I found it was necessary to turn off the Park Distance Control (PDC) button on the lower center console when attempting to back up while the bike rack was installed. This prevents emergency braking(and driver whiplash). I know this was noted on previous posts, but might be useful for new Atlas owners. I also deactivated the Easy Open feature for the trunk lid as while putting on the bike rack I inadvertently opened the trunk lid, scraping it against the rack. I have a 2019 Atlas SEL Premium.
