Well i had the same problem but have a coupe. It only affected one door. This was all under warranty but they never did replace it or remove it. Just sprayed some pb blast in it and called it good. There is a lot of dust that gets up into that area. I would have to hit the unlock twice to get the mechanism to engage properly. After they sprayed it the problem went away mostly. But if they replaced the part there must be another problem.
