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.

    I have a 2012 Kia Optima e gdi and have to put a quart of oil in every 500 miles or less. Was told by the dealership they can’t or won’t do anything for the engine until I get a check engine light to come on, which probably won’t happen unless I let it go low on oil. I don’t believe this is right. I like the car but the engine hasn’t acted right for about 4 months now.

  2. Glenn Martin says:

    I have 2016 Hyundai eluntra with 154000 miles and used a quart every 700 miles ,is this excessive

  3. Chantal Fremit says:

    Our 2016 Hyundai Sonata burns a quart of oil every 3000 km, it is ridiculous to have a modern car with such a terrible flaw.

    1. Travis Hayes says:

      I just started driving my wife’s 2016 elantra to and from work. It’s better on gas. My drive to work is 58 miles each way, 3 days a week. I changed the oil, 2 weeks later checked it and had to add 2 quarts! 2 weeks later it died while going down the highway and no oil on the dipstick. This car has been the worst vehicle ever. Still owe 3k and now can’t even drive it.

  4. Beth Maloney says:

    I have a 2015 Hyundai TUCSON and am experiencing oil problems. The check engine light keeps coming on because the oil is low and have to keep adding oil. I only have 80,000.00 miles.

    Soooo frustrating. No more Hyundai’s for me or my friends and family.

  5. Emily D says:

    I have a Hyundai Tucson 2019 and the oil consumption has been a nightmare. I have to continually put oil in it or else it’ll make noises especially when accelerating and the car stalls. Getting up any slight hill is a nightmare with everyone honking at me but the car won’t accelerate past 40mph up the hill if I’m lucky. I’m from the Bay Area so hills are inevitable .

  6. Paige Elliott says:

    I would like to join lawsuit. Was just told today losing one quart every 987 miles but was told original 100k warranty did not transfer to me as 2nd owner and therefore not covered I am in Alabama.
