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.

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.

    2017 Hyundai Elantra Limited. I’ve done oil changes every 3k, fuel system cleaning, radiator flushing, transmission flush, etc. I have about 122k miles on the vehicle and am worried it’ll die at any moment. It’s nerve wrecking to wake up every day and wonder if today is the day I’ll need to buy a new vehicle at the current overzealous prices and interest rates. Since the oil consumption issues go back to at least 2012, they knew when I bought the thing there was a high chance of issues. Had they told me I’d have oil issues and potential engine failure in a few years after purchase, I would have purchased a different brand. Hyundai might not make things right, but they definitely won’t get any more money from me or my family. I’d rather buy a brand that’s well-known and capable of lasting 200,000+ miles with minimal issues.

      The check engine light has only come on once since I’ve owned the vehicle. Around 52,000 miles it became extremely sluggish and was found to have coil pack issues. Hyundai apparently issued a recall for a different model year, but not the 2017 that had the same engine. I did end up getting the coils replaced at no cost because I was under 100,000k miles, but they weren’t willing to do it under the recall.

    2016 Kia Sorento, no oil light, no check engine light of any kind. Come to find out I have no oil and engine is shot $11,300 later and I can’t get any reimbursement because I am the second owner, but was under the 100,000 miles had I been first owner. However, when I bought the vehicle I was told it had 100,000 mile warranty. This is the 6 cylinder, so not covered under the recall, but many many people have had the same problem with the 6 cylinder. How do I start a class action??

    I’ve only had my kia optima for 10 months before i started to see problem with my engine. I then took it to a mechanic I know, and he told me that my engine was consuming oil and i should try to get in contact with my warranty. After calling them they had sent me to 2 different place to confirm, and when i got to kia i was then told they couldn’t help cause i didn’t have all of my service records from taking care of the car. I typed this to tell anyone to read all documents before you sign them and to keep all service records on your car. The warranty company are always trying to find ways to flake out on there end of the deal

    I drive a 2011 Santa Fe the engine light stays on regardless of maintenance. It always says intake manifold .. how many times do you need to replace it? It’s not cheap.. I’ve replaced a few parts but, with the cost now days who can afford it. This is irritating when it’s your only vehicle..

  5. Jason Waltenberry says:

    2020 Hyundai Tucson started “burning oil” about 6 months ago. I was told by the oil change place to continue to put oil in between changes. No check engine lights come on except once in a while the oil light. I still have 16,000$ to pay on my loan. I bought it brand new. I am over the 100,000 warranty. I was driving on the highway and the engine just stopped. Took it in and they said the piston blew the spark plug. And no oil was in the car. The dealership won’t help me.

  6. Barbara A Skeen says:

    I have a 2019 Hyundai Accent that we are putting oil in constantly. Dealerships know it is a problem and tell me that it is normal to need a quart every 1,000 miles. I have asked for them to test / replace and they told me there is nothing wrong with it. Would like to get some additional help.

  7. Cora Fedornock says:

    I’m having oil consumption issues with my 2017 sonata. I would like to speak to somebody regarding this issue.

    2018 Hyundai Tucson. Excessive oil burning yet regular oil changes at the 2-3k mark. Also on my 3rd catalytic converter and it’s been to the shop more times then I can count. Dealership is no help, Hyundai is no help. It’s ridiculous

  9. Robin Roberts says:

    I have a 2017 Hyundai Tucson its been in shop three times for useing to much oil I bought it got it home after a week checked oil and it didnt even show on stick and now they are doing test on it and another thing when you push on gas sometimes it wont move and then it takes off but I about got killed in it getting on highway.I have nothing but trouble since day one and something is got to be done I payed to much for car for it to be doing all this stuff

    2017 Santa Fe Sport with the cursed 2.4 gdi engine. Purchased used because the wife loved the vehicle. Used a lot of oil, 3-4qts between oil changes. Not quite a year later now and the thing developed a cylinder 4 misfire while wedding dress shopping for oldest daughter. No compression and no warranty! Dealership finds “burnt valve” to be the problem. My issue is what was the cause for the valve to “burn.” Probably excessive carbon deposits from the oil consumption. 103k miles on the car and now an additional $7,000 for another suspect 2.4gdi. Oh one more thing, dealership had no loaner vehicles b/c of too many other engine repairs scheduled 🙄.
