Overview of popular issues
Recalls list

The Mercedes-Benz C-Class is a series of compact executive cars produced by Mercedes-Benz Group AG. Introduced in 1993 as a replacement for the 190 (W201) range, the C-Class was the smallest model in the marque's line-up until the W168 A-Class arrived in 1997. The C-Class has been available with a "4MATIC" four-wheel drive option since 2002. The third generation (W204) was launched in 2007 while the current W206 generation was launched in 2021.

Initially available in sedan and a station wagon configurations, a fastback coupé (SportCoupé) variant followed and was later renamed to Mercedes-Benz CLC-Class. It remained in production until 2011 when a new W204 C-Class coupé replaced it for the 2012 model year.

First generation (W202; 1993)

In October 1986, three years into Mercedes-Benz 190 (W201)'s production run, work began on a successor. Design work began in 1987, with the final design by Murat Günak selected in 1989 and the production design by Olivier Boulay delayed in January 1990, finally being patented on 19 December 1990. Rough prototypes went into testing in 1989, with first production design prototypes commencing trial in 1990. In May 1993, the first generation W202 C-Class was introduced as a replacement for the 190. The first C-Class (W202) sedan was manufactured on 1 June 1993. The C-Class sedan was the company's entry-level model up until 1997 when Mercedes launched the A-Class. Styling themes were carried over from the previous W201 series, but the new series had a smoother and rounder design than the last generation of compact Mercedes, with styling cues from the W124 E-Class (short, high trunk and taller tail lights), W140 S-Class (front end), and R129 SL-Class (headlights).

During the 1996 and 1997 Formula 1 season, the C36 AMG served as the sport's Safety Car.

Common 2017 Mercedes-benz C300 problems

Based on complaints from owners of the Mercedes-Benz C300 2017, several common problems have been reported:

Squeaky Brakes: There are reports of brakes beginning to squeak halfway through their usable life due to deformed rotors from the size and material used in the brake pads. This leads to changing brake rotors every time the pads are worn down, affecting models prior to 2012.

Oil Leak on Cylinder Heads: Misdiagnosed as leaking valve covers, this problem stems from plastic expansion plugs used in models between 2008 and 2012. These plugs need replacement every 60,000 miles to prevent engine oil leaks.

Vibrations in the Center Floor: Drivers have reported vibrations coming through the center floor caused by cracked driveshaft flex discs, leading to extreme vibrations. Immediate repair is necessary to avoid transmission damage, affecting models prior to 2012.
