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. Eric Ouedraogo says:

    I have a 2017 Sonata, and I have been looking for a solution how to fix this problem. Glad there is a civil suit. Count me in.

    1. Barbara Wallace says:

      I also have a 2017 and it has been a pain since I got it please help I can’t afford it any longer

    2. Luis Plata says:

      I also have a 2017 hyuandai sonata. The past couple months my engine oil has run bone dry very quickly. With no visible leaks or the smell of burnt oil. Very frustrating.

    3. DeeDee says:

      I have a 2017 Sonata Limited. Has been a fantastic car. In the last 6 months, my oil light is coming on randomly and when i check the oil, it is dang near dry. The first time this happened i took it for the oil change and was told it was a broken gasket. Next oil change, light is coming on more frequently and i had to put oil in it 3 days before my appointment. This time i was told that some engines just use more oil. I only have 64,500 miles on it. So, no it should not be doing this.

  2. Maisha Clark says:

    My uncle just happened to check my oil and it was empty. No oil light. I had an oil change and they found no leaks. So I just paid them 179 dollars for an oil consumption test which means I need to bring in my car every 1000 miles. I’m so happy I saw this as I had no idea this was a thing. First and last Hyundai.

    1. Lori Nanfeldt says:

      So they charge you for an oil consumption test? When i go pick up my Sonata I will be asking about that. I am not going to pay for a test that is being caused by Hyundai engines defects.

    2. Terry Stevens says:

      I own a 2017 Hyundia Elantra. Only 85,000 miles. For past 2 months car misfires, has lost power, has died at least 5 times while driving and had no oil on dip stick a month after oil change. Have replaced 2 coil packs trying to correct misfires. Check engine light came back on. Car is getting harder to start. Went to dealer where car was purchased 11/16/2022 and requested a diagnostic test be performed. Was told they could not service car until January, 2023. What are we supposed to do. The car is unsafe to drive. Please include me in Class Action Lawsuit.

  3. Lee M. says:

    My 2016 Kia Sorento EX 3.3L Lambda V6 seems to have this problem. No warning signs or idiot lights, paid the final car payment, and the car shut down in motion, seems to have no oil in it. My wife was able to roll from the point of stall to our driveway, thankfully all downhill. I got it started the next day, and rapidly turned it off due to blown engine sounds. Have always changed oil on schedule, still had ~500 miles to go on this one. Haven’t taken it for repair yet so as to step carefully in light of the potential legal ramifications but it doesn’t look good. Planned obsolescence is really a state of the art science these days!

  4. Robert Ramage says:

    I am in the same boat as all of the above owners. I have a 2016 sonata se. Just now turned over 100k miles on it. Been using oil for last 20k miles or so. Have done regular service every 3 k miles and have had all recall services done that I have seen. I have replaced pcc valve and valve cover gaskets and cleaned intake for carbon build up as thought that may be the issue but still using 2-3 qts oil between service. Count me in on the law suit as well.

  5. Vikki M says:

    My 2016 Hyundai Elantra gt uses about 4 qts every 5000-7000 miles. 3 months ago I had to replace the catyliic converter and valve cover. I am so frustrated, it has 150000 miles.

  6. Jessica Gonzalez says:

    2018 hyundai Tucson burning oil very fast …causing engine trouble

  7. Christina says:

    I have a 2015 Hyundai Sonata Sport Turbo 2.0T I noticed my oil light blinking. It wasn’t time for an oil change yet. So I checked my dip stick couldn’t believe my stick was bone dry. I always get my car serviced at the Hyundai Dealership where I purchased my car. They are the only ones under my hood. I called the service department to let them know my oil dip stick was dry and it’s not time for a oil change yet. They had me bring in my vehicle to check for oil leaks nothing leaking. They changed my oil and came back to tell me my oil is burning. There’s a civil suit on engine burning oil. So how are we going to fix this. Every 2,000 or less Miles I have to buy oil for my car. The manager told me I have to constantly check the oil stick. What!!!!! I pay them to service my car. The manager told me I have to check my own oil. Until they hear something about the civil suit. This never happen to me before. Please count me in . Add my name to the civil suit for me. This is the First!!! I hope this will get resolved real soon.

  8. Mary Waters says:

    My 2016 Tucson is doing the same thing! it burns oil so fast I cant keep up with it
    I carry oil with me at all times. i bought this car used and I assume this is why the shoved the extended warranty down my throat!
    I want in on this lawsuit I financed this and still owe for 5 yrs on something that’s not going to last probably another month!

  9. Lisa Lere says:

    2015 Hyundai Santa Fe, burning oil. It’s still under the 100,000 mile warranty and it’s been a nightmare jumping through all their hoops trying to get answers and the problem fixed. It’s literally been months. This is our 2nd Hyundai vehicle and definitely will be our last. The customer service absolutely sucks, and obviously the vehicles aren’t being made as well as expected. Currently sitting here at the garage for yet another consumption test or whatever they are doing. All I know is my car is burning a lot of oil and they are absolutely jacking us around. Very disappointing. Why is fixing the problem such an issue ???

    1. Sara C says:

      I recently ran into this issue. Thought it was a fluke or something with my oil change.. I’m only at 119k miles. The first time my oil was low just a month ago, I thought maybe they didn’t fill it up with the amount needed. Then Last week, only 2600 miles after my previous oil change, nothing on my dip stick!! I had to add 4 qts only a month later! Hyundai said the same thing to me, “They would do an oil consumption test”. Something has got to be done. Long process and we will probably not get anywhere with this.. blows my mind.

  10. Chris Cochran says:

    My oil light flashed today for the first time ever on my 2017 Hyundai Santa Fe. I took it to get the oil level looked at. I had just had it changed 1,000 miles ago and just found out it had burned 3 1/2 quarts of oil. Just googled the issue and found this website and that there is this lawsuit.

    Two weeks ago we bought our daughter a 2018 Hyundai Sonata and now find out about this issue.
