NHTSA lists 5 safety recalls and 20 owner complaints for the 2006 Mitsubishi Endeavor. Most complaints involve fuel/propulsion system (6) and electrical system (5). The EPA rates it 17–18 mpg combined.
MITSUBISHI IS RECALLING CERTAIN MODEL YEAR 2006-2008 ENDEAVOR WITH MANUAL AIR CONDITIONING. DUE TO AN INCORRECT HEATER (HVAC) CONTROLLER SIGNAL, THE AIR FLOW FROM THE AIR VENTS MAY RANDOMLY CHANGE DIRECTION AND/OR THE TEMPERATURE MAY BRIEFLY CYCLE BETWEEN HOT AND COLD.
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.
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.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“"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."”
