Red Flags in a CARFAX Report That Could Save You Thousands

Not every Carfax report is accurate, which can be confusing for you. You must pay attention to these red flags in a Carfax report.

1.   Multiple Owners or Too many

This is one of the biggest red flags in a used car’s Carfax report. If multiple individuals own a vehicle, there may be something suspicious about it. Therefore, we recommend opting for cars that have had a limited number of owners.

2.   Accidental History

The minor accident history is excellent; however, if a car has undergone severe damage, it may not be a good option to buy. We do not recommend these vehicles due to their accident history, which includes structural damage, airbag deployment, and a rebuilt title. Not all repair shops are equal. Even if damage is listed as “repaired,” it’s smart to have your trusted mechanic inspect the vehicle for quality of repairs, paint inconsistencies, and alignment issues.

3.   Stolen or Snatched

If the used car’s Carfax report indicates any history of theft, even if it has been recovered, it’s still not the best option. The thieves might have stripped the vehicle of its valuable parts, rendering it unreliable and less durable in the long term. However, if you still opt for it, make sure to ask a trusted mechanic for an inspection.

4.   Too Much Travel History

Of course, every used car will have a travel history in its Carfax report. However, there are a few key points to note. If a vehicle has a healthy travel history, it may indicate that the seller has moved across state lines to conceal salvage titles. If you notice that a vehicle’s title history spans several states in a short time, that’s a red flag.

5.   Unsuccessful Emission Test

Emission tests are conducted on every vehicle, and it’s not a significant issue. It is generally used to measure and check the amount of pollution a car emits. If your Carfax report shows a positive emission test, there is nothing to worry about. Dealerships are required by law to sell cars with valid emissions records, but private sellers aren’t held to the same standard. Always check that the emissions status is up to date before making a purchase.

Conclusion

A Carfax report for used cars is highly recommended, as it contains information such as accident history, title, travel and ownership history, and various tests. We have outlined several key indicators and essential sections of a Carfax report, helping you secure a great deal on your next car.

FAQs

How do I know if the title is clean on the Carfax report?

Every Carfax report has a separate section for the Title history or Title check. The vehicle might have titles such as salvage, junk, odometer rollback, and flood. If none of these are listed and it says something like “Clean Title” or “No problems reported”, then you’re good, meaning it is a clean title.

Do dealerships lie on the Carfax report?

Dealerships can’t directly alter Carfax reports, as the data comes from third-party sources, such as DMVs, insurers, and service centers. However, some may misrepresent or downplay the report’s contents, such as accidents or title issues. Always verify the Carfax yourself, check for red flags (such as title changes or odometer inconsistencies), and obtain an independent inspection before making a purchase.
