Update:

  • 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 Hyundai Sonata that I bought not even 2 months ago from a private dealership with 71k miles in the car. And just today I brought my car to the Hyundai dealership because of an oil consumption problem. Every week I have to put in a little less than 2 quarts of oil in my car!!! That is not normal. I thought I was the only one with this problem. Now that I am noticing how many people are dealing with this, something has to be done!!

    I have a 2017 Hyundai Sonata that’s over 140,000 and I’m constantly putting oil in plus I’m constantly have to go get oil changes also. I have replaced the PCV cover also and it still didn’t fix the problem and my car also is idling high. I’m very interested in this case.

    My 2017 Hyundai Santa Fe has 95,000 miles. I have an extended warranty but they should not be held liable for this situation and I should not have to pay my deductible.

    The past couple of oil changes I have been informed that the oil is low. My oil changes has always been on time. My car has been having a hesitation and rough idle and the oil light will blink on then off. My last oil change was on 1/26/23 by Midas that informed me of the issue. I had finally had enough and scheduled an appointment with North Hyundai on 3/29.

    I spoke to Hunter in service, that informed me that the oil was low again and they top it off. He said I would have to pay 299 for a oil consumption test to be performed. He also could not understand how I was so low after just had an oil change 2 months ago. I spoke to my husband and wanted to know more about this test. After searching the internet, I see that this is an issue that is going on with Hyundai and a class action lawsuit is pending. So why am I paying to get this done. I have owned 9 Hyundai Santa Fe’s, 1 Tucson, and 1 Accent. I have been that loyal customer ever since a Santa Fe saved my husband’s life. And this is what I have to deal with.

    Hyundai asked what do I want to resolve the issue. I want you all to do this test free of charge. If it shows a problem like I keep being told, for you to replace the engine. Rights now, I’m having to keep checking the levels so nothing is damaged. I should not have to do that. I also want you all to give me a loner vehicle while my car is being in service free of charge. I don’t think that it’s too much to ask for a loyal customer. Hyundai replied there is nothing they can do. I will not buy another Hyundai. This is a slap in the face.
