EQB 350 4MATIC (66.5 kWh) - High-performance dual motor, AWD
Electric
Check this by inspecting the high-voltage charging port door for any signs of misalignment or stiffness, as consistent operation is key to your charging experience in NZ conditions.
While driving, pay close attention to the MBUX infotainment screen responsiveness; ensure the touch interface feels snappy as these systems are feature-rich and rely on smooth software performance.
Test this by finding a quiet stretch of road to listen for any wind noise around the frameless door seals or B-pillars, which can occasionally occur on vehicles with this design profile.
Check this by observing the regenerative braking transition; ensure the hand-off between regenerative and friction braking feels consistent and predictable under varied braking pressures.
Routine cabin air filter change and comprehensive battery health report check.
Brake fluid flush and inspection of cooling system lines for the high-voltage battery thermal management.
Recommended inspection of the drive unit mounts and cooling fan operation for the battery pack.
Full system diagnostics update and detailed inspection of the AWD drivetrain components.
Keep your charging cable and home wall-box connections clean and free of debris to ensure efficient power transfer.
Schedule an annual software update check with your local Mercedes-Benz dealer to keep your MBUX system and battery management software current.
Monitor your tyre pressures regularly, as the heavy battery pack makes the EQB sensitive to correct inflation for optimal range and tyre longevity.
Use the pre-entry climate control feature while plugged in to preserve your battery range during those chilly NZ winter mornings.
Keep a record of your DC fast-charging sessions, as regular high-speed charging is part of the vehicle's history which can be useful for future servicing.
Estimated repair costs if issues arise
Due to the torque of the dual-motor setup and the vehicle's weight, you might eventually need to budget for high-load rated EV tyres, which tend to wear slightly faster than those on lighter vehicles.
Even in an EV, a 12V battery powers the electronics. If the system signals a warning, it's common to consider replacement to ensure the car boots up correctly.
Because regenerative braking does most of the heavy lifting, the friction brakes are used less. Occasionally, you may need to budget for a service to ensure the sliding pins and rotors remain free from surface corrosion.
