Model platform statistics

INTERNATIONAL LA677

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 12, 2023 – Aug 19, 2026.

Reported trucks18,646

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 rate35.6%
vs 22.26% national · 109 of 306 level 1/2/5/6 inspections
Driver OOS rate5.1%
vs 6.67% national · 19 of 369 level 1/2/3/6 inspections
