Just wish the transmission had a dip stick so I could check the fluid level myself instead of going to a dealership to get it checked

Mountaineer Premere V6

  • Automatic transmission
  • 99,625 miles

I called the Ford Consumer line and they told me to give my receipts to a Registered Ford dealer to see if they can do anything. I did what they said and before I was done talking they said I would not get any compensation from Ford on issue but he would check anyway. He called back a couple days later to let me know they would not do anything for me. He stated that he would make me a good deal when I am ready to make a purchase. I don't think he understood that why would I buy another Ford type vehicle if they were not going to compensate me with this one other than giving me a deal on another one that anyone could get!!!!!!!!!!!!!

Mountaineer ES 4.0L

  • Automatic transmission
  • 36,000 miles


Back in (I think) 2006 Ford issued a recall on the 2004 mountaineer. Somehow the wrong transmission fluid was put into the transmissions. I took truck in, they said they drained all the fluid out and replaced it with the correct fluid. About a year or so after that, the truck started to jerk. Took it back to mercury (was still under warranty) they said they could find no problem. I explained to them that it doesn't happen every time. Said there was nothing they could do because it didn't happen while they were testing it. As time went by, the same situation kept happening, today, more often. One time it happened, it jerked so hard, it actually move about 5 ft. back. That really scared me, but it never jerked that hard since. I tried to check the transmission fluid, but there is no dip stick.

I also have that craked line on the tailgate, plus it's craked around the emblem on the tailgate. I thought that someone must have tried to break into my truck until I saw 2 other mountaineers with the same cracks. A friend of mine mother has the same problem and some other and she also own a 2004 mountaineer.

The oil change light came on, I got an oil change, the light came back on the next day. I've had to have new pistons (might be called something else) put on for $354, replaced headlights. My truck is almost 7 years old and doesn't have 60,000 miles on it. I should not be having major problems like these. I bought a Toyota corolla in 1991. That car had 90,000 miles on it when I started having problems with it, and I never had transmission trouble.

Why did Ford/Mercury stop making mountaineers for several years. I'm sure it was because they knew they made lemons, and it took time for them to make a hopefully better mountaineer. Ford Lincoln Mercury have no shame for ripping off millions of customers. They should be made to pay. I will never purchase another Ford product. I I also plan to write a compliant to every consumer right group I can find. I paid a lot of money for my SUV, I want what I thought I was paying for, a good low maintenance vehicle, not lemons.

Mountaineer V6

  • Automatic transmission
  • 94,000 miles

I bought my mercury mountaineer new in 2004, I started noticing problems with the transmission sometimes banging in to gear and rough going into reverse at about 50,000 miles, it would only happen once in a while, it never really got worse until now at 94,000 miles it constantly slips out of gear and bangs into gear. My local service shop said i need a new transmission. Last time i buy a Ford.

Mountaineer AWD V8

  • Automatic transmission
  • 50,000 miles

My 2004 Mercury Mountaineer with less than 50,000 miles on it lurked anytime it was put into Reverse or changed gears. Ford denied that there has been any problems with their SUV transmissions even though I've read numerous complaints on the Internet. They only offered to fix my transmission for a cost of $3800.00. I decided to take my car to a transmissions specialist to save money and ended up spending $3000.00 on a rebuild transmission. I will never buy FORD products again.

Mountaineer 4.0L V6

  • Automatic transmission
  • 42,500 miles

I bought my 04 Mercury Mountaineer used w 42500 mi. We noticed the delay from shifting from park to reverse soon after our purchase. I hesitated to have the dealership check it out because it was my first Mountaineer/Explorer I've ever owned and though it was normal. When I found out that there is no transmission dip stick to check the fluid (burnt/low), I decided to have the dealership check it out before my very limited warranty (250 deductible, 50/50) was up. They could not duplicate the problem, however I complained enough get the solenoid replaced under warranty (along with the 2 rear U-joints that needed replaced) for 600.00. I check another ford dealer for price on solenoid, U-joints and labor without warranty and it was 1200.00..Check out all the complaints regarding the 04 Ford Explorer transmission, same setup I believe as the Mountaineer.
