Estimated repair costs if issues arise

Given the performance capabilities and weight of the S 580, the brakes are high-performance units. Depending on your driving style, you might eventually need to budget for high-quality pads and rotors to maintain safe stopping power.
Modern luxury vehicles rely heavily on complex electronic modules. If a component of the MBUX system requires attention outside of warranty, it is worth planning for a professional diagnostic and component replacement cost.
