Mercury Mountaineer hesitation problems

Filed Aug 28, 2018 · Engine · 80,000 miles · NY

Car ran rough & hesitated/surged upon acceleration. Apparently this is a common ford problem involving premature spark plug break down in the ford triton engine see ford spark plug class action settlement. Shultz ford in nanuet ny diagnosed the problem as faulty plugs, there was also a risk of breaking plugs upon removal. I had them do the repairs at a cost of $788. Later I found that there was a settlement, however my car was not included even though it had the same engine as the cars/trucks/ SUV's that were included in the settlement. Ford customer service said there was nothing they could do re: reimbursing me for the repair expense as my SUV was not included in the settlement. They suggested I file this complaint. Can I get some satisfaction?

Two problems...first whenever I shift into reverse there is a hesitation and it takes longer than it should to reverse. Im also experiencing a jerk before I come to a complete stop. Second ..the back of my lift has a crack from the bottom of the window to the mercury symbol and then it continues down under the symbol. I've done some research and there re lots of others with these same issues. I only have about 70000 miles on it.

I purchased the 2006 mercury mountaineer in july 2011. When I went to take the kids on vacation the car hesitated and stopped on the highway then felt like we were rear ended, very dangerous with the hesitation on acceleration almost crashed. Called the place I purchased they have now replaced the torque converter and reset the TCM the vehicle is even worse and they also have had it for 34 days on and off. Called ford they said they have no program to fix and will not replace the transmission which needs to be replaced. The dealer reports without a bad code even though they know the vehicle is hazardous they cannot find the problem to fix, I said please just replace the transmission and unfortunately to no avail I have purchased a $18,000 hazard that I only was able to drive for 30 days, traded my other vehicle and gave them $1600 cash for downpayment I just want my vehicle fixed....

When coming to slow stop, the vehicle will lunge forward before completely stopping. This behavior started several months ago and was very random in the beginning, but has become more and more frequent - almost every time I come to complete stop. Vehicle also hesitates when gas is pressed and then surges forward. That behavior is very random at this stage, but car has done that over the past year. Because of the "lunging" at stops, I have taken vehicle to repair shop and they indicate the vehicle's computer needs to be updated. This appears to be a common problem with this make/model/year.

I have a 2004 mercury mountaineer and the transmission is very dangerous, my wife started to back up and put it in reverse and the transmission hesitated and then slammed into reverse causing her to jerk and then her foot came of the brake and hit the gas pedal causing her to ram a parked car behind her, and that was just the first time .the next time I myself was in the vehicle and it done the same thing except there was not a car behind me to stp me and I went over a embankment and if not for a tree I would have gotten hurt bad , the tree stopped me from going to the bottom , and it still to this day will slam into reverse, nothing has been done with it yet . I have read on the internet that alot of mercury mountaineer owners are having the same problem this is going to get someone killed if it has not already.

O/d light blinking - hesitation when shifting while driving occurring each time the vehicle was operating - took it to transmission expert who fixed for 2000 because dealer quoted 3500! Trans guy asked if it was 2002 or 2003 as soon as he heard the make and model. Cracked liftgate that was fixed in the first year of owning the vehicle but second time it cracked the dealer would not fix it and quoted $700 ford would not fix either. An obvious defect!

2006 mercury mountaineer transmission problems. Hesitation, funny shifting. Could get someone in trouble by the random shifting problem. Ford dealer I went to said they had never heard of the problem. When you google this it is a problem thanks

Vehicle's transmission "clunks" or hard shifts, when slowing down and coming to a stop, or at low speeds. Surges at stop lights, or will hesitate when the gas pedal is pushed. This has been an ongoing problem since I purchased the vehicle in 1997. I have taken it back to the dealer numerous times, and they tell me that 1. Nothing is wrong with the transmission or 2. They have downloaded a new program for the computer. I know there is something wrong, but no one will fix this. Now it's 4000 miles over warranty, and the problem is getting worse. Sooner or later this will cause an accident.
