What a vehicle history check shows you
A vehicle history check is a report that pulls together records about a car's past — where it's been registered, whether it's been in accidents, if the title is clean, and whether it's been recalled. The report doesn't tell you if the engine runs or if the brakes work; it tells you what happened to the car in official records. You order the report using the car's Vehicle Identification Number (VIN), a 17-character code unique to that vehicle.
The most common reports come from Carfax and AutoCheck, two companies that buy data from insurance companies, police reports, DMV records, and repair shops. When you run a VIN through either service, you get back a timeline of reported events — title transfers, accident claims, service records from participating shops, and whether the car was ever branded as a salvage or flood vehicle. Some information appears on one report but not the other, because the companies don't have access to the same data sources.
What you won't see in a history report: unreported accidents, mechanical problems, or maintenance that happened at independent shops that don't report to either company. A clean report doesn't mean the car is in perfect condition. It means nothing bad was officially recorded.
Key Takeaways
- Vehicle history reports pull data from insurance claims, DMV records, and repair shops, but only show events that were officially reported.
- Carfax and AutoCheck are the two main sources, and they don't always have the same information about the same car.
- A clean history report doesn't may provide the car is in good condition — it only means no major accidents or title problems were recorded.
- You can order a report before you make an offer, and many dealerships provide one as part of their listing.
What title problems look like in a history report
A title brand is a permanent mark on a car's ownership record that signals something serious happened. The most common brands are salvage (the car was declared a total loss by an insurance company), flood (the car was damaged by water), and lemon law buyback (the manufacturer repurchased it because of repeated defects). Some states also use brands for rebuilt, reconstructed, or branded titles — the exact names vary by state.
If a car has a salvage title, it means an insurance company paid out a claim for damage that exceeded a certain percentage of the car's value (usually 70 to 80 percent, depending on the state). The car may have been repaired and is now being resold, but the title will always carry that mark. A flood-branded car has been submerged or exposed to significant water damage. These cars can develop electrical and mechanical problems years after the water damage, even if they were dried out and repaired.
A lemon law buyback means the manufacturer took the car back from the original owner because it had defects that couldn't be fixed after multiple repair attempts. The car was then resold, usually at auction. You should be cautious about buying any car with a branded title, because the problems that triggered the brand can resurface.
Accident and damage records in a history report
When an insurance company pays a claim for an accident, that claim gets reported to Carfax and AutoCheck. The report will show the date of the accident, the type of damage (collision, comprehensive, etc.), and sometimes the amount paid. However, not every accident appears in a history report. If the owner paid out of pocket instead of filing a claim, or if the accident was minor and never reported to insurance, it won't show up.
The report may also include service records from repair shops that participate in the reporting system. If a shop replaced a bumper, fixed frame damage, or repaired a transmission, and that shop reports to Carfax or AutoCheck, the work will appear on the timeline. Again, work done at independent shops or by the owner usually doesn't appear.
Multiple accidents or a pattern of damage claims can be a red flag. A single accident that was repaired professionally is less concerning than three accidents in two years, which might suggest the car is being driven unsafely or has underlying structural problems.
Recall information and service bulletins
A history report includes any recalls issued by the manufacturer for that vehicle. Recalls are safety issues that the manufacturer has identified and agreed to fix for free. The report shows which recalls have been issued but does not always show whether the owner actually had the recall work done. You can check whether recalls have been completed by contacting the dealership with the VIN, or by visiting the National Highway Traffic Safety Administration (NHTSA) website and entering the VIN.
Some reports also include technical service bulletins (TSBs), which are notices from the manufacturer about known problems and how to fix them. A TSB doesn't mean the car is unsafe, but it signals that other owners have reported the same issue. If a car has multiple TSBs for the same system — say, three bulletins about transmission problems — that's worth investigating further.
How to order and read a vehicle history report
You can order a report from Carfax.com or AutoCheck.com by entering the VIN. Both charge a fee per report, though some dealerships provide free reports as part of their listing. You can also get a free report through some credit card companies or membership programs like AAA. The report is usually available within seconds.
When you read the report, look for the timeline at the top. It shows the sequence of events — when the car was registered, when accidents or service occurred, and when ownership changed. Below that, you'll see sections for title information, accident history, service records, and recalls. Red flags include title brands, multiple accidents, and open recalls that haven't been addressed.
If you're buying from a private seller, you can order the report yourself before you make an offer. If you're buying from a dealership, ask whether they've already run a report and can show it to you. Some dealerships include the report in the listing; others will provide it if you ask. Comparing a Carfax and AutoCheck report for the same car can give you a more complete picture, since the two services don't always have identical information.
What a history report doesn't tell you
A vehicle history report is one tool, not the whole picture. It doesn't include information about the car's mechanical condition, whether the engine runs smoothly, if the transmission shifts properly, or whether the interior is in good shape. It doesn't show unreported accidents or damage that was paid for out of pocket. It doesn't tell you about maintenance that happened at independent shops or dealerships that don't report to Carfax or AutoCheck.
A clean history report combined with a pre-purchase inspection by a trusted mechanic gives you much more confidence than either one alone. The mechanic can identify problems that don't show up in records — worn brakes, engine issues, rust, or signs of past damage that was never reported. If you're buying a used car, budget for a pre-purchase inspection regardless of what the history report says.
When to be cautious about a history report
Be cautious if the report shows a gap in the timeline — long periods where the car wasn't registered or serviced anywhere. This can happen if the car was stored, but it can also mean records are missing. If the mileage on the report jumps backward (the car shows 80,000 miles one year and 60,000 miles the next), that's a sign of odometer fraud, though this is rare in modern reports because the data comes from official sources.
If the report shows the car was registered in multiple states in a short time, or if it was registered in a state known for loose title laws and then quickly moved to your state, that can be a warning sign. Some people move cars between states to avoid title brands or to hide accident history. This isn't always a problem, but it's worth asking the seller why the car moved around.
If you see a salvage or flood title, or if the report shows the car was declared a total loss, think carefully before buying. These cars can be repaired and run fine, but they carry more risk. Have a mechanic inspect the car thoroughly, and be prepared for the car to be harder to insure and to lose value faster than a car with a clean title.
Frequently Asked Questions
Can I get a free vehicle history report?
Some dealerships provide free reports with their listings. You can also get a free report through certain credit card companies, AAA membership, or insurance companies. Otherwise, Carfax and AutoCheck charge a fee per report, usually between $20 and $40 for a single report. Buying a multi-report package is cheaper per report if you're shopping for multiple cars.
What if the history report shows an accident but the seller says it never happened?
The report is based on official records — insurance claims, police reports, and repair shop data. If an accident is on the report, it was officially recorded somewhere. The seller may not have been aware of it, or may be mistaken about the details. Ask the seller for their insurance records or contact information for the repair shop listed on the report to get more details about what happened.
Does a clean history report mean the car is safe to buy?
A clean report means no major accidents, title problems, or recalls were officially recorded. It doesn't tell you about the car's mechanical condition, unreported damage, or maintenance done at shops that don't report to Carfax or AutoCheck. Have a mechanic inspect the car before you buy, regardless of what the history report says.
Why do Carfax and AutoCheck show different information for the same car?
The two companies buy data from different sources and don't have access to the same records. One might have a repair record that the other doesn't, or one might have an insurance claim that the other missed. Checking both reports gives you a more complete picture than relying on just one.
What should I do if the car has a salvage title?
A salvage title means the car was declared a total loss by an insurance company and then repaired. The car may run fine, but it carries more risk and will be harder to insure and sell later. Have a trusted mechanic inspect it thoroughly, get a detailed estimate of any remaining repairs, and be prepared to pay less than you would for a car with a clean title.
