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. Bradley Stapleton says:

    I have a 2013 Hyundai Azera that seems to burn oil much faster than normal. More than 3,000 miles will see a significant drop in oil level. On two different oil changes, and I normally do these at 5,000 miles, I’ve not had any oil on the dipstick. The manual recommends 7,500 mile oil changes, so if I followed that recommendation the engine would’ve certainly seized up by now.

  2. Lauren Berry says:

    I have a similar problem with my 2016 Elantra Hyundai. I have to put 4 quarts of oil in it a week. This is very expensive, but I need to do it or the engine will blow. All this oil eventually clogs my catalytic convertor a year later and I replace it each time. I know it’s time to replace it when my car can only go 5 miles per hour up slight hills and only 30 miles per hour is the fastest it can go. This only takes a year for the catalytic convertor too fail, I have already replaced it twice now. Each time it cost me thousand’s of dollars. I can not afford this car.

  3. Kim Green says:

    I have a 2016 Hyundai Tucson. It burned oil excessively. I checked the oil before a road trip and about 3 hours later all of the oil had burned out and this caused my engine to fail on the highway 3 hours away from home. This happened in November 2021 and I am still making payments on it.

    I’m having the same issue. Taking it today to see if I’ve lost a quart after combustion cleaning. Which they charged me $832 for, and they also threw some bad spark plugs in and wanted to charge me $270 to replace. I had iridium plugs and new ignition coils put in less than 20000 miles before this. When I started looking at my engine at dealership, while on the phone with Hyundai Corp, they ran out and said they would change for free. My car was in total different state than when I had dropped it off the day before. After they changed spark plugs can definitely feel more misfires. Guessing this is never gonna be resolved.

    1. Matthew Bellamy says:

      And also been through one catalytic converter because of this issue. The one now is clogged within 25000 miles and exhaust is so strong you can smell while driving.
