I am having the same problem, engine running rough, check engine light came on. 2008 Edge. 16,000 miles. The car has been in the dealer for 7 days. The top end of the engine is torn down, got to see it today when I went to the dealer to get some belongings out of the car. Dealer is waiting for redesigned parts. Variable valve timing is the problem, a number of sensors including oil pressure must be replaced. Dealer tells that I am number 7 to recently have the problem. I called Dearborn and asked Customer Service if this is an epidemic problem, are there any campaigns on this? Answer was no. I explained I am very concerned that a car in it's 2nd year of warranty with only 16K miles on it is having this kind of major problem and it appears that a number of other owners are as well. Just getting hte car back tio the dealer for service presented a drivability/safety challenge since the car was quite sluggish.
My concern is that this happens again in another 16k miles after the car is out of warranty. Hey Ford if you are watching this blog, may I suggest you get a service campaign going on this before someone has a real problem due to compromised performance trying to get their Edge to the dealer when the auto valve timing is malfunctioning.
