Carfax is a complete joke! I have a vehicle that was involved in a major accident almost two years ago. Over 14k in damage. Police report, Insurance paid, Reputable local body shop. Yet when I checked the vin via Carfax it still doesn't show any accidents. About the only thing it is good for is verifying mileage and ownership changes. I checked other vehicles that friends owned that were involved in accidents and found the same results.
