Perform a series of gentle and firm stops to check for any shudder or uneven brake feel, as some owners have noted that the regenerative braking system combined with traditional friction brakes can feel inconsistent if the discs have surface oxidation from sitting.
Navigate through several tight corners and listen carefully for any clunking or rattles from the suspension; as a RWD vehicle with a firm setup, some units may exhibit early signs of bushing wear on NZ’s rougher chip-seal roads.
Cycle through the infotainment menus while parked to ensure the touchscreen responsiveness is adequate, as early software versions in the MG4 have occasionally been reported as laggy during initial start-up sequences.
Check the condition of the charging port door and its seal, ensuring it closes flush and firmly, as this component is frequently used and should be inspected for any alignment issues or signs of moisture ingress.
Initial safety inspection and cabin air filter replacement.
Brake fluid flush recommended due to the heavy reliance on regenerative braking.
Coolant system check for the battery thermal management system.
Comprehensive check of suspension components and battery health report.
Keep up with the annual scheduled servicing at an MG-certified dealer to ensure the battery warranty remains fully valid.
Periodically clear the charging port area of any leaves or debris to prevent moisture buildup.
Monitor tyre pressures regularly, as the MG4 is sensitive to pressure variations which can affect both range and handling.
Keep the software updated; your local dealer can assist with OTA or manual firmware updates to improve system stability.
Use a reputable home wall-box charger rather than relying exclusively on high-speed DC charging to help maintain long-term battery health.
Estimated repair costs if issues arise
Because the regenerative braking does most of the heavy lifting, the physical brake pads can sometimes seize or corrode over time from lack of use. It is wise to plan for a potential service to clean and lubricate the sliders or replace pads earlier than expected.
If you drive on challenging rural roads, you might eventually need to budget for the replacement of sway bar links or control arm bushings as they naturally age. It is a common wear item that ensures your MG4 keeps its crisp handling feel.
