    Outlanderlsgeo I'm assuming your Outlander is a LS? Do you hear a noise (maybe from the tires) when you're turning at low speeds? Like in a parking lot.

    Just wondering if anyone else has heard this and if it might be the Yokohama tires on the LS.
  • checked mine out but didn't hear anything. i know i hear 1 clunk a couple of minutes after i started driving, after startup. which according to a TSB i read(sorry couldn't add a link. forgot where i saw it), is normal as long as it happens only once 'coz its the ABS checking itslef. But if it happens more than once i know th TSB fixes bearings on the Left and Right wheel which mostly affects 11/06 and 12/06 builds but not all. Have it diagnosed at the dealer. I will be changing my yokohamas to winter tires nextweek

    Car was at the dealer today I had them check out the noise. They said it was normal tire noise. With 4 1/2 years of warranty left if it is something else I have plenty of time to have it taken care of.

    Mine was built in January and I've never heard a clunk in the front end.
  • Mine was uilt January too, i haven't heard this noise or maybe i should listen to it more closely. this happens at low speeds? let me check mine again..
  • I think they fixed the clunk early, mine is a Dec 06 build and it has never clunked.

    The throttle TSB is great, the more I drive it the more I notice how much better it is now.
  • Biscuit! Hi my outlander was built october '06 Do I have to do the throttle TSB's?

    Thanks a lot!

    Yes. It applies to ALL 07 Outlanders built before July 07.

  • I had the throttle lag as well. I printed off the 2 tsb's and took them into the dealership. They fixed everything in the vehicle runs MUCH more smoothly. Thanks to whoever posted the tsb's. :)
  • This message is directed to owners of an '07 Outlander.

    My Mom purchased one last spring. She took it in for the 3K maintenance last week and they found that her transmission was leaking. It was repaired, supposedly, but when she returned to the dealer a week later as informed, the tranny was still leaking.

    The dealer made several calls and she was told to leave the vehicle at the dealer. She was given a loaner and told that they would be replacing the tranny. Japan asked that hers be returned to the engineers in Japan to see what was causing the leak.

    Anybody have this, or other, tranny-related issues?

    Amen to the TSBs. I had them done and the tech was cautious about what I should expect since the throttle is "fly by wire", and he expected I'll always find it "different", but
    I'm very pleased with the results. I told my wife to forget
    what I told her to do before if she were to drive my outlander since it behaves normally now .The pedal is much more linear from stop and no "sags" when rolling along.
  • I am so glad to read this from you. Many thanks. Can you also post the 2nd tsb (07-23-006). I can only print the 1st tsb.
  • Thanks for the tsb info. I bought a 2007 Outlander this September and noticed the throttle lag the second day of use. Probably didn't notice it earlier because i was used to my Ford Taurus which had a much stiffer gas pedal. Took it back to the dealer who ran diagnostics, found nothing wrong. I'm not sure when my car was built but the VIN does not fall under those listed on the bulletin; ie 7U instead of 7Z, yet I am still noticing this problem. Can i still use this bulletin to take to my dealer? Other than this problem, I love the car. :surprise:

    here is the link to the posted TSBs (if you have an account)

    My car was built in March, so it applied.
  • I noticed the lag on my first test drive. Purchased mine in November and it also had the lag. I took the TSB to the dealer and they took care of it. No more lag. Thanks all who posted the TSB's.
  • I live in canada, and had my '07 outlander in to the dealership to get the throttle lag fixed. Since then I've noticed significantly worse fuel consumption. I called the dealership to tell them & they told me that since it had gooten colder, anyone who'd had the throttle lag fixed was having the same issue. I asked to be switched back to the old ecu/throttle program, saying I'd rather deal with the lag than lose 50-100 kms every tank of gas (yeah thats right!). They told me once the program was updated, it couldn't be fixed.

    can someone help! anyone esle experience this problem? any fixes? I'm about to call Mitsubishi Canada, hopefully they can offer some ideas.

    Is that displayed MPG or actual MPG you are talking about?

    I notice that I haven't approached the displayed 26 or 27 MPG on HWY since the change (now maybe 23 mpg) but it is colder as you say. The only true MPG is measuring by computing your own consumed gas vs miles. (unlike my wife's Malibu that is very close on the displayed average MPG). As others pointed out the
    display starts all over each time (my first few miles may say like 4 mpg, etc until
    enough miles are on it.) Mitsubishi should learn from others and change the way it works.

    Lately in the cold my mileage is about 21 mpg US (with the throttle lag change made) with combined local and HWY miles. Last fall (warmer and before the change) I think it was close to 23 MPG

    Hope this helps. for comparison (don't trust the display and make real measurements)
  • the avg is higher, but i base the claim on actual mileage recorded from tank-to-tank. I haven't changed my driving style at all, and I'm getting between 50-100kms less per tank of gas. I've gone through 5 full tanks since the TSB, and its happened consistently each time. I usually get between 475-550 depending on how much highway driving I've done. now I'm lucky to get 450kms out of a tank.... usually closer to 400kms.
  • I see this concern by madmax was never finalized...too bad as I have the exact same problem with the valves tapping at low rpm on a 2007 low mileage engine. I will be heading to the dealership soon to have them check it out. Probably will say it is normal or related to the cold weather. Has any one else had this problem and was it fixed? I know that there is no power loss and it is not a major problem, but with less than 2000 miles on a new vehicle, a quiet engine would be nice. I know our Outlander maintenance schedule includes a valve adjustment every 15k; perhaps I can get them to perform one early.

    I never saw anything about valve adjustment in the maintenance schedule, this would be pretty unusual for a new mainstream vehicle. I've noticed about a 2 MPG drop in mileage on the highway (from 25 to about 23) since the temperature dropped. It was about 10 degrees this morning.
