2003 Mercury Mountaineer recalls I have had to change the intake manifold, ignition coils, I'm having a gas smells now, transmission thumps hard when going into first gear, sounds like my rear end is about to fall out, my front seat is electric and doesn't move, the o/d light comes on, check engine light on, brake light on, I keep trying to fix everything the more I fix the more problems that come up, I have check the recall list for 2003 Mercury Mountaineer recall on transmission and also called the Ford CO they said there is nothing. The problem is getting worst and afraid I will be on the highway with my grandchildren when it breaks. I've had transmission level checked said it was fine. Getting ready to do a complete tune-up on it to see if that will help with the smell of gas and make it run better. It idles high. It's worst when I'm on the highway.

While driving my vehicle the o/d light starts flashing very fast. I can hear the vehicle revving as I am pressing on the gas. All of a sudden a hard pop and then the vehicle starts to accelerate. I try to continue home and the vehicle gets to around 30 mph and does it again, as time goes on (same drive) it gets harder to shift into gear around 20 mph and stays at that speed. Vehicle is a 2002 Mercury Mountaineer with 150,000 miles.

Ford has a TSB on their website for the problems I am having with my vehicle. I contacted tyem and I was told that I have to pay for the repairs. What I do not understand is if there are sooo many complaint from consumers on this vehicle for the same issues is that not the responsibility of the manufacture being it considered a defective product? I have to children and this is of extreme concern to me that these issues on my car can cause an accident. -back trunk door is cracked down the latch. -the car doesn't shift correctly and tires seem loose -the overdrive light is blinking all the time and the transmission is signaling. . I have found so many websites with complaints about the same issues on 2003-2004 Mercury Mountaineers.

The contact owns a 2002 Mercury Mountaineer. The contact stated the vehicle had a very hard shift for a few months. While driving the transmission failed and the overdrive light came on prior to the failure. The vehicle was taken to the dealer several times since it was purchased and was always told that nothing was wrong with the transmission. The dealer recently stated there was a blow hole at the bottom of the transmission and the hole expanded which caused the failure. The dealer told the contact there was a repair kit that could be used, but not until the transmission failed completely. The vehicle was not repaired. The failure mileage was unknown, but the current mileage was 75,000.

The problem was not noticeable at first. The SUV felt heavy when accelerating, it will jerk every now and then it was like this for a period of two days then the o/d light flashed rapidly and on the message center it displayed check transmission< the transmission constantly slips on every gear it revs without accelerating and when unexpected it catches itself and lunges jerks forward. It also makes a loud noise whenever the transmission shifts gears. This is everytime the vehicle is in use. I have no other means of transportaion . I took it to get diagnostics checked and they told me the transmission was faulty that there had been hundreds of complaints in my area dealing with the same make and model and year. I have not tried to correct the faulty tranny . I believe Ford should consider the safety of it customers /consumers and should have a nationwide recall to repair such faulty transmission. I have been more close to crashing this year than all my years of driving. This faulty transmisssion is dangerous.

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!.

I own a 2002 Mercury Mountaineer 4. 6l awd. After buying this car I had heard about how big of a lemon the transmissions are, and on January 27th I found this out for myself. First my car began shifting very harshly. Then my o/d off light began flashing, check engine light came on, and check transmission lcd came on. I lost third gear on the middle of the highway and had to drive 9 miles home going only 25 mph. Then I found out that it is going to cost $2500+ to fix the problem. Unfortunately I'm a single mother and full-time student, so my car is just going to sit for a few months until I can afford to fix it. Ford should be held accountable for this problem. I have heard far too many complaints and no one has done anything about it .

O/d light blinks and transmission shifts hard or misses shifts. Feels like tranny might be about to go. . . Started about a year ago but went away after changing tranny fluid. Now it is back, issue is worse, and seems like it is here to stay.

2000 Mercury Mountaineer transmission failure vehicle has only 64,000 miles, transmission has been power flushed by our local Ford dealership with no correction, we were told the problem was shift flare, with the o/d light flashing is common with all 5r55e transmissions with 4. 0l v6 engines. We were told it would be best to replace the transmission with a factory remanufactured unit, rather than try to repair the old transmission at a cost of $2500. 00 to $3000. 00 dollars. We are now to a point where we cannot drive the vehicle any great distance other than right around town. Assistance from Ford would be greatly appreciated this vehicle is the fourth Ford product we have owned, we now have doubts about our 2005 f150 4x4 supercrew we use to pull our 26' travel trailer approx 4860lbs. Our vehicle is in wonderful condition and we do not want to get rid of it, the manufacture needs to step up and help all the loyal Ford owners that have believed in there products for many years.

The transmission on my 2002 Mercury Mountaineer. The o/d light is flashing, and seems trans is slipping even worse. I have had it to the dealership many times since I bought it new, and they never could find the problem. Now it has been out of warranty for quiet some time and has became a huge problem. I looked on the internet and noticed a ton of complaints on this exact issue and was hoping it would be ground for a recall.

On Dec. 19, 2008, the o/d light began to flash and then on Dec. 26th the service engine soon light came on. As I was driving the car began to rev up when I was not mashing the gas. I have not driven it since. I called the Ford dealership and was told to do a diagnostic test on it, it would cost $98 per issue. I searched the issue online and found that many people have complained about this and have paid thousands of dollars to have it fixed. I would like to know if this is a recallable issue due to the about of complaints? I just spent $300 having the door ajar sensor fixed, something that others have also complained about.

After reading other complaints regarding 2002 Mountaineers and explorers, I can hardly type I am so frustrated. The number of power train complaints for this year, make and model are astounding. The transmission in my 2002 Mountaineer (aka money sucker) needs to be replaced. The car is currently being fixed at the Ford dealer for $3500. The car has always had a funny shutter when shifting from 2nd to 3rd as well as hesitation when dropping into reverse and drive. While driving in icy conditions yesterday my wife thought her tires were spinning when she was trying to proceed at a stop light. She thankfully avoided being rear ended by a semi that was able to swerve onto the apron and avoid contact with her. She was able to limp the car to the side of the road where she then called me. After I arrived, I attempted to get the car to the Ford dealership where it could be diagnosed. However, the car would only reach 30mph and the rpm?s were at 4,000 to 5,000 at that speed. The overdrive light flashed and the check engine light came on. I parked it and removed the battery cables for 10 minutes to see if the computer would reset itself ? this did not help. In fact, the car would not even move in drive or reverse. Had the dealer pick it up to get it fixed. This car has 108,000 miles on it ? not exactly knew this is true, but it sounds like I was one of the lucky ones to get that many miles out of it ? from the reports I've read on the internet. Have also experienced and replaced front left bearings, rear left bearing and have the problem with the steering that many have reported on this vehicle (binding, tension, can?t make full turns, popping sounds).

Traveling I-95 n between baltimore,MD and wilmington DE when transmission started slipping in 2002 merc mtnr. Transmission slipping when shifting into 3rd gear at toll both. Pulled off hwy at rest stop but did not turn off engine. Pulled back onto hwy, accelerated and check transmission indicator came on. O/d light began flashing.

Had just replaced left rear wheel bearing and rear parking brakes week prior for $650. Vehicle had 75k miles.

The gears began making a whining and clicking noise as shifting occured at slower speeds. We were on a highway for approximately 1 1/2 hours when the o/d off light started flashing and the transmission downshifted from 5 th gear to 4th the remainder of the way. The words "check transmission" came on the odometer screen.
