Hyundai is calling back nearly a half-million Sonata sedans to fix critical engine components.
Excess metal debris may not have been removed from the crank shaft on the affected vehicles, which are the 2011 and 2012 model year Sonatas equipped with 2.0-liter or 2.4-liter gasoline engines.
That extra metal can restrict oil flow to the connecting rod bearings, leading to failure of the bearings. In this case, the engine can stall, increasing the risk of a crash.
To fix the issue, Hyundai dealers will inspect and replace the necessary engine components. Also, the engine warranty on these cars will be stretched to 10 years or 120,000 miles.
