The U.S. is making General Motors recall and repair nearly 6 million big pickup trucks and SUVs equipped with potentially dangerous Takata air bag inflators.
The decision announced Monday by the National Highway Traffic Safety Administration will cost the automaker an estimated $1.2 billion, about one third of its net income this year.
GM had petitioned the agency four times starting in 2016 to avoid a recall, contending the air bag inflator canisters have been safe on the road and in testing. But owners say the company has placed a priority on profits, not safety.
Exploding Takata inflators caused the largest series of auto recalls in U.S. history, with at least 63 million inflators recalled. The U.S. government says that as of September, more than 11.1 million had not been fixed. About 100 million inflators have been recalled worldwide.
The recall covers GM full-size pickup trucks and SUVs from the 2007 through 2014 model years, including the Chevrolet Silverado 1500, 2500 and 3500 pickups. The Silverado is GM’s top-selling vehicle and the second-best selling vehicle in the U.S. Also covered are the Chevrolet Suburban, Tahoe and Avalanche, the Cadillac Escalade, GMC Sierra 1500, 2500 and 3500, and the GMC Yukon.
Takata used volatile ammonium nitrate to create a small explosion to fill air bags in a crash. But the chemical can deteriorate when exposed to heat and humidity and explode with too much force, blowing apart a metal canister and spewing shrapnel.
Twenty-seven people have been killed worldwide by the exploding inflators including 18 in the U.S.
It took the agency more than four years to arrive at its decision.
NHTSA said in a prepared statement that it analyzed all available data on the air bags, including engineering and statistical analyses, aging tests and field data.
“Based on this information and information provided to the petition’s public docket, NHTSA concluded that the GM inflators in question are at risk of the same type of explosion after long-term exposure to high heat and humidity as other recalled Takata inflators,” the agency said.
The company has 30 days to give NHTSA a proposed schedule for notifying vehicle owners and starting the recall, the statement said.
GM said that although it believes a recall isn’t warranted based on the factual and scientific records, it will abide by NHTSA’s decision.
The safety and trust of those who drive our vehicles is at the forefront of everything we do at General Motors,” the company said in a prepared statement.
