Failure of front differential mount carrier bushings failure leading to two transmission rebuilts,transfer case rebuild, and over $5000. 00 in repairs. Failure of carrier bushings would lead to front end locking up. Causing a jackhammer affect on the drivetrain of the vehicle. To close calls due to front end locking up. Accidents were avoided due to driver vigilance. Have pictures of bushings and what's left of the bushings.

Transmission seems to be failing or transfer case its really a big problem because when I drive onto the express way a rattling noise gets louder as I accelerate I feel conserned about my safety and my children plus other drivers they should recall for vehicle inspection I am very upset and scared.
The contact owns a 2004 Mercury Mountaineer. The contact stated that while attempting to change the wheel drive, the vehicle failed to utilize the forward wheel drive. In addition, the vehicle began exhibiting several failures simultaneously. The power steering assist failed, the gear shifter failed, and the transmission was causing the vehicle to jerk abnormally. Also, the power windows had become inoperable. The vehicle was taken to an independent mechanic for inspection. The contact was informed that the transfer case and transmission needed to be replaced. The additional failures were not diagnosed. The vehicle was not repaired. The manufacturer was notified of the incident. The approximate failure mileage was 83,000.
Transfer case defect causes steering difficulty on slow turns. Transmission issue reported to Ford in 2005 at 38,000 miles. Again at 51,000. I opted for an aamco transmission when Ford refused to cover. Now transfer case is making driving dangerous. Turning ability greatly reduced,.
I have a 2002 Mercury Mountaineer, I have had more problems on this car than are countable. The transmission has slowly been slipping since I bought the vehicle. I have had to replace the transfer case within the past two months, and now my check transmission light and od off light is on. Mechanics now say I need a new transmission. I have looked at numerous review on this make and model cars and all have transmission problems, and those who said they replaced the transmission, the problem recurred and it was a waste of money. I am just trying to figure out what to do these prices is getting very costly for a car that seems like cannot be repaired.
Rear back hatch cracked when purchased, promised to be fixed by dealership, but they never honored their promise. I have since seen several Mercury Mountaineers with the rear back hatch cracked as well, wondering why their wasn't a recall?? also transmission problems, already replaced transfer case and now power steering is leaking.

Bought used from a dealer 10-05 with 71328 miles. Checked out by mechanic. No problems w/ drive train, tranny, or suspension, except to change fluids in differentials (rear & front). Did this first week we owned it & water found in rear differential. 1st owner's records came with car. All services were done (no mention of problems). I serviced it every 2-3000 miles. On 4-27-06 the tranny flushed, & the rear differential & transfer case serviced. Mileage was 85857. 2 new tires put on front on 5-25-06 (flat tire). On way home (18 mi. Into 35 mi. Drive), front end started to fail. Couldn't find source of leaking fluid. Drive home. Next morning, tried to return to mechanic with car. Made it about 25 of the 35 miles to town before front end failed. Mechanic showed us the gears from the differential--the "teeth" were sheared completely off 1/3 of it--remaining teeth sheared down by at least 50%. Front differential was replaced, also 4 ball joints, seals for both shafts, brake pads (from differential fluid damage) were replaced. All 4 wheels had bearings repacked. 2 more tires bought. Within 1 week, began hearing noise again from drive train. Car back at mechanic on 6-20-06. The noise now from rear transfer case. It was flushed 2 times (fluid filled with fine metal fragments). The rear differential fluid also changed. Mechanic said 4-6 months until rear end failed. I've now lost the rear end--also have to replace all 4 sets of wheel bearings & replace all axles. Will re-assess front differential after rear is fixed. We've contacted Ford, no recalls for our car. They'll not make any repairs or reimburse for faulty equipment. I'm not original owner & warranty has expired. It doesn't qualify for state lemon law (mileage). There's at least 31 problems and 18 complaints on your website that I've had in the 1 year since I bought this car. This is a Ford issue. I just want to re-coup my $4000+ in repair costs & trade it off for a non-Ford SUV.
2004 Mercury Mountaineer purchased new sept. 2004. Transfer case was leaking while under warranty - all rear seals replaced. Started leaking again and vehicle was taken in for routine service @ 39,000 miles. Told large chunks of metal in transmission pan - transmission needs replaced. Vehicle no longer under warranty after 30,000 miles; Ford and dealer agreed to "share" some of the cost, $500 to owner. Believe leak is related to transmission problem that was not checked during original complaint when seals were replaced.
Had warped rotors within first 2,000 miles. Ford would only ground rotors but dealer replaced them at no charge. I have also experienced a loud, thumping noise when I am making a sharp turn to left or right at a very low speed. Also, often when putting car in reverse many times there is a large thump and vehicle appears to shift hard. Finally, when stopped on a steep hill, after removing foot from brake, vehicle rolls backwards many times.

Was driving and the SUV threw itself into 4 wheel drive low, causing rapid deceleration of vehicle. It was raining and it happened without warning. Ford has special service messages #508000 drive line trasfer case concerns. Contact has concerns about not being notified by manufacturer about problem. SUV is at dealer now and is still under warranty. Contact says is is very dangerous when this happens in traffic and rain.

Brakes failed seven times within 70,000 miles. An independent mechanic determined that the gem control module was the problem. When the gem control module malfunctioned, the brakes failed, and the 4-wheel drive didn't operate. Also, windshield wipers operated intermittently.
