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 2016 Mercedes-benz S550 problems

The 2016 Mercedes-Benz S550 is known for its luxurious features and high-performance engine, but like any vehicle, it can experience certain problems. Here are some common issues reported by owners:

Auxiliary battery failure: This is a common complaint that doesn't seem to be the result of driver error. The auxiliary battery may need to be replaced to resolve the issue.

Blown radiator hoses: This can occur due to wear and tear or lack of maintenance. Regularly checking and replacing radiator hoses can help prevent this issue.

Touchy media system: Some owners have reported issues with the media system being sensitive or difficult to use. This can often be resolved by restarting the system.

Suspension problems: The AIRMATIC self-leveling suspension in the S550 has been noted for issues, including the suspension failing to inflate properly, ride height sensor failure, punctured or leaking air spring, and AIRMATIC compressor failure. These problems can cause additional damage to other parts of the vehicle and may require expensive repairs.

Rear seatbelt malfunction: The seatbelt extender in the back seat might not retract correctly when in use. If the pretensioners in the system deploy in a collision, there's a risk that parts from it could work loose and cause injury to occupants.

Oil leak from turbocharger: 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 extreme circumstances. Affected cars should have a replacement line fitted as part of a recall.

Left front seatbelt: The pretensioner fitted to the front passenger seatbelt that forms a part of the restraint system might not meet specification and therefore not operate as intended in a collision. Affected vehicles are to have the front seatbelt system replaced as a precaution.

Start/stop system malfunction: Due to faulty software installed at the factory, the idle speed can be erratic when coming to a halt and cause the engine to stop when it shouldn't, meaning the start/stop system won't operate as intended. Dealers should update the software to solve the issue.

Front seatbelt fault: The front seatbelts on some models may have been installed incorrectly at the factory and will therefore not protect occupants as they were designed to do in the event of a crash. Affected models should be fixed by the dealer for free.

It is important to note that many of these issues can be prevented or minimized with regular maintenance and adherence to the vehicle's recommended service schedule.
