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. Joe says:

    My 2011 Sonata has been burning oil for years now. It is being consumed in the engine. It requires more frequent oil changes and just recently it started failing on hills and at higher speeds. I just had spark plugs replaced 2 months ago and now had to replace all coils and plugs because they were being damaged. I’m shocked to see that this is a known problem that many are suffering from that the company must be aware. Sign me up for the class action!

  6. Karen Worley says:

    The mechanic that does my oil changes recommended I look into this. I have a 2014 Hyundai Accent. It has been running low on oil for over a year now. I have to check it monthly and add. I have no leaks!

  7. Crystal Helman says:

  8. Mike Frencel says:

    I have a 2019 Tuscon that has engine damage due to oil being burned. Its under warranty. They are replacing the short block but want to charge $1500 for consumables. They failed to provide me with a rental car for over one and a half months. Has anyone had this fix done. I would imagine that anything that needs replacing due to the engine failing would be covered under warranty.

  9. Joseph stafford says:

    I have a 2018 Hyundai Santa Fe that burns oil the amount of money it’s taking to keep oil in this car is horrible. Also here engine issues

  10. Douglas Morales says:

    On July 4th 2022, I was driving on the interstate in my 2018 Hyundai Santa Fe Sport when the car would no longer accelerate, the check engine light started flashing. I proceeded to the nearest exit and pulled into a parking lot and shut off the car, I checked the engine oil and none showed even though I had an oil change with in the last 4,000 miles. I added oil 2 quarts and still showed no oil. Called a tow truck and had it towed to the closest dealer. The next morning I was called by the service advisor and was told that the engine had seized and it would be at least 2 months before they could even look at it to get approval for repair from Hyundai. They told me that they had over 30 on the lot with the same issue. Had the Santa Fe towed to another dealership who can look at it sooner but it would take a minimum of 2 weeks to get approval from Hyundai to replace the engine and probably another 4 to 5 months to fix the car. so far Hyundai has not offered and loaner car or rental, told me that after Hyundai approved the repair the may reimburse me any out of pocket expense. I have a 120,000 mile warranty and was told the the engine was covered under the power train extended life time warranty. The service rep also said that repairs were being rejected do to failure to maintain and that oil changes were required every 3,000 to 3,500 miles when the owners manual says 7,500 miles.
