Known Issues
Diesel Crankshaft Seizure:
Some earlier 2.8L CRD engines (though the 2005 is likely the 2.5L CRD from VM Motori, it's worth noting potential CRD issues) experienced crankshaft bearing issues. Specific to the 2.5L CRD, potential issues can include injector pump failures or turbocharger problems if not maintained.
Gasoline Engine Issues:
The 3.7L V6 can experience intake manifold leaks and oil filter housing leaks. The 2.4L 4-cylinder may have occasional issues with head gaskets or piston ring wear.
Suspension Components:
Front lower ball joints and sway bar links are common wear items due to the vehicle's off-road oriented design and body-on-frame construction.
Electrical Gremlins:
Some owners report minor electrical issues, such as sensor failures or intermittent power to accessories, often related to wiring harness connections or grounding points.
Transmission Issues:
The 42RLE automatic transmission is considered somewhat basic; proper fluid maintenance is crucial. Some instances of solenoid pack failure have been reported.
