Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

F-150 6-cyl

  • 91,000 miles


I purchases a used 2005 Ford F150 about 5 months ago. Today, Feb 28, 2014, I was leaving my neighborhood and my trucks display flashed an message reading "engine failsafe mode". my truck lost all power, no steering and died. Luckily I was on surface streets and pulled it over with no power steering and engine dead. The mechanics cannot find the cause and the engine will start but continues to turn off and the vehicle's computer shuts down. Online I read of this happening on the freeway at 65 mph. Iam now terrified that my truck will shut off on the freeway with my children in the truck with me. This seems to be a life threatening problem. I called a Ford dealership and the service dept claimed they never heard of this but can work on it if I bring it in. What is my recourse? thank you.

I was driving to town when engine started making a sound like a large compressor, stopped truck, could feel air coming from the top of the head by intake manifold, took to a garage where I was informed that the plug came out of the #2 cylinder and busted the coil pak. I know this has happened to many F150 truck owners, I know of 3 locally, and have found many more complaints with the same problem. Ford should recall, this problem.

The contact owns a 2005 Ford F-150. The contact stated that the vehicle would sound as if it was equipped with a diesel engine. The vehicle was taken to the dealer where the technician diagnosed that the spark plugs, coils, pulley and serpentine belt needed to be replaced. The vehicle was repaired however, the remedy failed to correct the failure. The dealer then stated that the camshaft phaser was defective and as a result, the engine would possibly need to be replaced. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure and current mileage was 120,000. Updated 02/11/14

F-150 8-cyl

  • 78,000 miles
After the truck passed 76000 I started to notice a tick/knock in the engine. I brought it to Ford and they told me this was normal noise for these engines, to me this was no normal. Now the tick/knock/rattle has become worse and I have been told by Ford I would need a new engine. This is a very very common situation with the 2004-2008 5.4L 3V engines. What us Ford owners would like is a recall on the cam phasers and vct solenoids. Ford has redesigned both of these parts so they know this was causing big issues with owners of the mentioned make/model/year Ford. I do not know how a company, an american company, can get away with selling vehicles where the internal parts of the engine, and american made engine, go faulty before the odometer hit's 100,000 miles. There are normal wear and tear replaceable parts on every car, but when internal engine components fail with a vehicle that is just 7 years old that is not acceptable!

This would be the second time a spark plug has popped out of the engine on my 2005 Ford F-150 with the 4.6 liter V8 engine it. The first spark plug popped out in August 2011 and now it has happened again in September 2013. I have heard that I am not the only person this is happened to. This seems to be a recurring problem in not only the 4.6 liter V-8 but the 5.4 liter V-8 and the 6.8 liter V-10. With this problem happening over and over again why hasn't Ford done anything about it. suggests that Ford insists the problem is due to improper torquing of new plugs or any number of other reasons. However many people have had the original factory spark plugs eject from the engine, which indicates there is a defect with the engine & cylinder head design. The repair is relatively easy - do not be fooled by a dealer offering to repair the issue for $700 or more. An inexpensive helicoil kit will do the trick. Also, we do not recommend simply re-tapping the spark plug threads because the threads are probably too damaged already & the spark plug may just blow out again causing more damage. Spark plug ejection is dangerous because fuel vapor starts coming out the spark plug hole, which is clearly a serious safety issue. The fuel vapor can be ignited by the loose spark plug and in fact there have been a small number of cases reported of engine fires due to spark plug ejection/blowout. I as well as other Ford owners would like the NHTSA to look into and force a recall order to Ford Motor Company to get these issue fixed, repair, and remembers all affected by this issue.

I took my vehicle in for a service engine light issue. I was told I need new spark plugs. The issue is hundreds of 2004 -2008 Ford F-150 5.4 liter engine have faulty spark plugs that break off in the head creating additional expense. The prices are between 500- 1000 to change out spark plugs. The faulty design of the plugs created this issue and Ford had not addressed this problem. Please, research this issue and help consumers with this problem. Lisle designed a tool to extract the broken plugs model # 65600 it is for the years 2004-2008 Ford 5.4 liter engines. Many dealers are aware of this problem and just charge additional monies to the customer because of faulity part design. Please, help.

When you accelerate at 40 to 50mph the engine struggles to pick up speed like it is not getting fuel. It has also stalled several times at various speeds causing me to put it in neutral while still rolling, or come to a stop, turn the key completely off and then restart.took the vehicle to the Ford dealer and to be told it was the cam phasers which will cost about $2,900 to fix were the problem. He also said the worst decision Ford ever made was using the 5.4 Triton V8 from 2005-2008. You would think if a manager of a Ford mechanic shop tells you this, I am not the only one having this problem. It also has a constant ticking noise in the engine which I was told is the tensioner for the timing chain. The truck currently has 138,000 miles.

Constant ticking noise from engine, sounds like a diesel engine, remains ticking the entire time./ when applying brakes either on a hard stop or rolling over traction in road, grinding feeling in pedal and noise and will not stop immediately.-----was told by dealership that the "ticking" was typical for Ford and the brakes was part of the antilock system, I do not think so.

2005ford F-150 4.6 Triton V8 spark plug ejected blowing out coil while driving. This resulting in a stripped head and needing to replace the engine. With research on the web seems this is a common problem with this model engine with many complaints that Ford will not acknowledge.

The coil packs and plugs have been changed on different times and the vehicle still has the same problems. Ford has to find a better solution to fix these ongoing issues so the customer does not have to keep paying all this money for the same problems over and over again. Engine lost power on several occasions and shakes when idling. Paint on front of vehicle started peeling off. All service work has been conducted a T a Ford dealership since the vehicle was purchased except for today with (2) more coil packs had to be installed at a local garage. This is apparently a big problem and something has to be done about it or Ford will find good customers going to other vehicle brands.

Bought this Ford F150 used with 95,000 miles. I was told the plugs and fuel filter needed replaced by the 100,000 range. My local garage spent hours replacing one plug and when they checked with the local Ford dealer about the problem they were told it was a long on going problem. The dealer said, they could remove the plugs but it would be $500 dollars to start and if the plugs broke off in the heads the cost could be as much as $3,000 if they had to remove the heads. Research shows me this has been going on for ever and Ford refuses to repair or recall the F150 5.4 3V spark plug problem. Build up around the base of the plugs from poor head design is costing us consumers thousands. People are getting hurt just trying to remove these plugs. I feel Ford should recall the F150 with this engine and repair or replace the engine heads with a plug that can be replaced at a fair price not this stupid thousands people are spending.

On three separate occasions, my Ford 2005 F150 king ranch supercrew 4X4 engine suddenly died while driving at approximately 55-60mph. On all three occasions, I fortunately was able to pull over to the side of the road with the engine died and no power steering. If I had not been in the right hand lane and able to pull off of the road, then an rear engine collision would more than likely occurred if I would have been in an outer lane of a multiple lane highway. After the third occasion this past week, I took the vehicle to the Ford dealership in rockwall, Texas where it cost me $700 to have throttle body/motor assembly replaced. My obd readings at home were P2104 and P2112. If not already, this issue is a fatally waiting to happen. Lots of chatter on internet of similar issues.

There is a obvious problem with the manifolds on this truck. My truck is an FX4 and rarely seen any off roading. My manifolds are cracked and the truck has been babied this results in a very annoying noise. Also the transmission had be replaced at 30,000 miles under warranty, the new one is still slipping.
