MACK

MACK is registered with NHTSA as a vehicle manufacturer and carries 155 consumer safety complaints across 30 nameplates in the Office of Defects Investigation public database. The brand has been the subject of 91 safety recalls and is currently tied to 5 active or historical federal investigations. Every one of those figures is pulled directly from NHTSA's published datasets, not from owner forums, manufacturer marketing, or third-party reliability surveys, so the numbers you see reflect the same data federal regulators use when they decide whether to escalate a preliminary evaluation into an engineering analysis or a formal defect order.

Model-level volume varies widely inside any automaker's portfolio: best-sellers accumulate complaints simply because more vehicles are on the road, while limited-run trims and discontinued nameplates often carry disproportionately high complaint rates per unit sold. Inside MACK's lineup, the single highest complaint count sits with the MACK (35 filings, model years 1975–1999), followed by CXU612 and ANTHEM (AN). Use the table below to compare nameplate-by-nameplate counts, then drill into a specific model to see which components dominate and which model years concentrate the crash, fire, and fatality reports.

No open NHTSA investigations are currently tracked against MACK in this dataset, meaning the Office of Defects Investigation is not, at this moment, reviewing a specific defect allegation for the brand. Recall status, by contrast, is backward-looking: it tells you what the manufacturer has already been compelled to remedy, not what they are being asked to remedy next. Together, complaints, investigations, and recalls form the three-layer early-warning system federal safety regulators have relied on since the National Traffic and Motor Vehicle Safety Act of 1966.
