Noticed I have water on drivers side floor from ac. Water pools and saturates the floor. Feet can get wet and slip off of brake or gas pedal. Also concern of mold growing in interior. Online search finds this is a common problem with this vehicle and no recall has been issued.

The roof rack has very flimsy paint and has been peeling for years. I contacted the dealership and was told it was not covered. I commute on the freeway and 90% of the Endeavors I see have paint peeling off their roof rack. I have kept this car in the garage for the last 8 out of 10 years. It has been protected from the elements and isn't driven much and still the roof rack looks awful! if I were looking to buy a new car and saw this, I certainly would not want a car with a paint problem.

Endeavor 6-cyl

On vac. While driving noticed the driver side floorboard soaked. Read on line several people have had this problem. Seems to be a defect from factory relating to the air conditioner. Was fixed in 2005 models. It can be dangerous as your shoe gets wet and can slip on the brake or gas pedal. I understand it is a $800 fix.Mitsubishi why haven't you done a recall on this??

Driver side floor stays sopping wet. I am assuming this is from the ac drain hose. Mechanics want $700-1000 to attempt to fix the problem, but say there are no guarantees as this has been an ongoing defect with the 2004 Endeavor. This raises several safety issues with main one being that feet are wet and slippery and likely to cause being unable to brake as needed due to foot slipping off pedal. Other safety concerns are in regards to the mold due to being unable to keep it dry. Please recall this and have it fixed as it should be. The consumer should not have to absorb this cost when it is a defect that should not have occurred.

Endeavor 6-cyl

  • miles
Noise of sloshing water in the trunk and water dripping onto the driver's floor; soaking wet carpet. Very bad odor! causing a sick feeling. Rear passenger windows failed; right and left approximately six months apart. The malfunction caused the windows to fall down into the door panel. Roaring noise coming from both front and rear wheels.

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!!

I noticed that the floor on the driver side of my Mitsubishi Endeavor 2004 was soaking wet and couldn't understand why since it was not raining. I noticed that the floor gets soaking wet whenever I use the car. I suspect that it might be the air conditioning leaking and it is. It get soaking wet and now I'm getting sick from the mildew. This has been going on for over 2yrs now. I cannot afford to get it fixed. This should of been a recall, I see loads of 2004 had this problem but it was corrected in 2005 Endeavors.

I noticed that the floor on the driver side of my Mitsubishi Endeavor 2004, bought in the same year, was soaking wet and couldn't understand why since it was not raining. My son noticed that the floor gets soaking wet whenever he or I use the car. I suspect that it might be the aircon leaking but didn't bring it to the mechanic because I was scared of the expense which I cannot afford now that we're on fixed income. Since June 2013, however, the leaking has noticeably increased, and my son used thick bath towels to dry the floor, but I noticed that the towels get soggy with whatever is leaking, but even a couple of thick bath towels not enough to dry the floor. Being concerned about it because it's starting to smell mildew inside my car, I told him to vacuum it, but it still remains wet and stinky that I'm scared for my health and that of my son as he has developed severe allergy, and I'd been sickly also, but I credit mine to old age, but cannot understand his since he didn't have it before. Being very concerned about the problem I decided to go online and found that many others are experiencing the same problem and health concerns. I cannot understand why Mitsubishi hasn't addressed the issue with a recall, or the vehicle owners not instituted a class action suit, which I will join since it's a vehicle defect that Mitsubishi corporation admits exists, yet has not issued a recall even though it's a critical safety and health issue affecting consumers.

My 2004 Mitsubishi Endeavor has some sort of problem that seems to be the same as others. The floorboards are soaking wet and are causing our feet to slip when pressing on the brake and gas pedals. The carpet is constantly covered in mold because of all the moisture and the smell is misty and sometimes unbearable. Have a young child with asthma and allergies and a newborn. I have not fixed the problem because there is a dealership, but wants to charge $1,000 to fix a design flaw. Mitsubishi motors has a technical service bulletin (tsb-09-55-002) to fix the problem by drilling into where the water accumulates and install a secondary drain.

I discovered the floor all wet on the driver side while I was driving. It has been wet for the past 1.5 months and since it's been getting hot I think it has to do with ac drainage issue. This is a big concern because this can cause my shoe to be wet and slip when I try to brake.

We noticed a lot of water on the drivers side floorboard after receiving the car back from receiving hail damage repair. We contacted the auto repairman assuming that the water was associated with the repair. We were told that it was not that the Mitsubishi Endeavor has a design defect with the heater core and ac drainage. A second mechanical opinion confirmed this. We vacuumed the car using a shop vac and documented 4 inches of water removed from the car on two seperate vacuuming sessions. A member of the family is allergic to mold and has found the resulting mold to be a health hazard. This is the only mode of transportation for the family and the quoted cost of repairs is in a range of $400-$900. The wet floor presents a potential for physical harm as it is extremely wet.

Like many, many reports the drivers side floor mat is saturated and pooled with water from the ac/HVAC system drainage failure. The manufacture has tsb's on on the issue with foam gasket replacement or initially drilling a hole cleaning it out and installing a rubber plug tsb-08-55-007. Now installation of a hose used for radiator overflow on an eclipse now being suggested no: Tsb-11-55-003. How is this not a design flaw and how is the mold and moisture issue not a safety concern. The internal cab parts are not coated or treated to inhibit rust from this excessive moisture. The excessive moisture inside the vehicle also accumulates on the inside windshield of the vehicle as it removed thru the system but re-enters thru the firewall into the floor.

For sometime I have notice that my mat on the driver side is always wet. I'm afraid that the floor is going to give out. Also, my latch on the back just stop working.

Endeavor 6-cyl

  • 75,000 miles
The H-vac system does not work. When air conditioning is used water seeps into the floorboard and completely soaks the floor and mat, which creates a very rank odor. To correct this problem it will cost the consumer approximately $800. This is clearly an engineer defect/flaw. We were told by an Mitsubishi service rep that the following year (2005) it was corrected. Obviously Mitsubishi was aware of this problem. Why wasn't a recall done on this problem" I think it certainly warrants one. How many other people have been affected by this? why should the consumer assume costs for something that was not made correctly? I am baffled, as to why a car corporation would not take care of their customers"

Endeavor 6-cyl

  • 68,000 miles
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.

Endeavor 6-cyl

  • 50,000 miles
Drivers side has wet floor mats, as ac is backed up causing mildew and an unpleasant odor. The whole floor is wet, stretching back to the passengers side. Dealer says they will drill a hole and blow out ac, but not guarantee a permanent fix. This is unsafe because the stepping on wet floor mats make the break and gas pedals wet.

My 2004 Endeavor has had water leaking on driver's side front floor. Based on the volume of complaints in this forum and others, I would suggest that this is an issue that should be recalled and covered as a manufacturer defect. If it is not recalled, perhaps a class action lawsuit is in order.

1.) the driver's side floor in both the front and back are soaking wet. The water is coming from inside the car. My research indicates this is caused by the air conditioner leaking into the car due to a blockage. 2.) I am having to replace another plastic door handle which has come off within the past three months. These plastic handles are cheap and create a danger as ingress into the car is hampered. Door handles should be metal and should not be able to come off!

Water is leaking onto the driverside front floor everytime the air conditioning runs. Mold is growing and the odor is horrible. I must have read at least 300 complaints of this online by other owners of a 2004 Mitsubishi Endeavor, and it is without a question, a design flaw and Mitsubishi will not admitt to this. Rather, they are asking for more than $1200 to fix it. This problem is more than a major inconvenience, it is a health hazard allowing people to inhale mold while driving, not mentioning the other problems that the water is probably causing, such as rust, and potential electrical problems. Mitsubishi should be forced to fix this free of charge, since literally hundreds of Endeavor owners are reporting the very same problem with water on their driver-side floors. Please contact me at [xxx]if anyone has this problem, as well as how we might be able to all get together to force Mitsubishi to take action. Thank you.
