Unexpectedly Poor Quality
By bostonengine on


2009 Mercedes-Benz C-Class C300 Sport 4MATIC 4dr Sedan AWD (3.0L 6cyl 7A)


We have several MBs in my family. This is probably our 5th MB. I was already impressed with the quality. Reliability was what made this car an Mercedes Benz! However, 2009 that I own is far from reliable.
1. It always had some electrical/electronic issues since I bought every 4-5 months.
2. Road Noise is unbearable. I believe this is a car-specific problem, but Service Department refuses to sees the problem. Whoever gets into my car however, asking me what the noise is coming from.
3. "SRS Malfunction" error message appeared out of nowhere and prevents the use of the car. Let's talk about reliability!
4. Seat is ripped from stitches when the car is only 4 years old.

Best Features

External Design of the car is amazing. It is the best design C series ever had.

Worst Features

You will lose your long-time MB customers if you don't get the reliability and quality back to what it was. How can you prevent a car to start because of an electronic issue!
