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.

  1. Terry Williams says:

    Just got denied by Hyundai to fix engine ,2018 hyundai tucson with 90000 mile quart and a half of oil in 1000 miles hyundai should fix there problems they already knew about

  2. Lori Hannan says:

    I started back in July of 2022 noticing my car was losing oil, at first I thought they weren’t putting enough oil when I had my oil changed, I even asked them and finally they said they wanted to do an oil consumption test, so we did this for the next 1000 miles I would cone back and they would check my oil, we did this three times and each time they had to put oil in my car. The next step was they were going to submit to Hyundai corporate well…… the service department at Terry Reid Hyundai In Cartersville, Ga did not do this, come to find out the service department manager died. In the meantime I kept calling, leaving messages and no one would return my calls when finally I went back in to have my oil changed and asked. Wesley said he would resubmit to Hyundai on a “goodwill” claim and let me know what the next steps would be. Hyundai corporate said I need to provide all service receipts done to the vehicle. I call where I bought my vehicle and they provided me all my receipts from there so I took all receipts into Terry Reid and emailed the receipts as well. Well I continued to call to make sure they had submitted to Hyundai corporate snd after two weeks of calling Terry Reid Hyundai I finally called to file a complaint with Hyundai corporate. Terry Reid Hyundai finally called me back to schedule an appt to take pictures of my engine. I dropped my car off on Monday 5.1.2023 and at this time they were going to take pictures of the engine valves, do a recall for the theft device, my check engine light was on. So I wanted to know why that was on.,,… my car was running fine. When I went to pick up my car, Tim told me that they had a list of things that needed to be fixed – the catalytic converter, spark plugs, sensors, coils – thus was about $4500. And he said that I should not be driving the car it was running very bad. I looked at him puzzled I have been driving the car, at first they said it was the gas cap.

  3. Grace Goines says:

    I am having the same issues with my 2016 Hyundai Elantra GT. Only has 72000 miles. Have cleaned the engine, flushed the fuel injection, catalytic converter, transmission serviced, every filter changed, tires rotated. I have done everything in the past year. The car still acts the same. Not one check engine light has came on. No codes to check. Have spent a lot of money. Need help.

  4. Ashley M Shafer says:

    I have a 2017 Hyundai Tucson with 69,000 miles. I went for my inspection and they checked my oil and it was bone dry. The dealership told me that newer cars burn more oil. Which I don’t believe. I have to check my oil every week which is ridiculous. I don’t have the money to pay to take it to a garage or anything. The dealership told me there’s nothing they can do.

    1. Jim Rupeika says:

      I have a 2017 Hyundai Tucson with 76000 miles – which is loosing 1 quart every 500 miles-
      Took it to the dealer – they checked it out and found that it failed the test!
      Said I would get a new engine!
      At no cost to me-
      But now their saying because I’m the second owner – I’d have to pay $3300 and Hyundai would pay $3300!
      I bought extended warranty coverage when I bought the car-
      Their checking out if it will cover it!
      I’ll have to wait and see!

      1. Delilah says:

        Will you please update us? I can’t believe what I’m reading right now after they made me feel like I was crazy when I took my 2017 Tuscon to them.

  5. Suzanne says:

    I bought a 2018 Hyundai Santa Fe sport in August of 2020. Everything was fine up until this January of 2023. All of a sudden the oil consumption is one and a half quarts per week. It’s not coming through the exhaust with black dark smoke, the mechanics say that the underneath is pristine and the seal is completely intact from when the car was manufactured. I put a claim in with Hyundai corporate and have been denied. Because I am the second owner and the mileage I am denied any help with this parent problem of excessive oil consumption. What am I supposed to do? The vehicle still running perfectly until the oil light and turns on when the oil starts getting low which is approximately 3 weeks after an oil fill. How long will it take for the engine to blow? The oil flow is going back into the engine and I don’t know what to do. Any help would be wonderful.

  6. LATOYA Cornish says:

    I have a 2020 Hyundai Tucson and it recently stalled while driving. I have 42,000 miles and had it towed to the dealership. They said utvwas a computer update malfunction. No repairs nothing now I’m worried about driving and it doing it again.

  7. Makenzie McEntire says:

    My fiancé and I purchased a used 2017 Hyundai Santa Fe Sport with like 52,000 miles on it back in 2020. Currently it has 99,000 miles, I’m the main driver and I started noticing that it had a random shudder. Then I almost messed up my car cause the oil light never came on and I found out my oil was dangerously low. Then I changed my spark plugs and found oil in one of them. I try to keep regular maintenance on it and I absolutely don’t trust my Hyundai dealership. I want in on this lawsuit.

  8. Jeni King says:

    Purchased my 2018 Hyundai Santa Fe Sport in March of 2022. It had roughly 42,000 miles on it. When I took my car in for its last oil change, I was told it was virtually empty! I have always changed the oil according to the maintenance schedule. This cycle, I had to add a quart of oil just to tide me over until it’s time for my scheduled maintenance. I’m not a mechanic, not a particularly knowledgeable car owner. So, I have no idea what is normal and what isn’t. However, I work from home mostly and my office is only about 8 miles from my home. My vehicle still has far fewer than 50,000 miles on it. It doesn’t seem right that my car should eat oil the way it does. Furthermore, I notice that it exerts a good amount of white exhaust smoke when I start it. At first I thought it might just be the cooler temperature outside. But it does it even when it isn’t particularly cold. Someone, help!

  9. Sharicka Lewis says:

    I have a 2018 Hyundai Sante Fe that consumed excessive oil. I took it to two differnt dealerships and the last dealership state they wanted to rebuild the top of my engine for 4800. No one can tell me the reason for the oil burning fast and currently had my car fow 60 days.

    1. Jessica says:

      I have the same issue! I keep oil in my car to fill up once a month. So ridiculous

      1. Cherrelle Harris says:

        Me to my trunk of my 2016 sonata has pints of oil.

  10. Nancy Nelson-bock says:

    I bought a used 2018 Hyundai Tucson in November 1922. By March 2023 I started having major problems with oil consumption I have taken to the Hyundai dealership. They said it would cost me at least $2000 for repair that may help. Has anyone fixed this issue, is there a possibility of a recall to aid in helping pay for the repairs? How do I join in on this class action suit as I am very disappointed.

    1. Shawn says:

      Yes I bout my car back in 2015 and I have ti constantly put o in my car once a week if not my car will stall. The oil light doesn’t even come on saying it’s even low I will be stuck beside the rode if I don’t have someone or myself check it once a week to make sure there is oil in car. I have had a mechanic che for leaks and nothing no where. This is just ridiculous no recalls to fix the problem or nothing this is costly on my car
