Ford Explorer Mercury Mountaineer 2006 and newer



  • sacmtnrsacmtnr Posts: 15
    Just returned from a trip to Florida from Northern Virginia. I was curious what the mileage for the entire trip might be so I didn't reset the mileage tracker until we returned home. The trip covered approximately 1900 miles. About 1400 of these were highway, with the rest being just general sight seeing and quite a bit of beach driving (aprox. 60 miles). Also sat in one highway backup on the way home where we only traveled about 5 miles in 2 hours. The total average mileage was 20.8. I was actually very surprised it was that high. I would have expected that for just the highway part of the trip. Will also mention that the vehicle always had 4 people in it.

    A note on the transmission issues with the 6 speed, it's been about a month since I had the latest flash update (from late November/ early December actually) done and it still seems to be shifting slightly better. Like I said in an earlier post, it's not perfect but the latest update did seem to make it a little better so might be worth a try for those of you that haven't done it yet.

    Good report. Thanks for the update.

    While the tranny issues, minor and isolated as they seem to be, make be glad we went with the V6 in our '06 Explorer I think we'll get the V8 if we get a Mountaineer next year when the leas is up. Our best highway mileage came last Summer on a trip from Pittsburgh to the OBX where we averaged just under 22 mpg. Seeing that the V8 gets similar mileage it would be worth the extra $$ just to have the extra power. The hills around here make the V8 slightly strained at times.

    There is definitely a big difference from the V6 to the V8. A friend of mine has an 06 Explorer with the V6 and when I drove that it was easy to see that it wouldn't take much to put a strain on it. Short of trying to pull your house down the street, there is not much that would stress out the V8. I have pulled an enclosed motorcycle trailer (800lb motorcycle inside) and the only way you can tell it's back there is because you can't see out of the rearview mirror. Power and passing speed is very impressive. In my opinion V8 is the only choice.
  • I own a 2006 V6 Mountaineer with 43000 miles on it. Since my first oil change at 3,000 miles the car has had what I call a "flutter" that lasts from about 30 mph to 50 mph whenever I'm accelerating. It sounds similar to the sound you get when you put a playing card in the spoke of a bicycle tire. I've complained about it to the dealer every 3000 miles when I take the car in for oil changes but they haven't been able to figure out the problem.

    Has anyone else had this problem? Were you able to get it fixed?

    I just returned from a trip from Chicago to Memphis and back and I did average slightly under 21 mpg on the highway. I thought this was good for the V8.

    I have pulled a 3100 lbs trailer with this Mountaineer and found the V8 more than capable of handling that weight.

    As for the transmission, after the November flash it has worked better, but not perfect. Too bad this problem has left such a sour note with me towards Ford Motor Company's ability to recognize and admit there is a problem and satisfy their loyal customers.

    I actually did drive my father-in-law's '06 EB V8 up and down a couple of side streets once. The power difference was noticeable but his gas mileage was pretty poor compared to what others get. I've rode with him so I'm 100% sure that discrepancy was due to his driving style. He drives like my wife, who is the primary driver of our family hauler, so that kind of worries me. She'll be getting the minimum EPA rating or less no doubt.
  • Hi, Did you ever get your problem with your Explorer resolved? I have an 06 Explorer that hesitates and lunges too. No one seems to know how to fix it and we are trying a different dealership to see if their mechanics are any better.

    My Explorer hesitates, lunges and shakes. It happens sporadically, however the mechanics have acknowledged the problem and tried to fix it via computer codes and replacement of the throttle body...twice within the warranty of the part.

    Please let me know what steps you took to get your car fixed or if it wasn't fixable. My car has been back numerous times for the same issue. The diagnosis is always the same codes or not having the correct computer codes. If anyone else has had the same issues, please contact me.
  • Yes I did get the problem resolved for now (feel like I should knock on wood) from the dealership. First time was to reflash the codes. Second time a new TSB came out and the dealership replaced the valve body with a new one that had some changes made to it along with replacing the filter and fluid. The TSB also contained another, newer, code flash that seemed to make the difference. Before I left the dealership the mechanic did advise me that he removed all the stored memory from the adaptive learning module. He said it may act up again briefly but his suggestion was to drive it about 50 miles (round trip to a small town near me and back) and that should reset everything.

    I did as he advised and have not had any problems since ro maybe I should say so far. As a result of this problem I purchased an extended warranty just in case and I've never had to do that before.

    Everything the dealership did was under warranty and didn't cost me a dime. Guess I was lucky that the dealer was willing to go the extra mile and the service guy told me up front the first time I was in that they had been seeing this type of problem frequently. He said Ford was supposed to be working on the problem and a new TSB was coming out along with a redesigned valve body (the one I mentioned earlier).

    Good Luck trying to get it resolved.
  • hi i own 2006 mercury mountaineer awd v8 when i come to stop my transmission kicks hard in to gear like i have been hit from behind does anyone have any fixes for this
  • Does anyone know of any extension towing mirrors I can get for my 06 Mountaineer?
  • how many people have had the problem with the od light coming on, the message transmission light comes on, transmission slips, up shifts, then it just started slipping, i had only 88,000+ miles on vehicle, transmission was checked and had to be rebuilt, there was a a bad design somewhere, when a piece of equipment wont even last 100,000 miles, it just gives you doubts about ford products. all maintenance work was kept up through ford dealership.

    What engine and transmission does the Mountaineer have? It is hard for me to have doubts about (all?) Ford products because your (one) Mountaineer has a problem. I've had Ford products that gave me wonderful service and some that weren't so great, but I never thought that I could make a blanket statement about all Ford products.
  • I'm looking at an '07 Ford Explorer (4WD) in the V8 & wondered what are some
    of the problems associated with this years model,...especially from current owner's
    out there. My impressions is that the '06 experienced more reliability issues than
    the '07 Explorer but I don't have an factual data or knowledge if that's true, especially
    involving the transmission. Any comments regarding reliability, what to look out for
    and if the '07 Explorer SUV (4WD) V8 is a good vehicle to pursue in the "used"
    marketplace? Anyone recently purchased one, in the Eddie Bauer Trim, and
    what was the final deal price?

    There are many nice things that I like about the 06 Mountaineer, but I would not buy another used or new. The transmission in the 06 is horrible. From nearly day one through today it slips and hesitates at slow speeds. It takes a second or more to engage which can be dangerous if you need sudden acceleration. the transmission also suffered an astounding problem of clunking when slowing down to a stop. It felt as if the vehicle was struck from behind. After over a year Ford came out with a fix that has actually limited this problem. My mountaineer still will clunk on a rare occasion, but luckily much more minor then before. Many other aspects of this vehicle are exceptional. If deciding to buy be sure the transmission has had the latest fix for the transmission. I would test drive by slowing down to nearly a stop and then re-applying aggressively the accelerator to see if the transmission lags and doesn't engage quickly and smoothly. There should also be no feeling of a jerk or clunk. Good luck.

    Like you said there is a software fix for this from Ford. Most who have had it done seem to think it did the trick.

    There's a good explanation of the problem by a Ford engineer somewhere on a Ford forum I frequent. It's not a problem with the transmission exactly but rather a side-effect of the new tranny design. Something about it not using a clutch pack or something like that. It wasn't intended and is, IIRC, inherent to the design. I believe the software update changes the shfting algorithm enough to smooth that "bump" feeling which is supposedly not harmful to the tranny at all.

    I have an '06 V6 with the 5-speed tranny and it's as smooth as butter so far. However the V8 does get slightly better FE and has a lot more power if you can live with the "bump" or have it fixed and live without it.

    My 2006 Explorer EB V8 with rear wheel drive has 52,000 miles on it and has been a wonderful vehicle. It is a work vehicle, and has no third row seat and no factory subwoofer, thus making the rear storage area wide enough for my 15' Little Giant ladder and various tools and supplies used for inspecting and testing for toxic / hazardous materials. I installed an pioneer AVIC-Z1 navigation and sound system, with XM, XM Navtraffic, Bluetooth for wireless cell phone use, and a rear view camera, plus four speakers, just after I bought it.

    When I destroyed one of the factory tires, I replaced the factory tires with the excellent Pirelli Scorpion STRa tires, a substantial improvement.

    All of the negative comments regarding the transmission really seem to eb comments regarding specific dealer mechanics. My 2006 EB V8 had a problem with a rough downshift to first when coming to a stop, but it did not bother me much. I only had it fixed just before the warrantly expired to take advantage of the free service. The mechanic at Santa Margarita ford kept it for several days, and took it apart twice to get it right.

    I lock and unlock the doors many times on a typical day, so was not surprised when the power lock on the driver's door failed last week. I removed the door latch on Saturday, dismantled it Sunday, found a small gear worn at one end, flipped the gear on its shaft, and lubricated the mechanism. It should bb good for another 50,000 miles..

    That's the one everyone is talking about. I'm not sure why your dealer was taking the tranny apart because there is a software fix for it. They should be able to take care of it in less than an hour.
  • Have to agree with Baggs.

    I had the same problem and the fix was two stage. First time a new code was released to flash the system but I still had problems. Second time (several weeks later) another new code was released along with replacing something called a Valve Body that evidently had a new design.
    After the second trip the mechanic told me he cleaned out all the adaptive learning memory and suggested I drive it normally for 50 miles (short trip down the highway) and give it a few miles to readjust. First five miles it had some mild shift problems then it seemed to adjust and have not had any problems since.
    Lucky for me this was all under warranty however I did buy an extended warranty just in case.

    My sister has an '04 Explorer XLT and the exterior panel (plastic, I think) located between the rear hach glass and the license plate recently cacked into two pieces! Since that happened, I've spotted at least four other Explorers with the same broken I'm guessing this isn't an isolate incident?

    Does anyone else know about this issue or perhaps you've experienced the same problem? I'd love to find out that Ford will replace it (even though the warranty is long gone), but I'm wondering if it was a defective part altogether that they should be paying to replace?

    Any advice will be appreciated!

    I've read about your cracked hatch problem before. IIRC, Ford does not fix that under warranty unfortunately. Others have stated they had to pay for it out of pocket. That's not to say you can't try if you still have some kind of warranty working for you though. I've only read about it a few times.
