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:

  • 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.

  1. Scott Shuford says:

    I have a 2019 Hyundai Tucson. The oil has been changed faithfully but the car stalled and was taken to the dealership. We were informed it needed a new engine. It has 65K on it so just out of the warranty period. Hyundai said they would pay 70% but it would still cost me $4600. It’s been there for 5 months and is still not fixed. What a waste.

  2. Garry Justice says:

    I have a 2014 Hyundai Elantra GT that was burning 4.5 quarts every two thousand miles. They kept my car for 12 months in the shop, with no explanation to this day for the oil burn. Have replaced the short block, but it’s still burning oil. Add me.

  3. Sarah Hughey says:

    I drive a 2014 Hyundai Sonata, and I have been asking repair shops for the last 6 months if they could think of any reason I have to continuously put more oil in my engine without there being any type of leak! Someone finally mentioned to me yesterday that this is a problem for some Hyundai motors so I started researching it and found this article. I don’t see 2014 in the list but anyone else experience this with their 2014 Sonata??

    1. Laura Lee Golway says:

      I own a 2014 Sonata that burns oil and has stalled and now I am unable to drive it due to some oil related problem. I am interested in a class action lawsuit.

  4. Laura says:

    Should i be worried. I just brought. A santa fe sport. . So far no problems its got 99.000 miles on it. . It seems to run great. .

    1. Ken says:

      Yes, you should be worried. My 2017 Santa Fe sport uses 3 quarts a week.

    2. Brittany Williams says:

      Be very worried!

  5. Juliann Reeves says:

    Hello my name is Julie and I have a 2016 Hyundai Accent and I do not understand why this car is not on this recall list for engine problems with oil I do regular maintenance on this car all the time for oil changes and like as soon as after I do the oil change I’m always having to put more oil inside of it and sometimes three to four quarts it just depends and also if I drive it and then I have to check it every couple of days to put more oil in it and I’m always having to put one to two quarts a day or every other day inside this car so I just wanted to know why the 2016 Hyundai Accent isn’t on there

  6. Walter Burrows says:

    I have a 2019 Hyundai Elantra. The car stalled at a red light and was towed into dealer. The dealer informed me of recall and had said it should be covered. They have denied coverage under the warranty and say the recall is for inspection only, not replacement as recall says. There is no appeal process, once they deny it, that is the final answer.

  7. Melissa Grenier says:

    I had to have the engine replaced in my 2017 Tuscon about a year ago. Luckily I bought the extended warranty at Carmax when I purchased it 3 years ago now and the engine replacement didn’t cost me anything. Now the “brand new engine” only has about 35-40,000 miles on it and it goes through a quart of oil a week. And I’m starting to notice smoke at times from my exhaust pipes when I start it to go to work in the mornings. And don’t even get me started on the transmission problems that are now starting. I would love to get rid of it but can afford to tack on the $15,000 I still owe on to another vehicle

  8. Tayler Vickery says:

    I have a 2015 Hyundai Sonata that the engine seized/locked up according to AAA service center. My car has around 125-130,000 miles on it and had no indication as high temp or engine lights on when this occurred on July 21st, 2022.. Getting towed to Hyundai dealer and have to wait 4-5 weeks to get looked at by Hyundai dealership. Been happy with my vehicle until without warning my car loses ability to accelerate or maintain speed and comes to a stop while driving. Was unable to jump car. Hyundai indicated that my car may be under warranty/recall for this issue but can not confirm until they are able to assess my vehicle in 4-5 weeks timeframe. Hoping for the best while I am out a vehicle.

  9. Deirdre Doughty says:

    I have a 2015 Hyundai Veloster that has been sitting in my driveway since November because of this oil problem (I am still praying on it) I was told my vin number was not included in the recall and there was nothing they could do. I do not have the money to replace the engine. What can I do?

  10. Nardos Adinew says:

    Hello!

    Yes, I have. 2016 Sonata and it has been consuming oil a lot, I’ve had an oil consumption test which I was told wouldn’t be covered by Hyundai anymore because it’s passed my warranty. This is ridiculous
