2.4L Turbo Hybrid (T24A-FTS) - RX500h F-Sport Performance
Hybrid/Petrol
Engage the Direct4 AWD system during cornering. Listen for any unusual driveline mechanical noise, as the RX500h uses a unique rear e-Axle that performs best with smooth power delivery.
Cycle through the 'Sport+' drive mode while accelerating from a standstill. Ensure the 6-speed automatic transmission transitions through gears without hesitation, as the hybrid-integrated transmission calibration is specific to this performance model.
Use the infotainment system to check the battery cooling intake vents. Ensure they are free from dust or debris, as efficient airflow is key to maintaining hybrid battery performance in the RX500h setup.
Perform a cold start check. Observe the T24A-FTS engine note; while the turbo-hybrid is naturally more mechanical sounding than the old V6 hybrids, any excessive rhythmic ticking or metallic rattling should be noted for a pre-purchase inspection.
Consider a full hybrid health check and brake fluid flush to maintain the integrity of the regenerative braking system.
Typically when a proactive check of the inverter cooling system and spark plug condition becomes relevant.
A common point to review the long-term health of the hybrid battery cooling fan and drivetrain mounts.
Always use the specific synthetic engine oil grade recommended for the T24A-FTS turbo engine to protect the turbocharger bearings.
Keep up with the 'Lexus Care' service intervals to ensure the sophisticated ECU software updates are current.
Monitor tyre wear closely; the RX500h F-Sport runs staggered widths and high-performance compounds, meaning they can wear faster than a standard SUV.
Have the brake pads checked regularly, though the regenerative system significantly extends their lifespan, they still require physical inspection for seize-prone calipers.
Ensure the panoramic roof drains are kept clear during your annual service to prevent any moisture ingress.
Estimated repair costs if issues arise
If this component requires cooling maintenance or service, it is a specialized task. While not a frequent failure, it is wise to set aside funds for cooling circuit flushing as part of your Future Budget Planning.
The RX500h F-Sport features upgraded braking hardware. When the time eventually comes to replace the performance rotors and pads, it is worth keeping in mind that these are premium-tier parts.
If you ever require a windscreen replacement or alignment adjustment, the front-facing sensors require professional recalibration. For Future Budget Planning, ensure your insurance policy covers glass and sensor recalibration.
