3 Power Train problem of the 2007 Mercury Mountaineer

Failure Date: 08/06/2022

I was driving on the expressway and my truck just shut off. The car panel illuminati to a check engine light and a wrench. I had to put on my caution light and make it to the shoulder. That was scary. I sat for 10 minutes before it started back up. I've taken it to the dealership and all they did was guess what the problem could be. They said it might be the fuel pump or something electric or the computer. That's not doing me any good, because I'm still having this problem.

Started losing power ,did not want to go pas 30 miles per hr ,then it ramed up and came to a stop with no acceleration ,I shut it off then start it again and was able to get home at a low rate of speed while continuing to have these problems, another day while far away from home the engine rammed up again minimizing my speed as the transmission was slipping and not go fast then my o/d over drive went on flashing a light ,while the engine kept steady at 20-30 miles per hour while accelerating increasing no speed ,now my SUV will not run wright, it will kick into gear at times constantly and cause problems driving safely ,this is a common problem I'm hearing and reading in the internet with the Ford/ Mercury Mountaineer the manufactory does not want to accept responsibility with this problem . . . . . This is clear a recall issue that needs to be addressed before someone gets killed on the highway by getting rammed by a semi-truck which it almost happened to me !!!! a multi-million dollar law suit is in order if they do not acknowledge and fix this problem.

11 Power Train problem of the 2007 Mercury Mountaineer

Failure Date: 02/14/2018

I had to replace the transmission and some other related parts in my vehicle and I was informed by a dealership that there was a "silent recall" on this transmission and that even though Ford motor company was aware of the issues as early as 2000 they continue to install them in vehicles. If you look online you will see quite a number of complaints on this transmission. I feel since Ford knowingly kept using these transmissions and was well aware of their possible failure when they reached 130,000 miles that they should be responsible for at least a portion of he costs if indeed, not all of the cost of replacement. What happens when a car company puts out a silent recall? do I have any rights? I have already sent a certified letter to Ford motor customer relations in dearborn, mi and I have a signed receipt that they accepted my letter but they have not bothered to contact me at all. What are my options and is this something you can help me with? the first time this transmission caused a problem was when we were in 5 pm traffic on a road with a speed limit of 55 miles an hour and the car just stopped leaving my family in the middle of a busy two lane road which was very dangerous. We were finally able to get the vehicle to the shoulder. I can forward my bills and copies of online conversations regarding the failure of these transmissions.

Since then I have spent over $1500. 00 in cost for repairs on this vehicle, beginning with I had to get the oil changed the same day that I bought the vehicle because the change oil required light came on as soon as I exited the expressway, I almost got into a serious accident on the expressway in route from the car dealership because a motorist tried to cut me off and that is when I discovered that the horn was not working. The next day the power door locks stopped working and things just has went down hill since then, the vehicle is in the shop right now as I'm typing this, I have not driven the vehicle anywhere other than back and forth to repair shops. I filed a complaint with the bbb but nothing was done about the complaint because the business responded saying the vehicle was used and I rejected the response and then received an email from the bbb saying that the case was closed. This vehicle was a lemon with a lot of issues and none of those issues were disclosed to me when I purchased the vehicle.

20 Power Train problem of the 2002 Mercury Mountaineer

Failure Date: 01/08/2015

While driving the "od" light started flashing and the vehicle would not shift from 2nd to third gear. It would just rev up. If you let off the gas it would usually shift into 3rd gear. I was going to try to check the fluid but couldn't find the dipstick. I checked the manual and found out there is none. When I checked online for help I found all the other complaints that were exactly like mine. It is very disappointing that Ford will not issue a recall on this obviously poorly designed transmission. This is a very expensive part for an owner to replace and is a safety issue as you could lose the ability to accelerate at a critical moment. With as many complaints as I am seeing online there should definitely be a recall. I hope it doesn't take somebody getting hurt or killed for action to be taken.

Failure Date: 10/06/2012

I got into my Mountaineer and notice a familiar rumble. My wheel bearins went bad again! I will be replacing these for the 4th time now. This is on top of having to have the transmission rebuilt to the tune of $3700. I love to drive this car but it constantly needs repairs and the repairs need repairs. I can not afford a new car but I can't keep fixing this one!!! I have also had to replace the intake manifold only to find out Ford had a fly by night law suit and never notified people to have there intakes checked so that was another $300 just for the part. I think Ford should help us out that helped them out.

Failure Date: 10/02/2012

I pulled into a parking lot and had the engine running while it was still in drive. I had my foot on the brake pedal and was looking through the center console to find my phone. After finding my phone, I shut the vehicle off and pulled the key out of the ignition. I returned to the vehicle roughly 45 minutes later to find that I had left the vehicle in drive and it had allowed me to shut the engine off and remove the key from the ignition while it was still in drive. Luckily, the parking lot was level and the vehicle did not roll away. Ever since that day, the vehicle will allow me to remove the key from the ignition, regardless of what position the shift lever is, as long as the engine is turned off.

34 Power Train problem of the 2002 Mercury Mountaineer

Failure Date: 05/01/2012

I, as so many others, have a failing transmission in my 2002 Mercury Mountaineer. From 2nd to 3rd gear it refuses to shift properly and when it does it is extremely hard. Others have experienced this condition while the vehicle was still under warranty and it is my belief that Ford realizes that the transmission is defective but refuses to do a recall. I was almost rear ended because the vehicle lost its forward momentum between the shifts. I feel as if this is a dangerous situation and it should be addressed.
