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. Imelda Vigil says:

    I would like to join the lawsuit. My 2014 Santa Fe Sport left me stranded on the freeway yesterday with my Grand child in the vehicle I was afraid we were going to be killed on the freeway. I had the vehicle towed to the mechanic shop and they told me that the engine is burned out due to no oil and I recently had gotten an oil change and very frequently the oil light comes on letting us know that oil is needed way before the time that an oil change is needed. Over the last 18 months I’ve probably put in close to $7000 in repairs due to all of this. The mechanic shop is suggesting a new engine or sell the vehicle as is. It has about 125,000 miles on it and the warranty is no longer in effect.

  2. Jeffrey DeCook says:

    I have a 2015 Elantra GT. The car is burning oil and all the dealers offer are oil consumption tests which would cost $900. They told me most likely I would have to replace the engine which would cost me $6k-$7k.

    Hyundai refuses to cover this repair. What an absolute joke and ripoff.

  3. Derek Newberry says:

    I have this issue on my 2016 hyundai sonata sport. The oil light is contantly going on and off, and needs an oil change completely every 1400 miles. Please include me in this suit.

  4. David Romeo says:

    My car is a 2016 hyandi elantra and has this problem had for almost a year and changed oil twice since had car only have 53 200 miles on it got it with 46 000 from timebuyer here in Cortland ny

  5. Irene Will Clute says:

    I had a 2013 Elantra that burned oil, had engine light issues no one could diagnose. After spending thousands on repairs and still had more and more problems, I sold the car for a loss.

  6. P Lamb says:

    Oil light flashed on and off on my Hyundai Tucson 2017. We checked oil, shows no oil. Hyundai told me to have towed in, they checked out and added 3 quarts of oil. From reading all of the post, I feel like I need to trade in tomorrow. Please include me on correspondence.

  7. Charmaine Bey-Brody says:

    My 2016 Sante Fe is burning almost 2 quarts of oil a week. I had it serviced in June for the same issue. The said it was the valve cover and the catalytic converter was damaged. $3100 later. Now here we are in October and it’s burning oil again.

  8. John Flaherty says:

    My 2017 Tuscon isaffective by excessive oil consumption. Just comleted the test at my dealer, and despite burning through 1.75 quarts in the last 1,000 mile testing increment, the dealer says this is normal and within spec. The vehicle required a replacement catalytic converter6 months ago and the exhaust system now has a defect that requires repair.

  9. Mckenzie Hamilton says:

    I have a 2018 Hyundai Tuscon and it needs a completely new engine due to this issue. The engine has since been “discontinued” and they will have to build me a new one which will cost more than what I owe on the car. But I also cannot trade it in because it’s basically valueless since it needs a new engine. Warranty company doesn’t want to fix it since Hyundai is claiming there is no way to determine what caused the issue.

    1. David says:

      My 2015 Sonata sport has had extremely oil consumption problems. I have kept up with all oil changes compliances, and won’t last 200 miles before have to add more oil. Hyundai tells me I have to pay $1000 for them to check oil consumption, and won’t guarentee Hyundai will cover it if it’s causing problems with engine.

      1. Phyllis says:

        I was told my car was fine. I am so afraid my vehicle will catch fire. I check my oil once a week and replace what has disappeared.

      2. Kelsey says:

        I have a 2016 sonata sport and I have been suffering with oil burning fast for about a year or more now. It used to be reset at 5,000, and when I hit 2,000 left, I would have to go in for an oil change. But as of today its at 3,500 left and now when I turn my car, oil light briefly comes on. I have 138,000 miles on the car and never had any internal issues since I bought it. Called and they will look at it for free but no promises its covered. Idk what to do.. I think we are all screwed. My car also lags when I stop then press the accelerator.

  10. Gwen Rivera says:

    We have a 2017 Hyundai Santa Fe. My husband just checked oil and it doesn’t register any oil on dipstick, and no oil light came on. We are in the process of getting it checked.
    We would like to join the lawsuit. Any info on this would be appreciated.

    1. Fred Hammond says:

      Oil consumption is now a quart every 500 miles or less.
