NHTSA recall 14V415000

What's wrong: The affected vehicles may experience an oil leak from the front cylinder bank valve cover gasket. If there is a sufficient amount of oil dropped onto the alternator, the alternator will be damaged causing the charging system to become inoperative.

Why it matters: If the alternator is damaged, the charging system warning lamp in the instrument cluster will illuminate, and the engine will lose power and the vehicle will eventually stop operating while being driven. An unexpected failure of motive power while driving increases the risk of a crash.

The fix: Hyundai will notify owners, and dealers will inspect/repair or replace the alternator and the front valve cover gasket, free of charge. Hyundai sent out an interim letter to owners on September 3, 2014.
