Chrysler is recalling just under 30,000 Fiat 500L small cars in the U.S. and Canada to fix a problem with air bags that protect knees in a crash.
The company says in a statement Wednesday that the bags may not inflate in the proper position if the driver isn't wearing a seat belt.
Chrysler says it doesn't know of any injuries from the problem.
The recall covers cars from the 2014 and 2015 model years including 25,500 in the U.S. and another 4,000 in Canada.
Dealers will replace the driver's side knee air bags at no cost to owners.
Chrysler says it will notify owners when parts are available. In the meantime, they should wear seat belts so the bags work properly.
