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.

    My 2015 sonata sport is have this problem. My mechanic said all I can do is wait for it to blow up. If that’s not the scariest thing I’ve ever heard I don’t know what is. I get a professional oil change every three months and every 2 to 3 weeks have to put more oil in the engine. I love my car it drives perfectly but this problem has filled me with so much paranoia I literally drive with my radio off and beg my children to not make a sound just so I can listen to the engine. I would love nothing more but to be part of this lawsuit in hopes to have my engine replaced.

  2. Brittany Williams says:

    I had a 2017 Hyundai Santa Fe sport was having to add oil almost every 2 weeks when my engine finally blew. Took it to a dealer ship was told that it was oil related and that they wouldn’t replace it for free unless a rod was thrown. It was going to cost me $10,000 to MAYBE fix my car. I ended up having to file bankruptcy losing all of my credit and I’m still bumming rides!

  3. Machell Lopez says:

    I am going through this now with my 2017 Sante Fe Sport. I have to add 1 quart of oil approximately every 1,000 miles! It is so frustrating! I have to keep a log of when I add oil and the mileage because on top of that the oil light doesn’t come on until it is almost empty. Hyundai should really help with this. How do we all get a nationwide class action suit started!?

  4. Debra Vaquera says:

    i have a Hyundai Sonata 2017 Spirt model since December of 2021 i’ve been dealing with excessive oil use in this car. they had me bring it in and they did a check but it wasn’t until june 27, 2022 that they finally did the last check and told me they needed to replace the engine. But they want me to cover 25% of the cost. every single maintenance and every single oil change has been done by the same Dealership and when they tell me to. So why am I covering any part when the car started this problem at 65,000 miles? I’m wondering if the 25% is a Hyundai number or the Dealership just trying to get money from me when Hyundai is covering the repair a problem common to this car, model and car year?

  5. Steve H says:

    2018 Tucson SEL. I’ve read so much about this and am genuinely concerned. What’s the advised course of action in case this does affect me?

  6. Brittney says:

    I own a 2015 sonata limited. I have had oil burning off for the last 20000 miles. It only has 85k. Some oil changes have been up to 4 qrts low. Took it into the Hyundai dealership where I was told they would not even do a consumption test because I am the second owner and it’s not covered for a second owner after 60k miles. Then they said “but if the engine blows before 100k it’s covered by power train”. I love my car but this is ridiculous Hyundai!!

  7. Kayla says:

    Yes my 2015 Hyundai sontata takes oil like crazy and now it’s leaking oil also

    1. Jamesha says:

      My 2016 Hyundai sonata eats oil. I just had to replace engine parts because of the consumption of oil so fast.

  8. Ken says:

    Yes, you should be worried. My 2017 Santa Fe sport uses 3 quarts a week.

  9. Nicole Serna says:

    I’m currently one these people! My vehicle was purchased in 2018 Sonata new,cared for properly and it’s now burning oil like crazy and the engine light is on now.

  10. Surujdeo rampersad says:

    Changed my oil on my 2019 sonata and 3000 miles down the road my oil lights came on checked my oil and there was no oil on the dipstick i added 2 and a half quarts so i will be keeping an eye on this issue
