One problem related to door latch has been reported for the 1997 Mazda 626. The most recently reported issues are listed below.
The car door of my Mazda 626 1997, has a safety defect. The front passenger door does not stay closed after it has rained and then the next morning when it remains below freezing temperature. The door locked and was closed, but flew open when I was driving to work. I stopped my vehicle opened and closed the door and relocked it, it remained closed until I went around a corner and the door opened on its own. This is a serious safety concern.
