The official notice
Defect
On certain vehicles, the engine crankshaft may not have been properly cleaned to remove metallic debris during manufacturing. If the debris is not completely removed from the crankshaft’s oil passages, it can be forced into the connecting rod oiling passages restricting oil flow to the bearings, increasing the potential of premature bearing wear. If the vehicle continues to be driven with a worn connecting rod bearing, the bearing could fail, which could cause an engine stall while the vehicle is in motion, resulting in loss of motive power which could increase the risk of a crash causing injury and/or property damage. A worn connecting rod bearing could also result in the illumination of the oil pressure lamp in the instrument cluster.
Safety Risk
No risk description available.
Remedy
Dealers will inspect, and if necessary, replace the engine assembly. Hyundai will also increase the warranty for the engine sub-assembly (short block) to 10 years/200,000 kilometers for both original and subsequent owners of 2011 and 2012 Sonatas.
