Is 215 complaints a lot? They were filed between 2016 and 2026, roughly 22 a year, which is more than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.

How does it compare with other years? The 2017 has 215 complaints on file, fewer than the 2016 (285) and more than the 2019 (35). Of the 11 model years of the Mercedes-Benz C300 we cover, the 2011 has the most (478). Older model years have had longer to collect complaints.
