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.

3,221 thoughts onHyundai class action over excessive oil consumption dismissed

  1. Hope Lawrence says:

    I have a 2017 kia forte that burns oil like crazy and just seized up and shut off on me while driving. I looked on the kia website and supposedly my kia is not one of the “certain” engines that have this issue. Which doesn’t sound right since my car is having this exact same issue. I think they need to look into all of their engines.

  2. Brian Roth says:

    Our 2nd hand 2017 Hyundai Santa Fe Sport with 66,000 miles has excessive oil consumption using about a quart a week. Engine was rendered useless due to the excessive oil consumption. The Hyundai dealership says the car needs a new engine. I reached out to the Chief Customer Officer at Hyundai Motor America as I thought Hyundai would accept some responsibility for the engine issue. Hyundai refused to make any concession and stuck to their warranty to deny any reimbursement for the engine replacement. By the number of complaints on this site, it seems Hyundai doesn’t want to make its customer happy in the short run which should lead to many of us saying I’ll never buy a Hyundai or Kia automobile again. Very poor customer relations.

    1. DeCarros says:

      I’m having the same issue. 2016 Hyuandai Sonata. About 110,00 miles. Kept burning oil in between oil changes. Bout 800-1000 miles, oil is dirty or needs topping off. Now I need a new motor.

  3. FRAN TURNEY says:

    I have a 2017 Santa Fe. Sport and I have taken my car in to have the oil checked on it. Because it’s using too much oil. They did a cleanup and said that everything was fine, but I still use a quart of oil every 1000 miles and they’re saying that’s normal. They extended my warranty to a 110000 miles. And of course, now it’s over that. I took my car 2 A. Mechanic and he said the oil consumption is unusually high but Hyundai won’t do anything about it period I really love my car but this is unacceptable and Hyundai should be taking care of this. Period I have never had a car that uses that much oil. I tried to get into the
    Lawsuit, but I never heard anything about it until now and I see it’s been dismissed
    So what do we do now

  8. Christine Valway says:

    I too am experiencing the same issue with my 2019 Hyundai Tucson. It has 63,000 miles on it. It is burning through oil very quickly! There needs to be a recall on this – this is unacceptable!

  9. Adrienne Trice says:

    My 2020 Hyundai Santa Fe engine has been replaced twice for, check engine light coming on, burning excessive oil and misfiring on 3. I have all my documents to prove that engine is defective but it is not on the list for any lawsuits. Please help me

  10. Sherry Andrews says:

    I have a 2015 Hyundai SantaFe and Hyundai has done two procedures to try to address my oil consumption issues and today went back after them keeping my car 3 days to do a top end clean and going the required 1,000 miles only to have it down 1 quart again. I am at 85,000 miles and they are stalling until I hit the 100,000 miles so they can walk away. I am so mad. I would never buy another Hyundai.
