2015 Mercedes-benz C400 problems
The Mercedes-Benz W205 is the fourth generation of the Mercedes-Benz C-Class which was produced by Daimler AG between 2014 and 2021. The W205 C-Class was preceded by the W204 C-Class and superseded by the W206 C-Class. The fourth-generation C-Class was available in sedan (W205), station wagon/estate (S205), coupe (C205), cabriolet (A205) and long-wheelbase sedan (V205) body styles.
The W205 was the first vehicle to use the all-new Modular Rear Architecture (MRA) platform. The new structure is significantly lighter, using aluminum extensively throughout the body, resulting in a 100 kg (220 lb) weight decrease. According to Mercedes-Benz, the structure is much more rigid than other vehicles in its class.
Development and launch
The car was officially unveiled on 16 December 2013 and debuted at the 2014 North American International Auto Show. W205 production commenced on 4 February 2014 at the Bremen plant. European sales began in March 2014, while the vehicle went on sale in North America in September 2014, and in South Africa in March 2015.
As the Mercedes-Benz CLA-Class (released in April 2013) took the mantle of being the new entry-level sedan in Mercedes' line up of cars, Mercedes decided to make the W205 C-Class larger than its predecessor and more like the W222 S-Class, thus making it a "mini-S-Class".
The W205 included Sport and Luxury trims with 241 hp (180 kW) 2.0-liter turbocharged I4 engine and 329 hp (245 kW) 3.0-liter bi-turbo V6 engine options. Mercedes all-wheel drive 4MATIC is standard across the initial offering. The car is about 3.7 inches (94 mm) longer and 1.7 inches (43 mm) wider than the W204.
Based on the new modular MRA rear-wheel drive platform, it features front axle four-link and rear axle five-link suspension.
