I bought this truck in 2015 had 120,000 miles on it now problems after 5,000 miles I noticed a knocking in the engine and the whole truck will begin to shake after a few miles down the road. This started at 125,000 miles. I would have to turn the truck off and turn it back on, while at a stop light. Just recently my wife and I took a trip out of state while on the highway the engine stared to knock and truck began to shake. I had to pull over turn the truck off and turn it back on. Have to do this three times on our trip, not a happy trip in the truck. After our trip the I called Ford Motor Company and told them what was happening with the truck they told me it was not there problem and would not pay to have it fixed. I took my truck to an independent mechanic who told me that it was the cam sensor or cam phasor. To have it replaced would cost me $4,000. I took the truck to a Ford dealership that told me the same thing the mechanic said and that they would charge me $2,000 to replace. They also informed the that most of the 2007 F150 that come are having the same problem. I have let it sit in my garage till Ford does a recall. I am not paying for there mistake for shoddy work.

Spark plug blew out. Mechanic replaced it for $350 then it blew out again 2 days later. Problem with Ford spark plug tearing threads out and not being able to replace spark plug without replacing entire engine. My son was on his way back to college (5hr drive) when the spark plug blew. It sounded like a shotgun! had it towed to mechanic and they replaced spark plug and 2 days later same one blew again while driving to work. Towed a second time and mechanic is searching for ways to resolve. He says we may have to replace entire engine because of threads being striped when it blew out. Ford mechanic has looked at and does not have any solutions. In researching online I have discovered that this could have potentially been very dangerous. Others with same problem have had engine fire when sparkplug blew. We were in process of selling vehicle so now we are sol! we don't have $4000 to replace engine and our family needs a 2nd car. Never again will I buy a Ford. They do not stand behind their product!

Engine was replaced in 2011 under warranty at 51,864 miles. Now at 105,662 this engine is doing the same thing. There is defiantly a problem with the engines. Ford needs to recognize and acknowledge and fix this issue with their product. If your engine does not work correctly, how can your Ford be - Ford tough!

The threads in my 07 Ford F 150 for my spark plug in one of my cylinder's went bad. And my plug leaked high pressure compressed heated exhaust. Causing my ignition coil to partially melt. Its right below the fuel rail sensor too. Its the biggest pain in the butt to fix. Used a helicoil. Didn't last too long. Trying a more permanent fix next. I was on the highway going 70 when the plug began a very noticeably loud rhythmic leak with the ignition of that cylinder. Also, when I saw the problem when I looked at the spark plug. It had already had an existing helicoil put in. And you could tell this happend way before 200K miles. Because the old spark plug was worn almost all the way down. I still have the old spark plug.

In April 2015 I began experiencing engine knocking on my 2007 Ford F-150 which had 57,532 miles on it. I took it to Ford service department and ended up spending $3,080.79 to replace camshaft, solenoid, and timing chains. I was told this work was guaranteed. Now, less than 7 months later at 61,452 miles I began hearing squeaking as I drive. Took it back to Ford and they tell me it is now the harmonic balancer is out and excessive crank shaft end play. I am told that the issue is not related to the prior repair work so I will have to spend another $3,000 or more to fix this issue. This is all after I spent over $300 in December 2014 to replace the ingnition coils. I drive mostly city driving. We picked up vehicle without repairing it this time so we could figure out what to do.

Vehicle has started to jerk around 40-50 mph. Reviews states the spark plugs and coils are the issues. Wanted to change out spark plugs, but understand the plugs breaks upon removal and very expensive to fix. Know issue by Ford Motor Company. Now I don't even want to attempt changing out the plugs. This issue should be recall or paid by Ford for replacement, since this issue is know by Ford. Issue is still ongoing, help, don't want to pay $1000 for a simply maintenance.

I've had the spark plug blow out in cylinder 6 twice while driving at about 55mph. My husband had his in 2008 F150 also. I've had to have the plugs replaced 2X. Just waiting for the fuel module and steering to go as noted in other numerous complaints.

- Byron, MI, USA

The failures stem from bad oil flow to the top end of the engine due to a flaw in design. Specifically my camshaft, cam phaser, timing components and lifters rollers have failed. The problem first showed up at 42256 miles and has since resurfaced twice even after expensive repairs. The worrisome part is that the web is filled with thousands upon thousands of similar complaints about this engine which is also in Expedition and crown victorias and probably other Ford vehicles.

Bought the T07 F150 at 28K and at 61K this happened. While driving at low gear 2nd the enging chugged a little ( lke an old diesal) took it to the dealer they said it was probably the small oil seal behind the cam. They was going to charge be 5600 for a new engine. They tried like HE11 to get me to say I didnt have the oil changed regularly. I never backed down, then reminded them that I had bought the $2700 extended warrenty (which I usually never did) they bauked and cried. Buy said that they would find another used engine, they called me and said that they found one for 3500 (or something like that) I began a long search online and found a rebuild for less and gave them the information. They decided to go with that. They ordered the engine and installed it ( well what do you know the replacement had the same prob) they had to pull that engine and get another from the company. Took an extra week and got the truck back its now at 100K and still runs well (so I know it wasnt my driving) so it had to be the incorrect placement of that seal from the dealer, which would leaked hot oil onto the engine and cause a fire. I looked at the origional paper work that they had to replace th origional wiring harness before it even left the factory.

While accelerating to enter the highway a loud pop sound was heard and the engine lost power. I had enough speed to make the break-down lane. The sound was coming from the #3 cylinder on the right side of the motor. 4.6L V8. These were factory plugs and the vehicle is maintained every 3000-5000 miles.

- Derry, NH, USA

The engine was replaced in 2012 with 53,000 miles on the truck due to a significant knocking coming from the engine. The truck was still under warranty so it cost me nothing to replace. The engine started to make the same sound in Feb 2015 (84,000 miles on the truck, 30,000 miles on the engine). I had it taken to an auto mech and they told me one of the spark plugs ejected from the engine and ripped all the threading out. They also found that on E of the cylinders broke off the crank shaft and ceased. The engine has to be replaced again and the truck is no longer under warranty. Both the original dealership that replaced the engine and the auto mech that I had the truck taken to, are researching if the parts are still under warranty.

Truck jerks and jumps because the cylinders aren't firing. Just spent $1000 for new plugs a few months ago. I have had to replace several coils in the last 3 years. Problems started around 100K miles.

While driving on a New York interstate at approximately 60 mph in a snow storm, my truck started to miss. It then slowed down and shut off. I did not have enough time to make it to the side of the road. A truck stopped and I had him push my truck to the side of the road, causing me to have damage to my truck. Found out that the fuel pump driver module failed. It is located above the spare tire and due to a design error, water and road salt get trapped between module and mounting brace. It erodes out from the bottom side and the mounting bracket. When replaced, was informed that it is a redesigned component, lifting it away from mounting bracket. If I had not had enough room between me and the tractor trailer traveling behind me, or if I had another vehicle traveling next to me, it could be a total different outcome. I know for a fact, that part component is extended in states where there is a high risk of salt corrosion, and believe that a safety issue like this should be one of them. Sitting on a highway in a snow storm is always dangerous.
