Is 16 complaints a lot? They were filed between 2011 and 2026, roughly 1 a year, which is fewer 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 2010 has 16 complaints on file, fewer than the 2014 (24). Of the 5 model years of the Mercedes-Benz S550 we cover, the 2015 has the most (41). Older model years have had longer to collect complaints.
