Check for uneven inner tire wear by turning the front wheels fully to one side; in cars of this age, the factory lower control arm bushings can be quite soft, potentially leading to premature wear on the inner edges of the front tires.
While testing the infotainment system, interact with all areas of the screen to check for non-responsive zones or visual 'delamination'; depending on the car's exposure to heat, some owners have noted the screen surface can eventually show signs of wear.
While the engine is idling, listen carefully for any faint whining or chirping sounds from the front of the motor; it is common to consider the condition of the water pump around the 100,000km mark as they may eventually weep coolant.
Test all four door locks multiple times using the key fob and the interior switch; it's worth checking if the actuators engage consistently, as these are components that some owners choose to refresh over time.
This is a great time to verify if the engine air filters and cabin filters have been refreshed, and to check the status of the differential fluid.
Many owners consider a comprehensive inspection of the spark plugs and the serpentine belt to ensure continued smooth operation of the V6 power plant.
In many cases, this is a sensible time to budget for a cooling system inspection and potentially a transmission fluid refresh to maintain that signature Lexus shift quality.
At this stage, it's common to look at suspension components like dampers and bushings to ensure the car still provides its original balance of comfort and handling.
Verify a history of high-quality synthetic oil changes every 10,000km to protect the sophisticated D4-S injection system.
Ensure the brake fluid has been flushed every 2-3 years to maintain the performance of the high-friction braking system.
Check that the sunroof drains are clear of debris to prevent any potential moisture entry during heavy New Zealand rain.
Confirm the battery is in good health, as the IS350's various ECUs are sensitive to voltage drops during start-up.
Inspect the condition of the engine's accessory belt for any signs of small cracks or glazing.
Estimated repair costs if issues arise
If you notice the steering feels slightly vague or inner tires are wearing quickly, you might eventually need to budget for upgraded or OEM bushings to restore precision.
Because the 2GR-FSE engine bay is quite compact, the labor involved to reach all six plugs is a bit higher than a standard sedan; it's a great task to plan for every 90,000km.
Depending on the car's history, you might eventually need to budget for a new water pump if any pink crusting (coolant residue) is spotted during a routine service.
If the screen becomes difficult to use due to 'ghost touches' or delamination, a replacement unit may be considered; some owners opt for refurbished units or specialist repairs.
