What Causes the Squeaking Sound from the Seat Belt Buckle?
1 Answers
The squeaking sound from the car seat belt buckle is usually caused by friction or contact with the passenger seat. It could also be due to the belt slipping on the pulley, which creates noise. Another possible reason is loose screws securing the seat belt. If it's a new car still under warranty, you can have the 4S dealership handle it during maintenance, or you can fix it yourself.

The passenger seat belt buckle might be too tightly damped, or the screws under the passenger seat may not be tightened or secured properly. The issue might not be the seat itself but the base underneath—tightening it should help. 2. Since the pin joints between the axle pin, bracket, and base have some clearance, driving on cobblestone roads can cause the axle pin to rattle. Additionally, there might be gaps between the flat washer at the axle pin and the limit base, leading to noise from the washer hitting the base during driving. If the internal limit lever of the adjuster is too loose or the adjuster's fixing bolts are loose, applying lubricant can resolve the issue.
