Issue:
On certain vehicles equipped with a 2.0 L Nu GDI engine, the connecting rod bearings could wear prematurely. As a result, there could be an abnormal knocking noise from the engine and/or the oil pressure warning light may turn on. If you continue to drive the vehicle with worn connecting rod bearings, the engine could fail. An engine failure would cause a sudden loss of power with an inability to restart. In some cases, a damaged connecting rod could puncture the engine block and cause an oil leak.
Note: For the Sonata model, only the Sonata Hybrid is affected by this recall.
Additional Note: Engine compartment fires can happen for many different reasons. In some cases, there is too much damage to find the cause of a fire.
Safety Risk:
A sudden loss of engine power could increase the risk of a crash. Oil that leaks onto a hot component could cause a fire.
Corrective Actions:
Hyundai will notify owners by mail and instruct you to take your vehicle to a dealer for an engine inspection test, to determine if there is bearing damage. If damage is found, the engine will be replaced. Dealers will also update the software for the engine control module.
Note: Hyundai recommends that you should always follow the correct vehicle maintenance schedule, which is printed in the Owner's Manual.
