NHTSA Complaint #11612626 — 2017 FORD F-150

I am writing to formally submit a complaint regarding persistent and significant issues with the cam phasers in my 2017 Ford F-150 3.5 EcoBoost. I purchased the vehicle in December 2022 with 70,000 miles on it. Since then, I have experienced ongoing cam phaser problems, which have led to considerable inconvenience and expense. In February 2023, with 82,000 miles on the vehicle, I took it to a dealership for diagnoses. Unfortunately, this repair was quoted at $8,000. The repair involved: •Checking engine light diagnosis and verification of cam phaser failure. •Removal and replacement of timing chains, phasers, chain tensioners, valve covers, gaskets, and other related components. •Reinstallation and testing to ensure the problem was resolved. I believe Ford should cover these costs since the cam phaser issue is widely known and documented as a design flaw in the 3.5L EcoBoost engines, particularly those produced before 2021. Ford acknowledged this issue and updated the cam phaser design in 2021, but many owners, including myself, have experienced failures despite adhering to recommended maintenance and service procedures . I urge the NHTSA to investigate this matter further and hold Ford accountable for the costs associated with these known defects. Thank you for your attention to this matter.
