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 excessive oil consumption class action lawsuit overview:

  • Who: A group of Hyundai and Kia vehicle owners are suing Hyundai Motor Co.
  • Why: The drivers allege numerous models of Hyundai and Kia vehicles are equipped with defective engines that use excessive amounts of oil, stall and eventually fail.
  • Where: The lawsuit was filed in a California federal court.

(April 20, 2022)

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 2014 Santa Fe SUV and just in June 13 2022 the motor started messing up and we check there wasn’t no oil in it and which the oil change was update. It has been sitting at the dealer ship for two months and I did call the corp office in regards to this and was told today (8-19-2022) since my warranty expired they would not help with the issue. It will cost 11,000.00 for a use motor.

  2. Steven Boudreau says:

    I have a Kia soul 2017 that has burned through tons of oil even with regular oil changes and filling the oil as needed. The engine has gone out and needs replacing as well as the catalytic converter. I have a quote from Kia that says these need to be replaced.

  3. Krishna Grant says:

    I have a 2017 Hyundai Sonata Sport and having the same problem. For the months of about April to June, I took my car to the dealership to have the oil consumption test done at every 1,000 miles. Each time they found that my oil levels were under. I had to pay $310 for a cleaning and in total had 6 test done. They submitted the paperwork to fix the issue and it was declined twice. So basically, I have to check the oil at least every 1,000 miles to make sure I have oil in my car. As a customer, why should this be a concern when driving my car or if anything worse will happen. Please advise on how I can be apart of this class action lawsuit.

      I had to go through this, it was a pain. They replaced my engine, but now I’m having a issue with my paint chipping and USB port stopped working.

  4. Kanisha says:

    I have a 2016 Hyundai Tucson and I have to get an oil change every 30 days because the oil in my car keeps burning out so fast.That $80 dollars every month for an oil change. I’ve been to the dealership to check for leaks and they find nothing. I don’t believe they are running or doing the right test to find out what the problem is. Nobody can seem to figure or better yet care enough to see what the real problem is.

  5. Julie James says:

    I have a 2013 Kia Soul with about 140K miles. I have been putting oil into it for months. MONTHS! At the end of my work week, before I drive to work on Friday, I check the oil. If I drive more than usual on a weekend, I check the oil on Sunday. It’s maddening! I am somewhat relieved to know that it’s not just some random, one-off defect. But Kia needs to make this right!

  6. Michael Jr Hernandez says:

    2017 Hyundai Sonata burns excessive oil like 2 quarts between oil changes.
    Hyundai you are a good company, PLEASE FIX THIS.

  7. Sunnie Ray says:

    Hey, I have a 2014 Hyundai Alandra GT with 126,000 miles on it and it burns an excessive amount of oil and it’s beginning to mess with the other parts of the car because I have to check the oil every thousand miles to ensure that they are still oil in it

  8. Twilla Jackson says:

    I would like to be added. I have a 2017 Hyundai Santa Fe Sport. It has used an EXCESSIVE amount of oil and no obvious leaks present. I have to add multiple quarts SEVERAL times in between oil changes.

  9. Nathan Hare says:

    2016 Sonata Eco. Burning through about 1 qt about every 1k miles as well. No solution offered and Hyundai is of no help

  10. Amber says:

    I have a 2017 Hyundai Santa Fe, recently had a oil pressure problem not sure if that’s the same thing but it was all of a sudden, major leakage with that oil pressure problem.
