Ford designed the factory spark plugs as a two piece design. Once the truck requires a tune up the current spark plugs break in half as they are removed causing an addition cost for extra labor and special tools designed to remove these plugs. I took my truck to the Ford dealer who then broke 6 out of 8 plugs upon removal at an extra cost of 80 dollars a piece. The tune up which only includes the removal off the old and the installation of the newly designed one piece spark plugs ended up costing me 1000 dollars. These spark plugs also break inside the engine causing a loss of power and possible damage to the catalytic converter.

When taking my vehicle out for test drive after putting new brakes on. While driving an spark plug blew out. While checking online I found that this is a major problem. I was very upset to find out from the dealer that it's gonna cost $585.70 to fix one spark plug and replace coil. I asked about replacing all the plug and they quoted $900 to do all of them. As a retiree of Ford I think this is crazy. They tell you in the manual that the plugs are good for 100,000 miles. The mechanic said there is no guarantee that this won't happen again even if we replaced all the plugs. I'm thinking of trading my truck off and am considering another brand.

Ford fuel pump driver corrodes badly causing no start and/or total failure of engine power. Reduction of power or engine stalling can and will happen at highway speeds. When engine stalls driver can lose power steering power brakes and control vehicle. This is known by Ford. Ford along with a aftermaket company has redesigned the part. The updated part has standoffs along with a protective coating preventing corrosion. The corrosion of the part happens faster in the salt belt states. I replaced mine and the part had a hole in it letting water and parts of metal inside unit. I still have part if needed. Do an internet search and you will find allot of examples of this issue. This issue affects millions of vehicles.

I was pulling out into traffic when the engine wouldn't respond. Luckily it wasn't on a highway the on coming traffic had enough time to avoid me. There was no warning I thought the truck had died and went to restart but the engine was idling. I then put the truck into low transfer and was able to move to a safe place by idling until a tow truck could remove it.

Cross-reference Ford tsb 07-13-5: water leak from ac has flooded the passenger floor pan and all associated carpeting and padding. Significant health hazard exists in warm climates due to the proliferation of respiratory hazards including but not limited to legionnaire's disease. The item should be a recall for this reason. I have lost use of my truck due to the inability to sufficiently dry the padding - I have had the vehicle drying for one week in hot Florida sun to no avail.

Ford factory spark plug breaks within the head causing potential internal engine damage. An extremely common issue that has lead to the invention of a special tool used just because F the issue. Commonly reaching hundreds and even thousands of dollars to repair. Ford has changed their tsb from changing plugs at 100K miles to 60K miles. However by the time a issue was noticed many of us owners have over the 60K mile mark.

2005 Ford F150. Consumer states engine shuts off and vehicle continues to go into "fail safe mode" the consumer stated there were times when the vehicle would re-start, and other times it wouldn't. the consumer stated several components such as the fuel filter, catalytic converter, fuel pump module, throttle body, and crankshaft position sensor were replaced to try and rectify the problem. The engine began to misfire and the check engine light illuminated. The consumer stated it was finally determined, the casing on the crankshaft position sensor wire had rubbed through and was shorting out on the ac line running along the right fender well. The consumer stated at some point when his vehicle was being serviced at the dealer, a cover was removed from the far left wiring harness at the PCM, which permitted water to run down the inside of the wiring harness and shorted out the connector.

Yes my 4X4 is not working and I have read over 300 post easy about the same problem people are having. Thousands of people are having the same problem I have had with my truck. Obviously if there are that many people with the same year of truck and same problem why isn't Ford doing a recall? they say the problem is the iwe, solenoid, the problem why it happens in the first place is there isn't a rain cover over the solenoid underneath the hood. I do believe that this is a huge safety hazard and almost caused me to be in an accident about three weeks ago because my four wheel drive went out! Ford please do a recall before someone gets hurt or even die! I do believe that Ford should be responsible for this issue and have a recall to get these vehicles fixed.

The problem started in 2010, it now has happen three times this year my 2005 Ford F-150 supercab has without any warning, either lost all power or the engine was reduced to idle RPM at highway speeds. A total of five times this has happen since I bought the truck. Its happen in all typs of driving, highway speeds, city driving, acceleration and at a steady speed. I have had to maneuver across busy freeway lanes while coasting. In three of the incidents in which the engine stalled, I had to accomplish this without power steering or brakes. In another incident, the engine was idling so P/S and P/B were functioning, but there was no response to throttle inputs for acceleration. The check engine and "wrench" warning lights were illuminated on the dashboard. After turning off the ignition switch, the vehicle re-started and I was able to continue, the wrench light went off after restart, but the check engine light remained illuminated until I have it reset. I been very fortunate that I have not been in an accident. This problem is intermittent and comes with absolutely no warning, it is clearly a safety issue. I now will not let my family drive the truck.

The contact owns a 2005 Ford F150. The contact stated that while driving 60 mph, a loud noise was emitted from the engine compartment. The contact mentioned that the failure recurred twice. The vehicle was taken to the dealer who diagnosed that the spark plugs were not torqued correctly, causing the spark plugs to be spewed from the engine block. The manufacturer was made aware of the failure who did not offer any assistance since the vehicle was not included in any recalls. The vehicle was repaired. The failure mileage was 87,000 and the current mileage was 120,000.

Starting with a service on 2/19/2008 the truck had been idling really rough and making a ticking sound when started. At that time the Ford service department stated that the noise went away with factory oil and filter. This problem has persisted up to and including when we took it in last week where we were told that this could be fixed with thicker oil, and to return when it is time for our next service. The second issue has persisted since mid 2010, it is a foul fuel smell coming inside the cab, through the ac vents when the truck is started in the morning and when idling. We have been told over and over aging that nothing can be found and they cannot smell it. We were also told that they drove the truck around during a service on 8/17/2011 to see if they could smell it, yet our miles in and miles out on our service records both state 47,771. Not sure how they drove it without changing the miles. Our truck barely has 50,000 miles on it, it is serviced regularly yet it idles horribly, smells of fuel and gets 7mpg. Something has to be wrong!

Vehicle misfired on acceleration on highway. Was aware of spark plug ejections w/ my particular year and model after going through camshaft phaser repairs. (2005 F-150 w/ 5.4L Triton engine). Mechanic suggested replacing all factory spark plugs w/ new designed spark plug kit to eliminate ejection problem. I did so at a cost of $831.52. Costs to date $4729.25 within the last 2 months on a 2005 vehicle. Unacceptable. Researched on internet and found this to be a very well known problem. No mention of it from the dealer upon purchase. Ford has turned their back on this (and the camshaft phaser defect). I am a small contractor whose livelihood depends on this vehicle. The purchase price of $35,890 plus tax and license was a huge investment for me (I paid cash and drained my savings so I would not have monthly payment). So these additional costs to an almost new vehicle have drained my account again.

Camshaft phasers failed so engine would not idle, causing a very dangerous situation at stop signs having to constantly rev engine to keep running. Repair cost $3,897.73. Through internet investigation have found my particular year and engine (5.4L Triton) has a history of this failure. Told that a non-motorcraft oil filter can release debris that clogs a lubrivation port in the cam phasers which in turn destroys them. No info. Of this sort was ever relayed to me on purchase of vehicle. I have no reason to believe I have ever used anything but a motorcraft oil filter. A 2005 vehicle w/ a $3900 mechanical repair is unacceptable. Have contacted Ford until I have exhausted my attempts. They finally told me this was the end of our communications.
