Hyundai is recalling nearly 500,000 Sonata sedans because a manufacturing problem could cause their engines to fail.
Hyundai has notified the National Highway Traffic Safety Administration that engines produced at its powertrain plant in Alabama may not have been machined properly. As a result, metal debris can block the flow of oil to the connecting rod bearings. That could cause the engines to stall and, in turn, lead to a crash.
The problem affects both 2.0-liter and 2.4-liter engines used in 470,000 midsize Sonata sedans sold during the 2011 and 2012 model-years. Those vehicles were all assembled by Hyundai in the United States.
