Mack Granite trucks recalled for insufficient air brake tank volume

Mack is recalling 2022-2024 Granite vehicles because air tanks lack sufficient volume for proper brake system function. This can reduce braking performance and increase the risk of a crash.

What this means for you

Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Our severity reasoning: This recall involves a critical safety system (air brakes) with potential for significant harm (reduced braking performance, increased crash risk). However, the source text does not report any actual crashes, injuries, or fatalities, making the hazard theoretical rather than confirmed.

Plain-English summary

Mack Trucks, Inc. is recalling certain 2022-2024 Mack Granite (GR) vehicles. The air tanks in these vehicles have insufficient volume to provide adequate air for the brake system, causing them to fail to comply with Federal Motor Vehicle Safety Standard number 121 (Air Brake Systems).

Insufficient air volume can reduce braking performance and increase the risk of a crash. Affected owners were notified by letter starting March 14, 2024.

Mack dealers will add additional air tank volume to affected vehicles at no cost. Owners can contact Mack customer service at 1-800-866-1177 (recall number SC0458) or the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153) for more information.
