Summary

Certain 2019-2022MY Veloster N (JSN), 2022-2023MY Elantra N (CN7N), and 2022-2023MY Kona N (OSN) vehicles are equipped with high pressure fuel pump (HPFP) assemblies that have fuel control valves (FCV) that could allow excess fuel to enter the fuel pump due to gradual wear of the FCV plunger. An air/fuel mixture that runs too “rich” may result in a reduction or loss of motive power at low speeds. The vehicle will also have Diagnostic Trouble Code (DTC) P0088. Hyundai is extending warranty coverage for the HPFP under this condition to 15 years or 150,000 miles from the date of original retail delivery or date of first use (whichever occurs first) and is valid for original and subsequent owners.

Owners of these vehicles have filed 11 complaints in the fuel system category.
