The company disclosed its third petition to escape the recalls on Tuesday in a filing with securities regulators.
The financial stakes are high. If the National Highway Traffic Safety Administration lets GM out of the recalls, the company says it could save $1 billion and avoid recalling up to 6.8 million full-size pickup trucks and SUVs from the 2007 to 2011 model years.
Takata inflators can explode with too much force and hurl shrapnel into drivers and passengers. At least 22 people have been killed worldwide and more than 180 injured.
The problem forced the Japanese company into bankruptcy protection and touched off the largest series of automotive recalls in U.S. history. Takata has agreed to recall up to 69 million inflators in the U.S. and 100 million worldwide.
In the filing, GM says the front-passenger inflators were custom-made for its trucks by Takata with bigger vents and stronger steel end caps than other inflators. No truck inflators have blown apart on roads or in extensive laboratory testing, the company says.
GM disclosed that it hasn't set aside money for the recalls, and if required to do them, "we estimate a reasonably possible impact to GM of approximately $1.0 billion," the filing says. The company is in discussions with regulators outside the U.S. and continues to gather evidence and share its findings, according to the filing.
