Hyundai Motor Co. said Friday it's recalling about 120,000 2004- and 2005-model Elantra sedans because of a software problem with its air-bag system.
The automaker said it acted voluntarily in response to a crash test conducted by the Insurance Institute for Highway Safety.
Spokesman Mike Anson said the air bag failed to deploy in a test conducted by the institute in May, but worked properly in 25 subsequent tests done independently and by Hyundai. There have been no reports of accidents or injuries related to the failed test, Anson said.
Hyundai said it will install a software change on all affected vehicles. It said the change will help the vehicles respond to the conditions of the 40 mile-per-hour, 40 percent offset frontal barrier test that the insurance group conducted.
"Owners of all 2004 and 2005 Elantras will be contacted directly with instructions on how and where to obtain the free software change," the Korean automaker's U.S. subsidiary said in a news release from its headquarters in Fountain Valley, Calif.
