4.6L 1UR-FSE V8 (255kW) - GS 460
Petrol
While driving at low speeds, listen for a repetitive 'clicking' or 'buzzing' sound from the brake actuator assembly. In cars of this age, it's common to consider the health of the electronic brake booster system, as any excessive cycling could suggest future maintenance needs.
After a thorough test drive, inspect the 'valley' area between the engine banks with a flashlight. Depending on the car's history, you might eventually need to budget for a coolant valley plate reseal if you notice any dried pink crust, which is a common point of attention for the 1UR-FSE engine.
On a quiet, smooth stretch of road, cycle through the suspension modes (Sport/Comfort) to feel for distinct changes. If the car is equipped with Adaptive Variable Suspension (AVS), it is prudent to check for any hydraulic misting on the shock absorbers, as original replacements are specialized components.
While accelerating through the gears, pay close attention to the smoothness of the 8-speed transmission. In cars of this age, it's common to consider the history of the transmission fluid; any hesitation or 'hunting' between gears might suggest that a specialized fluid service should be prioritized.
Major service interval including replacement of long-life Iridium spark plugs and a comprehensive inspection of the drive belts.
Estimated time to assess the condition of the water pump and the front suspension bushings, which may begin to show age-related wear.
Consider a preventative replacement of the coolant hoses and a deep clean of the D-4S fuel injection system to maintain optimal efficiency.
High-mileage check of the alternator and the condition of the differential oil to ensure continued long-distance touring reliability.
Ensure only high-quality 95 or 98 octane fuel has been used to keep the direct-injection system clean.
Check the service history for regular oil changes using the correct 5W-20 or 0W-20 synthetic oils to protect the VVT-i system.
Verify that the sunroof drains are clear of debris to prevent moisture buildup in the New Zealand climate.
Inspect the condition of the interior dash and door card materials, as some early models can experience 'stickiness' in high UV environments.
Confirm that the battery is in top health, as the GS 460's extensive electronics are sensitive to voltage fluctuations.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ is reflective of the complex electronic-hydraulic nature of the part. It is a known wear item for this generation of Lexus GS.
Depending on the car's history, you might eventually need to budget for this labor-intensive job. It involves removing the intake manifold to reseal the area where coolant can slowly seep over time.
If these components need attention in the future, the cost is higher than standard shocks due to the electronic damping tech. Some owners choose to budget for a full set to maintain the original factory ride quality.
In cars of this age, it's common to consider that the audio amplifier (located in the boot) can be sensitive to moisture. If the sound system fails, specialized repair or a refurbished unit is usually required.
