It's not just Buick that's having part supply issues. Check pretty well any other manufacturer... they all have this problem. If the slow delivery is a reason to not procure future Buicks, I'm not sure which manufacturer you'd buy from... they're all pretty well in the same boat.
Regarding the wind noise from the driver's door window, it's been a known problem with pretty well every 2021 Envision out there resulting in a big demand for the parts. It took around 6 months for one of the 2 seals to come in for my driver's door. Still waiting for the other one but since the noise was reduced with the first repair, I haven't followed up.
