New cars have Pretensioners in the seat belts. It is a charge that goes off in the event of a crash that recoils the belts so the belt snugs up against you. If the crash deployed them then they will need to be replaced. Some pretensioners are in the seat belt(in the part that turns as you pull on it) and others are in the actaul latch and snugs that down in the event of a crash. So now days fixing up crashed cars is a bit harder because you not only have to replace the bags but also the pretensioners and also the module too usually.
