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. Mario Rios says:

    My 2015 Santa Fe Sport went out of oil without any warning. Check engine light blinked and P1326 code was diagnosed.
    Did the oil and oil filter service in the dealer all the time. Car is in safety mode now (60 miles PH max). What can i do? How can i be part of the lawsuit?

  2. Terri Tompkins says:

    My 2018 Elantra stalls while driving and is requiring multiple quarts of oil between oil changes. When the car stalls there’s no warning. It’s dangerous!

  3. Scott says:

    Hyundai translates to POS sorry ass engine. Boycott Hyundai and Kia. Do not buy these poorly engineered, non- reliable, disposable cars. I think that I’d rather have a 74 Pinto than drive another Hyundai or Kia.

  4. Scott says:

    My 2016 Sonata 90k ingests 1 quart of oil per 700 miles. Already oil fouled/ carbonized the #2 plug. Dealer just did the useless oil consumption test to waste my time, now they want to do the useless and expensive intake port flush. I’ve been turning wrenches for a long time, their not bullshiting me. Hyundai needs to warranty out these turd engines. Extreme amount of blow by, ring problem.

  5. Bill Pozzi says:

    My 2017 uses lots of oil.

  6. Cheyenne W. says:

    2017 hyundai sonata with oil consumption to the point of adding up to 5 qts between oil changes every 3,000 miles! Check oil light NEVER comes on even though dipstick will show its low! Car has a little over 100,000 miles on it, and just this week after an oil change last week, it failed to start and the check engine light has come on. Sitting at mechanics lot now.

  7. Cindy Stroud says:

    Have been trying to get an appointment with Hyundai dealership for over a year but they will not furnish a vehicle while they keep mine indefinitely! I have spent hundreds of dollars on oil and mechanics just trying to keep this Santa Fe running long enough to get back and forth to work I can’t even drive it out of my area due to the chance of it breaking down on me! I’ve NEVER dealt with anything this frustrating and expensive! It is a nightmare!

  8. Shelly Cory says:

    2022 Tucson with 7K miles on it. Car stalled in drive mode. Knocking in engine. No warnings given. Dip stick showed no oil so added 2-3 quarts. Towed to dealer in Austin TX. It is Been a week when told today needs new engine. What are my rights to get my money back?

  9. Dulcia Riddle (Previously Benitez) says:

    I have a 2017 Hyundai Sonata Sport and I had to replace the engine for $6,000 and that’s not including the finance charges for the auto maintenance loan. The car was somehow using up way too much oil, not burning or leaking…everything was junked up even with full synthetic regular oil changes. Also, the newer engine had 30k miles on it and already all junked up per the new mechanic. The newer engine was only in the car for a few months! I would also like to be part of this lawsuit if possible.

    1. Donna Perras says:

      I had a 2017 Hyundai Santa Fe Sport, Did regular oil changes with what it recommended, and the guys at Valvoline would say Wow when is the last time you put oil in this! I always went on time and the same question always came up! I would LOVW to be part of this lawsuit!

  10. Steve Mongelluzzo says:

    I have a 2018 Sonata and I put 3 qts of oil every 1000 miles…I am at present doing an oil consumption testing protocol which is useless. I have had a knock and ping in that car since I bought it…I will never buy a Hyundai or Kia vehicle ever again !! JUNK !!!!
