2025 Mercedes-Benz S500 Rattling Noise

The brakes may begin to squeak at about the 50 percent wear point. This is due to the size and material used for the brake pads and rotors. The brake rotor surfaces become uneven, causing a lip to form at the outer edge. This will generally require replacement of the rotors when the pads are worn (pad life varies depending on driving style and terrain).

Some Mercedes-Benz S500 owners report experiencing front suspension noise, particularly from the driver's side steering components, which may indicate suspension issues. These noises can stem from wear and tear, potentially leading to abnormal tire wear, alignment problems, and excessive noise while driving. Additionally, some owners report slight steering vibration, particularly at high speeds, which could be attributed to unbalanced wheels or worn control arm bushings, both of which can cause significant vibrations in the steering wheel. Moreover, noticeable noise during entry and exit may be linked to suspension components or stabilizer links. To address these concerns, it is advisable for owners to have their suspension system inspected by a qualified mechanic, check wheel balance and alignment, and consider replacing worn control arm bushings. Prompt attention to these issues is essential for maintaining the performance and comfort of the Mercedes-Benz S500.
