The A/C drain tube leaks and causes water to pool up on the driver's side floorboard underneath the carpeting. I have had the vehicle looked at two times and all they can do is blow the tube out, which only temporarily fixes the problem. It is recommended to have the dash removed in order to get to the box where the debris is located to repair the seal. I don't have hundreds of dollars to have this done, nor can I do without my vehicle for several days! this should be made a recall because it becomes not only a safety hazard, but also a health hazard. The water makes the floorboard wet, causes the windows to fog up on the inside and causes the flooring under the carpeting to possibly become corroded. Plus, it causes mold to grow which makes my allergies flair up. So, Mitsubishi if you read this, please consider recalling all Endeavors to fix this problem!!

Bought this 2004 Mitsubishi Endeavor used with 64K miles in January. Started using the air this summer and noticed driver's side floor is soaking wet after each use. Found online that multiple people are having this same issue. Called the dealership and they confirmed that Mitsubishi is aware of it and have put together a fix between $220-$350 but there is no re-call. I was told the problem is a failed seal in the A/C unit. Also, had to have the egr sensor replaced twice. Called Mitsubishi and they said nothing they can do because the car is out of warranty. It ran $400-$500 each time at the dealership.

After driving on a long trip, found the driver's side floor carpet and mat soaked with water. Ac drain tube is blocked causing mold and odor. The drain tube is too short and located inside the firewall and needs to be lengthened out of the firewall (per Mitsubishi tsb-11-55-003). The flooring continues to be soaked with water even when the ac is not in operation. This is an unsafe condition due to the stepping on the wet floor mat and causing the break pedal and gas pedal to become wet, causing your foot to slip off the pedals when wet. Not to mention the breathing in the mold caused by the wetness.

Blown engine on a well maintained, single owner 2004 Mitsubishi Endeavor with under 70,000 miles. At 55mph and without any prior warning (e.g. no warning lights on dash or changes in dashboard gauges), the car made an extremely loud noise (almost high revving like), became difficult to steer and rapidly was losing power. The battery light came on followed by the "service engine soon" and while the car would turn over and start the noise became louder and the car would stall out. After being towed to the garage, the car would not start at all and I was informed that the engine was blown. My mechanic also noticed that my driver side floor mat was soaked which I had actually noticed 2 weeks prior when was cleaning my car but had thought that I had accidentally gotten it wet during the washing process. Given that we have had no rain since then nor had I washed the car since 2 weeks prior, it was clear that this was not an issue of getting it wet. My mechanic then said that of the 6 2004/2005 Endeavors that he has repaired in the past year, he had seen the same issue and while some resolved with the unblocking of some line that had to do with the ac he also noted that the others required a much more extensive and costly repair due to the heating element which could cause the engine issue. He also noted that each of the Endeavors with the soaked driver side mat issue had also lost their radios. Ironically my radio had just gone out the week prior (it comes on as if it is working but no sound out of the speakers) & I had made an appt with Mitsubishi to resolve. The more I read online the more I see the same issues that I and my mechanic have noted therefore it seems like there is clearly a very costly pattern of problems with this particular line/year of mits vehicles. Given that I bought my car new in Jan 2005 and serviced it accordingly, this issue seems suspect.

Due to a faulty a.C. filter material, the air condition drain duct is obstructed. The faulty material breaks down and hinders the ability of the condensation to drain outside of the SUV. The water has no where to go and leaks into the interior floor board and saturates the carpet and interior components of the car. The water also becomes trapped in a pocket or area of the floorboard and cant drain outside. This problem results in a mold developing and can or will be harmful when exposed to prolong periods! we have had the drain line cleaned out on three separate occasions, at our own expense and the issue keeps recurring? the repair shop states the deteriorated filter material continues to break apart and become lodged in the drain line. Mitsubishi has yet to have a recall on this issue and their remedy is to bring it in to the dealership for a repair charge that is expensive, unaffordable and unreasonable! we are having breathing difficulties due to the obnoxious and possibly toxic mold smell. We need the car for transportation back and forth to our jobs and have no choice as we need to pay our bills! surely if this was a minor repair cost we would have corrected it due to the possibly harmful nature, however the repair cost is unaffordable. Considering this is a possible safety issue, we would appreciate and feel it necessary to investigate this issue and have the manufacturer correct it. We are aware of the economic hardship that is effecting everyone and are concerned, however insurance and safety of occupants should be upheld above any circumstance! certain molds are proven to be harmful or fatal. Thank you

2004 Mitsubishi Endeavor. A/C drain fails to properly drain causing water to drain onto the drivers side floor. This also occurred over two months during which I wasn't using the A/C so it may also be related to rain water or other condensation. Mitsubishi knows this is a problem but will not fix it. The dealer quoted me $900 to fix.

I purchased a 2004 Mitsubishi Endeavor from dave smith motors in September, 2005. It has been in the shop for repairs 6 times. Once they replaced a falsely sealed front windshield, twice they repaired the heater core, and once they repaired the drive line. The 2 other visits were for initial inspection and estimate. Now it smells like burning electric wires and it is stalling while in motion. This car is unreliable and has been under repair for weeks! I am afraid to drive it because I never know when it is going to break down.
