Plain-English summary
Hyundai Motor America is recalling approximately 158,493 vehicles from the 2019–2021 model years: Kona, Elantra, and Veloster models equipped with 2.0L Nu MPI engines. The piston oil rings in these engines may not have been properly heat-treated during manufacturing.
Improperly heat-treated piston rings can result in engine damage. This damage may cause the engine to stall while driving, which increases the risk of a crash. Additionally, damaged engines may leak oil onto hot exhaust components, which increases the risk of fire.
Owners of affected vehicles should contact Hyundai customer service at 1-855-371-9460. Dealers will inspect the engine and replace it if necessary at no cost. Hyundai will deploy Piston Ring Noise Sensing System (PNSS) software as part of the remedy. Owner notification letters were mailed on August 24, 2021.
