Another recall was issued for a problem with the vehicle’s fuel tank, which could lead to fuel leaks and increase the risk of a fire. While these recalls are concerning, they’re relatively common in the automotive industry, and Mitsubishi took steps to correct these issues. When shopping for a used 2006 Endeavor, be sure to check the vehicle’s history to ensure that any necessary repairs were made.


Performance and Handling

The Mitsubishi Endeavor’s performance and handling capabilities have been a mixed bag throughout its model years. While some years offered commendable improvements, others were marred by significant issues. Let’s delve into the specifics and explore what makes each model year stand out.

2004 V6 Engine Problems

The 2004 Mitsubishi Endeavor’s 3.8-liter V6 engine was plagued by problems, leaving many owners frustrated. One of the primary issues was the excessive oil consumption, which often led to premature engine wear. This was accompanied by a tendency to overheat, even when driven moderately. The culprit behind these problems was often a faulty engine computer (ECU) that failed to properly regulate engine performance. As a result, many 2004 Endeavors were plagued by stalling, misfires, and poor fuel economy.

Imagine being stuck in rush-hour traffic, and your Endeavor suddenly sputters to a halt. The last thing you want is to be stranded on the side of the road, watching as other cars whizz by. Unfortunately, this was a reality for many 2004 Endeavor owners. Mitsubishi eventually issued a recall to address these issues, but not before many owners had already experienced the frustration firsthand.

2007 Model Year Suspension Upgrades

Fast-forward to the 2007 model year, and Mitsubishi made significant strides in improving the Endeavor’s suspension. The updated suspension system provided better damping and improved handling, making the Endeavor a more enjoyable ride. The new design also reduced body roll, giving the SUV a more agile feel. This was achieved through the incorporation of new shock absorbers, springs, and stabilizer bars.

Driving an SUV is all about feeling connected to the road, and the 2007 Endeavor’s suspension upgrades delivered. Imagine cruising down a winding highway, feeling confident and in control as you take each turn with ease. That’s what the 2007 Endeavor offered – a driving experience that was both fun and composed.

2009 Model Year Transmission Issues

Unfortunately, the 2009 model year saw a new set of problems emerge, this time related to the transmission. Some owners reported experiencing slipping or hesitation when shifting gears, particularly when accelerating from a standstill. In extreme cases, the transmission would fail to engage properly, leaving the SUV struggling to move.

Imagine being stuck in neutral, with cars honking behind you as you try to get moving again. It’s a frustrating experience, to say the least. The root cause of these transmission issues was often attributed to a faulty transmission control module (TCM) or worn-out transmission solenoids. While Mitsubishi did issue a technical service bulletin to address these problems, many owners were left to deal with the consequences.
