To be clear, this is not a recall yet. The Engineering Analysis is a required step before NHTSA can seek to compel a Ford recall. NHTSA's investigation includes data that shows an average failure mileage of approximately 70,000 miles. In June, Ford reduced the maintenance interval for models with the Fox three-cylinder to 100,000 miles, or six years. Ford told NHTSA it will also offer reimbursement to eligible consumers who previously paid to have their engine repaired or replaced due to a timing belt related issue.
