EQB 350 4MATIC (66.5 kWh) - Top-spec dual motor, AWD
Electric
While driving on varied road surfaces, listen closely for any rattles or clonks from the rear suspension. | Note: Some owners find the rear multi-link setup can become vocal over time, so ensure the ride feels compliant rather than jarring.
Check this by navigating the MBUX infotainment screen extensively while stationary. | Note: The dual-screen setup is feature-rich, but it is worth ensuring the interface remains snappy and responsive, as occasional software bugs can occur in earlier production units.
Check this by inspecting the tyres for uneven wear across the tread. | Note: Given the EQB 350's instant torque and AWD nature, it is common to consider that heavy-footed driving may lead to accelerated tyre wear, especially on the front axle.
While charging, observe the charge port door and locking mechanism for smooth operation. | Note: In cars of this age, it is worth confirming the port seals properly to protect against moisture, a frequent consideration in New Zealand's wetter climates.
Usually marks the first significant inspection of the high-voltage cooling system and cabin air filtration.
A common point where proactive inspection of the suspension bushings and alignment is recommended to ensure optimal tyre longevity.
Typically when a comprehensive check of the battery health report and motor mounting integrity should be prioritised.
Ensure the brake fluid has been flushed every two years, as this is crucial for the regenerative braking transition.
Keep up to date with the digital service history via the Mercedes-Benz portal to maintain the warranty integrity.
Regularly clean the charging port area to prevent debris buildup that could impact the charging cable connection.
Verify that the MBUX system has received the latest over-the-air updates to improve energy management and interface stability.
Check the condition of the cabin air filter annually, especially if the vehicle is frequently driven on dusty rural roads.
Estimated repair costs if issues arise
Depending on the car's history and road conditions, you might eventually need to budget for new bushings or linkages if the ride quality begins to deteriorate.
If this component needs attention in the future, remember that the EQB requires tyres designed for heavy electric vehicles to maintain range and noise suppression.
Even in electric vehicles, the 12V battery can fade. It is common to consider replacing this every 4-5 years to prevent unexpected system errors.
