The Mercedes-Benz S-Class, formerly known as Sonderklasse (German for "special class", abbreviated as "S-Klasse"), is a series of full-sized luxury sedans, limousines and armored sedans produced by the German automaker Mercedes-Benz. The S-Class is the designation for top-of-the-line Mercedes-Benz models and was officially introduced in 1972 with the W116, and has remained in use ever since. The S-Class is one of the flagship vehicles for Mercedes-Benz.

The S-Class has debuted many of the company's latest innovations, including drivetrain technologies, interior features, and safety systems (such as the first seatbelt pretensioners). The S-Class has ranked as the world's best-selling luxury sedan. In automotive terms, Sonderklasse refers to "a specially outfitted car." Although used colloquially for decades, following its official application in 1972, six generations of officially named S-Klasse sedans have been produced.

In 1981, the two-door, four-seat S-Class, designated as SEC, was introduced, sharing the petrol V8 engines with its four-door version, W126. After the introduction of a new nomenclature scheme, SEC was simply renamed as S-Class Coupé. For the 1996 model year, the coupé was separated from the S-Class line and named as new CL-Class (in line with other two-door models: CLK, SL, and SLK); however, the CL-Class was reintegrated into the S-Class model line (same with CLK becoming E-Class Coupé and Cabriolet). The first-ever S-Class convertible since 1972, internally named A217, was introduced and became a one-generation model only. After the end of W222 production in 2020, the successors to the C217 coupé and A217 convertible are not planned, citing the low demand for those models and stronger demand for SUV models.

Common Mercedes-benz S450 problems

The Mercedes-Benz S450 (W2220) is a luxury sedan known for its refined performance and advanced technology. However, like any vehicle, it is not immune to issues and common problems reported by owners.

  • Oil Feed Pipe Leak: The oil feed pipe going to the turbocharger can develop a leak, potentially leaking oil on to hot engine components that could lead to a fire in the engine bay. This issue is more prevalent in higher mileage vehicles and may require immediate attention to prevent further damage.
  • Electrical Issues: Some owners have reported various electrical issues, such as malfunctioning sensors, non-responsive controls, and warning lights on the dashboard. These issues can be intermittent and difficult to diagnose, often requiring a visit to a dealership or a specialist mechanic.
  • Recalls: The Mercedes-Benz S450 has had several recalls, with the most common being the Emergency Call System Transmitting Incorrect Location in an Emergency. This issue can be potentially dangerous in the event of an accident or other emergency, and owners are advised to have the recall performed as soon as possible.
  • Maintenance Costs: While the Mercedes-Benz S450 is known for its luxury features and advanced technology, these come with a higher cost of ownership. Regular maintenance, such as oil changes, brake service, and tire replacement, can be more expensive compared to other vehicles in its class.
  • Transmission Issues: Some owners have reported transmission-related issues, such as rough shifting, delayed engagement, and slipping. These issues may require a transmission service or replacement, which can be costly.
  • Wiring Harness Oil Contamination: There have been reports of oil contamination in the wiring harness, which can lead to various electrical issues. This problem is typically addressed with the installation of required pigtails to prevent further damage.

In summary, while the Mercedes-Benz S450 is a luxurious and technologically advanced vehicle, it is not without its common problems. Issues such as air suspension failures, oil feed pipe leaks, electrical problems, recalls, high maintenance costs, transmission issues, and wiring harness oil contamination have been reported by owners. Regular maintenance and prompt attention to any issues can help ensure a reliable and enjoyable ownership experience.
