2.5L 2AR-FSE I4 Hybrid - Combined Output: 164kW (Engine: 131kW / Motor: 105kW)
Petrol Hybrid
Navigate through several core system menus to verify the functionality of the upgraded 10.3-inch Remote Touch infotainment screen, checking for intermittent display freezing, navigation map loading errors, or Bluetooth disconnection faults.
During the road test, monitor all active safety components within the newly introduced Lexus Safety System+ suite, ensuring the pre-collision radar sensor and the upper windscreen camera operate without picking up calibration fault codes.
Before commencing the drive, inspect the revised front bumper lower aerodynamic trim and plastic undertrays for scraping damage or broken clips, as the refreshed styling features a lower front overhang profile.
Pay close attention to the vehicle braking feel during low-speed deceleration, and check the rear brake caliper sliders for localized corrosion or binding, which remains a prevalent issue on these mid-period models.
Conduct a standard comprehensive major mechanical service including the replacement of factory Iridium spark plugs and execute a calibration check on the Lexus Safety System+ radar and camera arrays.
Execute a full thermal management system refresh by draining and replacing both the primary internal combustion engine coolant and the dedicated separate hybrid inverter cooling circuit fluids.
Engage a certified high-voltage specialist to conduct an advanced state-of-health test on the hybrid battery pack to analyze internal resistance and plan for long-term cell efficiency, alongside an inspection of the active safety sensor arrays.
Verify the documented vehicle service history for strict adherence to high-quality synthetic oil changes every 10,000 to 15,000 km to protect the 2AR-FSE direct/port injection system.
Remove and clean the hybrid battery high-voltage cooling fan impeller and check the cabin intake grille ducting for blockages to prevent high-load thermal degradation.
Test the cold cranking amps and standing voltage of the 12V auxiliary AGM battery located in the boot, as low voltage directly triggers sporadic dashboard error codes.
Mechanically slide, clean, and lubricate the rear brake caliper slide pins with high-temperature silicone grease during routine servicing to prevent premature pad binding.
Ensure the diagnostic scanner reads no fault codes or alignment drift parameters for the lane departure alert camera and adaptive radar cruise control modules.
Estimated repair costs if issues arise
Replacing a degraded high-voltage battery pack with a brand new OEM genuine unit through Lexus or Toyota New Zealand dealership channels typically requires a substantial investment, whereas third-party cell reconditioning offers a lower-cost temporary alternative.
If the front radar sensor is misaligned due to a minor stone impact or bumper removal, recalibration at an authorized specialist center using precise target boards is mandatory to restore cruise control safety systems.
If water ingress or moisture short-circuits the factory amplifier hidden in the rear quarter panel of the boot, sourcing a brand new OEM replacement is highly expensive, forcing most owners to seek specialized local component-level electronics repair.
Restoring factory steering precision and eliminating low-speed front-end clunks requires pressing out the worn rubber control arm bushings and installing revised OEM or heavy-duty polyurethane components.
