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.

Bought used in wa state and live in nj now. After purchasse it rained one night and next morning entire center console, overhead lights were all wet inside. Upon further investigation determined leak was sunroof. Notified dealer and they had a glass specialist remove the entire assembly and thoroughly clean. Replaced seal with new one and claimed no more leakage. A few days later it rained again (wa well known for always raining) and again the leak was present. The dealer's response was now 'park your vehicle with the front end downhill. There are tiny slots that direct the water down the corner pillars and apparently clog easily. So parking with front end downhill will relieve the water before it can pool up to leak.

While driving, dome light illuminated and driver's seat moved to farthest position back as if exiting the vehicle. This problem is happening more frequently while driving. This problem also happens when turning on headlights or moving gear selector from park to drive or reverse. It is intermittent, but happens daily. A person shorter than I, will loose contact with break and accelerator pedals. Tapping on keys may return seat to a more forward position. As an engineer, I see this as a manufacturer's safety issue that should be resolved by the manufacturer and not the customer.

Tl* the contact owns a 2007 mercury mountaineer. The contact was driving approximately 50 MPH when a vibration was felt and the transmission began to slip gears. The failure appeared to occur more frequently in warm weather temperatures. The vehicle was taken to an authorized dealer but the technician was unable to duplicate the problem. In addition, the instrument panel and gauges would illuminate intermittently as a result of defective pixels. The front driver's side power seat would move backward and forward freely while the vehicle was in motion. The contact would shut off the vehicle and once restarted, the failures would correct independently until later recurring without warning. In addition, the headlights failed intermittently. The vehicle was not diagnosed or repaired for the failures. The manufacturer was notified of the defects. The approximate failure mileage was 46,000.

It is very difficult to see at night in a ford with a heated windshield. The lines in the windshield create glare and haze when the headlights of oncoming cars hit the windshield.

2003 mercury mountaineer 4.6l-v8: when the vehicle is not under acceleration [stop sign/signal, exiting an expressway to a surface street, coasting] the engine will not hold idle, then stall. The steering & brakes are compromised when the engine stalls. To restart the engine, the headlights go dark for a moment...this is a very serious matter. Decelerating from an expressway to a surface street, on a curved exit ramp , at night makes for an out of control situation where the driver can not see because of engine failure! I've replaced the throttle position censor [tps] with no improvement. The dealer offers replacement of parts $1500, and no guarantee of solving the problem. The vehicle is useless to me fore it is a hazard to be on the road...for me and anyone else driving near me.
