3.6L V6 (LGX) - VXR/RS-V AWD models
Petrol
While on a straight, clear road, perform a firm stop from 60km/h. Listen for any vibration or pulling to one side, as the VXR's high-performance Brembo brakes are effective but can be sensitive to uneven rotor wear.
Check the infotainment system by cycling through the Apple CarPlay and Android Auto menus for at least 10 minutes. These early ZB units sometimes experienced screen freezing or connectivity dropouts which are worth noting during your trial.
Ensure the vehicle is at operating temperature, then check the transition between the 9-speed automatic gears. Occasional hesitant shifting is a characteristic of this transmission's programming, but sharp 'clunks' should be assessed closely.
While idling at a stop, observe the engine note for any rattling or irregular ticking. The 3.6L LGX V6 is generally robust, but monitoring for top-end noise is a sensible practice for any high-output engine of this configuration.
Consider a full transmission fluid service to maintain smooth gear transitions, even though it is often listed as a 'sealed for life' unit.
A common point to refresh the AWD transfer case fluid and inspect the suspension bushings for any signs of premature wear.
Ideally inspect the spark plugs and ensure the cooling system is flushed, as this engine benefits from clean coolant to manage heat efficiently.
Check the service history book for consistent oil changes every 10,000 to 15,000km, ideally using the manufacturer-specified dexos-rated oil.
Inspect the tyres for even wear patterns, as the AWD system and the VXR’s performance alignment can lead to increased inner-edge wear.
Verify the battery health; these electronics-heavy vehicles can behave erratically if the battery voltage drops even slightly below optimal levels.
Ensure the climate control functions correctly across both zones, as cabin air quality and temperature regulation are key for long-distance comfort.
Look underneath for any signs of oil seepage around the timing cover, which is a rare but standard check for any V6 engine.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ is higher than a standard sedan due to the VXR's specialized Brembo braking hardware.
Depending on the car's history, you might eventually need to budget for the replacement of a FlexRide damper unit, which is complex and integrated into the car's drive modes.
If the screen or processor unit requires professional attention, it is worth keeping a small buffer as these units often require specialized Holden-specific software calibration.
