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 2012 Mercedes-benz C350 problems

The Mercedes-Benz C350, a luxury compact car produced between 2007 and 2014, has been reported to have several common issues that owners may encounter. Here are some of the problems found in the 2012 C350 model, based on the complaints of owners.

Engine Problems: Some 2012 C350 owners have reported issues with the engine, including problems with the timing chain and oil leaks. These issues can be expensive to repair or require a full engine replacement.
Transmission Problems: Some owners have reported problems with the automatic transmission, including delayed shifting and rough shifting. These issues can be expensive to repair or require a full transmission replacement.
Suspension Problems: Some Mercedes W204s have had issues with their suspension, including problems with the shocks and struts. These issues can cause a rough ride or uneven tire wear.
Electrical Problems: Some Mercedes W204 owners have reported issues with the electrical system, including problems with the battery, alternator, and various sensors. These issues can cause the car to stall or not start and can be expensive to repair.
Rust: The Mercedes W204 is known to have issues with rust, particularly on the rear quarter panels and doors.
Check Engine Light: Some 2012 C350 owners have reported that the check engine light has been coming on and off, despite several visits to the dealership for inspection. The car also idles rough, but the dealership could not find a problem with it.
Accessory Knobs Inoperable: The 2010 Mercedes-Benz C350 has the most overall complaints, and the most-reported problem is also with the 2010 model for accessory knobs inoperable. The average cost to fix this problem is $5,300, with an average mileage of 74,000 mi.

Fuel Injector Problems: Blue Efficiency diesel models can develop fuel injector problems, which will cause hesitant acceleration and uneven running.
Headlamps: Headlamps can be a problem, with moisture and condensation building up inside. The post-2012 facelift lights are less vulnerable in this respect.
Door Mirrors: The door mirrors can be problematic, with noisy folding and adjusting motors and the integral indicator repeaters falling out of sync with the main units. They’re expensive to replace (as much as £500 each) so check them carefully.

Comand Infotainment System: The Comand infotainment system can be fragile, so make sure that all functions are working properly.
Alloy Wheels: There have also been reports of alloy wheels corroding and flaking.
Seats: The seats, especially when fitted with part-leather trim, are prone to bursting their stitches, so check carefully around the seat bases.

These issues can be costly to repair and can affect the overall performance and reliability of the vehicle. Regular maintenance and prompt repairs can help prevent problems from developing or becoming more serious. It's important to have a thorough inspection done by a qualified mechanic before making a purchase to identify any potential issues
