Is the Mercedes-Benz C-Class high maintenance?
By CarWhere Research · Updated
Mercedes-Benz doesn't publish service prices, so we don't put a dollar figure on the C-Class (AAA's mainstream medium sedan average, for context, is $1,787 a year). NHTSA holds 5,255 owner complaints for the C-Class, with 1 model year flagged in our years-to-avoid analysis; we don't have the sales data to turn that into a per-1,000 rate.

C-Class maintenance cost: 5 and 10 years
Mercedes-Benz doesn't publish service prices, and AAA's benchmark is built from top-selling mainstream models, so applying it to a Mercedes-Benz would understate the cost. We don't put a dollar figure on it. For scale only: AAA's 2025 benchmark for mainstream medium sedan models is $1,787 a year (11.91¢ a mile), and the all-vehicle average is $1,656. The best predictors of what you'll spend are the factory schedule below, the length of any included maintenance and the complaint record.
How the verdict is set: Two inputs. Cost: the estimate against AAA's $1,656 all-vehicle average (more than 3% under counts in the car's favor, more than 3% over against it). Complaints: NHTSA owner complaints per 1,000 sold against the median of every model in our study (0.48); well under the median helps, well over hurts, roughly double or more hurts twice as much. Both low = "No"; both high = "Yes". Models without a dollar estimate get no verdict.
