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 automakerโ€™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 hasnโ€™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 ownerโ€™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 shouldnโ€™t be, damaging the combustion and exhaust systems.

This allegedly causes โ€œabnormal wear of engine parts, oversaturation of carbon and deposits of oil sludge, ultimately requiring a costly engine rebuild or replacement.โ€

Automaker should honor warranty claims outside terms, Hyundai class action says

The plaintiffs allege that Hyundai should honor customersโ€™ warranty claims even when the warranties have expired.ย 

According to the lawsuit, Hyundai canโ€™t adequately repair the oil consumption problems and doesnโ€™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, โ€œand in most cases do not receive required engine replacements.โ€

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, 2011โ€“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.ย 

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. Harry Richardson says:

    I have a 2016 Hyundai Elantra, with only 77197 miles have had to change the oil pan gasket twice recently. Came home from work yesterday checked my oil and the dip stick was dry. The Service Shop I use is a reputable company and has done work on my other cars with no problems. How do I become a part of this law suit as well? I live in Texas.

  2. Bob says:

    We purchased a 2013 Sonata limited with the 2.4. Once it hit 140 k it started using a quart of oil a week, it stalls while driving occasionally, the dealers says do an oil consumption check so I do one every week now and have to add oil or risk blowing the engine and being out a 29k car?

  3. Richard says:

    Iโ€™m sitting in the dealer right now, they replaced my engine 6k miles ago on my 2012 sonata because it died due to the they recall. Now in is burning a quart every 300 miles on a brand new engine, and corporate is saying that they will not do anything. On a brand new engine, they just installed.

  4. Tiffany Kendon says:

    I have a 2015 Hyundai Tucson the oil consumption is through the roof. How do I become apart of the suit?

  5. Bill Henrichs says:

    Our 2017 Santa Fe SE just had catastrophic engine failure

  6. Tammy Holmes says:

    2. VR says:

      I have a Hyundai Tucson Limited 2015 with the same problem. Please let me know asap how that I can add me to the suit. Thanks!

  7. Theresa Schoonover says:

    I am also having the same issue with my 2017 Hyundai Sonata Limited. Burning oil to the point I have to check it every two days. Any advice on how to join the lawsuit?

  8. Kimberly says:

    I have a 2017 Hyundai Tucson and replaced the engine at 73,000 miles even though hyundai admitted my car had a defect but they would not fix the car because I was not the original owner. I am now at 120,000 miles and my engine blew through its oil again and I fear I will need to replace my engine AGAIN!

  9. Sonya Boyd says:

    I am the owner of a 2018 Hyundai Tucson and I have been having a lot of issues with my oil. I have had my catalytic converter replaced, I have had several oil consumptions test done by Hyundai only to to be told that my oil consumption is normal. I am outside of the warranty as well as some other consumers. I am constantly having to check my oil and have it topped off because it continues to burn oil. Something has to be done. This is not safe!!!!

  10. Deborah Jones says:

    My 2017 Hyundai Sonata is doing the same thing and the dealership keeps having me bring it back every 1,000 miles to check the oil then they add a quart of oil tell โ€˜me to come back in another 1,000 miles. It had 56,000 miles on it when this started. They are telling me per Hyundai standards that this is normal
