Electrical system: softwareReported October 20, 2010 · 19,410 vehicles affected

Risk
This condition could affect defroster performance, resulting in poor windshield visibility and potentially cause a crash.
Remedy
Dealers will inspect for damage and if necessary repair the mode door shaft free of charge. The safety recall began on december 7, 2010. Owners may contact mitsubishi at 1‑800‑222‑0037.

Recall number 10V514000 · Recall details

Fuel system, gasoline: storage: tank assembly: filler pipe and capReported February 25, 2010 · 108,147 vehicles affected
What is wrong
Mitsubishi is recalling certain model year 2004-2010 endeavor vehicles originally sold in or currently registered in the states of connecticut, delaware, illinois, indiana, iowa, kentucky, maine, maryland, massachusetts, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, virginia, west virginia, wisconsin, and washington d.c. Cold states include north dakota, south dakota, nebraska, kansas, oklahoma, colorado, wyoming, montana, idaho, washington, oregon, and utah. Adjoining states include arkansas, tennessee, and north carolina. In severe corrosive environments where road salts are frequently used in winter vehicles may be exposed to road debris (mud) mixed with road salt. This material can become trapped between a reinforcing bracket and the fuel filler pipe, potentially causing corrosion. Over time, corrosion could create a leak in the fuel filler pipe that could result in a fuel leakage when fueling the vehicle.
Risk
Fuel leakage, in the presence of an ignition source, could result in a fire.
Remedy
Dealers will replace the fuel filler pipe with a new improved part free of charge. The safety recall is expected to begin on or before july 5, 2010. Owners may contact mitsubishi at 1‑800‑222‑0037.

Recall number 10V065000 · Recall details

Fuel system, gasoline: storage: tank assemblyReported September 9, 2008 · 45,988 vehicles affected
What is wrong
Mitsubishi is recalling 45,988 my 2005-2007 endeavor, galant, eclipse coupe, and my 2007 eclipse spyder vehicles. The bracket that is the attachment point for the left rear fuel tank mounting strap may have been improperly formed during a metal stamping process. The process may have caused the metal to have a split in the area where the bolt that holds one of the two fuel tank straps to the underside of the vehicle is located. In the event the fuel tank is full and the vehicle is subject to a severe collision, the bracket may break and allow the fuel tank to drop down, possibly causing a fuel leak.
Risk
Fuel leakage in the presence of an ignition source could result in a fire.
Remedy
Dealers will inspect to see if the left rear fuel tank strap mounting bracket has splitting beyond a specific limit. Vehicles with moderate to severe splitting will be repaired using a reinforcement cap, a special structural adhesive, and a rivet to reinforce the fuel tank mounting bracket. The recall began on september 20, 2008. Owners may contact mitsubishi at 1‑800‑222‑0037.

Recall number 08V454000 · Recall details

Electrical system: ignitionReported March 26, 2008 · 116,600 vehicles affected
What is wrong

During vehicle use, the ignition key interlock cable (which is a component of the interlock system) may allow the interlocking cam to fall forward and allow the ignition key to be removed from the ignition switch when the gearshift mechanism is not in the park position.
Risk

"The fuel filler neck has rusted through and is actively leaking liquid gasoline when the tank is filled past 3/4, creating an active fire hazard. While Safety Recall 10V‑065 shows as completed for this VIN, the original manufacturer remedy has completely failed. Furthermore, the local dealership refuses to inspect or address this failed safety recall without a $193 diagnostic fee, and Mitsubishi Corporate has ignored multiple email inquiries since April. I am requesting a federal review because the vehicle remains unsafe due to a failed recall remedy and the manufacturer refuses to provide a free fix."

I just had to pay for a repair for the fuel filler pipe. It was leaking as I would fill the car with gas. This model had a recall for this problem but my car VIN was not included.t he part they put down on the bill was "the recall kit". I feel that mine should have been covered also.

A.c. Is draining into the interior of the vehicle causing the carpet and flooring on the driver side under to the driver seat to become soaked through and will not drain out. On several occasions, footwear have slipped on the break and gas pedals due to moisture accumulated on the bottom of the shoe. The shoe is not able to dry and properly grip the gas and brake pedals due to the accumulated moisture soaked through the carpeting under foot. Have contacted local mitsubishi dealership: the a.c. Issue is a known issue and they will not cover the cost of repair even though it is causing safety issues with vehicle stopping and accelerating. Contacted mitsubishi corporate and received the same communication that was relayed by the local dealership.

The AC gets cold on the driver side but the passenger side only the heat works. You can change the temperature but nothing happens it will remain the same. I took my car to the dealer and was told that there is no recall concern ing this issue but from what I have gathered from other customers who own this type of dr they are having the exact same issue. The dealer can't figure out what is the problem and I paid $1,600 for an unfixed AC unit.

Originally the liftgate would not open only the glass top would open. A common issue according to several mitsubishi endeavor owner forums for endeavors from 2004 to 2008. Recently both liftgate and glass would not open at all unless I used the manual release located on the inside part of the liftgate. However, while driving recently the liftgate and or glass top actuated itself causing the liftgate to unlock on its own and open. If it were not for the dinging of the dash informing me one of my doors was open I would have never noticed. This could have caused the contents of my trunk to spill out on the road and only god knows what could've happened. My mechanic recommended I change both latches to be safe ($100 each) however this is a reoccurring problem so it would only be a matter of time before I'd be back having to replace them again. I verified this with testimonials from other endeavor owners via multiple forums and repair blogs....
