I actually also just joined this forum just about this issue. I purchased my 2009 Ford Flex from the local Ford dealership in the middle of December. I have had NOTHING but issues. They sold me a car in which the rear left seat didn't fold to allow access to the 3rd row, the passenger seat was broken (would not move), a/c ran hot at idle, driver's window makes a horrible scraping sound when you lower it, and is missing a seat buckle in the middle row, rendering that seat useless. They also only sold me 1 key and didn't know the code to enter the car. Most of these issues I found out while checking the car out while it was on the lot, and having them put in writing their intent to repair these items. The refused to give me a 2nd key. Who buys a 7 seater family vehicle and only gives 1 key? And the car was nearly out of gas when I left the lot! So the day after I bought the car, I returned to have the work done for these various issues. They ended up keeping the vehicle for an entire week. Many items are STILL not repaired, I am still missing a seat buckle and the window scrapes but the main issue I know how is the vehicle completely overheated last night.
I was running an errand to a friend and was letting the car idle on the street while I picked up an item from my friend. She said to me, is that smoke? I immediately ran to the car, turned it off, grabbed my purse out of the car and backed away. I noticed when I turned the vehicle off, the temperature gauge was set on H and the temperature light on the dash was on. My vehicle had just overheated. Also all over the road was some sort of liquid and lots of it. It was dark so I was unable to see what it was. I called a tow, and then had to call the dealership to ask to hold the lot open for me (it was past 8, which was their closing time) and by chance I got my sale man on the phone and he told me he would.
Today my service advisor told me it was the cooling fan, as I suspected from reading these forums. He needs the car a few days to make the repair. At this point I've had my car TWO WEEKS since the day after I bought it they needed it a week for repairs. He wants to charge my ESP plan for this, $100 deductible. I told him no way, this is a Ford Flex issue and I am not paying for it. We had a disagreement and he told me he'd talk to someone (not sure who) about what to do, but he basically played dumb, saying he's never heard of this issue. I told him there was a service bulletin about this VERY issue, and he didn't even know what that was.
At this point I am so mad about buying this vehicle. My family has always been a Ford family (2 relatives retired from plants) but this leaves a very bad taste in my mouth.
Prior to the vehicle overheating, the fan had been running after the car was turned off (loudly) and the a/c would run outside air at idle when I first started the car. I told the dealership when I bought the car about the a/c not functioning correctly and they told me they could not replicate it. I bet if they ran the codes they'd find a fan code!! I am now also concerned about engine damage caused by the overheating.
