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 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. James Harris says:

    I own a 2017 Hyundai Tucson Limited. I bought it brand-new. I went to Hyundai and mentioned this class action lawsuit to seek an engine replacement when my car had about 120,000 miles. This was around July 2022. Hyundai made me jump through a bunch of hoops which I did. I did 3 oil consumption test with them. After completing their test, we found out that my 2017 Tucson was & still is burning about 1.4 quarts of oil per 1000 miles. They even took my engine apart to make sure there wasnโ€™t sludge buildup. (they were trying to find neglect)

    It was squeaky clean and they still denied me! Even the tech-support agent that was helping me was extremely surprised that they denied me. He thought for sure that I would be getting a new engine.

    Hyundai said that they felt in their opinion that I may have neglected to follow regular maintenance, which is not true. I only put full synthetic oil in my Tucson and always followed their regular maintenance schedules for oil changes, TuneUps, air filter replacements, etc. I scrounged up as many service records as I could find (and I had a bunch), but because I didnโ€™t have every single service maintenance receipt dating back to the day I bought the car, they denied me.

    My car had about 120,000 miles when I went through the oil consumption test. However Iโ€™ve called Hyundai several times well before my warranty was up and asked him if there was a recall, because of the oil consumption. They always said no recalls. This dates back to when my car only had 60,000 miles on it (when my car was only about 3 years old). Iโ€™ve been topping off the oil every 1000 miles or so ever since then. My experience with Hyundai has been terrible, I will never buy another Hyundai in my entire life.

    Unfortunately, Iโ€™ll end up trading this car in (while itโ€™s still running) before any class action lawsuit or recall happens.

    Yes, please keep me posted! This is a real problem, and expensive too!

  3. Jessica says:

    YES!!!! I am constantly having to top my oil and already had to replace a gasket. If anyone has any info on how to join the lawsuit please let me know.

  4. Scott says:

    2013 Sonata. Oil needs to be added after virtually every trip. Estimate a quart every 300 miles

  5. Jorge Tobar says:

    Yes. Burning oil. How can I join the lawsuit?

    1. Christine says:

      I am currently going through this right now and the Hyundai dealership is denying any fault and in fact wants to charge me to have my engine replaced and the catalytic converter is also plugged with over 16 PSI from the burning oil. We need to all stick together and file another law suit. IF they are not going to stick to their word we need to make them!

      1. La Tasha Hawthorne says:

        Currently going through my 3rd go around with this issue in less than 2 years. How do I join this lawsuit?

  6. Julie says:

    My 2011 Hyundai Sonata is also burning oil excessively, except itโ€™s not on the list (only 2009-2010 and 2015-2021). I donโ€™t drive this car around a lot, I maintain/service and take very good care of my car. I am always having to top it up with oil. Does anybody else out there have a 2011 Hyundai Sonata that isnโ€™t included in list but having all these same issues?

  7. Don Straight says:

    Can someone contact me on how to join this lawsuit?

  8. Jeff Polet says:

    2017 Elantra, started consuming oil at about 40,000 miles. Using about a quart for every 1500 miles. Did all the interval tests and Hyundai dealer said โ€œnothing we can do. Itโ€™s within tolerable limits.โ€ Really? If I have a brand new car and itโ€™s using 2 quarts of oil between changes, thatโ€™s tolerable? I have been begging Hyundai to take care of this problem.

  9. Meggan Flanagan says:

    I have a 2017 Tucson and currently doing the 1000 mile drive so they can tell where the oil is going. Looks like they already know. They sent me off with little or no oil last week from dealership after bringing it in for my engine light blinking. I could tell it wasnโ€™t driving right and called immediately. Light back on, towed back there and they said no oil and tried to blame me! How can Texas drivers get into this lawsuit?

  10. Matt Moeller says:

    My 2016 Kia Sorento has around 75000 miles and found out after oil consumption test that it failed. Since Iโ€™m the third owner (but has food maintenance record) Kia wonโ€™t pay for the engine cleaning. Burning at least a quart of oil every thousand miles!
