EQS 350 - 215kW Single Motor RWD
Electric
Navigate to a quiet area and perform a light braking maneuver from 40km/h; listen for any 'clunking' from the air suspension, as heavy EVs can place significant stress on bushings over time.
Use the MBUX Hyperscreen interface to cycle through every sub-menu for at least 5 minutes, ensuring the screen response is fluid and there is no stuttering or pixelation, which could indicate a maturing software module.
Check the condition of the door handle retraction mechanism by locking and unlocking the vehicle multiple times; listen for any grinding or resistance that might suggest the internal motors are beginning to wear.
Observe the vehicle's interior trim while driving over uneven road surfaces; listen for creaks or rattles, which are sometimes reported in high-tech cabins due to the integration of complex electronics and ambient lighting panels.
Typically requires the first major brake fluid flush and a comprehensive health check of the high-voltage battery management system.
Often the time to inspect the condition of the rear tyres, as the single-motor RWD setup can wear the rear tread faster than front tyres.
Recommended interval for the replacement of the cabin air filtration system and a professional deep-clean of the cooling circuit for the battery pack.
Verify the vehicle has received all over-the-air (OTA) software updates, as these keep the battery management system running at peak efficiency.
Inspect the charging port door and latch mechanism to ensure it seals perfectly against the elements.
Check the tire tread depths across the entire width of the tyre, as EV torque can sometimes lead to uneven inner-shoulder wear.
Ensure the climate control system is operating silently, as any ticking sounds could indicate debris in the cabin fan.
Check the service history to confirm that the brake fluid, which is hygroscopic, has been replaced every two years regardless of low mileage.
Estimated repair costs if issues arise
While very comfortable, air struts can eventually experience minor leaks as the car ages. It is helpful to keep a contingency fund for potential strut replacement or compressor servicing.
Because regenerative braking does most of the heavy lifting, the mechanical brakes can sometimes see less use, leading to surface corrosion. You might eventually need to budget for a full clean and pad refresh to ensure optimal performance.
The EQS relies on a suite of advanced sensors. If you ever need a windscreen replacement, budget for the necessary recalibration of the camera and radar systems to maintain the driver assistance suite.
