“Shortly after purchasing my Mountaineer the electric running board on the driver side began to make a grinding sound. Bought from a dealer in wa state and moved to wi state where the driver side stopped and the passenger side stopped extending/retracting. Moved to nj and we had purchased the vehicle extended warranty. Began to sound like a knocking sound with little power and had towed to dealer. There they found all 8 spark plugs fouled, driver side had 3 exhaust manifold bolts loose. …”
NHTSA complaint #10790375, filed 2015-11, 120,000 miles“Purchased in june 2009 and have had problem after problem. Mountaineer premier awd. Transmission issue, feels like you're getting hit from behind when coming to a stop. Radiator leaks. Back lift gate randomly opens, won't latch. When it rains, water comes in through the interior light mount and through dvd player. Spark plugs not easily replaced, broke off and had to be towed to a shop for removal. Gas unable to be pumped properly I can put in .25 at a time if I'm lucky. It takes 20 minutes to pump half a tank of gas. I love the features this vehicle has but this has been such a hassle.”
NHTSA complaint #10512649, filed 2013-05, 58,945 miles“I have a 2006 Mercury Mountaineer with auto running boards. The running boards seem to have a mind of their own. Both have been replaced by the dealer, the latest was 5-5-09. Today when our daughter was entering the passenger side the running board opened up like it was supposed to but closed at once onto our daughter foot. The passenger door was still open when it closed and the running board would not retract. We were very lucky not to have suffered serious injury. If she had been 7 instead of 15 I would hate to think what might have happened.”
NHTSA complaint #10268300, filed 2009-05, 45,400 miles“(day and mileage are approximate values). 2006 Mercury Mountaineer awd premier edition. In excess rainfall events, water leaks thru sunroof and down thru roof center lighting console. I've taken it to numerous places to have it evaluated. Upon receiving it from a used car dealer (respectable reputation) the sunroof leaked a day or two later. Took back to purchasing dealership and they removed entire sunroof assembly, cleaned and replaced all seals. …”
