This vehicle is has a power train problem from day one with the 5R55S/W transmission and AWD transfer case. I purchased this vehicle where it stranded my family over 200 miles from home and it's a non running car. This vehicle should have been removed from being sold with this defect and crushed! I will never buy a FoundOnRoad Dead ford pos ever. The transmission went into neutral with out any notice. To repair the faulty drive train I will cost me aprox $2400.00 mileage 152,000 third time the drive train has been worked on.. There tranmissions were failing in a little as 50,000 miles.

I had picked up my kids from daycare and I put my vehicle in reverse and backed up. While backing up I heard a loud pop and I got out to see but there was nothing visible. So I put the vehicle in drive and as I was going down the street my vehicle axle broke and my truck hit the street in the middle of traffic. I took it to the ford dealership and they said it was my axle and my differential had broken also, am I am lucky that I didn't have a bad accident with the extend of the damage of the differential. After I fixed that and it cost $2900. That still did not fix the problem and I had to replace the transfer case. Then all three of my cadillac converters had to be replaced. I have had problem after problem and oh yeah the back rear gate has been cracked like the month after I bought it.

The dealer johnson brothers never notified me of the tailgate recall or the recall #rq8003 for the liftgate issue in 2008.

The transmission is slipping between gears, revving way higher than normal to shift and won't go into overdrive. My research of the problem shows this is a common issue on ford and mercury vehicles in this year range.
