- Spring, TX, USA

The truck started missing at about 96,000 miles. Thought it was plugs. Missing got worse, losing power, vibrations in engine and started shutting off when stopped at a stop light/stop signs. Took it to dealer where it was bought new and they said it was the cam phaser gear. Major repair. Just payed the truck off 2 weeks before I took it to dealer to see what was wrong. In doing a little research I see this is and has been a problem for many years. So I now have a truck that looks almost brand new that I can't drive.

- Diamond, OH, USA

I was driving on the highway when my truck randomly began to sound as if it was in high idle like if I had it in neutral and was still pressing on the gas peddle. A wrench light came on as well as my engine light and I immediately lost power. Once I pulled over and placed it in park all the warning lights disappeared and my truck was fine again. Then it happened a second time but this time it almost caused the person from behind to hit me. I finally got to my destination and my truck was once again fine as if nothing happened. Few days later I was on the highway and it again happened. This time I had to utilize my insurance and have my truck towed back home. It has been an ongoing issue with my gears wanting to slip or feel like they don-??t want to engage. Even with my truck constantly shifting hard. I contacted Ford and I am being told that ultimately Im still responsible for charges. I know this is an ongoing problem with the manufacture and I know I am not the only person with an f150 having this issue. I am writing this complaint because it can be a dangerous situation, especially around heavy traffic.
