Monitor the state-of-charge gauge during a steep hill climb to observe any 'battery droop' or rapid drops, which can indicate diminished individual cell health in older packs.
Listen for any light clicking or 'clunking' from the rear when moving from a standstill, as this can suggest wear in the rear drive shafts, common in high-torque electric setups.
Check for smooth operation of the regenerative braking system by lifting off the accelerator; it should feel consistent and predictable rather than 'jerky' or inconsistent.
Confirm the functionality of the cabin heater and air conditioning during the test drive, as these systems are energy-intensive and can sometimes show signs of sluggish performance in early i-MiEV units.
Consider a full diagnostic scan of the Battery Management System (BMS) to confirm health percentage.
Typically the time to inspect suspension bushings and shock absorbers for signs of wear due to NZ road conditions.
Recommended interval to check the reduction gear oil and the condition of the high-voltage cable insulation.
Keep a regular eye on your tire pressures, as the i-MiEV's efficiency and range are quite sensitive to rolling resistance.
Ensure the 12V auxiliary battery is tested annually; it powers the car's electronics and is often the primary reason for a 'no-start' condition.
Periodically clear debris from the air intake vents located near the rear doors to ensure the battery pack stays well-ventilated.
Check the brake fluid condition; even though regen does much of the work, the hydraulic fluid needs to remain fresh to prevent corrosion in the calipers.
Always use a high-quality, inspected charging cable and, if possible, have a certified electrician check your home charging socket.
Estimated repair costs if issues arise
As these vehicles age, the traction battery may naturally lose some usable capacity. If you find the range no longer meets your daily commuting needs, you might eventually need to budget for professional battery reconditioning or cell balancing.
The DC-DC converter keeps your 12V battery charged while driving. If it shows signs of failure, it is a specialized repair. It is worth keeping a small buffer for electrical diagnostics in your Future Budget Planning.
Given NZ road surfaces, suspension components like control arm bushings and struts often require attention after a decade of service. This is a standard wear item for any small city car.
