When the vehicle is started, the cam phasers rattle, and yes, it is available for inspection upon request. Ford mechanics and other mechanics have stated that if not replaced, the cam phasers will eventually fail. This puts others at risk as the auto start/stop feature shuts the engine off anytime the vehicle comes to a stop. If the cam phasers failed while stopped in the road, the vehicle would not start back up, causing a rear end collision and possible injury/death to anyone on the road. The problem exists in the 2015-2018 Ford F150 3.5L ecoboost. Ford resolved the issue in the 2019 model F150 by replacing the cam phasers with ones that are built with better quality. I am unsure if the vehicle issue has been inspected by others. There have been no warning lamps, messages, or other symptoms of the problem prior to the failure. It first appeared in my vehicle around this year.

I had a slight oil leak that was getting worse over time. It got to the point one day, I was seeing minimal smoke coming out from the hood and wheel wells. I was on my way home from work one day, and as soon as I got off the interstate, as soon as I stopped at the stop light, the whole hood was covered with smoke billowing out everywhere, and the scent of fire. I quickly shut the truck off and grabbed my fire extinguisher, thinking my truck was on fire. I took it to a local shop I-??m familiar with, and he said both valve covers were warped, and there is a TSB out from Ford about this issue. The valve covers, over time, will warp, causing oil to slosh out onto the hot exhaust manifold, and everything else. He said they have had multiple 3.5 EcoBoost motors in, and everytime they have an oil leak, it-??s a warped valve cover. He told me that Ford makes a replacement valve cover with a different material, but I see this as a MAJOR fire risk! Oil getting out and combusting on an exhaust manifold, that-??s not safe at all, and could easily ignite. It really upsets me that Ford will make the new part, but not recall the vehicle to fix the issue. I had to pay $1,700 to have it all fixed and safe. I have a Foster Child and it jeopardizes his safety, along with my wife and I.

The intake manifold on this series of trucks is a commonly found failure. It is costly as it requires complete disassembly and reinstall for internal components, that lead to poor performance and eventual engine damage if not repaired. I had a SES code 2019 flag for this and required me to have >$1500 repair to resolve by a reinstall of a new intake manifold by the Ford Dealer on May 21, 2025. This should have been recalled with the vast number of problems seen online and that the dealer had this part in stock as it is so common. I was only 50d after my extended ESP warranty when it went.

Truck has been downshifting at low gears prior to this main incident. Usually at low speeds between the 1-3 gears. But today I was driving down the highway at approximately 65 mph in the 6th gear and without warning it seemed to electrically down shift into 1st gear. I describe it as electrically because the Rpm-??s dropped almost instantly for a second and seemed to reboot. Which is extremely dangerous especially on a busy highway. Not only could I cause me to crash but also others to wreck into my self and poses a incredible risk for my fellow drivers And this is the reason for my complaint. Going from the 6th gear to 1st has to be some sort of recall and or an indication of far greater problem. What is even more odd there have been no check engine lights on for any of these instances.

My apologies, I sent prematurely, case number 11664674 is already open, but I wanted to add to it. My 2017 Ford F-150 with the 2.7L EcoBoost engine has experienced recurring coolant loss and is now showing signs of internal engine damage. I initially reported the issue to the Ford dealership in November 2024, but no issue was found. On May 23, 2025, the dealership told me I need a new engine. My independent mechanic suspects cracked intake valves or internal coolant intrusion -?" a known defect in the 2.7L EcoBoost engine. This appears to be the same issue identified in class action lawsuits and previous NHTSA complaints. I feel the vehicle is now undrivable due to my fear of imminent engine failure. My extended warranty expired in December 2023, but the problem started well before that with white smoke coming out of the tail pipe upon cold starting. I am requesting NHTSA investigate these recurring issues, as this appears to be a widespread and unsafe defect affecting multiple years of the Ford 2.7L EcoBoost engine.
