DETROIT -- U.S. auto safety regulators have expanded an investigation into malfunctioning air bag controls to include 12.3 million vehicles because the bags may not inflate in a crash.
The problem could be responsible for as many as eight deaths.
Vehicles made by Toyota, Honda, Kia, Hyundai, Mitsubishi and Fiat Chrysler from the 2010 through 2019 model years are included in the investigation, which was revealed Tuesday in documents posted by the National Highway Traffic Safety Administration. It involves air bag control units made by ZF-TRW Automotive that were installed in the vehicles.
The control units can fail in a crash, possibly because of electrical signals that can disable an air bag control circuit housed in the passenger compartment, according to agency documents. The electrical signals can damage the control circuit, the documents say.
ZF, a German maker of auto parts that acquired TRW Automotive in 2015, said in a statement that it's committed to safety and is cooperating with the agency and automakers in the investigation.
The case is the latest in a long list of problems with auto-industry air bags, including faulty and potentially deadly Takata air bag inflators. At least 24 people have been killed worldwide and more than 200 injured by the inflators, which can explode with too much force and hurl shrapnel into the passenger cabin. The inflators touched off the largest series of automotive recalls in U.S. history, involving as many as 70 million inflators to be recalled by the end of next year. A total of about 100 million inflators are to be recalled worldwide.
On April 19, the agency upgraded the ZF-TRW investigation from a preliminary evaluation to an engineering analysis, which is a step closer to seeking recalls. So far, only Hyundai, Kia and Fiat Chrysler have issued recalls in the case. Four deaths that may have been caused by the problem were reported in Hyundai and Kia vehicles and three in Fiat Chrysler automobiles. The agency opened an investigation in March 2017 involving the TRW parts in Hyundais and Kias.
The decision to upgrade the case came after investigators found two recent serious crashes involving 2018 and 2019 Toyota Corollas in which the air bags did not inflate. One person was killed. Toyota said it's cooperating in the investigation, is conducting its own investigation and will take "any appropriate action."
Jason Levine, executive director of the Center for Auto Safety, a nonprofit consumer group, said the ZF-TRW case shows the auto industry thus far has learned little from the Takata recalls.
"A single supplier of an important safety component provided what appears to be a defective part across multiple manufacturers and 12 million cars," Levine said. "While the first fatality reports emerged three years ago, it has taken a higher body count for more significant action to be taken by NHTSA, and most impacted manufacturers remain silent. The industry needs to do better."
A message was left Tuesday seeking comment from the agency. In the ZF-TRW investigation documents, the agency said it didn't find any other cases of electrical interference in Hyundai, Kia or Fiat Chrysler vehicles that used the ZF-TRW system but were not recalled. The agency has not identified any other cases of electrical interference in other Toyotas, including Corollas, since the company started using the ZF-TRW parts in the 2011 model year. In addition, no electrical interference cases have been identified in Honda or Mitsubishi vehicles with the same parts, the agency said.
Kia vehicles covered included 2010 through 2013 Forte compact cars and 2011 through 2013 Optima midsize cars in the U.S. Also covered are Optima Hybrid and Sedona minivans from 2011 and 2012. Recalled Hyundai vehicles included 2011 through 2013 Sonata midsize cars and the 2011 and 2012 Sonata Hybrid.
In 2016, Fiat Chrysler recalled about 1.9 million vehicles worldwide, including the 2010 Chrysler Sebring, the 2011 through 2014 Chrysler 200, the 2010 through 2012 Dodge Caliber, the 2010 through 2014 Dodge Avenger, the 2010 through 2014 Jeep Patriot and Compass and the 2012 and 2013 Lancia Flavia.
