Engine started ticking ended up being cam phasers and needed new motor Ford knows its a well known problem but refuses to stand behind their products.was told it was normal engine wear which I find hard to believe at 100,000miles with recommended maintenance done to vehicle class action lawsuit would be the best for all involved when it comes to this product 7000 dollars to replace motor.

Known issue with fuel injectors caused premature engine failure at 45K mi. Too much fuel when compressed and ignited blew the piston apart. Ford replaced engine. 80K miles later similar problems and recommendation is another engine. Two 5.4L engines with less than 130K overall miles is absolutely unacceptable. Web searches say there is current litigation in progress over these 5.4L engines. I'm making a formal complaint that the basis of the lawsuit has merit. Ford has already settled a suit over the spark plugs for these 5.4L but the problems with these engines goes much deeper. I'm thankful my engine failures happened without any additional incident.

F-150 began with a ticking noise and turned into a loud knocking noise, vehicle looses power or completely shuts off while driving. Replaced coil packs, and spark plugs (one broke off due to horrible design). Basically, had to take apart the entire engine replacing several parts to still not have a drivable vehicle. Mechanic just informed me there is nothing else to do but replace the entire engine. Thank you Ford I owe about $8000 on this pos. I have already sunk $1200 into the vehicle and will now be looking at over $5000 to replace the engine.

I purchased my 2005 F150 with a 5.4L trinitron engine used in 2010. I completed all regular scheduled maintenance using the recommended products, most of it done in Ford dealerships. This 5.4L engine is a poor design and should be recalled. It has numerous problems. I had a safety inspection done at a Ford dealership and it passed even though it had a ticking sound in the engine and I had hesitation and loss of power. Replace spark plugs, I had already replaced the transmission at 98,000 miles! this engine is a piece of junk! Ford needs to stand behind its' "built Ford tough" trucks and make this right. I cant enjoy my truck!!!

I purchased my 2005 F150 with a 5.4L trinitron engine new in 2005. I completed all regular scheduled maintenance using the recommended products, most of it done in Ford dealerships. This 5.4L engine is a poor design and should be recalled. It has numerous problems. I had a safety inspection done at a Ford dealership and it passed even though it had a ticking sound in the engine and I had hesitation and loss of power. At that point, I had already replaced the transmission at 62,000 miles! now at 105,000 miles the plastic camphasers broke apart, the timing chain broke and the engine is blown!! that is unacceptable for a Ford truck to last that long and have that many problems. This engine is a piece of junk! Ford needs to stand behind its' "built Ford tough" trucks and make this right. I'll never buy another Ford.

The truck has a ticking sound inside the engine. I have had that noise since I bough it. 3 years ago I had it checked out at a Ford dealership and they said it was normal. This year on November 4, I took it again to the Ford dealership and they found the problem. Its a bent rod. The problem is that the extended warranty that I have will not cover itunless the know the cause of it. So Ford is saying its a defected part. Insurance wont cover it and they want me to pay thousands of dollars to repair it!! if its a defected part, don't you think Ford should pay!!

On highway at 60 mph engine started to miss. Was able to get it to my mechanic where he said a spark plug had failed. The plug broke when removing. He was able to remove the plug. Then due to a squeal under the hood when the engine was cold, he removed the intake and found the seal had failed, while it was apart he noted 2 leaking fuel injectors. All defective parts were replaced. In August that same year I replaced the other 7 sparkplugs, having 4 more brake off. The extractor tool worked great.

I purchased my 2005 Ford F-150 right out of the show in 2005 and first began have jerking issues 6 month later a mechanic then told me that it was related to the fuel injectors. Since that time I had to replace the transmission twice in 2008, a timing chain and bent rods in 2014 and currently another timing bent rods and debri from the oil pan. All caused from the initial faulty fuel injector issues continuing from less than one year after the original purchase in 2005. I've sent over $9500 in mechanic cost to date.

Driving on interstate doing 70 mph (in fast lane) when truck stopped/stalled and I guess from research went into "limp mode". I was unable to press the gas pedal, it just shook three times each of which slowed it down incredibly, the check engine light was on and a wrench showed up, but the radio still worked. While trying to pull over almost wrecked (memorial day weekend and I was in fast lane). Finally able to pull over to side of road hysterical, shut off and waited a minute and it started. Drove rest of way home miles* with check engine light on and ABS light on. I am scared to death to drive again. Not fun having a vehicle stall/quit whatever on interstate in rush hour traffic.

Upon starting my car that morning it backfired and white smoke exited from the exhaust which it has never done before. Once idling I put the truck in reverse with my foot on the brake and my truck rolled down the driveway. I had to depress my brakes with significant force to get it to stop. Upon checking the engine later there is no vacuum detected at the power brake assist. There is a recall on other Ford trucks of this year and model with the same issues that mine was exhibiting. Upon calling Ford they said that my VIN # was not associated with this recall. Go figure!
