2003 — 2006
3.3L (3MZ-FE) V6 - Luxury AWD
Petrol
Gently accelerate and decelerate at low speeds to observe if the 5-speed automatic transmission exhibits any hesitation or gear-hunting, as these units can sometimes feel aged with higher mileage.
Turn the steering wheel fully to both locks while stationary to listen for any groaning sounds from the power steering pump, as seals can occasionally perish over time.
Operate the power-operated tailgate through a full cycle; listen for any grinding noises or sluggish movement, as the motor and strut systems are known to be sensitive as they reach this age.
When parked, observe the dashboard for any flickering or dead pixels in the multi-information display, which is a common quirk for electronics from this era.
Usually marks the second major timing belt service interval, which is critical for the 3MZ-FE engine.
A common point where suspension components like control arm bushings and struts may require a refresh to maintain the trademark Lexus ride quality.
The stage where cooling system components like the radiator and water pump often benefit from preventative inspection.
Check the service history book for evidence of timing belt and water pump replacements every 100,000km.
Ensure the engine oil is a golden or light-brown hue, as the 3MZ-FE performs best with clean, high-quality synthetic oil.
Inspect the underside for any signs of surface rust, particularly if the vehicle has spent significant time in coastal NZ regions.
Test all electrical accessories, including the heated seats and sunroof, to ensure all interior motors are functioning smoothly.
Verify that the AWD system engages without any binding or unusual noises during tight turns in a car park.
Estimated repair costs if issues arise
Since the 3MZ-FE uses an interference engine design, keeping up with this belt replacement is essential for peace of mind. Depending on the car's history, you might eventually need to budget for this if it hasn't been done recently.
If your specific Luxury model is equipped with factory air suspension, it is common to consider that these airbags may eventually lose their elasticity over time. If this component needs attention in the future, the estimated cost in NZ is significant but ensures the car retains its 'magic carpet' ride.
To keep the RX330 driving like a Lexus, you might eventually need to budget for a refresh of the suspension bushings and shock absorbers to tighten up the handling.
