Summary Verdict

The 2006 Jeep Liberty, particularly models equipped with the 3.7L V6 or the 2.8L CRD diesel engine, can be prone to specific powertrain issues such as valve cover leaks, intake manifold problems, and turbocharger or glow plug failures in the diesel. The 42RLE automatic transmission may exhibit shifting problems. Suspension components like ball joints and control arm bushings are also noted areas for potential wear. Electrical gremlins, often linked to the Body Control Module or window regulators, are not uncommon. While generally capable, potential buyers should be aware of these common issues and factor in potential repair costs for a vehicle of this age.
