GMC SIERRA 2500 HD

The GMCSIERRA 2500 HD appears in NHTSA's Office of Defects Investigation database with 1 consumer safety complaints and 0 safety recalls across 1 model year (2024–2024). That averages roughly 1 complaint per model year, but the distribution is almost never even — most nameplates concentrate their defect reports in a handful of cohort years tied to specific platform refreshes, supplier changes, or component redesigns.

Complaint volume on a nameplate alone is not a reliability verdict: a long-running bestseller will accumulate more filings than a low-volume niche model simply because more of them are on the road. What matters is the year-over-year shape and the component concentration — which the table below isolates for the SIERRA 2500 HD by showing complaint count, crash count, fire count, and NHTSA safety rating side by side for each model year.

NHTSA has 2 investigation files tied to this model. Investigations precede recalls and signal that the Office of Defects Investigation is actively testing a theory about a specific component cluster. Together with the complaint-by-year breakdown and recall remedy status, they are the primary signals used by insurance actuaries, fleet managers, and used-vehicle appraisers when pricing GMCSIERRA 2500 HD risk.
