Mack recalls 2022-2024 Granite trucks with air brakes that may not have enough air volume, risking reduced braking performance and crashes. Owners receive free air tank upgrades.
Insufficient air volume can reduce braking performance and increase the risk of a crash.
Mack is recalling certain 2022-2024 Granite trucks because their air brakes have insufficient air volume, which can reduce braking performance and increase crash risk. This affects trucks that fail to meet federal air brake safety standards.
The air tanks in these trucks have less air volume than required for safe braking. This can cause reduced braking performance, making it harder to stop the vehicle, especially in emergency situations.
Owners of 2022-2024 Mack Granite trucks are affected. Truck drivers and fleet operators using these vehicles are most at risk due to potential braking issues.
Check if your truck was manufactured between 2022 and 2024 and has the model name 'Granite'. The recall was announced in March 2024, and owner notification letters were mailed to affected owners.
