2021 Mercedes-benz Cls450 problems
The C257 Mercedes-Benz CLS is the third generation of the CLS range of four-door sedan, and was launched in 2018 as the successor to the Mercedes-Benz CLS (C218). It is only available as a sedan, with no plans to introduce a Shooting Brake variant in the near future. It is based heavily on the E-Class (W213).
Development and launch
Information on the C257 CLS was released online on 29 November 2017, with a public unveiling at the Detroit Auto Show in January 2018.
The new CLS uses a four-link front suspension and a five-link rear suspension and comes in rear-wheel drive and all-wheel drive (4MATIC) configurations. CLS 53 4MATIC+ models utilise variable all-wheel drive, allowing for torque distribution between the front and rear axles. An electric motor is used to boost power output by 16 kW (21 hp) and 249 N⋅m (184 lb⋅ft), and also powers the on-board 48-volt system.
The CLS is also now a five-seater car, instead of being a four-seater as with the previous two generations.

Common 2021 Mercedes-benz Cls450 problems
The 2021 Mercedes-Benz CLS450 is a stylish and powerful luxury sedan that competes with the Audi A7, BMW 8-Series, Jaguar XF, Porsche Panamera, and even Mercedes’ own GT 4-Door Coupe. However, as with any vehicle, there are potential issues that owners may encounter.
One common problem reported for the Mercedes-Benz CLS-Class is related to the 12-Volt battery in the trunk, which may not be properly secured. In the event of a crash, this can cause electrical connection failure, disabling various safety features including the emergency call (eCall) system, electric seat adjustment, hazard warning lights, and automatic door locks.
Another potential issue is related to the seat position switches. Mercedes-Benz USA is recalling certain 2021 C-Class, E-Class, E-Class Coupe and Convertible, GLC, CLS, and other models due to a problem with the seat position switches, which may not function properly. Dealers will replace the seat position switches free of charge.
It is important to note that the 2021 Mercedes-Benz CLS450 has not had any reported problems or recalls specifically related to its engine, transmission, or suspension systems. However, as with any vehicle, regular maintenance and inspections are crucial to ensure proper operation and longevity.
In summary, while the 2021 Mercedes-Benz CLS450 is a powerful and luxurious vehicle, potential issues related to the 12-Volt battery and seat position switches may affect certain models. Owners are advised to stay informed and contact Mercedes-Benz USA customer service for more information.
