I really only noticed seat cover movement and had that worked on under warranty. Said they secured it and had the seat cover move on the way home from dealership. They ended up replacing seat bottom cover. It does not seem to move as badly as original so far, but it does move. Anybody come up with a fix for that? I have looked at how it is mounted and really not much holding it from sliding out of place. Whole seat started moving, as others have described on here, only after seat cover was replaced. Going to try hose clamp fix.
