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:

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. Sean says:

    How do I sign up for this class action? My 2014 Hyundai Genesis Coupe 3.8 Grand Touring drinks oil like it is gas. If I didn’t check it everyday, I would have blown it up by now.

    1. Jo Ann Paschal says:

      Did they indicate where to sign up

  2. Corey Griffith says:

    I owned a 2015 Hyundai Genesis Coupe Ultimate whose engine ended up seizing 6 months after warranty was up after losing oil pressure. The car would also stutter randomly when sitting at red lights. The car only had a little over 50k miles on it Hyundai quoted me roughly $8000 for a new motor or I could trade it in to the local Hyundai/Kia dealership for $7000 and be forced into signing a 7 year high APR lease. They considered this doing me a favor. Now I’m stuck in a mountain of debt with this new vehicle I didn’t want in the first place. Please help me, you guys are my only hope of getting out of this mess Hyundai has created.

  3. Rosangely Diaz says:

    Please include me. 2017 Hyundai Sonata. Excessive oil consumption at 100,000 miles. It has been a nightmare.

  4. Tiffeny Burgess says:

    Add me… my 2014 Hyundai sonata engine seized 2 days after an oil change… was told by a mechanic before towing it to universal Hyundai that the oil wasn’t flowing through and my engine was locked/done! I wasn’t aware of any engine recalls, even though I was at the dealership a month prior because my car wouldn’t start and was told it was because of my battery, but was never informed about any engine recalls when there’s a recall for my car model for engine bearing recalls

  5. Peggy says:

    I bought a 2015 Hyundai Tucson a year ago and just recently noticed that it’s burning my oil in which now I’m having to check it every 1,000 miles and add oil so it doesn’t mess up my engine and unfortunately my extended warranty doesn’t cover oil consumption testing. This is ridiculous.

    1. Peggy says:

      If possible to join the class action lawsuit, my original comment is above.

  6. Brittany G says:

    I have a 2017 Sonata that I bought brand new and have serviced religiously. I have the records to prove the ringer that the dealership has put me through with oil consumption tests that began well under 100k miles. It burns about one quarter per 500 miles. They have given me the absolute run around, blamed me, lied, you name it. Again, I have a massive paper trail. This has taken place at SanTan Hyundai in Gilbert, AZ, but beyond that Hyundai motor company has failed to step up and make it right.

    1. Rosangely Diaz says:

      Same issue I am having. Hyundai dealerships are useless my Sonata is doing the same thing.

  7. Karla D Marquis says:

    I purchased a 2017 Hyundai Sonata from Centennial Hills Hyundai in Las Vegas in March/2022. No warranty because of mileage but I was assured a 126 point inspection was done and no problems. Started noticing excessive oil consumption and had to keep replacing oil about every 200 miles. Had an oil change done week of June 11, 2022 and five days later engine caught on fire! Declared a total loss by my insurance company. This is criminal!

  8. Steven McVey says:

    I have a 2017 Hyndai Tuscon. In May 2022 the car started burning a quart of oil ever 700-1,000 miles. It has gradually gotten worse. I took the car to G&G Supercenter in Dodge City, KS. They are the Hyundai dealer. They had the car over a month. The performed the recalls but it made no difference on the burning of the oil. The car has gone in to limp mode or engine protection mode. It does not accelerate very well and has no power at all. They told me the car was fixed but still it made no difference. The car has 112,600 miles on it now. Hyundai Motor America denied the warranty claim because of the mileage and the fact I didn’t have every maintenance record since I purchased the car. I sent it to my Extended warranty which is Route 66 and they denied it because Hyundai denied it. Now I have been without a car well over a month and have to pay for this repair on my own?? This just is not right. I took it to a certified mechanic that told me this is the typical problem this year of Hyundai Tucson is having. It has nothing to do with maintenance or lack thereof. I have always been good at keeping the oil changed on time in all of my vehicles. I would love to see what it takes, if possible, to join the class action law suit.

  9. Haylie McFarland says:

    I just purchased a 2018 Hyundai Tucson and it ran completely out of oil after supposedly just having an oil change. How do we get more information about joining?

  10. Keva Savage says:

    I have a 2015 Hyundai Sonata that recently started burning oil like crazy, had to add 4qts just yesterday and my light doesn’t even come on anymore for it. Just got my oil changed 2-3 weeks prior as well
