According to the Associated Press, Hyundai is recalling 470,000 Sonata sedan cars in the U.S. to replace key engine parts because a manufacturing problem could cause them to fail. The recall covers Sonatas from the 2011 and 2012 model years that are equipped with a 2.0-liter or a 2.4-liter gasoline engine. 

Hyundai says that metal debris may not have been removed from the crankshaft during assembly. The debris can restrict oil flow to the connecting rod bearings, which could cause the engine to overheat, stall, and possibly cause a crash.

The Associated Press also stated that dealers will inspect the vehicles and replace engine assemblies, if necessary, for free. The company also will also increase the engine warranty for 10 years or 120,000 miles. 

Owners will be notified by Nov. 2, and the recall will start once the appropriate parts become available.
