Theta II Engine Lawsuit Says the GDI Engines Have Oil Flow Problems

The Theta II Gasoline Direct Injection (GD) engine is earning a reputation for stalling and eventually seizing, leading to a class-action lawsuit.

The Kia Theta engine lawsuit targets the Theta 2-liter and 2.4-liter gasoline direct injection engines, also known as GDI engines. According to the plaintiffs, the engines contain defects that cause a restriction of oil flow through the connecting rod bearings and other parts of the engines.

Hyundai is facing a similar lawsuit that is currently awaiting final class-action approval.
