Aren't there (at least) two distinct failure behaviors? I had a rear door handle fail, in such a way that it would no longer present. But just this weekend for the first time, I have had problems with my driver's door, with a different behavior: the handle extends, but further than usual, and it gets stuck in the extended position. Pulling on the handle does nothing, and the door must be opened from the inside. I assume these two different behaviors indicate two different types of internal failures.
