    We are experiencing a noise when the vehicle has become warm, and are driving around 70 mph. It sounds like a whining sound, almost like a balloon losing air slowly. It also seems to only take place when applying gas. We took it in to a mechanic but they could not find any problem. Has anybody else had this problem? What is it? Not sure if related- but we have had the "Service Engine Soon" light come one- and I checked it with my handy code reader and it stated "Too Lean." Seen this a couple of times; the light goes away, but have seen this on longer trips where the vehicle is driven for longer periods of time. Timing belt? Fuel pump? Water pump? Belt? Drive train? This one has me totally stumped.

    Also- the power window on the driver's side will not open the rear right window.. but it will close it...
    One other item- the external rear light seems to crack all the time- I think it has something to do with the position of the rear window washer sprayer (comes through the light) and sunlight- the plastic expands and it cracks. We have about 90K miles on it- but have had a great experience overall. Would like to fix whatver the noise is because it does worry us (we use this car often and have 2 small kids).
    I'm guessing most owners of this SUV have or are having these problems...
    Any Mitsubishi mechanics reading this??? Please help!

    My car is the same as you all, it has lost its clear coat and and looks terrible. I am amazed that you all have had the same problems because I thought that it was something that I didn't do, or did. Like when it went to Vermont for Christmas and it was 18 below at night.
  • I'm also having this issue in my 2006 Endeavor. I thought I would try running the new hose through to the engine compartment before drilling a hole through the floorboard. How is that solution holding up?

    (Can you provide me with pictures/detail on how you sealed the hose on the inside of the evaporator box?)

    I just had the same problem with my 2004 Endeavor. The mechanic said it was the torque converter..that it sometimes gets a coating or "varnish" formed on it. He corrected it by changing the transmission fluid..( if it had just been changed, he wouldn't have done that) and putting in an additive that Ford makes since they had lots of problems with this happening at some point. He said it might take a few days for the shuddering to disappear but I drove away and never felt it again. That was a month ago.
  • For the record, after 1.5 days of trial and error I was finally able to get the new hose through and sealed on the inside and all is good. I had a really hard time getting a seal around the hose to block off water from the old route and force it through the new hose. But finally found the right size hose and used the tapered tip from a silicone adhesive tube to flare it out, then cut the tip at the right length and pushed it all into the evaporator pan drain with a little plumbers goop to help seal it. Works like a charm! Whew. Glad to get this one behind me.
  • Driver side rear quarter panel. Air pressures caused by chassis movement on uneven road surfaces causes it to flap and tap sounding like a rattle. Only way to get rid of this problem is to remove the Endeavor's rear cargo trim on the drivers side which (unfortunately) is one-piece so you must remove the entire trim. Thankfully, it's the side away from the subwoofer (the subwoofer side is 3x harder to remove with many more small pieces to deal with). Driver's side cargo wall trim only consists of the obvious screws (and I believe one bolt) that you see, and about 8 clips that hold it down.
  • 2004 XLS Endeavor has begun opening the back end of the sunroof (which you can't do with the switch) on its own. Sounds crazy I know, but it appears as though there is some kind of electrical glitch that is occurring that causes the sunroof to move forward enough to raise the back end. Of course it happened again today while in the store and it began raining. I already had some of the same roof leaking problems when going through the car wash, but this one is new. No one is messing with the switch and the car is garage kept. Any one have problems with this...yet? Thanks

    With the help of the other forums, I threaded a coat hanger through the drilled hole in the HVAC case and out to the engine compartment. I then put a 3/8 inch copper tube (about 4 inches long) spread some adhesive on the end and pushed it into the drain line using the coat hanger as a guide.
    Let the adhesive dry before running your AC.
    The copper tube should be bent a bit to make the turn past the fire wall and also install a 90 degree fitting to guide the water down. Keep the tube higher at the point where it is inserted into the drain so no water will run up the side of the tube and back inside.

    I did this about 5 months ago and it still works fine.

    I have a 2004 Endeavor, and it developed a noise which sounds like a tensioner pulley. However after changing it the noise is still there. The interesting thing is that the noise is only there for about 10 minutes after you start the engine in the morning and then the noise is gone.

    That's great to hear and with cooper tubing.

    I'm still holding fine with my plastic deal and the o-rings. Since the humidity here i always around 98-100% it makes some nice puddles. ;)
  • My 04 Mitsubishi Endeavor looks like it should be in a junk yard. I bought it new, it has 137,000 miles and has been peeling for the past 2 yrs. I called Mitsubishi about it and they had me take it to one of their dealerships with a body shop. They said if their body shop said it was a defect they would see what they could do to fix the issue. So last fall I took it there and they said in writing it was definitely a defect, too thin a clear coat and it was maybe only worth a 1/4 of it's value due to the paint and how it looks. They sent their report in and I've called Mitsubishi and can't get anyone to answer my calls now. Anyone else gone through this and had any success?
  • Thanks for the great detail. Just drilled my hole in evap drain tonight and had a ton of water come out. Will install bypass hose tomorrow.

    Have a 2007 AWD, so not sure of best place to drill hole in floorboard. Looking for suggestions.

  • It's behind the glove box which is removed by taking out 4 screws.
  • I went for the transmission hump. So not really the floorboard/floorpan. Since I only had a 2WD it seemed to make sense as it was wide open.
  • I had that problem.I solved it making 2 small "surco" (I dont know the translation) on the bolt and put a O-ring on each one.
  • Just fixed a 03 Endeavor that had this problem. The exhaust flange behind bank 2 converter had broke where the final converter and rest of the exhaust system connects to. I was able to remove the bolts and place the flange back in place and weld it. sounds much better now.
