Petrol
Cycle through the Uconnect infotainment system while stationary to ensure the touchscreen is responsive and the navigation loads without freezing, as software glitches can occasionally occur.
Listen closely for any suspension clunks when going over speed bumps or uneven surfaces, as the complex air suspension on higher trims may eventually require inspection.
Check the electric tailgate operation by opening and closing it multiple times; ensure it latches smoothly without stopping mid-way, as the sensors can sometimes become sensitive.
While driving at low speeds, observe the transmission shifting behavior; ensure the 8-speed automatic transitions smoothly through the gears without hesitation or harsh engagement.
Consider a full transmission fluid and differential service to keep the drivetrain feeling sharp.
A common point to check suspension bushings and the condition of the spark plugs specifically for the 3.6L Pentastar engine.
Review the status of the cooling system components and water pump, as these are natural wear items at this stage.
Keep up with the engine oil changes every 10,000 to 12,000km to ensure the variable valve timing system stays in peak condition.
Regularly inspect the tyre tread depth, as the heavy kerb weight of the Grand Cherokee can lead to faster tyre wear if not rotated.
Check the battery health periodically, as modern Jeeps have complex electronics that prefer a strong, healthy voltage.
Ensure the panoramic sunroof tracks are kept clear of debris to prevent any binding or motor strain during operation.
Keep the service book up to date with an authorised Jeep specialist to maintain the vehicle's resale value and software update history.
Estimated repair costs if issues arise
If the vehicle is equipped with air suspension, it's wise to consider that air bags and compressors are components that may require attention in the future. Depending on the car's history, you might eventually need to budget for a replacement of these units to maintain that smooth ride quality.
After significant mileage, it is common to consider that control arms and bushings may start to show signs of wear. If this component needs attention in the future, the estimated cost in NZ covers parts and labour for a full front-end refreshment.
To keep the Pentastar engine running at optimal temperatures, the cooling system may eventually require a refreshed thermostat or radiator hoses. Planning for this as a preventative measure ensures reliable long-term ownership.
