Rear doors won't unlock
 

So if I push the door handle button once to unlock the drivers door then reach in and push the power unlock button on the door only the passenger door opens, but not the rears. Then after trying that the rear doors won't even lock if you unlock them manually and then push the lock button, or the lock on the remote...However if I drive the car again, when I shut it off all the doors unlock and everything is fine, as long as I unlock all the doors by pressing the button on the door handle twice.
Seems extremely stupid, but is there a setting that makes the locks not work for the back doors?

Child safety locks maybe?

That should only prevent the handles from working from inside the car.

Ive never tried to unlock the passenger doors from the inside lock switch after using the black button.

If you push the black button once to unlock drivers door, and then again, does it unlock the other 3? Thats what I do on my car and it always works.

I would say child saftey locks also, Check the tab on the inside of the door jam( On the door not the body)

Disclaimer alert!!!! I have the coupe so that means only two doors, however I know that there's a selective lock/unlock feature. Check through the setup up on the car and see if there is something that pertains to this.

The outer door black button does work if i push twice, but if I forget and only push it once and then want to let the rest of the people in the car the only way to do it is manually. Child locks are off.

you should prob take it to the dealers, because when I do what you stated above, all the doors unlock if I hit the unlock button on the inside of the drivers door.

Great...Now the locks are all working just fine. This will be fun to explain to the dealer...Sometimes they work sometimes not. Ohh well.
