The Mercedes-Benz C204.9, also known as the C-Class, is a popular luxury compact car that was produced from 2007 to 2014. While it is generally known for its high-quality engineering and strong performance, there are a few issues that some owners have reported over the years.

One of the most common problems with the Mercedes W204 is electrical issues. Some owners have reported 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.

The Mercedes W204 is also known to have issues with rust, particularly on the rear quarter panels and doors.
