GMC Sierra 1500 estimated maintenance cost at 15,000 miles a year
PeriodMilesEstimateBasis
Per year15,000$1,704AAA half-ton crew-cab pickup, 11.36¢/mile
5 years75,000$8,520AAA's own 5-year window

Method: AAA 2025 half-ton crew-cab pickup benchmark: 11.36¢ 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 Sierra 1500-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.
