2.7L 1AR-FE I4 (FWD)
Petrol
Perform a low-speed crawl and listen for suspension clunks. | Description: It is worth keeping in mind that these models can eventually develop wear in the front lower control arm bushings, which might cause a subtle rattle over bumps.
Shift through all gears while stationary, then again at highway speeds. | Description: While generally reliable, the 6-speed transmission should shift smoothly; any hesitation might suggest a need to verify the transmission fluid service history.
Check the interior climate control by cycling through all temperature zones. | Description: Occasionally, the servo motors that control the air mix flaps can become stiff in older imports, so ensure the temperature changes promptly when requested.
Inspect the dashboard top for any signs of surface distortion. | Description: Due to New Zealand’s high UV index, some third-generation Lexus models have shown susceptibility to dash surface degradation, so it is helpful to verify the condition during your daytime inspection.
Consider replacing spark plugs and performing a comprehensive coolant flush.
Often a good interval to have the suspension components inspected for minor play and to check the accessory drive belt for signs of fatigue.
Monitor the transmission fluid health and ensure the engine mount condition is still providing a smooth ride.
Verify the engine oil has been changed consistently, ideally every 10,000km, as the 1AR-FE engine benefits from fresh lubricant.
Check the condition of the cabin air filter to ensure the climate control system performs efficiently.
Inspect the brake pads and discs, as the RX is a heavier vehicle and can wear through these components depending on city-driving frequency.
Ensure the battery is healthy, as modern electronics in these vehicles can be sensitive to low voltage.
Check for any signs of weepage around the engine valve cover gaskets during your pre-purchase inspection.
Estimated repair costs if issues arise
The 1AR-FE engine occasionally shows signs of water pump seepage as mileage increases. If you notice a faint coolant smell or minor residue, it is a routine maintenance task to address.
If you notice the steering feels less precise or the ride quality diminishes over time, refreshing the front lower control arm bushings can significantly restore that 'Lexus' feel.
Depending on the vehicle's history, an ignition coil might eventually need replacing if you experience a slight engine hesitation, which is a common item to address on higher-mileage I4 engines.
