I have a different door lock problem that I've seen on the forum on my 08. My passenger side door lock will lock or unlock as its suppose to when I push the button. However, if I decide to push it again, it doesn't work for a while. I can see it try to lock/unlock, but it doesn't work till it "rests" for a while. All other doors function properly. I started noticing this a few months ago and it hasn't changed. I have a full warranty, so I'm not scared to take it in to the stealership, but I'm wondering if anyone else has had this type of problem before. No, I don't normally lock and unlock the doors all the time just to push buttons.
