Ford Coyote Engine Lawsuit: The 5.0 V8 Oil Consumption Claims

The Alleged Defect

The 5.0-liter “Coyote” V8 is one of Ford’s signature engines, used in the Mustang GT and F-150. A class-action lawsuit alleges that a generation of these engines — in roughly 2018–2020 model-year vehicles — consumes oil at an abnormally high rate, with some owners reporting the engine burning more than a quart every few thousand miles despite no visible leaks. The suit points to the engine’s oil-control system, alleging the piston rings do not seal properly, letting oil slip into the combustion chamber where it is burned off rather than lubricating the engine. Running low on oil can accelerate wear or damage an engine.

The complaint also alleges Ford knew about the problem but communicated it mainly through internal technical service bulletins to dealers rather than clearly warning owners.

The Litigation Status

The lawsuit was filed in federal court in Michigan in 2025 and is at an early stage — no class has been certified, and there is no settlement or finding of liability. As with other oil-consumption cases, key questions will be whether the alleged defect is proven, which exact engines and model years are covered, and what Ford knew and when. Owners considering the litigation should watch the case’s progress rather than assume any particular outcome.

This is a newer matter than the settled oil-consumption cases involving other automakers, so it has further to run.

What Owners Should Know

If you own an affected Ford, check your oil level regularly between changes — abnormal consumption is easy to miss until the level is dangerously low — and keep records of oil added, any consumption tests and dealer visits. Ask your dealer whether any technical service bulletin applies to your engine. Documentation is what supports both a warranty claim and any future class relief.
