U.S. safety regulators are investigating the potential for air bags to fail because of software issues in older Chevrolet Impala sedans made by General Motors Co (GM.N), after receiving a consumer complaint about an alleged incident in Texas.
The National Highway Traffic Safety Administration said Friday that it has opened a probe into about 320,000 Impalas from model year 2008, but would also look at 2007 and 2009 models.
