Just an opinion, but we activated 5mph locking on our X and hate it. Because it doesn't unlock when you stop, the only doors that are open are the ones you get out of, and that takes two door handle pulls.

I try an remember to hit the unlock every time I stop now because I can't open the liftgate, gas cap or passenger doors without doing so first. I like to lay my jacket on the back seat and constantly go to get it and realize the rear door is locked. You can't open any door for your passenger (helpful if you have ladies or children in back) if you forgot to hit the unlock. Also, if you hit the rear hatch button, it is a race to the back to beat it from relocking itself before you get there. This makes the hatch button usless, might as well just hit the unlock button and use the opener on the hatch itself.

I will be removing this option at my 1st dealer visit.
