3.5L 2GR-FXE V6 Hybrid (AWD)
Hybrid
While driving at low speeds, listen carefully for any clunking or 'knocking' sounds from the front suspension, as the RX350/450h is known to occasionally develop wear in the sway bar links or control arm bushings over high mileage.
While parked, cycle through the infotainment 'Remote Touch' controller; ensure the cursor moves smoothly without jumping, as the controller assembly can become temperamental in higher-mileage examples.
Check this by idling in 'Ready' mode and observing the transition between the electric motor and the petrol engine; the handover should be seamless, and any harsh vibrations may suggest it is worth having a specialist assess the engine mounts.
Before your drive, inspect the top of the engine and the power steering rack for any signs of seepage, as age-related gasket fatigue can occasionally occur in vehicles of this vintage.
Consider a comprehensive cooling system inspection and a proactive change of the inverter coolant, which is vital for the hybrid system's longevity.
Keep an eye on the spark plugs and ensure the hybrid battery health report is requested, as this is a key milestone for electric-drive efficiency.
At this point, it is wise to have a specialist check the CV boots and suspension struts to ensure the ride quality remains as smooth as Lexus intended.
Ensure the oil is changed every 10,000km using a high-quality synthetic to keep that 2GR-FXE V6 running whisper-quiet.
Keep the hybrid battery intake vents—located under the rear seats—clear of dust and pet hair to prevent the battery from overheating.
Regularly monitor the tire pressure, as the AWD system performs best when all four tires are evenly matched in tread depth and pressure.
Schedule a brake fluid flush every two years, as hybrid regenerative braking systems rely on responsive hydraulic pressure.
Maintain a log of transmission fluid services; while often 'sealed for life', many owners find that a drain-and-fill every 80,000km helps maintain smooth gear transitions.
Estimated repair costs if issues arise
In cars of this age, it is prudent to be aware that hybrid batteries have a finite service life. Should the battery start showing signs of degraded capacity, you might eventually need to budget for a refurbished or replacement unit.
The hybrid cooling system is quite robust, but if this component shows signs of leaking in the future, it is an essential repair to prevent overheating the inverter. Setting aside a contingency fund is a wise move for long-term ownership.
Some higher-spec models feature air suspension. If you notice the car struggling to maintain its level after sitting for a few days, you may want to budget for an eventual strut or compressor service.
