Frequently asked

What are the known issues with a Chevrolet Silverado / GMC Sierra HD Duramax?
The reviewed library for this family currently lists: High-pressure fuel pump (Bosch CP4) metal contamination (LML/LGH Duramax, 2011–2016). Onset mileage, cost ranges, and full writeups are on the compiled sheet for your specific VIN or listing — these titles are shown here without cost bands or line items so you can see what's tracked before you paste anything.
What years does the Chevrolet Silverado / GMC Sierra HD Duramax calendar cover?
2011–2026 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 HD Duramax engine or trim?
6.6 Duramax 2500/3500. Not the 3.0 1500 Duramax. 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.
