Ford faces a lawsuit over alleged defects in its 2.3-liter EcoBoost engine. Trevor and Sarah Nelson filed the case in the U.S. District Court for the Eastern District of California.

The Nelsons' troubles started in December 2023 when their 2018 Ford Mustang showed signs of trouble in Costa Mesa, California. The car's engine light turned orange, and it shook when started. A mechanic found coolant leaking into the engine. The repair bill came to $9,460 for a new engine, $460 more than the initial quote.

This incident led to the lawsuit, which claims Ford knew about these problems since June 2012. The suit alleges that the 2.3-liter EcoBoost engine has several issues: Coolant leaks into engine cylinders, causing power loss, cylinder wall corrosion, oil dilution and contamination, engine failure, and overheating. These problems could lead to catastrophic engine failures and even fires.

The Nelsons say Ford hasn't properly fixed the problem. They claim the company only offers quick fixes like changing engine software or adding coolant sensors. The lawsuit wants Ford to replace faulty engine blocks.

This isn't the first time Ford's EcoBoost engines have come under fire. In 2012, Ford recalled cars with the 1.6-liter EcoBoost engine due to overheating and fluid leaks. However, Ford hasn't issued a recall for the 2.3-liter version.

The lawsuit affects more than just Mustang owners. Several Ford and Lincoln models use the 2.3-liter EcoBoost engine.

The Nelsons want a jury trial. They're asking for various damages, including compensatory and exemplary damages. They also want the court to order Ford to fix the problem.

Ford hasn't commented on the lawsuit yet. As the case moves forward, it could impact many Ford and Lincoln owners across the country.
