Bought a 2005 F150 Triton V8 5.4L new in 2005. I have now experienced a cam phase problem which will cost appx 2500 to repair. Talking to my mechanic he said that it was no promise to fix the issue, because theese motors are known for this issue. Was told it would be easier to put another motor in so I wouldn't haft to worry about, if it would fix the problem. My brother has a 2008 Ford with the same motor and had the same problem, but his motor after having the cam phaser's replaced blew up and had to replace the motor. After reserching and talking to several ase qualified mechanics they all said that theres an issue with the 5.4 liter Triton motor. Upon calling Ford Motor Company as I well figured would happen they said that they would'nt help with the cost and that there was nor recall. Consumers should be able to get more than 100,000 miles out of a vehicle they buy. If Ford wants to keep customers happy they should adress theproblem and the goverment should be mor vigalant in assuring the consumer is protected from companies whose produt dosen;T meet standards. I would like to see the goverment to look at all complaints through a survey on this motor to find a solution for the consumer.

The contact owns a 2005 Ford F-150. The contact stated that after starting the vehicle, the engine misfire and the check engine warning light illuminated. The problem recurred multiple times. The vehicle was taken to an independent mechanic. The technician diagnosed that the spark plug was fractured and that needed to be replaced. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was 90,000.

2005 F150 goes into "fail safe mode" and shuts down while driving. It only occurred once per year starting at 65,000 miles, but now happens every 3-4 weeks at 114,000 miles. Once the engine shuts down, I put the transmission into neutral while coasting and it restarts easily. The engine light illuminates for 3-4 days and then turns off. In researching the issue, it seems to be a rather common problem with this vehicle and is usually caused by a faulty throttle body. Ford states that they are aware of the problem.

I own the above mention vehicle, there was no disclosure to me at the time of purchase of a very serious design flaw with the spark plugs that could and likley will break off in the engine during replacement and the extreme cost in changing these plugs around 900 to 1000 dollars if no plugs break off and even more in the plugs do break off or heads have to removeed to extract the plugs even worse pieces of prshell could fall into the engine cycndler and cause engine damage to around 8000 dollars now that I aware of the extreme cost 3 or 4 times the amount for routine maintence of changeing spark plugs in these Ford vehicles Ford is no help at all saying its not a safety issue I cant help it the design flaw with these long 2 piece plugs is so serious and the price gougeing of the consumer for the cost to change spark plugs is so exspenive and so bad I strongley feel that the federal gov should step inno the matter and help the consumers out and not allow Ford to get by with this extreme bad design flaw and the outragious cost they are chargeing and the fed gov should force Ford to recall all affected vehicles and mandate that Ford eat the cost of changeing these sark plugs and put in the newly develpoed plugs that are not prone to become seized to the engine and Ford shall do so at no cost to the consumer safety or not it is just unbeleivable they can get by with such a serious design flaw with such a high expence to the consumer for something that is surposed to be routine

Front end collision into the rear of another truck. Whole front end damaged through radiator, hood, headlights, bumpers etc. Airbag never deployed and upon return of vehicle after repairs, I am now getting a code 42 that the sensor is bad and after research find out there is a recall on this but for the opposite reason but also now understand there are corrosion issues with the connection of the sensor also. Hope this helps. Please advise what to do, will Ford fix this whole problem and replace with a new sensor and the wire chaffing problem? thank you in advance!

I have owned my Ford truck for almost 8 years and I have experienced nothing but bad luck with this engine and me and other Ford owners agree that this engine is 1 of the worst engines that Ford has produced and they know it.and are reluctant to do anything about it.and its costing me thousands to replace spark plugs and camphasers.my truck now will stall when put in reverse.it also has a loud ticking noise to it. I know its the camphasers again which I already replace about 4 years ago.this truck is costing me more than its worth.I only have 85000 miles on it.Ford needs to do something about this problem.me and other Ford owners of this model cant keep slamming money into something that is a complete failure from the start.this truck is dangerous and the problem needs solved.

Truck shakes vigorously at speeds over 55mph, cannot excel in fast oncoming traffic with children in vehicle! engine cuts out and jerks the whole vehicle. Misfiring. Continuously having to get towing because the vehicle fails to start all together! this could lead to injury, death, accidents not only for the driver/passengers but others on the roads as well. This issue has been brought to attention in the Ford F-150 5.4L engine more than several hundred times and no action has been taken. You can find information all over of people having the same issues, the Ford dealership I took it to told me I would need a new engine or to spend thousands to fix it and they see people back in there within the month of spending grands to fix it. Something needs done about this before people end up dying in these vehicles

The 5.4 liter engines have a design problem that's costing owners a lot of money just to replace the spark plugs. The plugs are twisting off or breaking because the block design allows the plug to extend into a hole that allows carbon buildup around the tip of the plug. When you try to remove the spark plug the bottom of the plug is sealed tight to the head therefore allowing the top of the plug to twist and not the bottom. This is happening to a lot of truck owners and some dealers won't even attempt to replace the plugs. If one breaks, it could cost up to $2000 for the repairs. I have 4 of them broke off. I have ordered the extractor kit but the back two cylinders are going to be hard to repair. I like my Ford truck but since the earlier model Ford were blowing plugs out of the blocks and now we can't get them out without an extractor, to me this is not good engineering. I would like to know what Ford is doing about this extreme cost to its customers. Thank you, randy

We bought this vehicle new in 2005. Change oil as required and did regular services. Engine started knocking and running rough. Took to dealer who stated cam phasers went out which in turn blew the engine. Dealer states new engine is required on a 9-year old vehicle with less then 140,000. Dealer states cam phasers are very common problem in this engine (5.4L trinitron). Calls to numerous other local Ford dealers reveal numerous engine repairs due to cam phasers in the engine internet research find numerous issues with the cam phasers in this engine causing complete engine failure. Ford refuses to acknowledge the problem. Dealer quote to replace the engine on a 9-year old vehicle was $7150.

The vehicle began to smell like raw fuel, particularly at stop signs or intersections. The smell appeared to be coming from the engine bay. Upon disassembly of the intake components of the engine to expose the fuel injection system, it was evident that the fuel rail had begun leaking raw fuel inside the engine bay. The fuel rail developed a speck of corrosion about 2-3mm in diameter on the top surface of the rail. The corrosion evidently penetrated the entire rail and became a pinhole leak. Raw fuel was seen leaking up and out of the pinhole. This happened on the passenger side fuel rail, which is positioned inches away from the high voltage coil pack, and above the exhaust manifold as well. Called Ford customer service hotline and was told there is no recall for it, no extended warranty program, no assistance whatsoever. Ordered a new fuel rail through local Ford dealer for $500 dollars (4 times what a typical fuel rail costs); part has not been shipped, dealer unsure if Ford has any in stock or is even making the part. Truck has been inoperable for over a week with no way to fix it.

The number 3 spark plug blew loose. The first time it happened it was just started and idling. It got fixed with a repair kit and then it happened again the next week. It wouldn't be a huge concern but there are multiple things that could happen and cause serious injury and or a fatality.

At 58,000 miles engine malfunction due to a broken valve spring. At 101,879 mile started to make a loud rattling at startup and subsided until the engine was warmed up. This continued until I reached 273,000 miles and the engine just stopped due to oil starvation and cam phaser failures. Oil was changed as required through out ownership.

While at idle my engine started to tick, so I took it to the mechanic and he told me I had a bad lash adjuster, and it was very common for this to happen with the 5,4L 3valve engine, so I went online to see if I could find any info about my issue and it seams that thousand of people are having the same issue, and how Ford will not recall the motors for repair of a major defect to that type of engine, the mechanic told me to drive it until it dies, because the cost will be the same to repair or replace the engine, powertrain.com sells the upgraded engine which corrects the three major issues with this engine, which are, lash adjusters, cam phasers, and the spark plug treads stripping out of the heads, why has Ford been able to hide this for so long.

I was traveling South coming to a intersection when a vehicle traveling North and decided to turn and hit me! he was travel 50 mph. The driver received 2 tickets at crash site also 1 ticket 3 minute before crash. I almost drove 1/3 into his car. No air bag went off in my vehicle. My hips have been hurting ever since crash. Allstate forced me to settle them. I believe if airbag went off my hips would be fine! X-rays show them 1" out of aliment and I need to continually see a chiropractor

5.4L truck always maintained and serviced at Ford dealerships. It was running perfect until it immediately began idling rough at a stop. No check engine light, we just know our truck. Took it in for a tune-up (replaced spark plugs, etc.) and oil change. Perfect bill of health - couldn't replicate problem. Engine checked out diagnostically- perfect. They suggested it could be an intermittent sticking fuel injector, so we were going to get an additive to add to the fuel tank. Didn't make it that far. Drove it home - 35 miles - got home and engine stalled in driveway. Turned back on, engine died again. Long story short - towed it back to Ford - they were able to replicate the problem - oil pressure drops suddenly (intermittently)- pointing to cam phaser, timing area of engine - end result - need new engine - this one is shot at only 68K miles - estimated cost $7,400 plus tax. Extended warranty expired. Did some internet research, appears to be a common problem. These 5.4L engines are breaking down left and right in these trucks. Don't know what changed. Had a 1999 Expedition with a 5.4L - great vehicle. Contacted Ford customer care - was told to keep all receipts in the event of a recall. An engine should not blow at 68K miles, especially a built Ford tough engine. We've owned Ford since high school and they used to be reliable, long driving vehicles.
