I believe there is internal resistance to the Bolt. There have been reports of dealerships being reluctant to sell them. I remember reading an article mentioning it was hard for potential buyers to actually find a Bolt to test drive at a dealership even though GM had plenty of inventory.
I believe there are also supply problems in hot markets. The Bolt is currently sold out with waiting list in Canada, I believe it takes months to get one there.
