Vehicle transmission will instantly drop to gears 3 to 5 (limp mode from what I have researched) & wrench light comes on. Very dangerous on the interstate traveling at 70mph+, seems to happen more frequently on hotter days. You can park & turn off vehicle, then crank back up, & it is out of limp mode but transmission is sluggish. Initially it was happening once per week on avg, now it is a toss up on each drive I do whether it goes into limp mode or not.

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.

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 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.
