Mercedes-Benz S55 AMG Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Mercedes-Benz S55 AMG

The active body control system can leak fluid from numerous areas, including the tandem pump, hydraulic lines, struts, and/or seals. If it is not repaired, the vehicle ride height could drop too low and cause damage to the undercarriage.

The door for the vanity mirror (or the frame for the door) can break; due to a redesign, the mirror "cassette" will need replacement.

The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern.

Also, I had SRS lamp came up. So total was almost $5000. I am surprised that it is their flagship model but it starts to fall apart after only 64K miles.
