This Sync Connect system from Ford sounds nice; announced in late 2015. (I just had a friend lock himself out of his truck in a snowstorm - reminded me of the hazards and that there should be a tech solution, so I googled.)
The Ford system also reports vehicle status: fuel level, tire pressures.
Says it arrives on Escape first.
Has anyone tried it?
Did it ever trickle down to C-max?
