Monitor the State of Health (SoH) display on the dashboard while driving, as a significant drop in percentage during acceleration may indicate the battery pack is nearing the end of its useful service life.
Cycling through all climate control settings, specifically testing the heater, as the electric PTC heater or heat pump system is vital for demisting the windscreen and can be an expensive component to repair if faulty.
Pay close attention to the regenerative braking feel; if the car feels like it is 'freewheeling' or not slowing down as expected when you lift off the accelerator, the 12V auxiliary battery or the inverter controller might be experiencing communication issues.
Look for signs of damage or corrosion around the high-voltage battery casing, particularly if the vehicle has spent time in coastal regions, as seal integrity is essential for long-term safety and performance.
Consider having the battery cooling fan intake filters cleaned to ensure the pack maintains optimal temperature during charging and operation.
It is often a good time to inspect the reduction gear oil; while not always highlighted in basic service schedules, fresh oil helps maintain smooth power delivery from the motor.
Consider a professional evaluation of the suspension components, as the weight of the battery pack can place extra stress on bushes and struts over high mileage.
Keep the 12V auxiliary battery healthy, as these cars rely on it to 'wake up' the main high-voltage system.
Regularly clean the battery air cooling intake located near the rear seats to prevent debris buildup.
Check tyre pressures monthly, as the low-rolling-resistance tyres are sensitive to pressure and directly impact your daily range.
Flush the brake fluid every two years, remembering that because of regenerative braking, traditional friction brakes are used less and can sometimes seize if not periodically exercised.
Ensure your charging cable is inspected for any signs of heat damage or frayed insulation before every plug-in.
Estimated repair costs if issues arise
While these batteries are robust, if the car's range no longer meets your needs, you might eventually need to budget for a refurbished pack or cell balancing services.
If this component needs attention in the future, it is worth noting that it handles the AC-to-DC conversion for home charging; failure can mean the car is unable to charge at home.
Depending on the car's history, you might eventually need to budget for new shocks and control arm bushings to restore the original ride comfort.
