Improperly Heat-Treated Piston Oil Rings
A damaged engine may stall, increasing the risk of a crash. In addition, oil may leak onto hot exhaust components, increasing the risk of a fire.
Hyundai Motor America (Hyundai) is recalling certain 2019-2020 Elantra, 2019-2021 Kona and Veloster vehicles equipped with 2.0L Nu MPI engines. The piston oil rings may not have been properly heat-treated, which could result in engine damage.
Dealers will inspect and, if necessary, replace the engine, free of charge. In addition, Hyundai will deploy Piston Ring Noise Sensing System (PNSS) software. Owner notification letters are expected to be mailed June 25, 2021. Owners may contact Hyundai customer service at 1-855-371-946
