## What is wrong

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 can happen

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.


## Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1\-888\-327\-4236 \(TTY 1\-800\-424\-9153\), or go to www.safercar.gov.
