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 2021 Hyundai tuscon and I have that problem with my oil consumption

  2. Chase Hefner says:

    Also, please add me to the lawsuit.

  3. Chase Hefner says:

    My 2105 Hyundai Elantra has been having an issue the last few months where when I turn sharply, the oil light will flash. I looked online and found that it’s because the oil is low, so I started putting in a quart of oil periodically. I put a quart of oil in it about two weeks ago, but the light was still coming on. I put another quart of oil in this week and was accelerating up a highway when my car started making noises. Eventually the check engine light started blinking and I had to get it towed to a mechanic. I really, really hope that some sort of recall comes out of this because I can’t afford to replace the engine and I’m not ready to replace my car just yet.

  4. Jeffrey B Kellner says:

    Just had 2 gaskets replaced… leaking oil….sonata 2015 with 123k miles…

  5. Bree says:

    I have a 2017 Hyundai Tucson and its currently under the oil consumption test with the dealership. It only has 72,000 miles on it and I am using almost a quart every 1000 miles. I know this is not normal. Will we be notified when/if the lawsuit has been settled?

    1. Kim says:

      I’m going through the same thing right now. Hyundai is trying to find a way to blame me.

    2. Cheyanne Underwood says:

      2014 veloster, have to put 1 quart in every week. Also my catalytic converter is shot I think due to the oil.

  6. Muhammad Aslam says:

    I’m going through same problem I have Elentra 2017 which burning engine oil. I have to add oil every 1000 miles there is no sign of leak.

    1. Angeliq Vigil says:

      Me to I have the same problem I have the same car as you

  7. Nicholas says:

    Every 2000 miles I need to add one quart. If I drive 9 hours straight I need to add a quart

  8. Robbilyn Wineland says:

    I have a 2016 Hyundai Sonata and am fighting with the dealership right now. I would love to be added to the lawsuit. Their customer service has been awful and they are not returning phone calls and telling us it is normal for a vehicle to use oil.

  9. RONALD CEREOLA says:

    2017 Kia Sorento 4 cyl. turbo. 90k miles – down 2 quarts every 1500 – 2000 miles. Kia first claimed within specs, now refusing any service unless we produce every service record. Serviced by Kia for first 60k then local service stations every 5k, don’t have every record.

  10. Andrea Smith says:

    I also had this problem with my 2018 Hyundai Sonata. I can’t afford for it to break down or need a new engine parts. I am a disabled veteran on a fixed income. I bought this car expecting nothing to go wrong with it for quite a while. I am still under 100,000 miles and I am afraid I am going to end up with a $20,000 paperweight.

    1. Shane engle says:

      My daughter got a 2017 Hyundai sonata about a month ago and within 1000 miles it was empty on oil and u try to call the car lot and never get a answer
