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.

    Same issue with my 2019 kona. Would.love to be included.

  2. Don says:

    I own a 2016 Hyundai Tucson with every one of these issues. Hyundai will not approve an oil consumption test but offered to cover 80% of the cost of a new catalytic converter replacement. Cost…..$4500. They will cover $3600. All that sounds like to me is that they acknowledge there is a problem. And $4500! For that work. Seems off.

  3. Cheryl Lynne Dickinson says:

    I am burning thru oil every 500-1000 miles. I have paid so much for engine issues only told car needed a system update. Did that and still running hot. I have a 2016 Sonata

    1. Marcin Witruszynski says:

      I have a 2016 SentaFe – 68k miles and the engine failed with engine slap. 2 months at the dealership they have literally never called my to give me an updated, the only info I get is when I call or stop by. Last week I was told that the car is no longer under warranty and costs to repair will be out of pocket. 1 week later, I can’t get the dealer to provide a quote or time estimate for the repairs. I’m beyond words furious and disappointed with the complete lack of accountability. I really think the class action missed the breadth of the issues as I’m having the same problems with my 2016 Senta Fe SE.

  4. Fausto says:

    I have a 2018 Sonata and I have to add 2-3 quarts of oil every 1000 miles. So I do a little bit of two oil services in a range of 3700 miles. I have taken it in to the dealer for the knock sensor issue but they just erase the code and say ( oh we need the CEL on with the code so we could do more trouble shooting.) I’m sure my car has bad piston rings and that’s why it throws the knock sensor code. I’m just waiting for my engine to lock up at this time.

    I need to be part of this lawsuit and looking for an attorney.

  6. Lawrence S McDougle says:

    I have a 2016 Kia Optima that has gone through the oil consumption tests and had the engine pistons cleaned for carbon build up and there is still an oil consumption issue. My dealer is asking Kia for a replacement engine as a good will gesture. No word yet on what Kia will do. Please add me to the class action.

  7. Angie Payne says:

    I have a 2018 Hyundai Sonata limited and I’m having the same issue with my car using excessive oil. I have been taking my car back and forth to the dealership in Kennesaw, Ga every 1000 miles for them to add a quart to 2 quarts until the next 1000 miles. I have gone thru the oil consumption test and they still haven’t done anything about it. Please add me to this lawsuit. Thank you!

  8. Mark Hill says:

    2016 Hyundai Sonata SE – significant loss of oil (no leaks) over the last year. I will be going to the local Hyundai dealer soon to start the process of them telling me they won’t do anything and will document everything for a lawsuit.

  9. Darlene Butler says:

    I have a 2017 Hyundai Tucson and I am going thru the same issue. Just a few days ago, checked the oil because. of engine clatter, no oil registered on the oil stick. Did an oil change and the noise didn’t go away, it’s actually worse, several people that know vehicles said spun bearing and oil consumption
    After reading about the issues Hyundai I am very upset about this Major repair
    My car has been well maintained and I have 114,000 highway miles and it’s in perfect condition but what good is that now.
