Every vehicle that ford put out with a cam phaser is experiencing issues with the can phaser. Any sae certified mechanic will verify this. This is a horrible design. Why hasn't ford stepped up to the plate and fixed this issue? I believe they are trying to bury it so that they don't have to incur the cost of fixing their mistake. Due to this issue I've been stranded on the highway. The truck looses power, won't go into gear....etc....this happens after the can phaser has activated and then I come to a stop. Then it's misfiring stalling not going into gear...you name it it's an issue. A compute read on the obd2 stayed that I had misses in ignition coils 1,3 and 7 replaced them then the teaching stayed misfired is 2,4 and 5 replaced them and all the same issues... Every mechanic I've spoken to says absolutey the phases and that they have to put a cam phaser delete kit in these vehicles do get rid of these problems. Why hasn't ford been held responsible for such a terrible design?

The time chain skips a tooth. I have been having issues with this leading to injectors and constant misfires. I was driving when all of the sudden the car started loosing power and a rattling noise started.

I have a 2007 ford f-150 with a 5.4l v8 engine. There was intermittent rattle noise (knocking) and rough idle. After the vehicle warms up and I come to a stop or slow roll the vehicle begins to shake and a loud knocking noise is heard in the engine. This is a known issue with this engine and ford denies it is. I had it fixed in september 2011, which was covered under warranty with 49,934 miles. The vehicle has started to do the same thing and currently has 82,000 miles on it. I was informed by both the dealer and ford motor company they will not repair under warranty even though this was prior issue during the warrantly time. Dealer wants approximately $300.00 to inspect to determine the extent of damage to the engine. This is safety issue as it happens during slow speeds or idle at stop lights and only way to make it stop is to shut off the vehicle or rev up the rpms. I believe the tsb was aware of this issue in 2010 but the manufacture has not notified consumers. This is a manufacturer defect and ford motor needs to repair or replace the engine at their cost.

Was experiencing a shutter similar to the feeling of a misfire when accelerating up a grade from level road conditions. This shutter was between 1250 and 1500 RPM. Took the vehicle to ford dealership who eliminated coil pack and torque converter as the source of the problem. I had taken another vehicle I own to a repair shop I have used foe several years for an oil change and when I picked up my vehicle I mentioned the problem I was having with my 2007 ford f150 and they advised that my problem was probably misfire on one or more plugs. They advised me that they had dealt with this same problem over the past few years. They proceeded to inform me that there was a major problem with replacing the plugs-they could break when removing. If that happens and it did (4 plugs broke) then additional labor costs would be added to my bill. End result a bill for $600.00 to replace 8 spark plugs. Absolutely absurd. As a part of this experience I have learned that ford mfg this engine from 2005-2007 and when this issue began to surface that they changed the engine design to eliminate this problem. Ford was obviously aware that a future problem was going to be faced by the consumer. Why should we the consumer have to bear the full expense to pay for their flawed design in this engine. They should be willing to admit their mistake but apparently it is going to take some legal pressure to get this done. If they do not step up I will never by another ford.

Evidently, ford has had a major problem with their truck spark plugs for years. Just google "ford truck spark plugs" and you will find many complaining about this along with their unbelievable stories of misery this has caused. I am continually having the coils on the spark plugs go out. I replaced one and it cost me $262. Now, I have another going out. The truck runs rough. I would replace all of them, but the ford dealership recommended not to because they said these plugs break off when trying to remove them and then tend to blow out of the engine after removing and replacing them. Then, I researched this on the internet and read about the horror stories about these ford spark plugs. I have contacted ford by email, but they said until the federal safety agency issues a recall, they will do nothing. Please help us with this.

Truck has a rough idle issue since 6k. I now have 30k. The problem happens when the truck is started cold sometimes is very bad engine shake, also when idling at a stop light engine seems to shake. No check engine light comes on even when the truck is running so bad it seems like it is going to stall. I have had it at the dealer many times and they can't find a problem they say because no trouble codes show in the computer or check engine light does not come on.
