Had our Flex for nearly two years once we hit 22k miles began having brake failures car has been in dealer 5 times they have replaced vacuum booster and check valves. When the car has been parked overnight or for a few hours the brake pedal is very hard the car will not stop.
Ford says this is "normal" operating procedure and we have to warm the car up for five minutes before driving which is totally unacceptable.
Dealer is as frustrated as we are Ford sent out an engineer who said he could not replicate the problem.
We are truly disappointed with Ford.
After purchasing what we thought was the perfect family vehicle for us, we have had numerous issues with no support from the dealership. After bringing the vehicle 6 times for font brake issues, we are finally made aware of a"service procedure(which is really a recall), but we are still waiting for the parts to arrive. We are now having transmission issue and are only being told by the dealer that is a "chip issue", but they are not willing to replace the chip. We also have issues with the rear folding seat not raising when activated and were told by the dealer to basically "live with it". Bottom line is that we are sad that Ford is not standing behind the product sold like other competitors
I had to wait 3 months to get my Flex built.
Steel Blue with Black Charcoal leather.
So far so good.
I would never think I would own a Ford.
I owned many Honda & Acura and one Volvo.
I always despite the Ford products because of safety issues.
I never felt more safe in that box!
The front brakes are kinda weird when humidity is high or wet.
I average about 18 - 19 mpg with the A/C on, and about 20 - 21 mpg when A/C is off.
At 22500 miles I had to replace the left turbo (leaked oil), an A/C line and a radiator shroud (technician broke it while trying to reassemble the turbo.)
I have been using Mobil 1 full synthetic oil since the 2nd oil change. Fortunately my Ford dealer is nice.
Wish I had the great experiences as others have posted

We purchased our flex from a dealership new (off their lot where it sat for months) in 2010.
First issue was brake noise.
After three trips back, the service department replaced the brakes.
Then the door handle paint peeled. Which the dealership told me was because of my wedding ring wear?!
Then the center console latch broke - which was covered and replaced under warranty.
Then the transmission started slipping.
That was fixed under warranty.
Already had to replace the tires @ 30k miles. The latest is the paint peal has gotten worse.
One dealership told me to take it back to the dealership I bought it from.
Ford is ford is ford.
Now - a noise in the passenger side dash.
We have owned our Flex SEL since April 2010.
We wanted to replace our 2007 Buick Terraza because it was a "hangar-queen".
We had never owned a Ford product.
We were skeptical because of the boxy look, but it has quickly grown on us.
It is a cool looking vehicle.
We have not taken it back to the dealer for anything except to rotate the tires.
I have changed the oil twice myself in 8200 miles and it does not use oil.
In the suburbs we get 19.2 MPG and on the highway we can get up to 26 MPG.
We love it.
It is reliable and the Sync System with Navigation is awesome.
