This year drew an ordinary 76 complaints for a Mercedes-Benz C-Class — the model's median is 280. What they were about is the unusual part: 47.4% of them mention assist, against 18.2% across the model's other years.

What the complaints were about
- assist — 47.4% of this year's complaints, against 18.2% across the model's other years (2.6×). Owners wrote it as: assist, blind, spot, active.

- safety — 39.5% of this year's complaints, against 12.4% across the model's other years (3.2×).

How this was worked out
Every year of the Mercedes-Benz C-Class was compared against its own history rather than against other cars, which removes popularity and age from the answer — a common car draws more complaints at equal reliability, and an older one has had longer to accumulate them. A year is flagged when it drew at least 2.5× this model's median and at least 50 complaints.
This is a fault record, not a review. Nobody files a federal complaint to say the car was fine, so it shows what tends to go wrong — not whether owners liked it, and not whether it is a good car.
