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.

  5. Patricia M Wright says:

    My 2016 Hyundai Tucson got so bad, it stalled , chocked like it couldn’t breath, cut off at times. I had 3-4 oil consumptions and my suv still loss oil and every time i took it back to the dealership for service, the service guy would say, well we couldn’t find anything wrong wit it. I’ve been having this problem about a year into my purchase. Now my SUV has no engine and Hyundai will not own up to their problem. Hell I want my SUV engine replaced, I’m without a car because my engine is now dead!

  6. Eugenia Adamson says:

    I just came across this issue with my 2016 Tuscon. I was about 1000 miles away from needing an oil change and thought I had seen the oil light flash. I checked my oil and almost completely out. Where do I join this suit?

    1. Diana williams says:

      Hello, I have a 2016 Hyundai sonata and recently had my engine light flashing. Pulled off freeway and towed to a triple A mechanic who told me I had no oil in engine. They also said my engine was bad. I have 110k miles on my 2016 and dealership told me I needed to replace my timing cover due to oil leak. I had just had my oil changed at dealership 2.months prior. How could I go through this much oil in a short.period of time and how do I become part of this class action lawsuit?

  8. Jo Ann Paschal says:

    Where do I join. I had no idea there were others like myself. Ever since I’ve owned this 2013 Hyundai Santa Fe sport I’ve almost blew my engine.
    I constantly add oil. First thing was the light came on about two years ago. I’ve kept an eye on it ever since. Changing out a PCV valve now. In dealership on Monday. I’m second owner for about 3 1/2 years.
    I just what a good outcome, somehow.

  9. Sian Williams says:

    We are in NZ – Our 2016 Hyundai Tuscon engine blew up at 100,000 kms. No warning it was low on oil, no nothing, just went into limp mode then stopped. When we called Hyundai, the first thing they asked was – do you want us to order a second hand engine. How would they know without looking at it that it needed a full engine replacement?

  10. Braelyn says:

    I have to put a quart of oil in my 2018 Hyundai Santa Fe Sport (80,000 miles) every 300-500 miles.
