FREIGHTLINER M2
PowerObserved 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 Nov 6, 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 – Nov 3, 2026.
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.

Established platform and cab splits
Only externally sourced labels are listed; the model rollup above still includes VINs whose labels are not established.
