My experience.
Rear passenger door would not open inside or outside. (child safety lock was on too)
Brought to dealer.
They seem to dismiss the whole door handle in cold weather bulletins.
Looked at my car for an hour.
They said I had a broken actuator. Personally, I didn't see any sign that my door was even open to diagnosed the problem.
Dealer wanted to charge me nearly $600 to fix the issue.
I left and said I think about it.
The dealer didn't even charge a diagnostic fee which I was expecting. Why they throwing that egg away? Strange.
Went home, a few days later I opened the door and saw a broken cable then proceeded to fix it myself. The cable holding the round metal ball broke free. Not a true fix but I McGuyvered it really.
Working ever since.
Saved $600.
End of story.
Good Luck!
