3.5L 2GR-FXE V6 Hybrid
Hybrid
While at a standstill in 'Ready' mode, gently cycle through the drive modes (Eco, Normal, Sport) and observe the dashboard. | Note: This helps ensure the hybrid system controller is responsive and that there are no lag-induced warning lights flickering under load.
Check this by accelerating briskly from a low speed to listen for any unusual resonance from the CVT. | Note: While these transmissions are robust, any erratic surging or unusual high-pitched whines are worth investigating during your inspection.
During the drive, test the Adaptive Variable Suspension (AVS) by switching between drive modes on an uneven road. | Note: You should feel a distinct difference in damping firmness. If the ride feels consistently harsh or 'bouncy', the electronic dampers may be due for maintenance.
Operate the infotainment joystick and all door locks repeatedly during your inspection. | Note: The Lexus joystick controller and door lock actuators can occasionally show signs of wear in older models; ensuring they feel tactile and responsive is a good sign.
Usually marks the time to consider a hybrid battery health check and a fresh coolant flush for the inverter cooling system.
It is often wise to inspect the suspension bushings and check the drive shaft boots for any signs of perishing.
Consider a preventative inspection of the auxiliary water pump for the hybrid system to ensure continued cooling efficiency.
Verify the hybrid battery cooling fan intake (located near the rear seat) is free of dust and debris for optimal airflow.
Confirm the 12V auxiliary battery, located in the boot, has been replaced in the last 3-4 years as it is vital for system startup.
Check for a consistent service history, ideally using 0W-20 or 5W-30 full synthetic oil to keep the 2GR-FXE engine internals clean.
Ensure the inverter coolant has been replaced according to the manufacturer's recommended intervals to protect the hybrid electronics.
Inspect the brake fluid condition, as the regenerative braking system places specific requirements on the hydraulic fluid's viscosity.
Estimated repair costs if issues arise
While these batteries are renowned for longevity, in cars of this age, it's common to consider a future replacement. Planning for this ensures peace of mind for long-term ownership.
If you notice the suspension feels less composed over time, you might eventually need to budget for refreshing the electronic shock absorbers.
As a critical component for the hybrid system, if this component needs attention in the future, it is a straightforward but essential piece of preventive maintenance.
