Aside from the loss of the older (non-GX) Encore, the Buick lineup stands mostly pat for 2023. Envision models get a little shuffle of feature availablility.
All Buicks see constraints from supply-chain issues, mostly in heated seats, start/stop and parking sensors. Envision's blind spot and rear cross traffic sensors will be missing from some early build models, but when parts become available the dealership will enable them.
