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.

  1. Sandra Tullo says:

    I have 2015 Sonata Limited. Have been losing oil for several years now. I’ve been told that it’s a “thing” with Sonatas but nothing to be done. Have to check and add oil regularly.

  2. Roberto Perez says:

    I own a 2017 Hyundai Tucson with 38000 miles, it has been at the dealer twice for the oil consumption test but according to the dealer they found no issues, I check the oil every week and top it of as needed it seems to be about one quart every 1000/1200 miles. They want to run another test to see if anything has changed, what a shame that they can stand behind their vehicles and do right.

  3. Laurel hart says:

    We have a 2017 Hyundai Santa Fe and are going through this now. After seven months of going into Hyundai every 1000 miles to check the oil they have determined that we are burning 1 quart of oil every 550 miles. For any lengthy drive we now pack oil and check with every gas fill up. We just passed 100,000 miles. Unhelpful and unwilling to resolve this claim that rose while the car was under warranty. They continually close the file which makes me afraid that they will eventually say this arose after the warranty

  4. Emily Sommerville says:

    I have a 2018 Hyundai and I’m putting oil in my car every week. Bought it brand new and kept up with the vehicles maintenance. The oil just burns up.

    1. Shawn says:

      I’m going through this with my 2018 Hyundai Sonata also. It’s constantly burning up oil

  5. Nathan Crusan says:

    I have a 2015 Hyundai Sonata with oil consumption issues. I went for an oil consumption test and was told that my Sonata is burning one quart of oil per every thousand miles but Hyundai would not honor the warranty because it was not consuming enough oil

  6. Dean says:

    I have a 2017 sonata limited with under 50k miles. I went to the dealer for the trunk recall after it wouldn’t latch. To my surprise I was told my oil was low. I thought there must be a leak, I use only synthetic and drive only 2800 miles. I needed 3 quarts to get back to normal !
    Now i’m worried about the amount of wear and tear to the engine. I will have to be in top of my oil checks from now now and hope that This is somehow addressed by Hyundai.
    I’m glad I read this article and have a better understanding of what is happening.

  7. Aubrey Hampton says:

    I have a 2019 Hyundai Sonata se and I burn a quart every thousand miles. The dealer said this is normal it is not. Please advise how to become apart of this lawsuit.

  8. Greg Melton says:

    I have a 2015 Hyundai Sonata sport and it uses about a quart every 1000 miles and seems to be getting worse. I have heard about this and have done a lot of research. I took it to the dealer to do an oil consumption test and they said Hyundai will not cover ithe test since I am a second owner. I bought it in 2017 with 25k on it. This is ridiculous ….so how do we join the lawsuit?

  9. Yolanda Davis says:
