While accelerating at low speeds, listen for any 'shudder' or hesitation. In older QG15DE engines, it is common to consider the health of the Mass Air Flow (MAF) sensor, which can occasionally cause rough idling if it becomes dirty or faulty.
Check the gear transitions by gently accelerating through the gears. On high-mileage examples, you might notice the automatic transmission shifts are less crisp, so keep an eye out for any delayed engagement when moving from Park to Drive.
Before starting the engine, turn the key to the 'On' position and watch for the dashboard warning lights. Ensure the check engine light illuminates briefly and then disappears, as this confirms the bulb hasn't been removed to hide any stored fault codes.
When stationary, turn the steering wheel lock-to-lock in a quiet area. In cars of this age, it's common to consider the power steering pump's condition, so listen for any persistent whining noises that could indicate the system is working harder than it should.
Usually marks a time to inspect engine mounts for vibration and ensure the cooling system components like the thermostat have been replaced.
Often the point where original suspension bushings and shock absorbers may show signs of wear, potentially affecting ride comfort.
Consider a full check of the auxiliary belts and the alternator, as these components have likely served a long life.
Check the engine oil colour and consistency; clean, amber oil is a great sign of a car that has been looked after.
Inspect the coolant reservoir for a bright green or red hue; ensuring there is no 'milky' residue is key to peace of mind.
Test all interior electrics, including the air conditioning and window switches, as these older systems appreciate regular exercise.
Look at the tyre tread depth across the whole width to ensure the car is tracking straight and wearing its tyres evenly.
Verify that the spare tyre, jack, and wheel brace are present in the boot for those unexpected moments on the road.
Estimated repair costs if issues arise
As these cars age, the rubber components in the suspension may become brittle or worn. If this component needs attention in the future, the estimated cost in NZ is usually centered around refreshing the bushings or replacing the shocks to restore that smooth 'Sunny' ride.
Depending on the car's history, you might eventually need to budget for a sensor replacement if you notice a drop in fuel economy or sluggish performance. It's a common part that is widely available for the QG engine range.
Electrical components have a natural lifespan. If you find the car taking a little longer to start or the lights dim slightly, you might eventually need to budget for an auto-electrician to refresh these units.
