2025 Nissan Sentra Seat Belts Problems

Your rear seat belt warning system is malfunctioning — it triggers alarms even when passengers have fastened their belts, and won't stop alarming until all seat belt buckles are clicked, regardless of occupancy. This has persisted through three dealer repair attempts, leaving you uncertain whether the rear seat belts will actually protect passengers in a crash. The issue likely requires the seat belt sensor system or wiring harness to be diagnosed and repaired or replaced.

Your rear seatbelt system is triggering false alarms even when passengers are properly buckled in. The alarm sounds within two minutes after someone unbuckles and exits the vehicle, or when they re-enter and buckle up. Your car is missing rear seat weight sensors that would normally prevent these false warnings, so the dealership is replacing the rear seatbelts with ones that have proper sensors.
