Recently reported ELECTRICAL SYSTEM problems on 2005 Ford F-150

Have owned this truck bought new, 2005. have used sparingly only 15k + miles. over the years i have experianced a number of occasions when it tried to accellerate when i went to brake. first thought it a quirk or floor mats. recently nearly trashed a parked car while backing ito a parking space. continued to accellerate dispite standing on brake. there is no longer any doubt that this is a problem with sua, sudden unintended accelleration, that ford has never admitted. i have made sure i am off the gas pedal and the floor mat has been removed. this happens when the vehicle is moving and when trying to brake!

The brake warning lite remains on. i'm told by my mechanic that it is due to a broken connection in the dash board circuit board and he said it is a relatively common fault. repair requires removing the entire dash board and replacement of the circuit board.

My 2005 ford f150 truck has had so many problems & some replace twice & im over it im about to have a heart attack now it sounds like my aculator again with the sound of metal scraping on the ground and when i switch it to 44 the sounds stops .but if its not in 44 the sound stays and it is loud ! i have spent so much get my truck fixed and what upsets me is i take care of my truck change oil spark plugs everything since purchased in 2005 brand new and im over it something needs to done with all these parts defected and it will continue until something is done.

Purchased ford f150 from old saybrook ford, feb. 16. the truck has the 5.4 engine which has numerous complaints of engine failure. driving on route 1 when truck eccelorates or loses power. when we bought the truck the chain guide was broke and eating through the case. spark plugs get stuck in engine or propel them selves through the truck hood. dangerous engine to have on road. i owe 8000.00 on a truck that now needs 4-6000 worth of work.

Vehicle went into "failsafe" mode on two separate occasions within the last year! and most recently, two weeks ago! both at highway speed on two different interstates in florida! very dangerous, and hard to control vehicle to "limp" to a safe place to stop! many possible causes from electrical, fuel, or engine issues that are well documented on many internet sites and f150 forums! also rust issues on roof of vehicle in rain channels! very common,and very poor design!

Fuse 14 controlling abs module, dtr sensor, reverse lights, pcv heater, air conditioner compressor, cruise control deactivator switch and daytime headlights was repeatedly blowing. truck was serviced by dealer on 3-23-16, replacing the a/c compressor. replacing the a/c compressor did not resolve any issues. the truck was returned to the dealer on 4-6-16 for the same issue with the same fuse. the dealership replaced the fuse and performed diagnostic tests on the truck, then informing me that they could not diagnose or locate the short. the dealership informed me that i would have to drive the truck until the fuse started blowing more frequently. the first time the truck was driven after work was performed the cruise control was not functioning properly. the truck engine would surge as the truck went down the road with the cruise control on. the issue with the cruise control happened on 4-9-16. on the morning of 4-10-16 the truck was driven approximately 4 miles and parked in the drive of my home. after entering the house the alarm was heard sounding on the vehicle, at which time i stepped outside to find the truck on fire. the fire seemed to have started on the ...

A number of wires leading from the body into the driver's side door have been cut/worn possibly due to contact with the inside of the door. the rubber and plastic parts meant to protect the wires were also cut/worn. this has led to complete failure of all electronics in the door including power lock, power windows, automatic shutoff of radio, door chime, keypad, and mirrors. discussion with ford dealer indicated that they have seen this problem in the past.

I started the truck and then turned on the rear defrost, which i rarely use. it was about 55 degrees outside. after about 2 minutes i heard a hissing noise that lasted for about 5 seconds and then a heard loud pop and then the windshield shattered. many other articles on the web indicate that this is a known defect with the rear defrost. i called ford and they will not offer and compensation to have it fixed even though it is a known issue. my daughter was in the back seat and got glass in her hair. *tr
