Mercedes-benz C204.9 problems

Common Mercedes-benz C204.9 problems

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-Benz C204.9 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.

Another common problem with the Mercedes-Benz C204.9 is 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 are also a common issue with the Mercedes-Benz C204.9. Some cars have had issues with their suspension, including problems with the shocks and struts. These issues can cause a rough ride or uneven tire wear.

Engine problems are also a concern for some Mercedes-Benz C204.9 owners. Some cars have had issues with the timing chain and oil leaks. These issues can be expensive to repair or require a full engine replacement.

Additionally, the Mercedes-Benz C204.9 is known to have issues with rust, particularly on the rear quarter panels and doors. This can be a significant issue for a used car, as it can lead to more serious problems down the line.

Finally, the seats, especially when fitted with part-leather trim, are prone to bursting their stitches, so check carefully around the seat bases. Headlamps can be a problem; they seem to be prone to letting moisture and condensation in, although the post-2012 facelift lights are less vulnerable in this respect. Blue Efficiency diesel models can develop fuel injector problems, which will cause hesitant acceleration and uneven running. A clunking noise from the optional seven-speed automatic gearbox is usually due to a faulty transmission valve, which can seriously damage the gearbox and cost as much as £3000 to rectify. There were recalls for leaking fuel filters and power steering lines, incorrect brake discs, faulty Active Body Control sensors and engine management systems. Check if the car you’re looking at was affected and, if it was, that the work has been done.

Regular maintenance and prompt repairs can help prevent these 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.
