EQB 300 4MATIC (66.5 kWh) - Dual motor, AWD
Electric
During low-speed maneuvers in a quiet area, listen closely for any unusual clicks or clunks from the front drivetrain, as dual-motor setups can occasionally show premature wear in CV joints if driven aggressively.
Cycle through the MBUX infotainment screen and test the voice commands; ensuring the software responsiveness is fluid is vital, as system glitches are occasionally noted in the facelift's high-tech cockpit.
While parked on a flat surface, inspect the alignment of the charging port door and the surrounding panel gaps, as any resistance when opening or closing could indicate a minor alignment issue common in mass-produced EV chassis.
When transitioning from regenerative braking to friction braking, observe if the pedal feel is consistent; any hesitation or 'sponginess' should be noted for a technician to verify the brake-by-wire system calibration.
Initial comprehensive software update and inspection of the high-voltage cable routing.
Cabin air filtration refresh and thorough assessment of the heat pump efficiency.
Brake fluid replacement and a specialized diagnostic report on battery health (SOH).
Potential consideration for secondary coolant loop flush to maintain optimal thermal management.
Keep the charging port area free of debris to ensure a clean connection every time you plug in.
Regularly monitor your tyre pressures, as EVs are heavier and benefit from correct inflation for both efficiency and tread longevity.
Update your MBUX software via Over-the-Air updates when prompted to keep the digital experience smooth.
Occasionally use the friction brakes firmly to prevent surface corrosion, as the regenerative system often does the heavy lifting.
Schedule an annual 'EV health check' with an authorized service centre to monitor cell balance and thermal management systems.
Estimated repair costs if issues arise
Future Budget Planning: The heat pump is critical for your range efficiency in NZ winters. If the system loses efficiency over time due to refrigerant leaks or sensor wear, you might eventually need to budget for a professional leak test and recharge.
Future Budget Planning: Given the EQB's substantial weight compared to combustion cars, suspension bushings carry a heavy load. As the car ages, you might eventually need to budget for refreshing these components to maintain that signature Mercedes ride comfort.
Future Budget Planning: High-torque electric motors can be quite firm on rubber. Depending on your driving style, it is common to consider that the EQB may require premium EV-rated tyres more frequently than a standard petrol SUV.
