The Endeavor debuted in 2004 as a new mid-size crossover SUV offering from Mitsubishi. The Endeavor had design roots in a late-1990s concept, but very little was carried over to this production model.  

Unfortunately, the first version of this SUV was hampered by build-quality issues during its initial run, and Mitsubishi was forced to re-release the Endeavor as a 2004.5 model. Key improvements included more horsepower, improved safety features, and a more comprehensive ABS system.

The Endeavor was available in three trim levels, and each was offered with either front or all-wheel drive. Styles include the base LS, mid-level XLS, and the luxurious Limited. All models come standard with air conditioning, cruise control, full power accessories, remote keyless entry, privacy glass, alloy wheels, and a CD player.

The Endeavor lineup features one power plant: a 3.8-liter V-6. This engine supplies 225 horsepower and 255 pound-feet of torque and is paired with a four-speed automatic transmission with a manual shift feature. Fuel economy is estimated at 17/21 mpg.

The Endeavor has earned positive reviews for build quality, interior room, safety, and ride quality.  The Endeavor is quite spacious for a mid-size crossover, but it falls to the middle of the pack with respect to cargo room. The SUV offers plenty of storage options however, with an abundance of cabin bins and tie-down hooks. Second-row seats fold flat, and owners don't need to remove headrests to do so.

Reviewers agree that passengers will enjoy a cushioned but controlled ride, with minimal body roll and very predictable steering. The cabin is adequately shielded from noise intrusions, and the interior layout features well-placed controls and a stylish presentation.
