does the 18 suburban have the feature with rke and auto memory seat recall on that when you open the door with the door handle the seat will move to that rke keyfob settings. cant seem to get it to work like it did on my 15. thanks.

 

On my '17 I have to actually unlock it with the fob for the seat/steering/mirrors to move to the settings associated with that fob. Just unlocking the doors manually does not do it.
