NHTSA Concludes Ford Engine Failure Investigation with Warranty Extension

Ford will extend warranties for affected vehicles after a two-year probe into EcoBoost engine failures due to defective intake valves.

The investigation covered more than 411,000 vehicles, including Ford's Bronco, F-150, Edge, Explorer, and Lincoln models with 2.7L or 3.0L EcoBoost engines.
The issue was traced to faulty intake valves that could fracture and cause the engine to lose power, primarily affecting vehicles manufactured between May and October 2021.
Ford recalled about 90,000 vehicles earlier this year for inspection and potential engine replacement if defective valves were found.
The company will provide an extended powertrain warranty for 10 years or 150,000 miles for vehicles with the affected valves.
No crashes or injuries were reported related to the engine failures, according to the National Highway Traffic Safety Administration's findings.
