Hugh Pickens writes writes: "Joan Lowry reports that that National Highway Traffic Safety Administration has alerted the auto repair industry that tens of thousands of car owners may be driving vehicles with counterfeit air bags that fail to inflate properly or don't inflate at all and although no deaths or injuries have been tied to the counterfeit bags, but it's unclear whether police accident investigators would be able to identify a counterfeit bag from a genuine one. The counterfeit bags typically have been made to look like air bags made by automakers and usually include a manufacturer's logo but government investigators believe many of the bags come from China. Auto dealerships that operate their own body shops are usually required by their franchise agreements to buy their parts, including air bags, directly from automakers and therefore are unlikely to have installed counterfeit bags but only 37 percent of auto dealers have their own body shops so many consumers whose vehicles have been damaged are referred by their insurance companies to auto body shops that aren't affiliated with an automaker. Safety officials will warn millions of Americans that the air bags in over 100 vehicle models could be dangerous counterfeits, telling them to have their cars and trucks inspected as soon as possible. Dai Zhensong, a Chinese citizen, had the counterfeit air bags manufactured by purchasing genuine auto air bags that were torn down and used to produce molds to manufacture the counterfeit bags. Trademark emblems were purchased through dealerships located in China and affixed to the counterfeit air bags which were then advertised on the Guangzhou Auto Parts website and sold for approximately $50 to $70 each, far below the value of an authentic air bag. The NHTSA has made a list of automobiles available that may be at risk for having counterfeit air bags."
