1. The door is automatically locked when driving. This is normal behavior. However, when I reach my destination, I was not able to open the door, from the inside handle or outside handle.
2. I tried pressing the "door lock" button to unlock the door first, then try the inside or outside handle, to no avail.
3. Occasionally, after about 10-15 tries, the door will open. It seems that I have more success opening it from the outside handle, but always, at least with 10-15 tries.
4. The electronics seem to function normally. Even when using the key remote to unlock the door, I can hear the normal "clicking" sound, but the door will not open.

The strange thing is that it will eventually open after 10-15 tries.
Any idea?
