Jeep Liberty KJ (1st Generation)

2002–2007 · KJ · suv

First Jeep with independent front suspension (a rack-and-pinion IFS setup the XJ purists despised). Replaced the iconic Cherokee XJ and was marketed as Jeep Cherokee KJ everywhere except North America. Engines: 2.4L PowerTech I4 (150hp), 3.7L PowerTech V6 (210hp), and 2.5L/2.8L VM Motori diesels for export markets. Built at Toledo North.

Watch out: 3.7L PowerTech V6 valve seat dropping — a documented failure mode where the exhaust valve seats migrate out of the head, causing catastrophic engine damage. Ball-joint failures on the front suspension are also a major safety issue (NHTSA campaign 14V-373 covered some). Window-regulator failures are nearly universal.
