This vehicle started rattling upon cold start. It has only 43K miles on it. When looking into the situation it has been a defect of this vehicle as well as many other years that Ford has failed to own up to. This rattle is due to a cam phaser pin that breaks loose and can dislodge at any time and cause the vehicle to seize up. Another owner had this happen on the freeway at 70 mph. Ford claims it is -??not dangerous-?? but obviously it is. It costs the owners anywhere from $4500-$6500 to fix. Our local service department advised us they have -??fixed hundreds of these-??. PLEASE STEP IN AND HAVE FORD ACCEPT RESPONSIBILITY FOR THE DEFECT AND CORRECT IT VIA RECALL. This is dangerous and expensive for owners. Thank you!

The cam phasers in the engine have a failure/malfunction and risk of engine damage and performance. No warning lamps are on for the this failure yet, only a very noticeable noise on startups. It has been to a dealership to be confirmed. This is the same known issue as the other 3.5 ecoboost F-150 engines in the 2017 -2018 years, I am not sure what made my VIN not fit the requirements. Bulletins 21B10,21N03,21N08 I believe are all related.

In November, dealership sends out a tech to perform a PCM Recall on my truck. 110,000 miles and never had a problem with it. After recall, check engine light comes on after less than 10 miles of driving. Tech returns, runs his program and says maybe this will fix it. Less than 200 miles of driving, check engine light comes on again. Third attempt with tech, runs program, says there is nothing he can do. Dealership says there is nothing they can do except run diagnostics for a fee. Contact Ford corporate, they give the same nothing they can do except run diagnostics for a fee. I refuse. No problems at all with my truck until they performed the PCM recall issued by Ford. Just so happens this problem is being reported on Reddit app by several other Ford owners, but -??there-??s nothing Ford can do.-??

Plastic two piece oil pan installed by factory with insufficient RTV resulting in a significant oil leak and possible fire potential as run back of oil reaches exhaust components. Vehicle is well kept and serviced regularly with less than 100k miles. Vehicle is out of warranty and down time is several days for a fix that results in using the same plastic oil pan with an estimate of $1200. Unfortunately this same oil pan will result in a similar leak in the future if fixed. Aftermarket aluminum options are available which result in a much better sealing surface. FORD please fix this issue. Oil leaking from pan first noticed during stops at red lights while idling and smelling burning oil thru vents. Ford dealer confirmed oil pan leak and suggested immediate replacement.
