Frequently asked

What does a CurbSpec report show for a Chevrolet Silverado / GMC Sierra 1500 Duramax?
A reviewed maintenance calendar for this family, due/overdue spend at your stated mileage, NHTSA campaigns filtered to this vehicle's engine and fuel, and any known issues found for your specific VIN or listing — including live research when the library doesn't have an entry yet.
What years does the Chevrolet Silverado / GMC Sierra 1500 Duramax calendar cover?
2020–2026 today. A vehicle outside that range still gets a compiled report — the maintenance outlook is researched live instead of pulled from the reviewed calendar, and it's labeled as researched, not reviewed.
Does this cover every Chevrolet Silverado / GMC Sierra 1500 Duramax engine or trim?
3.0 I6 Duramax on 1500. The 6.6 HD CP4 pump is a different family. A vehicle outside this specific calendar's scope still gets a report from CurbSpec — it's just researched live for that exact VIN or listing instead of pulled from this reviewed calendar.
Is this a Carfax or vehicle history report?
No. CurbSpec is not a title, accident, or ownership history report. It answers what a vehicle is about to cost to keep — due and upcoming maintenance spend, known issues, and safety campaigns — not what happened to it in the past.
How much does a CurbSpec report cost?
$12.99, one time, per vehicle. No subscription, no account required, and no ads — the preview is free; paying unlocks the line items, cost bands, and known-issue writeups at the same URL.
