Carfax
Carfax is a commercial vehicle history reporting service that compiles data on used cars, light trucks, and SUVs sold in the United States and Canada. A Carfax Vehicle History Report is generated using a vehicle’s 17-digit Vehicle Identification Number (VIN) and pulls information from thousands of sources, including state motor vehicle departments (DMVs), insurance companies, auto auctions, service and repair shops, rental agencies, and law enforcement. The report is designed to help buyers, sellers, and dealers understand a vehicle’s documented past before money changes hands.
A typical Carfax report includes:
- Title history and any branded titles (salvage, flood, rebuilt, lemon law buyback)
- Reported accidents and structural damage
- Odometer readings over time, with rollback alerts
- Number of previous owners and how the vehicle was used (personal, fleet, rental, lease)
- Service and maintenance records reported by participating shops
- Open safety recalls, which Carfax pulls from NHTSA’s recall database
For example, a shopper considering a 2019 Honda Civic can enter the VIN and see whether the car has a clean title in all 50 states, whether any airbag or fuel pump recalls remain unrepaired, and whether odometer readings have increased consistently. A second example: a 2016 Ford F-150 flagged with a “flood damage” title brand from a Gulf Coast state is an immediate red flag, even if the truck looks clean on the lot.
Used car shoppers should care about Carfax for several reasons. First, it helps identify curbstoned or title-washed vehicles that may have been totaled in one state and retitled in another. Second, it surfaces open recalls so buyers can cross-check with NHTSA’s free VIN lookup at NHTSA.gov before purchase. Third, service history can hint at whether a vehicle was maintained according to the manufacturer’s schedule, which affects long-term reliability and resale value. However, Carfax is not a substitute for a pre-purchase inspection by a qualified mechanic, and it cannot report damage or repairs that were never documented. Buyers should also consult NHTSA for complaints and NCAP crash test ratings, and EPA fuel economy data at FuelEconomy.gov, to build a complete picture of any used vehicle.
