The US is repairing about 6 million pickup trucks and SUVs to General Motors and is equipped with a potentially dangerous Takata air bag inflower.
The decision, announced Monday by the National Highway Traffic Safety Administration, would cost the automaker $ 1.2 billion, about a third of its net income this year.
GM petitioned the agency four times in 2016 to avoid the recall, saying the air bag inflator canisters had been safe on the road and in testing. But the owners responded by accusing the company of adding benefits to security.
Takata used volatile ammonium nitrate to make a small explosion to fill air bags in an accident. But when exposed to heat and humidity the chemical can deteriorate and explode with too much force, blowing and splattering a metal canister.
Twenty-seven people have died worldwide, including 18 in the US
It took the agency more than four years to reach its decision.
NHTSA said in a prepared statement that it analyzed all the data available on the air bags, including engineering and statistical analysis, aging tests and field data.
“Based on this information and the information provided to the public docket of the petition, NHTSA concluded that the GM inverter in question carries the same type of explosion risk after prolonged exposure to high heat and humidity because others Recalled Takata Inflotator “Agency stated.
The statement said the company has 30 days to notify NHTSA to vehicle owners and start back.
GM said that although it believed the recall had not been warranted on the basis of factual and scientific records, it would follow the NHTSA decision.
“The safety and trust of the people who drive our vehicles is at the forefront of everything we do at General Motors,” the company said in a prepared statement.
The decision means that all Tamata ammonium nitrate infloters in the US will be recalled, NHTSA said. Earlier this year the agency decided not to withdraw the inflower with a moisture-absorbing chemical called a desiccant. But NHTSA said that if any problem arises it will monitor those information and take action.
In the 2019 petition for NHTSA, GM stated that the inflowers were designed to its specifications and are safe, with around 67,000 air bags deployed to the field even when there is no explosion.
But Takata declared the GM Front Passenger Inflotator defective under a 2015 agreement with the government.
The explosion in Takata’s inflowers led to the largest series of auto recall in American history, recalling at least 63 million inflowers.
In its petition, GM stated that Northrop Grumman tested 4,270 inflators by artificially added humidity and temperature cycling, and there were no explosions or unusual deployments. It added that GM has established that “at any point due to poor-to-worst-case humidity exposure and temperature cycling … not even an inflator breakdown during improperly conservative vehicle service life estimates.” Will happen.”
The explosion in Takata’s inflowers led to the largest series of auto recall in American history, recalling at least 63 million inflowers. The US government says that as of September, no more than 11.1 million were fixed. Around 100 million inflators have been recalled worldwide.
Most of the deaths have occurred in the US, but they have also occurred in Australia and Malaysia.
Drivers can check to see if their vehicles have been recalled.
The recall bankrupted Takata of Japan and made criminal charges against the company. Eventually it was purchased by a Chinese-owned auto parts supplier.
