Petrol
Check the transmission shift quality by gently accelerating from a standstill in both 'Normal' and 'Sport' modes. | Observation: Some owners have noted occasional hesitation in the 6-speed automatic; ensure the shifts feel smooth rather than jerky.
Check the infotainment system by using the Lexus 'Remote Touch' joystick controller while parked. | Observation: The mouse-like interface can be quite sensitive and distracting; ensure you find it intuitive enough for your daily driving needs.
Listen for any whistling or wind noise by driving at highway speeds (80-100km/h) and checking the seals around the side mirrors. | Observation: In some Fourth Gen models, wind noise can develop around the A-pillars, which is often rectified by seal maintenance.
Check the turbocharger responsiveness by performing a moderate overtake maneuver on a safe stretch of road. | Observation: The 2.0L turbo engine is efficient, but you want to ensure the power delivery is linear and free of unusual high-pitched whining noises.
Typically requires a major service, including spark plug replacement and a thorough inspection of the turbo cooling system.
A common point to evaluate the condition of the suspension bushings and potential replacement of water pump components.
Focus on deeper engine bay inspections, checking all major rubber hoses and the condition of the drivetrain fluids.
Check that the service history shows regular oil changes every 10,000km to keep the 8AR-FTS turbo internals happy.
Inspect the cabin air filter to ensure the climate control system remains efficient and the air quality is fresh.
Verify the brake fluid has been flushed as per the manufacturer's schedule to maintain responsive stopping power.
Inspect all four tyres for even wear patterns, which helps confirm that the AWD alignment is currently set correctly.
Check the battery health, as the advanced electronics in the RX series perform best with a strong, consistent charge.
Estimated repair costs if issues arise
If this component needs attention in the future, it is worth noting that while Lexus turbos are robust, preventative cleaning and hose checks help longevity. Depending on the car's history, you might eventually need to budget for specialized inspection or minor hose replacements.
Over our NZ roads, suspension components do their fair share of work. If you notice a knock or an unsettled ride as the vehicle ages, it's common to consider refreshing the bushings or shocks for that trademark Lexus comfort.
Lexus transmissions are generally excellent, but regular fluid exchanges are the secret to long life. If it hasn't been done, it is a great piece of future budget planning to ensure the transmission stays smooth.
