The short answer

NHTSA received Hyundai Motor America’s report on Apr 28, 2021. Copied from NHTSA on Oct 26, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

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.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt. Owners’ complaints are counted on each vehicle’s page.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • How many have been returned or fixed isn’t in the notice.
