47kW Electric Motor (Y4F1)
Electric
Perform a rapid acceleration test up a steep hill while monitoring the State of Charge (SoC) gauge. | Note: Look for sudden, drastic drops in the SoC bar or a flashing 'turtle' mode light. This indicates weak battery cells or advanced degradation of the 16 kWh lithium-ion pack, which is common in older NZ-imported units.
Turn the cabin heater to maximum heat and verify warm air output within 1-2 minutes. | Note: The iOn uses a high-voltage liquid PTC heater. These are notorious for failing, leaving you with no cabin heating in NZ winters. A replacement unit is extremely expensive due to labor and parts.
Test both AC slow charging (Type 1) and DC fast charging (CHAdeMO) if possible before purchase. | Note: The On-Board Charger (OBC) is a known weak point on these vehicles and can fail completely, preventing slow charging at home. Diagnostic and replacement costs are high.
Listen carefully for a buzzing or humming sound from the front of the vehicle when applying the brakes. | Note: The electric vacuum pump for the brake booster can fail or wear out prematurely. If it runs constantly or is excessively loud, it will require replacement for WOF compliance.
Perform a comprehensive 12V auxiliary battery health test (crucial for EV startup systems), inspect cabin air filter, and conduct a battery State of Health (SoC/SoH) scan via OBD2.
Replace the reduction gearbox oil (transmission fluid), flush the power electronics/battery cooling system, and thoroughly service the brake calipers and sliders to prevent seizing due to high regenerative brake use.
Inspect steering rack ends and suspension bushings for wear, replace the 12V auxiliary battery as preventive maintenance, and perform a deep-cycle battery capacity assessment.
Check and service front and rear brakes annually, focusing on cleaning and lubricating slider pins to prevent rust-seizure from low physical brake usage.
Test the 12V auxiliary battery health at every service; a weak 12V battery causes erratic dashboard error lights and can brick the car.
Replace the cabin pollen filter every 12 to 24 months to maintain HVAC efficiency and prevent window fogging.
Inspect the reduction gear drive-shaft seals for oil leaks, which can lead to catastrophic gearbox failure if run dry.
Clean and inspect the CHAdeMO and Type 1 charging ports for debris, corrosion, or burnt contacts to ensure safe charging.
Estimated repair costs if issues arise
If the battery State of Health (SOH) drops below 50%, the range becomes impractical. Replacement or cell-swapping is a major expense.
Internal capacitors or resistors fail, rendering the car unable to charge on household AC power. Requires specialist EV technician repair.
Failure of the internal heating element. The part is hard to source in NZ and requires high-voltage safety protocols to replace.
