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. Evonne H says:

    I have a Hyundai Sonata Hybrid. My motor blew and thr whole engine was rebuilt a month after getting it back I had the muffler fall off .

  2. Juan chavez says:

    I have a 2019 hyundai tucson and uses a lot of oil about a quart a month

  3. Shirley Mack says:

    I have a 2017 Hyundai Santa Fe and in October 2021 it started burning oil, therefore, I took to Shivers Hyundai dealership and I was told to bring the car back every 1000 miles. I did that for 8 months. It consumed 3 quarts every 950-1000 miles. After all that, being without a car and inconvenience, I had to pay for an engine.

  4. EJ says:

    I have a 2016 Kia Optima. We are having the same issues. Have to keep a few quarts of oil on hand because of low oil.

  5. SLH says:

    I’m in Georgia. My 2015 Elantra GT started doing this Spring 2021. They pretended not to be aware if the oil burning issue (they were) & eventually ended up charging me over $1200 for a repair that they knew would not fix it. I had to fight tooth & nail before they finally admitted that there was a process to go through to open a warranty claim by doing an oil consumption test. In Spring of last year they notified me that my claim was accepted & then proceeded to go silent & ignore me, refusing to return calls or schedule an appointment. I’ve been putting a quart of oil in my car every 7-10 days for months. Then, last week, car stalled out in rush hour traffic & I had to be towed. I could have been in an accident or seriously injured. I got to the dealership & was advised my warranty claim was closed. I was never notified. I’m now waiting for them to inspect my vehicle but i know this company will do ANYTHING not to do right by their customers. My mom’s Hyundai is doing the same thing. This is a dangerous problem, so please be careful driving your car if it’s doing this. If I’d been on the interstate when this happened, I’d be in the hospital right now or worse.

  6. Mike Miles says:

    Same issue. 2017 Hyundai Santa Fe Sport leaking oil like crazy out of the tail pipe. No evidence on the ground at all. Only had the car about 6 months and only drove it about 3-4K miles since I had it. Engine light came on yesterday, had it checked out today and found out I had a lemon. Catalytic convert is now toast and the engine will probably need to be replaced. Stay away from Hyundai. Buyer beware.

  7. April Washington says:

    First of all, I’m so hurt, that we as consumers can purchase these POS and Hyundai can keep selling them and making money off of some who don’t have the extra money to just throw away on cars.
    My issue is with a 2017 Hyundai Santa Fe sport, tapping noise when accelerating, oil lamp flashing within 2 weeks of an oil change and 9/10 I’m going from work to home! NOT ONE SERVICE MEMBER EVWR MENTION TO ME THAT THE CAR OS CONSUMING A LOT OF OIL! That IS AWFUL!!
    Now, car is missing/ jerking like it’s about to cut off. Took to dealership only to be CHARGED $150 for diagnostic tests when the company KNOWS exactly what is going on. Still haven’t heard from the dealership, said it could be a day, 2 days or two weeks. But who cares, it’s not their problem or car. I pray all the time I’m not stuck with a vehicle that Hyundai knows has an engine problem

  8. Jodi mcclellan says:

    Same issue with my (new to me) 2017 Hyundai Tucson purchased 6 months ago. I am LIVID! Wasted several thousand dollars on this POS and will never ever ever ever buy another Hyundai in my life.

    1. Kathleen Sender says:

      I’m with u on never buying Hyundai again nor will family members or friends….pass it on. Hyundai’s problem that they should fix.

  9. Andrea Johnson says:

    2016 Hyundai Sonata. Oil change, 3 weeks later, oil light came on, my car only has 1/2 of oil.

  10. Kip Johnson says:

    2017 Hyundai Sonta Fe Sport, 114,374 miles. Engine seized. Shop said oil was leaking from everywhere but none on the ground. Engine blown
