Domain Mapping Methodology: A single NHTSA recall campaign may involve more than one vehicle subsystem (such as electrical wiring affecting fuel delivery), so domain totals can exceed the total number of unique recall campaigns. Complaint and recall counts are grouped by broad vehicle system; component co-occurrence does not establish that an individual owner complaint is related to a specific recall campaign.
NHTSA Campaign #21V301000 Engine & Cooling
Affected Component: ENGINE
NHTSA Report Date: April 28, 2021
Safety Defect Summary: 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.
Safety Risk / Consequence: 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.
Authorized Remedy Instructions: 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.
Manufacturer & NHTSA 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.

Historical Reporting Note: Recall campaign counts are shown by model year and should not be interpreted as a vehicle reliability score. Campaigns may cover multiple model years, and newer model years naturally have had less calendar exposure time for new safety campaigns to be issued.
Safety recall campaigns on this page are associated with this make, model, and model year in NHTSA federal records. A campaign may apply only to certain vehicles based on production date, equipment, manufacturing details, or other campaign-specific criteria.
