2024 Mack Pinnacle (pi/pn) & 2025 Mack Pioneer PR (4) recall: brakes
⚠️ What's wrong
Mack Trucks, Inc. (Mack) is recalling certain 2024-2025 Pinnacle (PI/PN) trucks. The air tanks have an insufficient volume of air for the brake system. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
💥 The risk
Insufficient air volume can reduce braking performance and increase the risk of a crash.
🔧 The fix
Dealers will install the correct volume air tanks, free of charge. Owner notification letters were mailed February 10, 2025. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0473.
Is the fix free? Yes. Safety recall repairs are free at any authorized dealer under federal law, including parts and labor. (Vehicles more than 15 years old when the recall was announced can be excluded, but most manufacturers still fix them.)
