My 2021 Craz with an adjustable seat really doesn't move up and down much at all. I might get a few inches of movement up and down and even then it does not move easily at all. I really have to push and pull it to get it to budge. It slides forward and back and swivels just fine but not up and down. Does anyone have the same issue? Just wondering wondering if i need to bring it in to the dealer.
