Hyundai is recalling more than 220,000 Santa Fe SUVs and Sonata sedans because of potential problems with their air bags. The recall affects almost 200,000 SUVs from the 2007-2009 model years, according to the National Highway Traffic Safety Administration. These vehicles’ front passenger airbags may not deploy in the event of a crash because of a possible problem with their occupant classification system, which gauges the size of a passenger and based on that whether an air bag should be deployed.
