general problems of the 2001 Mercury Marquis

The contact owns a 2001 Mercury grand Marquis. While driving approximately 40 mph, the driver's seat belt independently became loose from around the contact. He refastened the seat belt and proceeded driving. The contact stated the failure has occurred twice without warrant. The contact made an appointment with the dealer for further inspection of the failure. The approximate failure mileage was 131,952 and the current mileage was 132,000.

The driver's seat belt unlatches frequently and without warning. My husband has always been the one to drive the car and has ignored the problem. However, I am driving the car on a daily basis now and I'm concerned for my safety. I see many complaints and recalls for this problem on the internet, but there is no recall on my VIN. Help!! why is this problem a safety hazard and recall on some cars and not others???? it is terribly unsafe on any car!.
