The suit covers more than a dozen and a half models.
Included are both Kia and Hyundai vehicles.
Model years range from 2009 to 2022.
Complaints related to oil consumption are not unique to Hyundai and Kia. Many owners continue to deal with similar issues with their late-model vehicles from other automakers to this day. What stands out in Hyundai’s case is how widespread the oil consumption problem is and how long it has lasted.
The number of reported problems has prompted the launch of a huge class action suit against Hyundai in the State of California. The suit alleges that owners believe that they should not have to check their vehicle’s oil level as frequently as suggested by some dealerships. The latter’s frequency verification recommendations are greater than what is indicated in the owner’s manual.
Earlier oil consumption issues were common to that Theta engine family going back well over a decade. This suit however alleges that many engine types are prone to the issues. Jalopnik, based on the list of implicated vehicles, adds that Hyundai/Kia’s Nu, Gamma, Lambda, and Kappa engines are also involved.
