Elevated severity
This campaign addresses a defect NHTSA classifies as carrying elevated crash or injury risk.
What the defect is
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.
Why it matters
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.
The remedy
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.
What this page does not include
NHTSA's public recall feed does not supply an affected-population count, the manufacturer's own campaign number, owner-notification dates or a defect chronology for this campaign. Rather than estimate them, we omit them. Confirm whether a specific vehicle is affected — and whether the repair has already been done — using its VIN.
