I was sitting in the passenger seat unbuckling the seatbelt. A loud noise went off behind me right almost like a gun shot. The seat shot from my hand and tore the leather in the car near the wind. The seatbelt also started smoking and left a smoke residue on the car. The seatbelt in locked in position and cannot be used any more. My right thumb was hit and at this time is in excruciating pain. I cannot make a fist. Iâm headed to the doctor for more specifics.
