A two-year investigation by the National Highway Traffic Safety Administration (NHTSA) into faulty intake valves in Ford’s EcoBoost engines has finally come to a close. The investigation, which began in July 2022, covered over 411,000 vehicles equipped with the popular engine, spanning models like the Ford Bronco, F-150, Edge, and Explorer, along with the Lincoln Aviator and Nautilus.
The root of the problem lay in defective intake valves that were prone to fracturing when exposed to high temperatures during regular engine operation. This could lead to a loss of power or even a complete engine shutdown. The NHTSA’s investigation revealed that the faulty valves were manufactured between May and October 2021, and subsequent changes to the manufacturing process have eliminated most of the at-risk engines.
Ford, in response to the investigation, recalled 90,000 vehicles in August 2023, offering a dealer inspection and a test to identify vehicles with potentially faulty valves. The F-150 was the most affected model, with nearly 48,000 vehicles recalled. However, given that Ford estimates most faulty valves had already failed, the company did not commit to replacing engines. Instead, they opted to provide an extended powertrain warranty covering up to 10 years or 150,000 miles, whichever comes first.
The EcoBoost engine is a popular choice for Ford vehicles, known for its powerful performance and improved fuel economy compared to conventional engines. The engine’s turbocharger uses exhaust gases to push more air into the engine, enhancing efficiency and power output.
This resolution brings closure to a long-standing issue impacting numerous Ford owners. While the investigation has concluded, Ford’s commitment to providing an extended warranty demonstrates their dedication to customer satisfaction and ensuring the safety and reliability of their vehicles.
