NHTSA recall did in August 22, 2000 unveiled defects in the seat belt assemblies of passenger vehicles, light duty trucks, mini vans and sport utility vehicle including 2001 Chevy Blazers. The buckle base of the car's seat belt assemblies were not properly installed and thus does not pass the load bearing requirement of federal motor vehicle safety standard.

In case of car crash events, passengers may not be properly supported to ensure safety. Remedy for this is inspection of the vehicle's safety belt buckle and if needed, replacement of the defective part.

The lighting system of this year's model also needs replacement of the hazard switch carrier as advised by the NHTSA in a recall did in December 13, 2001. Failure in the function of the hazard switch carrier may result to car accidents.
