Here's an interesting conumdrum: Unlock car and drive to local gas bar. Stop car and walk back to put gas in. Plate covering gas tank cap won't open. Unlock doors. Still won't open.
Keep pushing the unlock buttons, still won't open.
Lock doors, unlock all doors, push rear door button, check cover --- repeat about four and five times.
Finally hear clunk from cover plate area. Now opens and I can fuel the car.
Diagnosis and fix?
