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 similar issue with 2013 Sonata SE. Went to dealership but wanted to charge $180 for diagnosis even at the request of customer service. . I provided case # but didn’t help in any way with the situation. I will have to contact customer service again and setup another appointment.

  2. Melissa Holloway says:

    I’m at Valvoline right now getting my oil changed again I put oil in my car all the time. I have a 2019 Hyundai Sonata My oil light comes on a week after I get an oil change or days after I just add oil. I would love to join the lawsuit

  3. Anita says:

    I have a 2016 Hyundai tuscan I bought an extended warranty. My car is burning oil and going to my Converter. They done an oil consumption test I been waiting over 6 months and now they want me to pay out of pocket a cleaning to my engine which they will not reimburse if they engine needs replaced. I have to put a quart of oil in a week this is just not right at all.

  4. Doyle W Morse Jr says:

    I bought my 2014 Hyundai Elantra GT brand new (and still own it today) from Allen Samuels Hyundai in Tyler, Texas. Over the last 3 years I can not figure out WHY after having the car’s oil changed at the Service Department for Hyundai in Tyler that after about 400 miles later the car is nearly OUT of oil completely. Since the car was new it has ONLY been dealer serviced with maintained records of receipt for all the work that has been performed. The car nearly has 137k miles on it all driven by me. I was just about to go back to Hyundai next week and ask the service advisor WHY this keeps occurring ? I was just speaking to my elderly Uncle about me having to check the oil in the car like every other day and how annoying it has become. I am a 54 year old male and have taken excellent care of the vehicle and have EVERY SINGLE piece of documented receipts and paperwork since the car was new. I just stumbled across this while searching for historical Tyler, Texas items and some how this mysteriously came up under the images and I clicked on the information. Happy I did.

  5. Stevie Lemon says:

    The details of the lawsuit is exactly what I am experiencing with my 2015 Sonata. The engine is burning oil. I must put in more oil than the owners manual requires. My car stalls (hesitates often) and sometimes my car will not accelerate. A local mechanic recommended that he change my spark plugs out because oil had seeped in their compartment.

  6. Lamar Davis says:

    I purchased a 2016 Hyundai Sonata for my daughter 17th birthday at the end of January. Borrowed money from bank to pay the dealership. By May I my daughter’s oil light came on. Since then we have put a quart of oil a week in it. I purchased a fraud extended warranty from US Automotive. Now I have a car note and a car with a motor tht could go at anytime. If anyone knows anything I can do to slow down the oil leak please let me know.

    1. Anita says:

      And Hyundai wants 600 .00 for the cleaning and oil test

  7. Jamie J Mueller says:

    2016 Sonata burning oil. 90,000 miles. I have been taking my vehicle to a local shop but they can’t figure it out. I will be taking it to a hyundai dealer.

  8. Kristen Wilson says:

    2010 Hyandai Sonata owner. Took car to get inspection and was told there was no oil in the car after just having the oil changed a month ago. Tech told me it’s an existing problem with this make model. So, how are people being allowed to sell them and no info on Carfax about it?!?!!!

  9. Jessica says:

    2018 Hyundai Tucson same issue! Was told passed oil consumption test 11/10. Broke down 12/19- engine misfire & no oil at all in my car. Service manager told me today my options are change oil every 1,000 miles or trade car in!! Been dealing with this for over a year. Sickening

  10. Blanca Rios says:

    2015 Tucson and I have been dealing with this exact issue for over a year. Hyundai says it’s absolutely normal and won’t help. We’ve had the car stall twice and turn off in the middle of the road
