General Motors (GM) is recalling nearly 4.3 million vehicles worldwide due to a software defect that can, in rare instances, prevent the airbags and seat belts from functioning during a crash.

About the GM Vehicle Recall

According to the Wall Street Journal, a sensing diagnostic module in the recalled vehicles can improperly activate a test under certain circumstances. Under these rare circumstances, the vehicle’s safety devices, including the airbags and seat belt pretensioners, are prevented from activating if involved in a crash.

GM says dealers will repair or replace the faulty software on owners’ vehicles for free.

There have been three injuries and one death associated with the software defect.

Airbag Nondeployment Statistics

• The Fatality Analysis Reporting Systems reports that airbags failed to deploy in 18 percent of fatal frontal collisions reported between 1998 and 2006.
• The National Automotive Sampling System/Crashworthiness Data System (NASS/CDS) noted that non deployment occurred less in first generation airbags than in sled-certified airbags, 7 percent versus 11 percent respectively.
• About 2 percent of airbag non-deployment in fatal frontal collisions represented potential system failures.
