The recall covers 470,000 Sonata sedans from the 2011 and 2012 model years equipped with 2-liter or 2.4-liter gasoline engines. At the time, the Sonata was Hyundai's top-selling vehicle in the U.S.
Hyundai says that during manufacturing at Hyundai's Alabama engine factory there could not be all metal debris removed from the crankshaft area. This may cause a limitation of oil flow to the connecting rod bearings, and since they are cooled by oil, they could fail. If that happens, the engines could stall and cause a crash.
For driver warning, the connecting rod bearing will make a knocking noise, and oil pressure will make the light to illuminate.
From the displayed documents it is known that dealers will inspect the cars and replace engine assemblies for free to owners, but the exact parts to be replaced were not specified in the documents. The company will also raise the engine warranty for 10 years or 120,000 miles. Owners will be notified Nov. 2, and they'll get a second notice when parts are available.
The Accent recall covers 2009 to 2011 models. Hyundai says the brake light switch can fail, and the lights won't come on when a driver steps on the brakes. Also, the cruise control may not be deactivated by stepping on the brake, and the gear shifter may get stuck in the "park" position.
Hyundai will replace the brake switch at no cost to owners starting Nov. 2
