Transcript for Air Bag Recall
And a warning tonight about the air bags in your car. The national highway traffic safety administration warning about counterfeit air bags installed by repair shops. They look like the real thing, but they're not. So, how do you know what's in your car? Abc's david kerley on that. Reporter: This airbag, supposed to save your life, exposeds. Fire shooting out of the steering wheel. It's a counterfeit. Here it is again. The fake literally shooting parts and flames right at the driver. Or this bag, another fake, that only partially inflates. Customs agents were spotting fakes and when these tests of the suspected chinese-made counter counterfeits came back, the alert went out. When people try to think about counterfeiting having largely to do with somebody selling a bootleg dvd, we're dealing in a completely different world now. Reporter: This summer in charlotte, boxes of the fakes were confiscated in a raid. Some are sold on the internet, others to repair shops. This is only an issue if your air bag has deployed and you have to have it replaced. The government says goes to an authorized dealer and make sure you get the real deal. Less than a quarter million vehicles repaired over the past three years may be affected. The advice tonight? If you are not sure you got a real replacement, have a dealership check your new airbag.
