Check the transmission during low-speed crawling. | Advice: The 9-speed ZF transmission can sometimes feel a bit hesitant or 'busy' when hunting for the right gear. Pay attention to any clunks or harsh shifting while moving at parking lot speeds.
Check the Uconnect infotainment system for connectivity. | Advice: Test the touchscreen response and ensure your phone pairs via Bluetooth. Electronic glitches in the infotainment module are common in this generation and can be an annoyance to live with.
Check the suspension over uneven road surfaces. | Advice: Listen for any knocking or metallic rattles from the front end. It is common to consider that bushings or control arms may wear out over time on heavier AWD vehicles.
Check for any signs of engine oil seepage. | Advice: When you have the bonnet popped, take a quick peek around the valve covers. While the Pentastar V6 is a strong engine, minor oil leaks can occur as vehicles age.
Consider a full transmission fluid refresh and an inspection of the AWD power transfer unit.
Typically the time to look at the spark plugs, as the intake manifold often needs to be removed for this service on the V6.
Review the cooling system hoses and thermostat, as rubber components start to reach the end of their design life.
Keep the engine oil topped up with the correct synthetic grade to look after that V6 timing chain.
Ensure the transmission fluid has been changed at least once, as these boxes thrive on clean oil.
Check the battery health regularly; Jeeps are quite sensitive to voltage drops which can cause 'ghost' electrical codes.
Keep your coolant fresh to protect the heater core and the engine block from internal corrosion.
Regularly inspect the CV joints and rubber boots during your annual WOF to catch tears before they ruin the bearings.
Estimated repair costs if issues arise
Because the V6 engine layout is quite compact, replacing the spark plugs requires removing the upper intake manifold. Future budget planning should account for a bit more labour time than a standard four-cylinder vehicle.
Depending on the road conditions the car has faced, you might eventually need to budget for new control arms or bushings if the steering starts to feel a bit loose or 'wandering'.
If this component needs attention in the future, it is wise to replace the thermostat and potentially the water pump to ensure the Pentastar engine stays at its optimal temperature.
