2017 GMC TERRAIN Seat Belts Problems

I was driving back home when I suddenly heard a loud pop and my car seat belt immediately tightened up. I saw smoke inside the car and the screen in my dashboard said "airbag service" There was no air bag physical deployed in the car so I believe it happened internally. Now my driver seatbelt will not retract and the front passenger seatbelt will not come out.

While in park and driving, the passenger seat belt locks and will not unlock. You must unfasten belt and refasten it. It does this multiple times during a trip. This has occurred since 2020.

The front passenger seat belt locks on passenger and will not release unless it is completely unbuckled. It keeps doing this for no reason. This was brought to dealer’s attention one to two years ago and they said I would have to pay cost of repair since warranty was off even though I purchased an extended warranty with this vehicle. The service department claims to have taken it apart and cleaned it but could not find problem. The problem is bad since passenger has to unbuckle belt multiple times during a trip.

WHILE CHECKING THE REAR VIEW MIRROR A 1998 CHEVY TRUCK CAME TP A SUDDEN STOP ON THE HIGHWAY, AND I COULD NOT MISS THE TRUCK THE DRIVER CLAIMED HE THOUGHT HE HAD MISSED HIS TURN, WHEN MY SUV COLLIDED WITH THE TRUCK. THE POWDER CAME OUT BUT THE AIRBAGS NEVER DID COME OUT,AND THE PASSENGER SEATBELT LOCKED.
