NHTSA defect investigations

NHTSA's investigations file lists the 2006 Western Star 4900 in 2 investigations. Audit Queries and Equipment Queries are administrative investigations: they look at whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules, not at a possible vehicle defect. A listed model year means only that an investigation names it; it says nothing about any particular vehicle. An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
