Most recently, (not including rear end replaced, reverse band on trans replaced, blown spark plug out of engine block) my truck has started to stall out for no reason that I can fathom,1st time was at 65 mph on a major highway, now more recently at lower speeds, coming to a stop at stop signs lights ect, turning street corners at lower speeds, or coming to a stop in my driveway. I see many complaints of this same problem in forums with no cause or repair that seems to be a root cause. Please help !

I noticed that the cruise control started shutting off without ever touching the brake pedal or off switch. Then sometimes it would work fine for a few minutes then just shut off. When it does that it will not come back on again till the next day. I then checked the console shifter, I was able to shift of park with out pressing the brake pedal and even engine in off position. I am worried that the truck may jump out of park and run off and hit something or someone.

Power loss and surge in flow of traffic at 65mph. Sudden stop and loss of power in traffic. Traffic had to come to halt around me. I had to stop vehicle and attempt to restart several times to restart. This is a known issue with this year and model of Ford and needs to be recalled. I have not had it happen at these speeds and it was terrifying.

I was on the expressway and set my cruise control at 74 mph. When I pressed my brake pedal, the cruise control wouldn't disengage and the brake pedal became hard like a rock. I then pressed the off button to turn the cruise control off but it remained engaged. I pressed harder on the brake and was able to slow down to 65 mph but as soon as I released the brake the vehicle gradually sped up to 74 mph. I exited the freeway and had to put the truck in neutral to stop. When I did this the engine raced to 4500 RPM. I then put the vehicle in park and turned it off. When traffic cleared, I restarted the engine and it raced to 4500 RPM. I put the truck in drive and made a left turn into the center left turn lane and had to put the truck back in neutral while I waited for traffic to clear so I could merge. The engine raced to 4500 RPM. When traffic cleared, I put the truck back in drive and the cruise control finally disengaged. However, at this time I smelled smoke coming from the engine compartment. Since the cruise control was disengaged at this time I decided to re-enter the freeway and return home. I haven't tried the cruise control since then but I smelled smoke again this morning when I took it into the dealership. I should note that my vehicle is a 2004 F-150 heritage edition which in essence is identical to the 2003 F-150. The 2003 F-150 was recalled for a problem with the cruise control but according to Ford motor the 2004 F-150 heritage wasn't. both the dealership and Ford customer service have told me that I must pay for the repair since the vehicle is out of warranty. I think it was just an oversight that the 2004 F-150 heritage wasn't recalled along with the 2003 F-150. This incident could have been much worse than it was.

While attempting to accelerate onto a highway my vehicle sputtered and I was unable to get up to speed in a reasonable amount of time. Fortunately I was on a 4 lane highway and the approaching vehicles were able to avoid me by pulling into the passing lane. I brought my vehicle in for service and a corroded fuel pump control module was responsible for the hesitation. According to my mechanic, he categorized the problem as defective design. The module is mounted in a area susceptible to corrosion. This is a relatively easy fix however in my case the spare tire carrier had to cut off to access the module.

  • 1,000 miles
When the speed control is engaged it works fine on level or climbing highway, but on the downhill side, the speed control does not hold the vehicle to the speed set. The vehicle speed keeps increasing depending on long the downhill section is and the brakes must be applied to slow the vehicle down. It was taken to the dealership at the time it was discovered and I was told there was nothing wrong with it and that I had to take it out of overdrive for the speed control to work properly. However, I tried this and the speed control did the same thing, increased speed on a down grade. On every other vehicle I have ever owned, the speed control, when engaged, controlled the downhill speed to the speed which was set.

At 50,000 miles, and earlier, the engine warning light came on, the truck lost all power, and the power steering failed. Upon taking the truck to the dealer, it was determined that the throttle body was defective, and needed replacing. Needless to say, I think that this should not have happened at such a low mileage and should be covered under a recall. Thanks for allowing me to vent.

The contact owns a 2004 Ford F-150. The contact was driving approximately 55 mph when there was an abnormal increase of acceleration to 80 mph for a brief moment. The vehicle then resumed normal operation. On a separate occasion while driving, the brake pedal was engaged with a rapid increase in rpms, followed by an unexpected increase in speed. The gear was shifted into park in order to stop the vehicle. The failure recurred fifteen times and was taken to an authorized dealer who was unable to duplicate the failure. The contact planned to take the vehicle back to the dealer for a second diagnosis. The manufacturer was notified of the problem. The approximate failure mileage was 24,000...updated 04/16/12 the consumer also stated there were times when he started the vehicle and the engine raced at high RPM's and it was not related to the engagement of the choke in cool or cold weather. Also in relation to increased RPM's above after the vehicle was shifted into par, the engine continued to race at 5,000 RPM's.

As I was parking my F150 I put my foot on the brake and the car began to accelerate on its on. I applied full force on the brakes but the truck continued to accelerate. I quickly put the car in park and shut it off so it would not hit the car in front of me. About an hour later I restarted the truck and drove home fine. This also happened once about 3 years ago, as I was approaching a stop sign. The garage found nothing.

I was driving when I heard a loud pop! at that point my driver side window rolled down and couldn't be rolled back up. Ford said they would look at it for $200 and that was just to look at it. I tore into it myself and found the window regulator to be broken. Ford wants to charge me $198 for the whole assembly. This I believe to be rediculous. Also my passenger side window does not want to role up with the passenger side control so that is inopporative. One more thing my cruise control doesn't work half of the time. My major complaint though is the window regulator as this seems to be a major problem with Ford components and even the Ford mechanics I talk to say this is a big problem.
