Description
Hyundai is initiating a new recall campaign 203, a safety recall to address a condition involving engine failures resulting in a vehicle stall and/or fire in certain model year 2019-2020 Hyundai Elantra, 2019-2021 Hyundai Kona, and 2019-2021 Hyundai Veloster vehicles equipped with 2.0-liter “Nu” MPI engines and produced for sale in the U.S. and Canada. Hyundai is initiating this action to ensure the safety and compliance of its vehicles.
The engines in the subject vehicles may have been assembled using piston oil rings that were produced with inconsistent heat treating by the piston oil ring supplier resulting in excessive oil ring hardness. Excessive hardness can cause chipping of the piston oil ring’s outer periphery, which could lead to scuffing of the engine’s cylinder bore. A damaged cylinder bore could create accelerated oil consumption, which may then cause abnormal knocking noise from the engine and/or illumination of the oil pressure warning light. Continual operation of the vehicle in this condition could result in a seized connecting rod bearing, which could cause damage to the engine block and eventually stall the vehicle. In limited instances, a seized connecting rod could puncture the engine block and cause engine oil to leak, which, in the presence of hot surfaces, could increase the risk of a fire.
