The 2008 Mercedes SL550 is well-known for its problematic proprietary hydraulic suspension system, also known as the "body control system," which is prone to fluid leaks and malfunctions. Many consumers have reported issues with the SL550's body control system, with failures typically occurring around the 50,000-mile mark. Problems with leaks from the tandem pump, hydraulic lines, struts, and seals have been common. Additionally, there have been complaints about faulty trunk and door closures due to leaks in the pneumatic system, leading to difficulties in fully closing these parts and intermittent operation of the door locks. Owners have often encountered issues with the PSE pump burning out, requiring a costly replacement of over $500. Another significant concern for this Mercedes is the need for camshaft adjuster solenoid replacement, resulting in the triggering of the P0015 code and illumination of the "check engine" light, especially in new vehicles under warranty.

There are no particular problems with the 2008 Mercedes SL550, but because of its age, it's possible there will be engine or transmission issues. Rust or corrosion could have occurred over time. It's important to inspect the brake lines and other fluid lines for signs of dry rot and leaks. Brake pads will probably need to be changed, and you should check the tires for signs of aging and deterioration. Ensure that the oil and oil pump are examined for any deterioration in the lines and cracks in the pan. It's also possible that there are frayed or damaged wires and blown fuses causing electrical issues throughout the vehicle.
