CX-30 maintenance cost: 5 and 10 years
| Period | Miles | Estimate | Basis |
|---|---|---|---|
| Per year | 15,000 | $1,619 | AAA subcompact SUV, 10.79¢/mile |
| 5 years | 75,000 | $8,095 | AAA's own 5-year window |
| 10 years (floor) | 150,000 | $16,190+ | AAA's 5-year per-mile rate, extended in a straight line |
Method: AAA 2025 subcompact SUV benchmark: 10.79¢ a mile × 15,000 miles a year. Covers scheduled maintenance, wear-item repairs, one set of tires and an extended warranty over 5 years. A category average, not a CX-30-specific quote. The 10-year figure is a floor: it doesn't add the larger age-related repairs (and later scheduled items such as spark plugs or coolant) that come after year 5.
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.
