On the 2021-2025 Mercedes-Benz Mercedes-Maybach S-Class, the E-Active Body Control suspension on the Maybach S-Class gradually loses its signature "magic carpet" ride quality over time. The hydraulic fluid in the active suspension actuators degrades, and the system becomes less responsive to road imperfections. Owners notice increased road harshness after 20,000-30,000 miles.

Common Symptoms

  • Ride quality noticeably harsher than when new
  • Road imperfections felt more through cabin
  • Body lean increased in corners
  • Suspension system warning light on dashboard

How to Fix

Have the E-Active Body Control hydraulic fluid flushed and replaced at a Mercedes dealer. The system requires a specific hydraulic fluid and dealer-level calibration after service. If individual actuators show reduced response, they can be replaced individually.

Owner tips & cautions

  • TipRequest a hydraulic fluid flush at 30,000 miles even if not scheduled. The ride quality improvement is immediately noticeable. Budget $800-$1,200 for the fluid service at a dealer.
Typical repair cost:$800 - $5,000

On the 2021-2025 Mercedes-Benz Mercedes-Maybach S-Class, the optional Air Balance cabin fragrance system stops dispensing scent or dispenses continuously at maximum intensity. The fragrance vial mechanism jams in the open or closed position, and the MBUX interface shows the system as active when it is not functioning.

Common Symptoms

  • No fragrance despite system showing active
  • Overwhelming fragrance intensity that cannot be reduced
  • MBUX fragrance controls unresponsive
  • Clicking noise from center console area

How to Fix

Remove and reseat the fragrance vial, ensuring it clicks into place properly. Clean the dispensing mechanism with compressed air. If the motorized vial holder is jammed, a dealer can replace the fragrance module — it is located behind the center console trim. Use only Mercedes-branded fragrance vials to prevent compatibility issues.

On the 2021-2025 Mercedes-Benz Mercedes-Maybach S-Class, the rear seat MBUX entertainment screens in the Maybach S-Class freeze or become unresponsive during use, requiring a full system reboot to recover. The dual rear screens share a processing unit that becomes overwhelmed when both screens run different media sources simultaneously.

This issue also affects: Mercedes-Benz CLS-Class, Mercedes-Benz G-Class, Mercedes-Benz GLB

Common Symptoms

  • Rear screen frozen on last displayed content
  • Touchscreen input unresponsive on rear screens
  • Audio continues but video freezes
  • Both rear screens crash simultaneously

How to Fix

Reboot the rear entertainment system by holding both rear screen power buttons for 10 seconds. Install the latest MBUX OTA update which includes rear entertainment stability improvements. If freezing persists, the rear entertainment processing unit may need replacement at a dealer.

Owner tips & cautions

  • TipAvoid running different streaming apps on both rear screens simultaneously — this is what triggers most freezes. Use the same source on both or keep one screen off. OTA updates have improved stability significantly.
