3.0L 3GR-FSE V6 (183kW) - GS 300
Petrol
While idling at a stoplight, feel for any slight shivers or rough idling, as in cars of this age, carbon buildup on the intake valves of the 3GR-FSE engine is a common point for consideration.
Drive over a series of speed bumps or uneven surfaces and listen for any knocking sounds, as the factory rear shock absorbers are known to potentially develop leaks over time.
After your test drive, check the front of the engine bay with a torch for any faint pink crusty residue, which could indicate the water pump might eventually need attention.
While driving on a coarse-chip road, turn off the audio system to listen for 'ticking' or 'creaking' from the dashboard, which is a characteristic interior trait of this generation.
Major service interval including Iridium spark plug replacement and a thorough inspection of the cooling system components.
Consider a proactive transmission fluid health check and an inspection of the alternator output levels.
Typical timing for a suspension refresh (bushings and dampers) and a deep clean of the intake system to maintain fuel efficiency.
Verify the condition of the dashboard and door card materials for any 'stickiness' common in NZ's high-UV environment.
Confirm the operation of the Adaptive Front-lighting System (AFS) and check for any warning lights on the cluster.
Check the service history for regular oil changes, which are vital for the VVT-i system's longevity.
Inspect the inner edges of the tyres for uneven wear, suggesting an alignment or bush replacement might be due.
Ensure the touch-screen infotainment system and reversing camera are responsive and free of 'dead zones'.
Estimated repair costs if issues arise
Depending on the car's history and fuel quality used, you might eventually need to budget for a manual walnut blast or chemical clean to restore smooth idling and performance.
If these components need attention in the future, the estimated cost in NZ covers a pair of quality dampers to maintain that signature Lexus ride quality.
In cars of this age, it's common to consider replacing the water pump and drive belts as a preventative measure to avoid overheating risks.
If the climate control begins to make clicking noises, you might eventually need to budget for the replacement of these small electric motors behind the dashboard.
