The Nissan Path

When driving my passenger seat belt locks in place and will not allow the passenger to move. Any ideas as to what this issue is?? Is there a sensor or something that needs to be replaced?. It can be dangerous because it can choke my passenger easily

I think seat belts have a 10 year warranty, you can check your manual. If it's locking up when it should not then you can probably get the dealer to replace it. They should lock up when pulled out quickly (i.e. sudden deceleration from hard braking or an accident), but otherwise it should move freely.
