I purchased a Ford F-150 in 2006. I am at my 100,000 maintenance and the spark plugs have to be changed. I spoke with a representative at the Ford repair shop who told me that I would have to bring my truck in 24 hours early to soak the plugs because they will break in the motor and I will have to pay to have them removed. I followed there instructions on Monday morning and took the truck to them. They called and informed me that they would have to take the head off my motor to remove the plugs at a considerable expense to me. It does not seem fair to me that if Ford mechanics put Ford plugs into there Ford trucks and when there Ford mechanics try to remove the Ford plugs from the Ford vehicle they break and I have to pay for the damages.

While driving my 2006 Ford F150, the gear shift cable melted due to contact with the manifold. This cause the truck to stop. I could not start the truck again. This happened when I backed out of my driveway. The truck was taken to the Ford dealer by flatbed.

The contact owns a 2006 Ford F-150. When the contact applied pressure to the brake pedal, he heard a loud scraping noise. While driving approximately 50 mph, he experienced unwarranted four wheel drive engagement, which caused the vehicle to decelerate. The dealer replaced the iwe solenoid and the actuator. Several days after the repair, the failure resurfaced and became progressively worse. He took the vehicle back to the dealer, but they were unsuccessful in locating the cause of the failure. The failure mileage was 21,000 and current mileage was 33,387.

I drive a 2006 Ford F150. In July 2007 I started hearing a grinding noise coming from my front wheels. I brought it to holman Ford in turnersville New Jersey. They replaced auto 4WD vacuum solenoid. Now 15 months later the noise is back and they said their parts and labor warranty is only good for 12 months. I know other people who had the same problem but they said there is no recall. It is obvious there is a defect.

Once, while shifting from park to reverse and also once while shifting from park to drive the engine has gone to (nearly?) full throttle. Both times I was able to avoid and accident by standing on the brake and shifting back to neutral (throttle returned to idle).

2006 F150 fx 4 -4X4 super cab 5.4 L. I traded the exact same truck in an 04 model year for this 2006. Ford has refused to fix ( for 3 model years ) : drive train vibration, drive train howl/whine. The 04 was in the shop 6 times with no fix. My 06 in the dealership now. I haven't made the first payment or the first oil change. Problems not present on test drive. Started at 500 miles. Other problems include : brake pedal is mush. It never firms up. It will go to the floor. Doors wont shut without slamming. Super cab doors wont shut tight without pushing top in. My best fuel economy is 13 mpg highway with the cruise on. The "new" F150's are a disgrace to the Ford name. $ 38,000 P.O.S. !! my last Ford.
