Ascent maintenance cost: 5 and 10 years

Subaru Ascent estimated maintenance cost at 15,000 miles a year
PeriodMilesEstimateBasis
Per year15,000$1,769AAA medium SUV (4WD), 11.79¢/mile
5 years75,000$8,845AAA's own 5-year window
10 years (floor)150,000$17,690+AAA's 5-year per-mile rate, extended in a straight line

Method: AAA 2025 medium SUV (4WD) benchmark: 11.79¢ 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 Ascent-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.

How the Ascent compares in its AAA category (medium SUV (4WD))

Same AAA category means the same dollar benchmark, so the complaint rate is what separates them. Luxury models aren't priced.
