Odds are the airbags in your car are the real deal, and will deploy when needed.  However, the National Highway Traffic Safety Administration warned today that car owners whose air bags have been replaced in the past three years may have dangerous counterfeit bags.   Tens of thousands of cars could be on the road with the faulty airbags.  NHTSA testing has shown most of the counterfeit airbags  do not inflate properly.  They also said they were usually only sent to auto repair shops, not new car dealer service centers.

If any of your vehicle's airbags were replaced within the past three years, and you have a concern, you can check a government website.  It's www.safecar.gov for information on how to contact a call center set up by automakers.
