Costs are national estimates built from book labor hours × a shop door rate (from BLS metro technician wages, national median since no buyer location is collected on this site today) plus a parts-price range. They are not this vehicle's actual repair history and don't account for your location, shop type, or mileage. A system with more complaints on this vehicle isn't necessarily the one that will cost more to fix — this shows what repairs in that system typically run, not which one you'll need. See Methodology for the full model.
