DETROIT — Hyundai is recalling nearly a half-million midsize cars in the U.S. to replace key engine parts because a manufacturing problem could cause them to fail.
The recall covers 470,000 Sonata sedans from the 2011 and 2012 model years equipped with 2-liter or 2.4-liter gasoline engines.
The company says metal debris may not have been removed from the crankshaft. That can restrict oil flow to the connecting rod bearings, causing them to fail. If that happens, the engines could stall and cause a crash.
Dealers will inspect the cars and replace engine assemblies if necessary for free. The company also will increase the engine warranty for 10 years or 120,000 miles.
Owners will be notified Nov. 2 and the recall will start when parts are available.
