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.

    I have a 2015 Hyundai Tucson with the same oil consumption issue.

  2. Christopher D Monti says:

    I have a 2017 kia optima and have the same issue with oil. Supposed to last 5000 miles. Barely makes 2500 before oil black. Also need a new oil pan. There’s a default in the pans but of course kia/Hyundai won’t pay. Never again with kia. Just waiting for the engine to go now.

  3. Tina says:

    I live in Kentucky and drive a 21015 Hyundai Sonata. I started noticing how much oil my car was going through when I started driving a hour to work everyday. I had an oil consumption test done and the guy told me I could spend $6000 on a new engine or just keep adding oil. This is ridiculous. When I called the Hyundai dealer they said there is no recall on the vehicle. Is there anything I can do?

  4. María Ortiz Martinez. says:

    I .am heart broken. I love in Puerto Rico. I.finally had sabes to Buy a used 2018 Kia Río. ,It’s burning oil like crazy. Twice I had to change the Upper oxygen sensor . Today It went on again 😔. And Is slughidh. When I stop.st a street light iWhem I put My foot on the.gas it doesnt move and turnd off. When I Star it again. Is fine until I stop.sgsin 🥲.

  5. Shahab Nazari says:

    Our car is also over consuming oil. I brought the car after 1000 miles driving it and they said you consumed only .75 a qurarter and so you do not have over consumption. While at 2000 miles definitely car runs out of oil. So they denied my claim. What an irresponsible company is Hyundai? They are taking their market for granted in the USA. They need to be thrown out of the USA.

  6. Dona Hayes says:

    I have a 2017 Tucson Eco that has been burning oil for about a year and it’s back at the dealership today for the next part of the oil consumption test. It’s been nothing but aggravation and complications. They have tried to blame the oil loss on everything from leaky gaskets to a faulty turbo even though I have told them repeatedly that the oil is burning, not leaking. When I check the oil about a week after it’s been changed, it’s black. I was initially blaming the dealership but now I see that it’s a much bigger problem with Hyundai itself. I liked my car before all this started but now I know I will never buy a Hyundai again.

    1. Mad in Maryland says:

      We got the same run around! Do this and that. It needs this or that… when it’s OBVIOUSLY a fault with the product but Hyundai KNOWS they will go bankrupt if they admit fault so they keep trying to blame us consumers or wear and tear. Absolutely ridiculous!

  7. Hope D Johnson says:

    My car is losing a lot of oil. Paid 1500 to get it fixed and I am still having issues.

  8. Nate J. says:

    Located in Virginia Beach, Virginia. In 2018, I bought a used 2013 Hyundai Elantra GLS at a dealership at 68k miles and had no issues with this. Was totaled 3 years later (I was found not at fault) and taken by my insurance at 122k miles. Still did not have that issue at the 122k mile mark. Now my 2012 Hyundai Accent hatchback that I got after that accident as a used car at 87k miles, at another dealership – one year later at 95k, learned and realized that the car was burning oil and apparently had the oil consumption problem too. I declined to participate in a costly oil test with Hyundai as one is not stupid to know when it’s burning oil. To remedy this per Hyundai, you will need to have them build a new engine and purchase that engine and have them install it in the car. At this point, at $10k+, you are far better off just buying another car. Swapping out this vehicle during the 2024 year. I would recommend staying away from a majority of Hyundai vehicles.

    2019 Kia Optima burning through oil like milk on a Saturday morning. I’ll tell you this much, Kia Cares, doesn’t care!!

  10. Faetris Taylor says:

    I Have a 2014 Hyundai Santa Fe Sport that burns a lot of oil Hyundai has denied my claim over and over then finally my engine went out and they replaced it for free. However, the amount of money I have spent is ridiculous. Even with engine replacement Hyundai has failed me a customer and many more. I have filed multiple compliant over and over with noting being done about it
