Hyundai excessive oil consumption class action lawsuit overview:

(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.

  2. Ricketia says:

  3. diane gillespie says:

  4. Billie A Carpenter says:

    I have a 2016 hyundai veloster the oil runs out every week I have to keep adding oil was told it was the engines design to use more oil also my headlights blow like every 4 weeks or so worst car I have ever had

  5. Randy says:

    I bought a 2017 Hyundai Sonata Limited with like 49000 miles on it. After a few weeks, I checked the oil and to my surprise it was down a little over 2 quarts. since then its been like a quart a week then 1 1/2 and then I had a coil go bad, then a plug foul because my mechanic tells me I have oil being blown out past a now damaged piston ring and said it will continually get worse until the cylinder is ruined and the engine dies. I still owe almost $7000 on the car and it would be a lot more but I have been putting everything I possibly could on the car. Now I canโ€™t drive it and I canโ€™t afford an engine. What do I do?

    1. Christie Marsh says:

      I have the same car and owe $15000 on it. It is clattering and not wanting to run! Have to put oil in it every week

  6. Jeff Taylor says:

    We bought a 2017 Hyundai Santa Fe ultimate 2.0 Turbo about 6 weeks ago. It is a very nice vehicle with approximately 96,000 miles on it. We bought the car from a reputable dealer in Charlotte North carolina. I have not checked the oil since we purchased the car, which was sort of dumb on my part, but for some reason had a premonition to check it yesterday. When I checked it, there was not any oil touching the dipstick. I was shocked. So, I added a quart figuring that it would bring me maybe between the two marks on the dipstick. It did not touch the dipstick with a quart so I wound up adding two more quarts and it barely touched the dipstick. I went up adding a grand total of five brand new quartz of oil to bring it up to the full level. I am completely shocked and baffled by this. Iโ€™ve been driving a car with no freaking oil in it! Thereโ€™s no telling how much damage has been done to this engine. In fact, Iโ€™m surprised the damn thing didnโ€™t blow up. Not sure what my remedy is at this point but I will pursue it in a vigorous manner.

  7. Alissa Brewer says:

    I have a 2017 Elantra and have issues with the oil consumption as well as stalling. Carried backed to dealership twice and was charged over 1000 dollars and my car still has issues. Went by the dealership today and they finally told me what the issue was and they were not going to do anything since it was pass the 100,000 mile warranty. I said so you charge me 1000 dollars knowing it was not going to fix the problem! Hyundai is horrible!

  8. Jeff L. says:

    Yes, Iโ€™d like to be part of this class action suit as well. Owner of a 2015 Hyundai Santa Fe Limited, just passed 125,000 miles and needs a quart or two of oil between oil changes now. Iโ€™m the only owner of this vehicle, leased-then-purchased.

  9. Angela Fountain says:

    We have a 2016 Hyundai Tucson that all of a sudden started guzzling oil. Then on a trip home from vacation the car died. We towed it to Hyundai and after 3 months of no communication ( with us reaching out numerous times) we were told Hyundai refused to address the issues. Would love to be part of the class action law suit!

    1. Wendy says:

      Same with a 2019 tucson never had an oil light on no indication of issues; started making noise towed to dealer and am being advised engine is seized.

      Is there an open class action lawsuit?

  10. Monica Mesecher says:

    We have a 2018 Sonata with an oil consumptions issue. One time the check engine light started blinking and the car wouldnโ€™t go. Hyundai said it was a safety mechanism shutting the car down due to low oil (even though the oil light never came on). Then we did the oil consumption test (it failed every time) so they did an engine cleaning and another oil consumption test (failed) but due to us being the second owner and over 60k miles they offered to pay half the price of a new engine ($8,000). We still owe on the vehicle and putting another $4k into it doesnโ€™t seem like the best move considering Iโ€™ve seen where the engine replacements have the same problem! We are in the market for a new family car and we were going to get a Palisade but not now! Iโ€™ll never buy a Hyundai again.
