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. Lynne M McNutt says:

    Found my 2016 Sonata without oil at 75,000, 5,000 miles after my last oil change. Added synthetic and drove another 8,500 before this oil change. Service center told me about the oil burning problem, told me the only way to fix it is a new engine, and I looked it up to discover this site and it’s bad news. This is my third Hyundai, which I had hoped to keep for several more years bc income is fixed and the car is paid off. Hyundai should make it right and soon. Add me to this class action!

  2. Debbie Terwelp says:

    I own a 2017 Santa Fe I had purchased certified used from dealership. I have to check oil every 1000 miles or so. Hyundai dealership denies anything is wrong! I have had occasions when doing oil change at service stations that no oil is in engine when draining! I don’t know what to do! Please add me to class action suit.

  3. Steve Huster says:

    I own a 2013 Hyundai Sonata. Back in August of this year 2022, I noticed I was burning more oil. I had 110k miles on the new engine. I called Hyundai to have it serviced. They told me they couldn’t get me in until the last week of November. I needed the car since I drive a lot for my job. Last week the problem has got out of hand. I’m burning a quart ever 600 miles. I called again and they told me they couldn’t get me in until the 3rd week of February, 2023. I’ve always the warranty book and service requirements. So do I take a chance and keep the car until the end of February; Knowing that the car might not make it that long or do I try and sell it for a lower price and pass my problem onto someone else?

  4. N DuFour says:

    This is happening to my 2015 Hyundai Tuscan! Every time I go to get an oil change my oil is bone dry. The mechanic said it’s a “known issue” with my vehicle!! Fix it!

  5. Zena Castillo says:

  6. Dave Mitchell says:

    I own a 2017 Hyundai Tucson sport. In between oil changes I have been adding 4-6 quart’s checking for leaks and checking exhaust I haven’t found anything so oil going somewhere. This needs to be addressed asap. I am financing the vehicle if the engine goes banks still want their cut. This isn’t right issue recall get the issue resolved that’s the right thing to do.

  7. Rachel Wahlrab says:

    I own a 2017 Hyundai Santa Fe Sport. I just took my vehicle in to get an oil change at a Jiffy Lube, and the gentlemen were telling me all about this. He showed me that I had no oil and that it there’s oil sludge. I was shocked to say the least. I haven’t had any issues with my vehicle (thankfully!). Now that I’m aware of the issue I’ll need to keep tabs on where my oil is at once a month. I’d hate for something to happen, but now it’s going to be a little annoying. I will say I learn something new everyday. 😵‍💫

  8. Tysheanna House says:

    I have a 2017 Hyundai Accent. I have to put oil in there constantly after 1 month.

  9. Rachel Shoumaker says:

    My 2017 Hyundai Elantra was stalling and dying- no oil ended up being the issue. I have to get an oil change every 2500 miles to prevent it from stalling. I went over by 200 miles and boom, yesterday it stalled.

    1. Raymond Mitchell says:
