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. LARONDA CORRIN says:

    2017 Santa Fe Sport. Having to add oil constantly and at one point it was almost completely empty and no pil or engine light ever came on.

    1. Elizabeth Vasel says:

      Same here

  2. Rochelle Mccarthy says:

    We have a 2016 Hyundai Tucson and 2016 Hyundai Sonata with excessive oil consumption. They both will consume all the oil in between oil changes. The dealer says we have to pay to have a list of services done before Hyundai will help us. This is not right.

  3. Diana says:

    How can I be added to this class action suit. I have a 2016 Santa Fe Sport and it has begun burning oil at a rate that is much too fast, and the engine smells like burning oil. I live in Texas. There should be some recourse, if nothing else than to honor the repairs as warranty work.

  4. Lynn Keller says:

    I have been dealing with this with my 2018 Sonata, when it was fairly new they once told me it had hardly had any oil left when i went for an oil change….I went every 3000 miles, i told them well it must be your mechanichics not filling the oil….come to find out….it has been over consuming all along since i bought it brand new…. Dealership wanted me to believe that it was normal to consume a quarter of oil every 1000 miles… I am now in my 2nd oil consumption test

  5. Barbara says:

    I have a 2016 Hyundai Veloster, I keep up with oil changes faithfully.. I have had to call the dealership twice about my oil light coming on before the next service date / mileage. I would check my oil and there wouldn’t be any oil in my engine. I have had to purchase oil until I could get into the dealership. It happened again last month. I called the dealership because I was a bit upset that it happened again… the no oil and I had driven 45 mins from my job to my doctor appt to see my oil light flicker, pull into a auto parts store , check my oil and it was empty. I could have blew my engine up. I called the dealership and spoke to an employee that told me that there is a recall on the motor due to excessive oil burning.. I would like to know what I need to do regarding this lawsuit.. definitely can’t deal with engine issues. Please inform. Thanks.

  6. Michael Blackmon says:

    Mine is using oil like crazy also. 1 quart every 300 miles or so. They need to do something for sure.

  7. Angela Mack says:

    I have a 2017 Hyundai sonata and have had to check my oil every 500 miles. Told the dealership about it numerous times when getting oil changed. Was placated like I didn’t know what I was talking about. Then the engine derated and stalled on interstate. Got it started again and took it to dealership. Told nothing was wrong. I just needed a computer update. When I asked them about the fact that the oil light never came on. Was told it wouldn’t until it was too late. It failed a consumption test. Hyundai won’t honor lifetime engine warranty recall or failed oil consumption test. But out of good faith they’ll cover 50% of engine replacement.

  8. Keelan Gonzales says:

    I have a 2015 Tucson that has apparently been going through oil, w/o me realizing, I had no light indicator come on or any signs until i was driving yesterday and all of the sudden I had extremely loud noises coming from my car. Pulled over and sent audio to a mechanic, stating it sounded like the engine is failing.. to check the oil.. well it was empty, and this is after a recent oil change where no leaks were found.. I am now left w/o a car. How do i get involved in this claim? I am in Arizona..

  9. Mary Sparks says:

    I have a 2019 Hyundai Tuscon a mechanic and Hyundai have both verified I need an engine replacement due to the oil issue but Hyundai is only willing to cover 80% so my out of pocket cost is $2000. Hyundai should be responsible for 100% as the issues my car is having is not fault of my own. Its 61,000 miles and I have had it for 2 years. I have opted to reach out to the attorneys handling the lawsuit and see if they can help me

  10. Tamara McCauley says:

    I too have a 2015 Sante Fe, that I love!!! But now what do I do?? Just found out it is consuming a quart of oil every 1000 miles. This is very upsetting. 130,000 miles.
