2006 Mercury Mountaineer driving along around town or highway and will just loose power without warning after the fact then the engine light comes on along with a red wrench or an orange wrench, first place I had it to said it was a negative battery cable that was loose so they tightened the cable, took it home stalled out on me, took it to another dealer said was reading that it was the fuel pump driver module drove very next day stalled on me once again taking it to the Ford dealer itself said could be a number of things one is that the mass air flow has exposed wire which they will be fixing that and cleaning out the electrical throttle body and see how that is if not then they will try replacing the torque convertor clutch circuit for one this needs to stop being a guessing game I'm not a millionaire I used my 401K to purchase this vehicle, its such a huge safety issue while on the main highway and just up and stopped on me luckily I was able to drift over to the side of the road in the meanwhile with a tractor trailer coming up behind me with several other traffic huge safety concern Ford contacted by the one garage and they "wasn't sure" what it could be, well it stops anytime while driving anywhere such a huge safety hazard someone has to know something without having to just "guess" the situation. Also every time it rains the water seeps thru the sunroof and the overhead light you can see it came thru the liner itself when it dries up, so heartbreaking because I fell in love with this vehicle that I have only had for about a year and half.

Mountaineer premier AWD with just over 150,000 miles. Went to raise rear (third row) electrical seat on driver/left side. Makes a slight clicking sound and will raise up about 1 inch, then just stops going up with sounds still heard. Further investigation shows a motor in the center along a gear shaft which must raise the seat. The motor is whirring like it is functioning but the shaft doesn't move. There is no way to manually fully raise the seat.

The rear window hinges disintegrated and the rear window fell off. We were not in motion and just in lifting the window it cracked off. In researching there was a recall in 2004 for the same exact issue for the same make/manufacturer. The problem however was never fixed in the years that followed and sadly there has been no subsequent recalls if I small child was behind the window they could have been seriously injured or if the car was in motion the window could have cracked and fallen off. After calling the Ford Motor Company they responded that for my make and model year the recall doesn't apply but to hold on to my receipt just in case..... please see attached pictures of the hinges, the parts alone cost over $150

Owner of a 2006 Mercury Mountaineer. I purchased my vehicle in February 2010. The retractable running boards do not operate properly. Sometimes up then down one up the other down. Disconnecting motor or pulling fuses are not the answers. Steel mixed with aluminum pins is bad but can be fixed. I reviewed numerous on-line complaints and wanted to know why this item has not been recalled. The boards half way down is a constant trip hazard when getting in and out of the vehicle. 1500 dollars to replace the entire unit is the wrong answer. This is clearly a design problem on a great vehicle
