Over the last several years, many Hyundai and Kia owners in the U.S. have raised serious concerns about engine safety, engine failure, fire risks, and costly repairs. These complaints eventually led to multiple lawsuits and recalls involving specific Hyundai and Kia models equipped with certain Theta II, Gamma, Lambda, and Nu engines. If you’re searching for “Hyundai class action lawsuit engine,” “lawsuit settlement,” “who can claim,” or the latest case update, this guide explains everything in clear, simple language.
Whether you already received a notice or are just trying to understand if you qualify, here’s a complete breakdown of how the lawsuits work, what payouts or repairs may be available, and what to watch for in the coming months.
Why Is There a Hyundai Engine Lawsuit?
Millions of Hyundai and Kia vehicles from the early 2010s through the early 2020s reported issues related to:
- Engine knocking
- Sudden stalling while driving
- Excessive oil consumption
- Engine seizure
- Vehicle fires
Many of these problems involve the Theta II GDI engines, which were alleged to have manufacturing defects that could restrict oil flow and cause premature engine failure.
Because the issue affected so many drivers, attorneys filed class action lawsuits claiming that Hyundai:
- Knew about potential safety issues
- Did not warn consumers
- Delayed repairs or denied warranty coverage
- Failed to recall all affected vehicles in time
Although Hyundai has issued major recalls and extended warranties, new cases and updates continue to emerge, keeping the Hyundai engine lawsuit in the news.
