I have mine adjusted as well, but if they're too far out they can create gaps/wind noise between the hatch and car, dig into the paint they contact, as well as make closing the hatch less casual (ie - need more force). There's definitely a sweet spot where this seems to help with the rattle, but I think the bump stop fix is still the greatest single point for elimination.
The fact this is still an issue on 2022 models is laughable. Kia just isn't looking to refine things over time, just get the cars out there and let us worry about those loose ends.
