US expands probe into air bag failures to 12.3M vehicles

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 very little from Takata.
“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.”

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 probe, which was revealed Tuesday in documents posted by the National Highway Traffic Safety Administration. It involves air bag control units made by ZF-TRW that were installed in the vehicles.
The control units can fail in a crash, possibly because of unwanted electrical signals produced by the crash itself that can disable an air bag control circuit housed in the passenger compartment, according to NHTSA documents. The electrical signals can damage the control circuit, the documents say.
