“The electronic warning sign for unlocked seat belt comes on while the car is moving, including at high speed on freeways. Unlocking and re-locking the seat-belt does not fix the problem. This problem has been occurring on and off for a couple of years and I am concerned about the potential the airbag may not deploy appropriately in case an accident/collision.”
