Problem 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. Risk 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. Fix 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 were mailed August 24, 2021. Owners may contact Hyundai customer service at 1-855-371-9460.

Two numbers, one recall

Every safety recall carries two identifiers. 203 is the number Hyundai assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 21V301000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.

Both lookups check a VIN against the manufacturer’s own list and say whether the repair is still outstanding on that vehicle.

Which vehicles does 203 cover?

2019–2021 Hyundai Elantra and 2 other Hyundai models, 158,493 vehicles by the manufacturer’s count. A recall covers a build range, so the VIN decides whether one particular vehicle is in it.
