Example complaints

“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. …”

“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.”

“Truck cooling system died which caused the truck to catch fire while driving down the highway, smoke poring out, state troopers had to assist us. My daughter was scared to death and now refuses to get back in the truck even though we got a new engine. To make matters worse we spent 3000 on and engine...500 on cooling system and had the transmission reprogrammed. The truck is still have major problems and now for says it needs the transmission rebuilt or replaced. All of this is out of pocket. We cant even trade it in bc they will only give us 1/2 of what we paid for it 2 yrs ago. …”

“(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.
