Front Seat Belt Retractor problems of the 1999 Saturn SL2

Vehicle rear ended while at a complete stop. Drivers' side seat back let go, and seat belt released, causing driver to be thrown forward and backwards. This was a low impact collision,and no injury would have occurred if seat and belt had held up during collision.

Cosco model 02-452 wal, manufacturing date unknown. When the booster seat was installed using the vehicle seat belts, the seat belt did not retract. The belt was stuck. The cause was unknown. The shoulder belt would go into the belt positioner to buckle the child tight, but if the child moved, the seat belt shoulder moved and remained loose, which caused the shoulder belt to not retract.
