5.7L (HEMI V8) - Overland/Summit
Petrol
Navigate to a quiet area and perform a slow-speed lock-to-lock turn to listen for any groaning or metallic clicks from the suspension and steering rack, as components in the WK2 can show signs of wear at higher mileages.
Cycle through the Quadra-Lift air suspension settings while parked on level ground; verify the vehicle rises and lowers smoothly within a reasonable timeframe, as the compressor and bags may eventually require attention.
During steady-state cruising at 80km/h, pay close attention to the dashboard and cabin for any subtle vibrations or shuddering, which can sometimes indicate the torque converter or transmission mounts may need inspection.
Ensure the Uconnect infotainment system remains responsive during the entire drive, specifically testing the touch response and climate control integration, as electrical gremlins are occasionally noted in models of this age.
Usually the time to inspect the cooling system, including water pump health and radiator hose integrity.
A common interval to check the condition of the air suspension components and the primary driveline bushings.
Recommended point to audit the spark plug health for the HEMI V8 and assess the transmission fluid condition.
Prioritize regular engine oil changes using the specific synthetic grade recommended for the HEMI to keep those variable valve timing systems happy.
Monitor the coolant levels and check for any signs of debris or leaks around the water pump housing.
Keep the air suspension system clean and check the lines for any visible signs of fatigue or cracking.
Ensure the battery is in peak condition, as modern Jeeps are sensitive to voltage fluctuations which can trigger false warning lights.
Inspect the CV joint boots regularly to prevent dirt ingress, which helps extend the life of the front drivetrain.
Estimated repair costs if issues arise
If the vehicle begins to sag overnight or the compressor struggles to lift the vehicle, you might eventually need to budget for a repair. It's a complex system, so it's wise to set aside funds for potential sensor or pump replacement.
In high-mileage HEMI models, you may occasionally experience transmission shudder. If this develops, it often requires a torque converter replacement to restore smooth shifting.
Given the age of these vehicles, the plastic cooling components can become brittle. As a proactive measure for long-term ownership, consider budgeting for a radiator or hose refresh.
