— Five years after it was opened, a federal safety investigation has been closed into recalls of more than 12 million vehicles equipped with ZF-TRW airbag control units.
The National Highway Traffic Safety Administration opened the investigation to determine if the airbag failures during severe crashes were caused by safety related defects.
These models are included in the ZF-TRW airbag investigation.

All the vehicles are equipped with ZF-TRW airbag control units for the electronic control units (ECUs) used to receive signals from crash sensors mounted in the vehicles. The system is what deploys the airbags and seat belt pretensioners in a crash.
NHTSA sent information request letters to several automakers, including FCA, Hyundai, Honda, Kia, Mitsubishi and Toyota.
NHTSA learned about a problem with electrical overstress which caused harmful signals on the crash sensor wiring.
Hyundai recalled 155,000 model year 2011 Sonata cars, Kia recalled about 507,000 vehicles, and Fiat Chrysler recalled about 1.9 million vehicles for the airbag problems.
NHTSA says it kept this investigation open five years to monitor field performance of the airbags and vehicles, but the government didn't find any reports about vehicles not included in existing airbag recalls.
Safety regulators have closed the five year airbag investigation based on the recalls.
