Help! Door stopped auto-unlocking!
Is this a function that can be turned on/off? The doors still unlock from the remote, door button, and still lock at speed, but after turning the car off the doors wont auto-unlock all of a sudden. It's driving me crazy!

Did you check under your Options?
I think there's a unlock at exit option.

I think I've figured it out. Since I've only had the car a couple months I'm just now getting comfortable with it. I realized that now I pull the key out as I'm turning the ignition off, which doesn't trigger the doors to unlock. If I push in just a little bit to turn it totally off, then remove the key, it unlocks.
Kinda odd.

Does it still unlock when you use the buttons on the doors? If not, you have a bad relay in your door control module. If you are handy with a soldering iron, its a gravy easy fix...well documented here on the forums.
BTW, my driver side had the same problem. Still would not unlock after the module was rebuilt if you used the buttons, turned out my multi-button panel on the door was damaged. Fixed that too but it goes to show you NEED to diagnose what it is....I would not just turn it off and guess.
My .25 man, good luck.
