2018 Mercedes-benz S450 problems
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 2018 Mercedes-benz S450 problems
The Mercedes-Benz S450 2018 is generally considered to be a reliable vehicle, with most owners reporting only the usual issues such as oil changes, brake replacements, and tire rotations in the first 35,000 miles. However, there are a few common problems that some owners have reported:
- Oil-in-the-wiring-harness issue: Some owners have reported an issue with oil getting into the wiring harness, which can cause problems with the electrical system. This issue is reportedly being addressed with the required pigtails.
- Rough stop-start system: Some owners have reported that the stop-start system on the V6 engine can be rough and less polished than on other engines. This can be particularly noticeable at stoplights.
- Lack of advanced technology: The S450 2018 may not have as many advanced technology features as some of its competitors, such as rear-wheel steering, active suspension, and engine-off coasting.
- Energizing Comfort feature: Some owners have reported that the Energizing Comfort feature, which is designed to keep drivers perky behind the wheel, can be a bit of a gimmick. It primarily engages the massaging seats, cranks up the air-conditioning perfumer, and plays a Muzak-like playlist.
Overall, the Mercedes-Benz S450 2018 is generally considered to be a reliable vehicle, with most owners reporting only minor issues in the first 35,000 miles. However, there are a few common problems that some owners have reported, including issues with the wiring harness, rough stop-start system, lack of advanced technology, and the Energizing Comfort feature.
