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 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.

    I have a 2017 Santa Fe Sport that recently developed a leak after excessive consumption.

    I’m taking it to my mechanic this weekend. This is disappointing as I specifically purchased this vehicle afte4 dealing with excessive oil consumption with 2 Saturns I previously owned. My mechanic advised me to get either a Toyota, Honda or Hyundai. I should have gone with Toyota.

  2. Jessica Bartleson says:

    I am also affected by this. I have a 2017 Hyundai Sonata. Per my mechanic I should be checking my oil every week. I still owe money on this vehicle and am worried it is going to seize and won’t be covered under the warranty!!

  3. Charlotte R Glass says:

    My 2016 Santa Fe Hyundai has apparently been burning oil for quite sometime. Just finding out about the issue. But now I have to keep oil on hand to add to it about every 1,000 miles in between oil changes. It also hesitates on take off. Just wondering if anything is going to be done about it. Can’t afford to trade cars.

  4. Ronnie Patton says:

    I have a Kia Sorento/2019 and I see there was a class action law sit against Hyundai’s & Kia’s concerning problems with their 2.4 L GDI engines for excessive oil consumption but I was told my vehicle wouldn’t apply on account of the vin number but I bought it new in 2019 how does it not qualify?

  5. Monte Lynn says:

    2015 Hyundai Santa Fe engine threw a cylinder rod through the engine block. Under 100,000 miles. Took it to the dealership for diagnosis and they told me it was a mystery and there was nothing else wrong with the vehicle. Because I’m not the original owner warranty was void. Now I’m stuck paying on a vehicle that I can’t drive.

    1. Monte Lynn says:

      Edit: this is a Santa Fe limited, 3.3 L V6

  6. Cheryl Lovett says:

    My 2016 Hyundai Sonata has been burning oil since 50K miles. At 55K and 60K miles, no oil when checked. Car became unsafe and undrivable at 65K, brought to my mechanic who said there was no oil and some substance like metal shavings in the residue, along w/Cylinder 4 misfire. Had to tow to dearlership who kept the car for 3 weeks; they confirmed the misfire, no root cause for the leak but insisted it wasn’t engine related and I’d be responsible for all costs. Including over $2300 I spent on the rental alone while they had the car tied up. Despite evidence of there being no oil at past few checks, they would only do a “seal test”. One year later, in exact same boat, no oil at every check.

  7. Maria Moore says:

    I have a 2017 Sonata. I have to check the oil every 5 days. If I forget it’s typically almost dry. This same car was stolen today which is another glitch in this model. I would like them to acknowledge and compensate. They will do neither. Each time I taken it to the shop they get me for a couple of hundred. It’s sickening.

  8. Tracey Kirksey says:

    Please add me 2016 Sonata

    1. LeAnn says:

      Same here!

  9. Tracey Kirksey says:

    I own a 2016 Sonata. I have had to check my oil every few days with needing to add oil about every week to 10 days. I am currently facing replacing the SECOND gasket and plugs because so much oil has damaged them. This morning the car acted as if it had to muc caffeine and was shaking, engine light came on and lost a fair amount of power. Diagnosis was the gasket and plugs which I just had done in March.

  10. Jennifer B. says:

    I have a 2017 hyundai Santa with 60,000 miles and I’ve only had it 1 year and now the oil light is coming on. I have oil changes regular and it started leaking this week. My engine burning oil really fast and at this rate I’ll need a new engine by Christmas. Please advise how I join this lawsuit. I would like for someone to contact me.

    Thanks
