Got my 2021 Acadia Denali last week. Drives great and love the feel overall, but the Lumbar support in the driver's seat digs into my back and there's no way to put it all the way down. It's incredibly uncomfortable as no matter where I place it, it feels like metal rods just digging into my back in what is an otherwise cushy front seat. Any help with this issue? Shouldn't I be able to move the lumbar all the way down so I can't feel it?
