If you had 21B10 completed you’ll get a letter in the mail for 21N03 with the details.hello posted in the general discussion about the cam/phaser etc; would love to see something from ford in writing on how long these will be covered. My original problem was 11/2020. has issue rattle come up about 3 weeks ago. truck in for repair now. I'm covered for the repair because its under 1 year for service. but would love to see the actual extension of the warranty.
