3.5L V6 24V DOHC (2GR-FSE) - AWD i-Four
Petrol
While starting the engine from a cold state, listen for a brief 1-2 second metallic rattle. In cars of this age, it's common to consider the condition of the VVT-i gear actuators, which may eventually require attention to maintain the engine's signature smoothness.
While performing tight U-turns or low-speed maneuvers, feel for any binding or 'hopping' sensation from the drivetrain. With the AWD i-Four system, it is helpful to verify the service history of the transfer case and differential fluids to ensure the electronics and mechanicals are working in harmony.
While driving over speed bumps or varied road surfaces, toggle the AVS (Adaptive Variable Suspension) switch between Normal and Sport modes. If the car feels excessively 'floaty' or fails to stiffen up, you might eventually need to budget for electronic strut replacements which are specific to this trim.
While stopped at a red light after the engine is warm, observe the tachometer for any stumbling or dipping below 600 RPM. Because the 2GR-FSE engine utilizes direct injection, it is common to monitor for carbon buildup on the intake valves, which can occasionally impact the idle quality over time.
Spark plug replacement and a comprehensive check of the cooling system components.
Inspection of all suspension bushings and potential renewal of the water pump and serpentine belt.
Deep service of the AWD system fluids and an assessment of the alternator's charging health.
Verify the oil change intervals; 5,000km to 10,000km is ideal for the 2GR-FSE engine's longevity.
Check the condition of the dashboard and interior door panels for 'stickiness', a known Lexus warranty item.
Inspect the boot floor and sunroof drains for signs of moisture or previous water ingress.
Confirm the age of the 12V battery, as these cars are heavy on electronic power steering and sensors.
Assess the brake rotor thickness, as the GS350 is a heavy vehicle and the AWD model uses specific front rotor offsets.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ covers a high-quality pump, fresh Toyota Super Long Life Coolant, and the labour involved in the somewhat tight engine bay.
Depending on the car's history, you might eventually need to budget for these electronically adjustable shocks if they begin to weep fluid. They are more specialized than standard struts.
In cars of this age, replacing the long-life iridium plugs is a labor-intensive task due to the intake plenum needing to be removed. It's a great time to inspect for carbon buildup simultaneously.
If the AWD system requires a seal replacement or a full fluid flush in the future, the cost reflects the specialized gear oil and the technical labour required to access the transfer unit.
