Model platform statistics

CHEVROLET GMT-400

Power

Observed trucks and fleets, single-power-unit inspection outcomes, and failure groups grounded in the federal CFR section and BASIC reference.

Interpretation guardrail

These roadside results reflect operators' maintenance and duty cycle as much as the vehicle. They are not evidence of a manufacturer defect. OOS rates and failure frequencies are normalized per inspection, never presented as a raw count pretending to be a rate.

Violation detail is as of Jun 16, 2026; it is not current. Platform and cab labels appear only where external evidence established them. A missing label means “not established,” never “no.”

Observed model footprint

Attributed inspection span: Jun 13, 2023 – Jul 30, 2026.

Distinct attributed trucks358
Exactly one resolvable power unit
Attributed inspections538
541 resolved unit records
Observed fleets357
Distinct inspection USDOTs
Reported trucks2,509
339 fleets with established truck_units

Reported trucks sum FMCSA truck_units across distinct observed fleets after the existing plausibility clamp. It is operator context, not this model's production count, and never uses power_units or MCS-150 mileage.

Level-scoped OOS outcomes

Rates count OOS inspections only inside the same inspection-level population used by their denominator.

Vehicle OOS rate38.9%
vs 22.26% national · 169 of 434 level 1/2/5/6 inspections
Driver OOS rate14.8%
vs 6.67% national · 78 of 528 level 1/2/3/6 inspections

Established platform and cab splits

Only externally sourced labels are listed; the model rollup above still includes VINs whose labels are not established.

No platform or cab label is established for this model. That does not mean the model has no platform variants or cab configurations; it means this store has no sourced label to publish.
