Hyundai Class Action Lawsuit Over Excessive Engine Oil Consumption

A Hyundai oil consumption lawsuit blames the automaker for not making buyers aware of excessive engine oil consumption issues in more than 20 of its models.

Owners say Hyundai should have recalled the vehicles because the engines allegedly use excessive amounts of oil, stall, and eventually fail because vehicles are equipped with defective Nu, Gamma, Theta, Lambda, and Kappa engines.

On Apr. 12, 8 owners filed a class action lawsuit against Hyundai in a California federal court for violating federal warranty laws.

Hyundai and Kia Models With Excessive Oil Consumption Issues

According to the Hyundai and Kia class action lawsuit, the below Hyundai and Kia models have excessive oil consumption problems.

  • 2012-2020 Hyundai Elantra
  • 2009-2018 Hyundai Genesis Coupe
  • 2019-2021 Hyundai Kona
  • 2020-2021 Hyundai Palisade
  • 2010-2012 and 2015-2021 Hyundai Santa Fe
  • 2009-2010 and 2015-2021 Hyundai Sonata
  • 2011–2021 Hyundai Sonata Hybrid
  • 2010-2013 and 2015-2021 Hyundai Tucson
  • 2011-2021 Hyundai Veloster
  • 2020-2021 Hyundai Venue
  • 2010-2021 Kia Forte
  • 2017-2020 Kia Niro
  • 2011-2020 Kia Optima and Optima Hybrid
  • 2012-2021 Kia Rio
  • 2011-2020 Kia Sorento
  • 2012-2021 Kia Soul
  • 2011-2020 Kia Sportage
  • 2018-2021 Kia Stinger
  • 2022 Kia K5

The Hyundai and Kia oil consumption lawsuit alleges owners constantly use excessive amounts of oil, costing their owners huge sums of money. The plaintiffs also say adding too much oil isn’t the solution because by adding oil above the maximum fill line the crankshaft will be partially or fully submerged and too much oil will strain and damage the gaskets and seals protecting the engine which leads to oil leaks.

According to the suit, other than oil consumption, defective engines migrate oils to places it shouldn’t be, and it causes damage to the combustion and exhaust systems and keeps them from operating properly.

The lawsuit alleges owners must constantly check the oil levels more than normal, and oil must allegedly be added to the engines more frequently than even the owner’s manuals recommend.

This allegedly causes “abnormal wear of engine parts, oversaturation of carbon and deposits of oil sludge, ultimately requiring a costly engine rebuild or replacement.”

Hyundai Should Honor Warranty Claims Outside of Terms

According to the Hyundai class action suit, Hyundai should honor warranty claims even when the warranties have expired.

The plaintiffs allege that Hyundai should have recalled the vehicles but hasn’t. According to the lawsuit, Hyundai, and Kia can’t adequately repair the oil consumption problems but the automakers deny coverage if owners cannot provide maintenance records.

The Hyundai oil consumption lawsuit was filed by these plaintiffs:

  • Davy Cho / California / 2022 Hyundai Santa Fe
  • Bryan Rothmaler / Illinois / 2017 Hyundai Tucson Sport
  • Beth Makie / Massachusetts / 2016 Kia Sorento
  • Anna Chmura / Wisconsin / 2018 Hyundai Santa Fe Sport
  • Anthony Banderas / Nevada / 2020 Hyundai Kona
  • Michelle Smith / Florida / 2016 Hyundai Sonata
  • Catherine Little / Texas / 2017 Hyundai Sonata
  • Luticia and Thomas Thompson / Kentucky / 2016 Kia Sorento

The automakers allegedly don’t warn customers about excessive oil consumption issues even when the symptoms match, then owners must put their vehicles through oil consumption tests. And those tests require driving thousands of miles to determine if excessive amounts of oil is consumed and costing money out of the owner’s pocket.

And the suit also says owners must suffer through long wait times for replacement parts,  “and in most cases do not receive required engine replacements.”

Meanwhile, Hyundai has expanded its recall for exploding seat belt part issue which has caused multiple injuries including 6,240 of its 2021-2022 Elantra and 2020 Accent vehicles.
