 I bought this SUV new and babied it, never missed an oil change only replaced coils and it was comfortable, had power and was utilitarian. Then at 80K miles it started misfiring and I was told it needed a tuneup and new spark plugs, but that came with a warning. This particular model was known to have the plugs cease into the engine block and break off when they needed to be changed. But I was limping around at this point anyway so I told my mechanic to proceed, low and behold my worst nightmare, plug breaks off. OK so since Ford is aware of this and has issued a notice, you are steered toward a special tool that was created to get the broken plug out, only in my case it didn't work, so they have to take the engine off the mounts to get the broken plug out, OK $2K later I figure if it's good from here on I will deal with it, still loved the truck. But soon after that Cam issues arose and a couple of mechanics said trade it in, not worth the time and expense to fix. I agreed after further research this model year and a few around it, suffer from this poor engine design and Ford should have recalled it, but they did not. Now I am part of a class action suit to try to at least recoup some of my repair costs.
