinger GT, with the 3.3 liter-turbo and AWD. I did some research on the car on Edmunds and Kelly Blue Book. Owner concerns were as follows: the rear hatch rattles; the sunroof rattles; the paint has .. “pin pricks” in it, and/or is chipping; rear visibility is poor; the driver’s seat is narrow; the rear seats are small; the brake rotors don’t last; and the fuel economy is lower than EPA rating.

So .. thoughts on the concerns I read about? Do you second them? Are there other concerns not mentioned in the reviews, I should be worried about?

For those that bought the 2018: are you happy with the purchase? Are there any .. first-year / new model concerns?

Thanks in advance for sharing your input!
