How to dispute or correct a Carfax or AutoCheck record

This guide is about getting a wrong entry fixed. What the labels mean and where the records come from is covered in how accidents show up on Carfax and AutoCheck. The steps below are what each company’s own pages said when we checked them in November 2026. Check the pages again before you submit, because processes change.

Is it an error?

A severity label that feels harsh is not always wrong. Carfax’s glossary says structural damage can occur in accidents at every level, so a structural entry on a low-speed accident can be accurate. Compare the entry with the invoice line by line before you dispute it.

Carfax: the Data Research Request form

Carfax’s support page says vehicle owners who think there is an error on a report can tell it by filling out the online Data Research Request form. Its main points, as published:

• Owners submit. If you do not own the vehicle, Carfax asks you to have the owner contact it. Businesses that do not subscribe are pointed to Carfax’s business channels.
• No phone requests. Carfax says it does not offer phone support, because its online channels let it receive links and supporting documents.
• A case number. Once a request is submitted, Carfax says a Resolution Manager is assigned and you receive an email with a case number. The manager researches the request and replies by email.
• Adding missing records. Carfax also uses the same form for owners who want to add a police report or repair order to the report.

AutoCheck: the dispute form

AutoCheck’s Dispute page is a contact form. You choose “Vehicle history report record dispute” as the reason, and the form asks you to “paste the section in question” into the description, with your name and email address. The VIN field is marked optional, but include it. The page also says live chat is open Monday through Friday.

Fix it at the source too

A report repeats what its sources sent, so a correction at the source helps keep the error from coming back.

• Title brands such as salvage or flood are labels states assign, as the NMVTIS consumer page explains. A wrong brand is a matter for the state titling agency that applied it.
• Police report errors, such as the wrong VIN or plate, go to the agency that wrote the report.
• Dealer, auction or shop entries can be raised with the business that reported them.

What to send

• The report page, or the section of it, showing the entry you dispute
• The VIN and your title or registration showing ownership
• The police report, or a letter from the agency, for date, location or VIN errors
• The final repair invoice and supplements for severity or description errors
• The insurer’s claim letter or estimate showing the claim number and date of loss
• A short explanation: what the entry says, what is wrong, and what the documents show

Keep copies of everything and the case number or confirmation email. If you have a diminished value claim open, keep your appraiser informed of the result.

What cannot be removed

Both published processes are built around errors. Neither company’s page offers to remove an accurate accident record because it lowers the car’s value. If the accident happened and is described correctly, expect it to stay.

That is also why removal would not erase a loss in value even if it happened. Diminished value is measured from the market value of the car once repaired, and buyers learn about repairs in other ways: inspections, paint readings, the seller’s own answers and, in some states, damage disclosure rules. North Dakota’s vehicle damage disclosure statute, for example, came up in Sullivan v. Pulkrabek (N.D. 2000), where the owner said it lowered his trade-in value. An appraisal that assumed a clean history could be discredited the moment an adjuster or buyer found the repair.

When a correction matters for a claim

• A wrong record from someone else’s accident can lower your car’s value for reasons the at-fault driver did not cause. Fix it before an appraisal, so the appraisal measures only the loss from your accident.
• An overstated description of your accident does not change what the invoice shows. The appraisal works from the invoice, and the correction protects your price when you sell.
• A missing record is not a reason to skip a claim. See why accidents can appear months later.

A diminished value appraisal is based on the repair records and the market, and it states the history it assumed. Send the invoice and the report you are disputing for a free claim review. If you order, a typical appraisal is $250–$350.
