What Carfax tells you about a used car
A Carfax vehicle history report is a document that collects records about a specific car's past — accidents, repairs, ownership changes, title problems, and service records. Carfax pulls this information from insurance companies, police reports, auto repair shops, dealerships, and state DMV records. The report shows you what happened to the car before you see it, so you can decide whether to buy it or walk away.
The report does not tell you everything. Carfax only knows about events that were reported to one of its data sources. A fender bender that the owner paid for out of pocket, a repair done at an independent shop that did not report to Carfax, or a minor accident that was never reported to insurance — none of these will show up. This is why a clean Carfax report does not may provide a car has no damage history.
You can order a Carfax report directly from Carfax.com, or most used car dealerships and many private sellers will provide one. Some dealerships include it in the listing; others charge a small fee. You can also check Carfax reports on sites like AutoTrader, Cars.com, and Facebook Marketplace, where dealers and some private sellers post them alongside the listing.
Key Takeaways
- Carfax reports show accidents, title issues, ownership history, and service records that were reported to insurance companies, police, or repair shops.
- A clean Carfax does not mean the car has never been damaged — only that no reported accident or service record exists in Carfax's database.
- You can order a report directly from Carfax or view one that a dealer or seller has already posted with the listing.
- The most important sections to check are title status, accident history, and number of previous owners.
What sections appear in a Carfax report
The report is organized into sections that each tell you a different part of the car's story. The title section shows whether the title is clean, salvage, rebuilt, flood-damaged, or branded with another problem. A clean title means the car was not declared a total loss by an insurance company. A salvage or rebuilt title means it was declared a total loss at some point, then repaired and resold — these cars are legal to drive but are worth less and may be harder to insure.
The accident and damage section lists reported accidents, the type of damage (minor, moderate, severe), and whether airbags deployed. This section also shows if the car was reported as a lemon, recalled, or involved in a flood. The service and repair section shows maintenance records reported by dealerships and some independent shops — oil changes, brake work, transmission service, and other repairs. Not all shops report to Carfax, so missing service records do not mean the car was not maintained.
The ownership history shows how many previous owners the car has had and whether it was used as a rental, fleet vehicle, or taxi. The registration and inspection section shows state inspection results and whether the car passed emissions tests. Some states do not report this data to Carfax, so an incomplete registration history does not mean something is wrong.
How to read the title status section
The title status is the first thing to check. A clean title means the car was never declared a total loss by an insurance company. This is the best outcome and the most common for cars that have not been in major accidents.
A salvage title means an insurance company declared the car a total loss — usually because repair costs exceeded 70 to 80 percent of the car's value, though this threshold varies by state. The car was then sold to a salvage yard or auction. A salvage title car is legal to own and drive, but it is worth significantly less than the same model with a clean title, and some insurance companies will not insure it or will charge much higher premiums.
A rebuilt title means a salvage car was repaired and passed a state inspection to be declared roadworthy again. Rebuilt title cars are legal to drive and insure, but they carry the same value penalty as salvage cars and may be harder to resell. A flood title, lemon law buyback, or other brand means the car has a specific problem in its history. Flood-damaged cars are at high risk for electrical and mechanical problems that may not show up when ready.
Understanding the accident and damage history
The accident section lists each reported accident with the date, type of damage (minor, moderate, or severe), and whether airbags deployed. Severity is based on insurance company reports, not on actual repair costs. A "moderate" accident might have been a $3,000 repair or a $15,000 repair — Carfax does not break it down further.
If airbags deployed, the report will note it. Deployed airbags mean the collision was significant enough to trigger the safety system. If the report shows airbags deployed but no accident is listed, it means the airbag deployment was reported separately — sometimes by a repair shop or insurance company — and Carfax recorded it without a matching accident record.
Remember that this section only shows accidents reported to insurance companies or police. A car that was hit in a parking lot and repaired by the owner out of pocket will not appear here. A single-vehicle accident that was never reported to police will not appear. This is why you should also have a mechanic inspect the car in person — they can spot signs of past damage that Carfax does not know about.
What the service history tells you
The service section shows maintenance records reported by dealerships and some independent repair shops. Common entries include oil changes, tire rotations, brake service, transmission fluid changes, and major repairs. A long service history at a dealership suggests the owner maintained the car regularly. Gaps in service records do not necessarily mean the car was neglected — many owners use independent shops that do not report to Carfax, or they do routine maintenance themselves.
If the report shows multiple major repairs in a short time — for example, three transmission services in two years — that can signal a recurring problem. If the report shows no service history at all, it does not mean the car was never serviced; it means no records were reported to Carfax. Ask the seller directly about maintenance and request receipts if they have them.
Ownership history and how many owners matter
The report shows the number of previous owners and the type of ownership — personal, rental, fleet, taxi, or lease. A car with one or two previous owners is common and not a red flag. A car with five or six owners in five years can suggest the car had problems that made owners want to sell it quickly, but it is not definitive.
Rental cars and fleet vehicles typically have higher mileage for their age because they were driven more intensively. Taxi and ride-share cars were driven even more. These cars are not necessarily bad buys, but they may have more wear on the engine, transmission, and suspension than a personal-use car with the same mileage. Lease returns are usually well-maintained because the leasing company inspects them regularly, but they also tend to have higher mileage.
How to use a Carfax report when shopping for a car
Order or view the Carfax report before you go see the car in person. A clean report does not mean you should buy the car, and a report with an accident does not mean you should reject it. Use the report to decide which cars are worth your time and which ones to skip.
If the report shows a salvage or rebuilt title, a major accident with severe damage, or a flood brand, you have a clear decision to make: are you comfortable with that history and the lower resale value? If the report shows minor accidents or routine maintenance, that is normal for a used car. If the report shows no service history but the car is well-maintained when you inspect it, that is also fine.
After you have narrowed down your choices, have a trusted mechanic inspect the car in person. The mechanic can spot signs of past damage, rust, or mechanical problems that Carfax does not know about. Combine the Carfax report with a hands-on inspection and a test drive to make an informed decision.
Frequently Asked Questions
Can I get a Carfax report for free?
Carfax charges a fee to order reports directly from their website, though the price is usually under $30 for a single report. Many used car listings on AutoTrader, Cars.com, and dealer websites include a free Carfax report with the listing. Some dealerships also provide a free report when you visit or inquire about a car.
What if the Carfax report shows an accident but the car looks fine?
An accident report does not tell you how well the car was repaired. A car hit in a minor fender bender might have been repaired perfectly and be completely fine. Have a mechanic inspect the car to check for signs of poor repair work, misaligned panels, or hidden damage. The mechanic can also use a paint depth gauge to detect if panels were repainted.
Does a clean Carfax report mean the car has never been in an accident?
No. A clean Carfax means no accident was reported to insurance companies, police, or repair shops that Carfax tracks. A car can be in an accident and never reported if the owner paid for repairs out of pocket or used an independent shop that does not report to Carfax. This is why a mechanic inspection is essential — they can find evidence of past damage that Carfax does not know about.
What should I do if the title is salvage or rebuilt?
Decide whether you are comfortable with the lower resale value and potential insurance challenges. Contact your insurance company before buying to confirm they will insure a salvage or rebuilt title car and what the premium will be. Have a mechanic inspect the car thoroughly to understand what was damaged and how well it was repaired. These cars can be good deals if the repair was done well, but they require more caution.
How old is the information in a Carfax report?
Carfax updates its database continuously as new records are reported, but there is usually a delay of a few days to a few weeks between when an event happens and when it appears in Carfax. Very recent accidents or service records may not show up yet. If you are buying from a dealer, ask them directly about any recent accidents or repairs not yet on the report.
