The National Highway Traffic Safety Administration (NHTSA) has agreed to delay a recall of certain General Motors vehicles equipped with potentially defective Takata air bags. The decision will give the manufacturer time for additional testing to prove that their devices are safe. The vehicles under investigation are certain 2007 to 2011 trucks and SUVs, including the Chevrolet Silverado and GMC Sierra.

The case first began when Takata filed papers with the NHTSA declaring that 40 million inflators from 17 auto manufacturers were defective and should be recalled. The addition pushed the number of recalled inflators to about 70 million, making it one of the largest auto recalls in the United States. In the petition to delay the recall, GM said its trucks and SUVs have experienced 52,000 airbag inflations with no ruptures. The company also said Takata tested 1,475 GM inflators and all worked as designed. According to General Motors, bigger vents, stronger steel end caps and solar-absorbing glass that reduces cabin temperatures has resulted in their airbags deploying safely.

If the 2.5 million truck recall is canceled, GM will likely seek the same decision for 4.3 million more trucks with the same inflators that are due to be recalled starting next year.
