4.6L V8 (1UR-FSE) - LS460 Flagship
Petrol
Test drive task: Find a quiet road, come to a complete stop, and then gently accelerate. | Observation: Be mindful of any hesitation or 'clunking' when transitioning from a standstill, as the 8-speed automatic transmissions in these models can occasionally show signs of wear in the valve body or torque converter.
Check this by: Turning the steering wheel fully to the left and right while parked on a flat surface. | Observation: Listen for any distinct whining or groaning noises, as the electric power steering racks and associated components can occasionally develop issues as the vehicle ages.
While driving: Pay attention to the ride quality over uneven surfaces or speed bumps. | Observation: If the vehicle is equipped with the air suspension system, check that the car levels itself properly and note if the ride feels overly firm or harsh, which could indicate a potential leak or sensor issue.
Before starting: Check the infotainment and instrument cluster screen for any 'bleeding' pixels or flickering. | Observation: The early LS460 models feature sophisticated electronics, and it is worth verifying that all the high-tech interior amenities are functioning as intended, as these systems can be complex to repair.
Usually marks the point where the initial suspension bushings and control arms might begin to show signs of fatigue from NZ road conditions.
A common window to verify the service history for the transmission fluid and differential oils to ensure longevity.
At this stage, it is prudent to monitor the cooling system components and accessory drive belt tensioners for signs of aging.
Verify that the engine oil has been changed consistently using the manufacturer-recommended synthetic grade.
Inspect the brake rotors and pads, noting that the LS460 is a heavy vehicle and consumes consumables at a steady rate.
Ensure the cabin air filter has been replaced regularly to keep the climate control system operating efficiently.
Check for any signs of weeping around the engine valley plate, a common area to monitor in the 1UR-FSE engine.
Confirm that all electronic adjustment features for the seats and steering column are moving smoothly without unusual motor sounds.
Estimated repair costs if issues arise
If the car is fitted with air struts, these can naturally reach the end of their service life. If you notice the car 'sinking' overnight or riding uncomfortably, you might eventually need to budget for replacing the strut units.
The LS460 uses a complex multi-link suspension setup. To maintain that signature Lexus 'magic carpet' ride, you may find it necessary to budget for a front-end suspension refresh as the rubber bushings degrade over time.
While reliable, the complex braking system incorporates an electric actuator. If you see warning lights on the dash related to the ABS or VSC systems, it is helpful to be aware that this component is a major part of the braking circuit.
