What is a Carchieve vehicle history report?

A Carchieve report is a complete safety and records check on any U.S. vehicle. Enter the 17-character VIN and you get the decoded vehicle identity and full specifications, every open safety recall, owner-reported complaints by system, official NHTSA crash-test ratings, and a buyer action plan, in one clean report and a downloadable PDF.

How is Carchieve different from a typical VIN lookup?

Carchieve doesn't just dump raw data. It authenticates the VIN, organizes every federal safety record into a buyer-ready dossier, scores the vehicle, and tells you exactly what to inspect, ask and verify before you pay, the way a careful mechanic would read the car.

How fast will I get my report?

Reports are generated in under a minute. As soon as your VIN is checked against the recall, complaint, ratings and identity databases, your report and PDF are ready to view and download.

Can I buy more than one report?

Yes. A single report is $24.99. If you're comparing several cars, the 3- and 5-report bundles save you money per report and the extra credits stay in your account until you use them.

What information do I need to run a report?

Only the 17-character Vehicle Identification Number (VIN). The VIN is on the lower-left corner of the windshield, the driver-side door jamb, and the vehicle title or registration.

Where does the data come from?

Every report is built from authoritative U.S. vehicle databases, including the National Highway Traffic Safety Administration (NHTSA) recall, complaint and 5-Star safety-rating programs and the federal VIN product information catalog. Carchieve authenticates the VIN check digit so you know the identity is genuine.

Can I share the report with a seller or mechanic?

Yes. Every report includes a professionally formatted PDF you can download, print, or forward to a private seller, dealer, or mechanic to support your buying decision.

Quick answer

TSB: During the manufacturing process, tires are mounted on the vehicle as matched sets to help reduce conditions such as pulling or drifting. If the wheels are replaced or refinished before vehicle delivery, it is important that the tires remain on the vehicle in the same location and in the same direction of rotation. Refer to the Tire Positioning Procedure in this bulletin to ensure that the original tires stay in the same location on the vehicle.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.

Frequently asked questions

What is NHTSA service bulletin 10178527?

Is a service bulletin the same as a recall?

No. A recall is a safety campaign with a required remedy for affected VINs. A service bulletin or manufacturer communication usually describes diagnostic, repair, software, warranty or service information.

How should a used-car buyer use this bulletin?

Use it as a research signal. Compare it with recalls, owner complaints, service records, a VIN report and an independent inspection before buying.

Check the exact VIN before you buy

Model-level pages show public safety patterns. A full VIN report helps confirm the exact vehicle, decoded specs, recall applicability and buyer checks.
