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 automakerโ€™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 hasnโ€™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 ownerโ€™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 shouldnโ€™t be, damaging the combustion and exhaust systems.

This allegedly causes โ€œabnormal wear of engine parts, oversaturation of carbon and deposits of oil sludge, ultimately requiring a costly engine rebuild or replacement.โ€

Automaker should honor warranty claims outside terms, Hyundai class action says

The plaintiffs allege that Hyundai should honor customersโ€™ warranty claims even when the warranties have expired.ย 

According to the lawsuit, Hyundai canโ€™t adequately repair the oil consumption problems and doesnโ€™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, โ€œand in most cases do not receive required engine replacements.โ€

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, 2011โ€“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.ย 

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 2017 Hyundai Sonata is doing the same thing and the dealership keeps having me bring it back every 1,000 miles to check the oil then they add a quart of oil tell โ€˜me to come back in another 1,000 miles. It had 56,000 miles on it when this started

  2. Matthew Criscione says:

  3. Frederick Pajak says:

    2017 KIA Forte. One quart of synthetic oil added every 8 โ€“ 10 days! How do I join this lawsuit?

  4. Carmela Grimm says:

    2014 Hyundai Sonata uses 3 quarts of oil every 5000 miles

  5. Andrew Petersen says:

    Finally! When it was under warranty they refused to anything even after I did a consumption test. Why? According to their spec sheet it is within allowable limit to burn up to 1QT per 1,000 miles. It holds ~5Qt oil, at a change interval of 7,500 miles even according to their spec it would operate for 2,500 miles without any oil left. REDICULOUS!!! So I religiously put .5QT in my engine every 500miles.

    Where and how do I add myself to this?

  6. Emmy Barnett says:
