The government is warning car owners about the risk of counterfeit airbags.
Published reports show the National Highway Traffic Safety Administration said replacement airbags installed in the past three years may fail or not inflate properly.
The agency also recommends calling the manufacturer or local dealership to see if the vehicle model is among those for which counterfeit airbags have been made.
The NHTSA said tens of thousands of cars may be affected.
No deaths of injuries have been tied to the counterfeit bags, but it's unclear if accident investigators would be able to identify a counterfeit bag from a genuine one.
