GM has such a chip shortage that they have started manufacturing full size vehicles without the modules being able to activate the dynamic fuel management (GM's idea on how to make active fuel management even worse) just to shave a few chips off the build. They're also eliminating hd radio and steering column locks to save chips too. It's a crazy time right now for vehicle manufacturing. There hasn't been a new vehicle on our lot for a full day in a couple months (Buick/GMC/Chevrolet dealership). New vehicles are being sold before they are delivered or within a couple hours of being delivered by the transport trucks. We've got more used non-GM vehicles than we do anything else right now.
