What's wrong?
The traction battery pack on 2022-2025 Mack Lrbe (Electric) trucks stores the high-voltage power used by the electric propulsion system. The BorgWarner GEN 3 pack feeds power to the drive system and is managed by battery controls that watch temperature and operating condition. It is built so internal hardware stays secured inside the pack while the truck operates.
On affected trucks, inadequate manufacturing process controls at BorgWarner Akasol left suspect battery packs with loose hardware. That hardware can fall inside the battery pack. If it contacts the wrong internal points, it can create a short circuit inside the high-voltage battery. Mack's remedy is to replace the affected batteries with packs produced without this manufacturing issue.
The warning sign is a battery overheating alert from the vehicle battery thermal management system. The alert appears through the instrument cluster and driver information display, so treat that warning as a battery-system problem that needs dealer attention.
Who's affected?
Each listed year uses the same BorgWarner GEN 3 high-voltage traction battery.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
A short circuit increases the risk of fire. The battery thermal management system warns the driver through the instrument cluster and driver information display when the battery overheats. If that warning appears, pull over safely, turn the vehicle off, and contact a Mack dealer before continuing. Repair is free at any franchised Mack dealer.
