There was a recall on the 2016-2018 Cadillac CT6 where there was extra adhesive on some of the lower anchors which made it difficult or impossible to connect a car seat to these lower anchors. See here for more information and to get this recall repaired if you have a CT6.
There is a regular version and a plugin version. They have some variations in the back seat – specifically the center seat is different in the 2 versions with the regular having a higher seat back in the center.
