Carfax reports use standardized severity terms — minor, moderate, functional, and structural — to describe reported damage without disclosing every mechanical detail, and each term corresponds to a different level of impact on the car's safety, drivability, and resale value. Understanding these terms helps you interpret a report accurately instead of guessing at what a label actually means.
Damage Severity Terms
Minor Damage Cosmetic-level damage — think small dents, scuffed bumpers, or minor scratches — that doesn't affect the car's structural integrity or safety systems. Generally has minimal impact on resale value.
Moderate Damage Damage requiring more significant bodywork or component replacement (a damaged fender, cracked bumper cover, or non-structural panel damage), but still not affecting the frame or safety systems. Buyers should expect a modest value reduction and should confirm the repair was done properly.
Functional Damage Damage that affected the vehicle's ability to operate normally at the time — such as damage to the engine, transmission, or suspension — even if it has since been repaired. This is a meaningfully bigger flag than cosmetic damage and warrants a mechanic's inspection before purchase.
Structural Damage The most severe classification — damage affecting the vehicle's frame, unibody, or core structural components. This can affect crash safety even after repair and typically has the largest impact on resale value. A pre-purchase inspection is strongly recommended for any vehicle with structural damage history.
Title Brand Terms
Branded Title A designation applied by a state DMV when a vehicle has experienced a significant event — such as being declared a total loss, salvaged, or rebuilt — permanently attached to the vehicle's title record.
Salvage Title Issued when an insurer declares a vehicle a total loss, usually because repair costs exceeded a set percentage of its value. A salvage-titled car generally cannot be legally driven until it's repaired and re-inspected.
Rebuilt Title Applied after a salvage-titled vehicle has been repaired and passed a state inspection, allowing it to be legally registered and driven again. Rebuilt-title vehicles typically sell for meaningfully less than clean-title equivalents.
Flood Damage Indicates the vehicle was submerged in water significant enough to be reported to an insurer or DMV, which can cause long-term electrical and corrosion issues even after cosmetic repairs.
Lemon/Manufacturer Buyback Applied when a manufacturer repurchases a vehicle due to unresolved defects under lemon law provisions — the vehicle may have been resold afterward but retains this history permanently.
Vehicle Type & Usage Terms
Commercial Vehicle Indicates the vehicle was registered or used for business/commercial purposes rather than personal use, which can imply higher mileage accumulation or more demanding use patterns.
Vehicle Reconditioned Indicates cosmetic or mechanical reconditioning was performed, often at a dealership, before resale — generally a routine and neutral entry rather than a red flag.
Severity Ranking at a Glance
| Term | Severity | Typical Resale Impact |
| Minor Damage | Low | Minimal |
| Moderate Damage | Medium | Modest reduction |
| Functional Damage | High | Noticeable reduction |
| Structural Damage | Highest | Significant reduction |
The Bottom Line
These terms exist to standardize how damage is reported across thousands of data sources, but they're intentionally general. Any damage entry beyond "minor" is worth following up on with a pre-purchase inspection, since the label alone won't tell you exactly what was repaired or how well.
FAQs
What does "functional damage" mean on Carfax?
It means damage affected the vehicle's operational systems — engine, transmission, or suspension — at the time it occurred, even if since repaired.
What is a branded title?
A permanent DMV designation applied after a significant event like a total loss, salvage, or flood damage, which stays with the vehicle's title history.
Is moderate damage a serious red flag?
Not necessarily — it typically means non-structural bodywork was needed, but it's still worth confirming the repair quality before buying.
What does "vehicle reconditioned" mean?
It usually indicates routine cosmetic or mechanical prep work done before resale, and is generally not a warning sign on its own.
