Hybrid/Petrol
Listen for any 'whine' from the electric motor or transmission during acceleration, as the e-CVT system is robust but can develop noise in high-mileage examples.
Cycle through the hybrid battery health by watching the display; if the bars drop rapidly under normal throttle, it is worth asking when the battery was last serviced or replaced.
Check the operation of the adaptive front-lighting system (AFS) by ensuring the warning light on the dash isn't blinking, as these headlamp assemblies are complex and costly to repair.
Test the air suspension (if fitted) by selecting the height adjustment settings; ensure the vehicle rises and lowers evenly without any strange clunking or long wait times for the compressor.
Consider a full hybrid system diagnostic report to ensure the battery cells are still balancing correctly.
The water pump and cooling system components are often due for a preventative check to ensure the inverter cooling system remains efficient.
Suspension bushings and ball joints may show signs of natural wear from NZ road conditions and typically require a refresh for optimal ride quality.
Check the service history for regular synthetic oil changes, which are vital for the longevity of the 3.5L V6 engine.
Inspect the inverter coolant level in the translucent reservoir to ensure it is clean and filled to the mark.
Verify that the hybrid battery cooling fan vent (located under the rear seat) is clear of dust and debris to prevent overheating.
Check the condition of the brake rotors, as the regenerative braking system often makes the physical pads and rotors last longer, but they can seize if not used regularly.
Test all electrical accessories, including the power tailgate and navigation screen, as these older units can occasionally face connection fatigue.
Estimated repair costs if issues arise
While these batteries are renowned for their reliability, if this component needs attention in the future, it is a significant consideration. You might eventually need to budget for a professional re-cell or a full replacement unit.
The inverter is the heart of the hybrid system. Depending on the car's history, you might eventually need to budget for a repair or replacement if you notice the hybrid system warning lights appearing.
If your vehicle is equipped with air suspension, it provides a lovely ride. Should an air strut begin to leak over time, it is common to consider replacing them in pairs to maintain balance.
