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:

  • Who: A group of Hyundai and Kia vehicle owners are suing Hyundai Motor Co.

  • 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 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.

    2013 Hyundai Sonata
    Less than 80,000 miles burning close to 4qts of oil at recommended oil change interval. Want Hyundai to fix this as low miles for a 2013 and all oil change records kept since purchased.

  2. Rachel says:

    My 2017 Hyiundai Tucson started exhibiting oil consumption in February 2022 and I was putting 2 quarts in it about every 1000 miles, if that. I had it into the dealer because I thought there was a leak and they said there wasn’t and sent me on my way. In February 2023 the care stalled out and the engine failed and the dealer and Hyundai denied my claims for warranty repair even though I received a notice for extended warranty for engine repair due to this reason and instead placed blame on me for “lack of maintenance” even with additional receipts supplied.

  3. audrey myers says:

    2018 sonata sport. I’ve got 153000 miles on it. I use approximately 3 oil changes between oil changes, that’s how much oil I go through. I do all maintenance and miles are mostly highway. I’m told I’m at the end of my motors life. I always thought doing maintenance on vehicles last. Hyandai told me they will not help at all self pay. I’ve never seen a car that someone took car of have this issue. I’ve got plenty of power just oil issue.

  4. Bobbie Ferguson says:

    I have a 2017 Santa Fe and it broke down on the side of the road last week at 9:30 at night when my 16 year old daughter was driving home from church. She called me scared and crying. Check engine light was on, car was shaking and would not go above 40 mph. Knock sensor needs replacing and camshaft code came on. Oil was just changed less than 300 miles and it was bone dry… absolutely insane!!!

    1. Brianna Kin. says:

      I got my 2014 Tucson in June of 2020, and by December of 2020 my engine was blown. I used my extended service warranty that I purchased with the vehicle, to replace the engine after blowing a rod bearing while driving 70 on the highway. Got it back in February/March of 2021, and despite Hyundai having my car in the shop more than in my own possession with no rental offered, my engine blew once again in January of 2023. This most recent time it blew going 75mph on a 3 lane highway, in the dark, and the entire vehicle locked up. No power steering, no ABS, could hardly even push the E break to come to a complete stop in a random driveway before nosediving into the ditch. Hyundai fights me tooth and nail to cover ANY thing on the vehicle. I’ve had numerous cases open with them, and will continue to do so until this is made right. I still owe $5,900 on my car, but HMA would rather sweep safety under the rug, and pay over $9,000 per engine replacement. All I’ve ever asked for is a safe, reliable vehicle or to be bought out of my loan and I’d gladly return the vehicle. Between the car payment & insurance that I’m required to have on it even tho I’m too scared to drive it? I pay $500 a month for a car that just sits. With the thefts, seatbelt recalls, spontaneous combustion, and multiple engine failures? I feel it is my right as an American citizen to at the very least get what I’m paying for! All we’re asking is for HMA to do the right thing and take our safety into consideration. I’m not asking for a handout, I’ve paid almost $10,000 on this car in a little over 2 years; and I’d gladly give it back to Hyundai. If they paid off my less than $6,000 auto loan, they could have the vehicle back & I could move on with my life without fearing every single day that my vehicle will kill me & my family.

        I bought a 2019 Hyundai Kona through Enterprise Car Sales but when I started having some engine problems and subsequently received the recall notice I brought it to the AutoNation Hyundai dealer in Tempe Arizona where I live when my miles were <90k.. they took it and sat on it for a couple of weeks and told me to come pick it up but not only did they do nothing to it my battery was dead and the car was dirtier than when I left it. They charged me for an oil change but replace the battery for free. The second time I brought the car back I pushed the issue of the recall and then we did the protocol of three oil changes and then they came back and told me it didn't qualify now because my miles is now over the limit. It was not when I initially brought it in and they were less than courteous about it. I am now trying to get Enterprise to one of the aftermarket warranty I purchased. I also contacted Hyundai national office directly and they told me they also had record of the claim but had denied my vehicle claim citing evidence that the engine did not have sufficient oil although they had done the oil changes there at the Tempe AutoNation Hyundai dealer. Would appear the engine ring issue and the vehicles oil consumption ( which is the issue reason for the recall) it's causing issues to my engine. I am completely frustrated by this whole process and will never trust this kind of vehicle again

  5. Robert Spence says:

    I have a 2018 Tucson with 45,000 miles and the oil level was bone dry 600 miles before my next scheduled service!

  6. Joseph Wahinehookae says:

    I have a 2017 Hyundai Tucson Nu engine and at 60,000 miles it started consuming a ton of oil. Probably a quart every 200 miles or so. Should’ve brought a Toyota.

  7. Kristy Stamps says:

    I bought a used 2016 Santa fe sport kept oil changed regularly and 1 day the engine light blinked once and then it started knocking while driving down the road. Come to find out there had been a recall that we were never sent a notice on for the warning lights to let you know that oil was low. There were no signs of oil leaking and oil light never came on and now with no warnings that my car was burning oil i have a car that I owe $9000 and am still paying for and it’s useless, I sent a complaint to Hyundai and it was not under warranty since bought used and noone seemed to care.

  8. Louis sacco says:

    2019 sonata. Same issue. Hi oil consumption. Dealer lied and said they fixed it by cleaning engine.
    I want in on the class action suit.

  9. jenny maldonado says:

    I have been having the same issue with my 2016 Hyundai Sonata I have had my car for 3 years now for the past year I have been going thru hell with the engine with oil consumption, spark plugs, engine light, and a knocker sensor, and car shaking and turning off. Hyundai dealership put my car thru so many tests which it has failed and still like that I can’t get any help I just call my warranty please I also can’t get any help with them either, I just spend $1,300 on getting my car fixed and on a rental, cus Hyundai refuses to give me a loner.. my biggest scare was before this happens I was on my way to work with my toddler in the car and it shut off in the middle of the high way where we also got hit by a semi-truck with it wasn’t for an off duty cop and other people that stop to help. I don’t know what would have been of my and my daughter.

  10. Craig Rheaume says:

    2013 hyundai veloster turbo.. needed new engine and turbo at 130 000km. Vehicle burnt off all of its oil before next scheduled oil change. I do mine every 5000km. Result..full catastrophic engine and turbo failure.. hole in the block. 3 Pistons obliterated.. turbo innards damaged. Cost to replace engine and turbo after labor.. $10k out of pocket. Thanks hyundai.. all VT’s should have engine recalls!! I know of many who have suffered the same situation from forum discussions. And funny enough just blew a head gasket on the used 90k replacement engine!! Unacceptable..I want compensation!!
