After a comprehensive two-year investigation by the National Highway Traffic Safety Administration (NHTSA) into Ford’s EcoBoost engines, Ford has agreed to provide an extended warranty for affected models rather than conduct a full recall. The issue at hand, identified as a faulty intake valve, impacts over 411,000 vehicles, including popular Ford models like the Bronco, F-150, Explorer, Edge, and Lincoln models Aviator and Nautilus.
Details of the Probe and Findings
The investigation began in July 2022 following numerous reports of engine failures in Ford vehicles, primarily 2021 Bronco SUVs. NHTSA’s analysis confirmed that the intake valve in some EcoBoost engines was prone to fracturing under high temperatures, which could result in sudden power loss or engine shutdown.
NHTSA noted that the faulty valves were manufactured between May and October 2021, and subsequent changes in production processes have reduced the risk in engines manufactured after this period. Ford clarified that while some valves manufactured during 2021 were defective, the majority of failures occurred in vehicles with fewer than 20,000 miles of use.
Ford’s Recall and Extended Warranty Plan
In August 2024, Ford issued a recall for approximately 90,000 vehicles, including the Bronco, F-150, Edge, Explorer, Aviator, and Nautilus models, to offer a dealer inspection and specialized testing to identify defective valves. The F-150 had the highest recall volume, with nearly 48,000 units potentially affected.
However, Ford opted against replacing the engines, as the company estimated that most engines containing the defective valves had already failed. Instead, Ford has committed to an extended powertrain warranty covering affected models for up to 10 years or 150,000 miles, whichever comes first, offering owners greater security without necessitating a full replacement.
EcoBoost: High Performance with Efficiency
Ford’s EcoBoost engine, which combines a turbocharger with a direct fuel-injection system, is designed to maximize fuel efficiency without sacrificing power. The turbocharger captures exhaust energy to force more air into the engine, enhancing performance while conserving fuel. Despite this efficiency-focused design, the intake valve issues have prompted NHTSA’s attention and led to an extended warranty solution.
What This Means for Ford Owners
For owners of the 2021 Bronco, F-150, Explorer, Edge, Aviator, and Nautilus models, Ford’s extended warranty provides an added measure of reliability as they continue to use their vehicles. Owners concerned about their vehicles’ intake valves are encouraged to contact Ford or their local dealer for further details on inspections and warranty terms.
With this resolution, Ford aims to balance customer satisfaction and product confidence in its EcoBoost engines, affirming its commitment to addressing safety and reliability issues in affected vehicles.
