        How this compares

        2020 Hyundai Sonata178
        Median 2020 model here (32 vehicles)353
        Median 2020 sedan here (6)246

        178 complaints is 2.0 times fewer than the median 2020 model on this site and 1.4 times fewer than the median 2020 sedan. Among the 11 Sonata model years here it ranks 6th for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.

        40 complaints came in 2024, 3.3 times the year before. Owners file in waves when a problem gets press or an investigation, so a spike measures attention as much as failures.

        Loss of motive power. Closed dec 12, 2023.

        NHTSA summary
        The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan as
