📚 Vehicle History

Jeep Legacy:

Building on Jeep's long history of producing capable off-road vehicles, dating back to WWII. The Liberty aimed to capture a segment of this heritage in a more modern and accessible package.

First Generation Kj:

The KJ generation was introduced for the 2002 model year, replacing the Jeep Cherokee (XJ) in North America. It was designed as a unibody SUV with a focus on both on-road comfort and off-road capability, a departure from the XJ's more utilitarian roots.

Mid Cycle Refresh:

The 2005 model year represented a significant mid-cycle refresh for the KJ Liberty, introducing updated exterior styling (front fascia, grille, headlights), interior refinements, and powertrain improvements.

Assembly Locations:

Belo Horizonte, Brazil; Toledo, Ohio, USA

Production Years:

2002-2007 (KJ generation)

🏆 Awards & Recognition

Top Safety Pick:

While specific 'Top Safety Pick' awards from IIHS might vary by year and testing criteria, the 2005 Liberty performed well in NHTSA crash tests for its class.

Consumer Reports Reliability:

Reliability ratings from organizations like Consumer Reports for the KJ Liberty were generally mixed to below average, particularly for early models and the V6 engine. This makes a comprehensive service manual even more valuable for owners.
