60Ah Electric + 647cc Range Extender
Hybrid (Petrol/Electric)
Check the REx engine engagement by letting the battery drop below 6%. | Detail: Ensure the range extender kicks in smoothly without excessive vibration or warning lights on the dash.
Listen for clicking sounds while navigating tight turns. | Detail: It's worth noting that some i3 models have experienced wear in the front drive shafts or suspension bushings, which can manifest as clicking when steering at low speeds.
Test the DC Fast Charging capability at a public station. | Detail: Given the age of the 60Ah models, verifying that the DC port handshakes and charges as expected is a prudent step to ensure the charging control unit is healthy.
Inspect the front 'frunk' area and under the car for any signs of fluid leaks. | Detail: While EVs are generally clean, it's wise to check that the cooling system connections for the battery pack remain dry and free of residue.
Consider a full cooling system flush and check the state of health (SoH) of the high-voltage battery.
Review the condition of the REx engine's oil and spark plugs, as this unit is often neglected in vehicles that run primarily on electric power.
Inspect the suspension components, specifically the front wishbones and shocks, for signs of road fatigue.
Keep the REx engine happy by running a tank of fuel through it every few months to keep the fuel system fresh.
Monitor the 12V battery health, as the i3 is known to throw odd electrical gremlins if the auxiliary battery starts to fade.
Regularly clean the charging port area to prevent debris from causing connection errors.
Check the tyre pressures frequently, as the unique narrow tyres are vital for the vehicle's efficiency and handling.
Ensure cabin air filters are replaced annually to keep the climate control system operating efficiently.
Estimated repair costs if issues arise
Since the 647cc engine is a motorcycle-derived unit, it requires routine oil changes and ignition servicing. If it has been sitting idle for long periods, you might eventually need to budget for fuel system cleaning or injector work.
In cars of this age, it is common to consider the 12V battery a consumable item. Replacing this proactively prevents those frustrating 'no-start' situations that can occur when the main battery is fine but the car's computer fails to wake up.
Depending on the car's history and charging habits, the battery capacity will naturally degrade. It is good practice to have a specialist perform a professional report to manage your expectations on real-world range.
