What's wrong?
The certification label on the 2021 Thomas Built Buses Saf-T-Liner Hdx is supposed to tell operators and service staff the bus's gross axle weight rating, or GAWR. GAWR is the maximum weight each axle is rated to carry. That label also supports compliance with the electronic stability control requirements for heavy vehicles.
On the affected bus, the GAWR on the label is improperly stated. The issue is not a broken mechanical part. It is incorrect safety and compliance information on the vehicle label, which means the bus does not fully comply with the electronic stability control standard tied to heavy vehicles.
There is no warning sign before failure. An owner or operator will not feel, hear, or see a driving symptom from the label itself because the defect is printed information, not a worn component.
