NHTSA Complaint #11709452 — 2018 FORD EXPEDITION

At approximately 100,500 miles, my 2018 Ford Expedition XLT 3.5L EcoBoost developed loud rattling noises consistent with cam phaser failure. Zeigler Ford confirmed the failed cam phasers on October 20, 2025. These phasers were previously replaced on the vehicle at 51,000 miles on February 10, 2022, at Al Piemonte Ford under the Customer Satisfaction Program 21N03. They used the old phasers HL3Z-6C525-CD which are known to be defective rather than the new updated phasers ML3Z-6C525. Cam phaser failure can cause engine misfires, loss of power, and potential engine damage, creating a serious safety risk, especially at highway speeds. This issue has been reported by multiple Ford Expedition owners, indicating it is not isolated. I request that NHTSA investigate whether this defect warrants a recall or expanded coverage for vehicles like mine that exceed CSP mileage limits. My vehicle has been properly maintained, and the failure is due to a known defect in the 3.5L EcoBoost cam.
