“Seat belt and airbag indication lights and sound alarms remain on and notifying on the dashboard regardless of buckling. It will intermittently stop and start as the car is in motion. In the beginning, notification was present then resolved day-to-day. More recently, the alarm is present every drive. Driver was unsure whether or not the notifications were valid or not as the pattern of notification had little consistency. Dealership service later admitted that it was a faulty seat belt buckle and that part had failed internally, but refused to remedy it unless paid for. …”
