Toyota Motor Sales, U.S.A., said it will recall approximately 119,000 of its 2003-2004 Avalon sedans because the front airbags could inflate when they're not supposed to.
If that happens, it could startle a driver and make a crash -- with no airbag protection -- more likely.
Toyota said it knows of no crashes or injuries caused by the problem.
The automaker said that certain circuits within the airbag control module may be susceptible to damage if they are exposed to some types of other electrical components.
If that happens, the car company said, "Front airbag(s) and/or seat belt pre-tensioners could inadvertently deploy."
Safety belt pre-tensioners work in conjunction with airbags. The pre-tensioners initially tighten belts when a crash is imminent, to hold the car's occupants away from the explosive force of the airbags deploying. Then the tensioners loosen in controlled fashion to let the occupants "ride down" the deflating bags, diffusing the crash energy.
Toyota says dealers will fix the problem by adding what are called "electrical noise filters" to the airbag control modules.
Owners of the recalled cars will receive notice in the mail.
