Certain Mack Trucks Found Noncompliant
Mack Trucks says some model year 2017–2026 Pinnacle (PI/PN) and model year 2017–2019 CHU trucks do not fully meet Federal Motor Vehicle Safety Standard No. 121 (Air Brake Systems). Mack filed noncompliance reports on December 20, 2024 (amended January 15, 2025) and petitioned NHTSA on January 15, 2025, asking that the noncompliance be judged inconsequential for motor vehicle safety. While NHTSA considers the petition, the company has asked for a decision that may mean no immediate changes or costs for owners and drivers of those trucks.
