Update: 

  • A judge dismissed a class action lawsuit filed by a group of vehicle owners against Hyundai Motor Co. in a California federal court. 
  • The class action lawsuit claimed a number of Hyundai and Kia model vehicles contained an engine defect that caused them to use an excessive amount of oil.
  • The vehicle owners argued the alleged defect, in addition to costing them money for the excess oil, caused the vehicles to stall and eventually fail. 
  • Court approval of the dismissal was not required as the class had not been certified nor proposed to be certified for purposes of a settlement, according to court documents.

Hyundai makes numerous models of Hyundai and Kia brand vehicles with defective engines that use excessive amounts of oil, costing their owners huge sums of money, a new class action lawsuit alleges.

On Apr. 12, eight owners of Hyundai and Kia brand vehicles filed a class action lawsuit against Hyundai Motor Co. in a California federal court, alleging violations of federal warranty laws.

The Hyundai excessive oil consumption lawsuit alleges that numerous models of the automaker’s vehicles are equipped with defective Nu, Gamma, Theta, Lambda and Kappa engines.

The defective engines allegedly use excessive amounts of oil, stall and eventually fail. The drivers say Hyundai should have issued a recall for the vehicles a long time ago but hasn’t.

As a result, thousands of Hyundai and Kia owners and lessees have allegedly been forced to constantly check the oil levels, and oil must be added to the engines more frequently than even the owner’s manuals recommend, Car Complaints reports.

The engine issue has flow-on effects like reduction in engine lubrication due to crankshaft submersion and gaskets and seals damage, which leads to oil leaks.

The plaintiffs also claim that oil in their vehicles migrates to places where it shouldn’t be, damaging the combustion and exhaust systems.

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

Automaker should honor warranty claims outside terms, Hyundai class action says

The plaintiffs allege that Hyundai should honor customers’ warranty claims even when the warranties have expired. 

According to the lawsuit, Hyundai can’t adequately repair the oil consumption problems and doesn’t offer any reimbursement for out-of-pocket costs caused by the issue.

The class action states customers must suffer through long wait times for replacement parts, “and in most cases do not receive required engine replacements.”

The cars with the allegedly faulty engines include the 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 and 2022 Kia K5.

Meanwhile, Hyundai has expanded its recall of vehicles with an exploding seat belt part issue that has caused multiple injuries to include 6,240 of its 2021-2022 Elantra and 2020 Accent vehicles. 

The plaintiffs are represented by Nye, Stirling, Hale & Miller LLP, Sauder Schelkopf LLC and Walsh, PLLC.

The Hyundai Oil Consumption Lawsuit is Cho, et al., v. Hyundai Motor Company, LTD., et al. in the U.S. District Court for the Central District of California.

    2018 hyundai santafe sport. I thought I was the only one adding so much oil, I took it to the dealer it was on limp mode, they supposedly checked the engine and charged me 150.00 just for reseting, but not diagnosing the problem. We should make a hash tag make it viral people need to be aware and realize hyundai are selling cars with FAULTY ENGINES.
    LETS MAKE IT VIRAL PLEASE we all need to fix our cars to get to our jobs.

  2. Jimmy Jones says:

    I have a 2016 Tucson limited. Less tan 100k miles. Burns a least a quart of oil per 1k miles. Had an oil consumption test performed at the dealer but was told 1 quart of oil per 1k miles was acceptable (even though this means if I didn’t add oil between changes it would be empty?). Would like to be added to suit.

  3. Michele Liden says:

    We own a 2017 Hyundai Tucson with about 80,000 miles and it is burning oil. We have to keep adding in between oil changes.

  4. Laurel says:

    I have a 2013 Hyundai Santa Fe sport. Religiously got oil changes. Had to carry cases of oil in the back because it burned so much constantly. Got an oil consumption test and dealer said it burns 8qts of oil every 3,500 miles!!! Ridiculous! They said I need a new short block engine. In turn, my catalytic converter is now shot and my car is dead. Can’t replace any of it because I can’t afford to. The catalytic converter is proprietary so I can’t get it fixed with after market parts. Hyundai is literally the worst. The dealers are the worst! Useless! The company just gives you the run around so you just give up! Please add me to this class action. Thank you!

    I have a Hyundai, Tucson 2017, and I just finished an oil consumption test, and was just on the line. I am feeling a bit insecure as I am planning on a 1000 mile road trip. If I blow the engine because of this I will be furious.

    Yep my 2016 Tucson does this and I am having an awful time with it. Pretty sure they transmission is screwed already.

  10. Elizabeth Wojtalewicz says:

    I bought my 2016 Hyundai Sonata used in January of 2022. Two weeks later I got the low level light. We put enough oil in it to get me to get an oil change. Two weeks later the light went on again. We could not find where it was leaking. Since then we have put in about 10 quarts of oil. I took it to my mechanic 2 days ago about it. He gave it another oil change and replaced the plugs because of fouling in one. I really love this car but with the price of I can not keep it up much longer. Huyndai needs to rectify this issuse ASAP. Please add me to this lawsuit.
