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.

  1. Marcus Raymond says:

    2016 Hyundai Santa Fe Sport with the 2.4L N/A engine. Consumes oil badly. How do I get involved in the lawsuit?

  2. Rhonda says:

    I am in PA and I have a 2017 Hyundai Tucson. During the summer months, per the oil consumption test performed by a Hyundai dealership, I am using a little over 1 quart of oil every 1000 miles. I expect this will increase greatly once winter comes and I start my car in the morning before work. I was told I can have a combustion cleaning performed for a little over $500 but that it likely wouldn’t do anything because this is “normal” usage.

  3. Charles Mason says:

    My 2018 sonata sport has been having issues with using excessive oil, especially recently. Mechanic shop found no leaks time and time again. I’d like in on this suit

  4. Kui Lin says:

    2015 hyundai sonata 2.0t sport, burning 1.2qt every thousand miles at 92k miles, going to do oil consumption test with dealer, will update how it goes.

  5. Sarah Horton says:

    2017 Santa Fe. I want to join

  6. Scott says:

    My model year (2009) Hyundai Sonata is not listed but it too suffers from the same issues. I have owned it since November of 2009 and has been a problem since I bought it. I am I also able to join in?

  7. Mike Daubert says:

    My 2018 Santa Fe 2.0T, has 47k miles and uses about quart every 2,500 miles. It never used oil until this last service from the Hyundai dealer. It goes into dealer this week to for service and the oil consumption. I was already told by the dealership that a quart every 1,000 miles is acceptable to Hyundai.

  8. Melissa Grenier says:

    I bought my 2017 Tucson SE in 2020 with 38,000 miles on it. Had my oil changed regularly, accused the dealer of not putting enough oil in my car, no warning lights. At 70,000 miles the engine blew up on me due to the 3rd piston ring shattering into pieces from no/low oil. I had the CarMax warranty that replaced it while I had to drive my husbands car for a MONTH while they replaced the engine. Now 30,000 later I’m still having to add 1-1/2 quarts of oil every week. I only drive around 400 miles a week

  9. Milene Garcia Maldonado says:

    I have a Tucson 2015 with the same problem ,I have to add 3 quartes of oil every 2000 miles . How can I joint the law sue to get en engine replace or else ?

  10. keona whrighter says:
