What's wrong?
The high-voltage traction battery on 2022-2023 Mack Lrbe (Electric) trucks stores the electrical energy that drives the propulsion system. Inside the battery pack, bus bars connect battery cells so power can move through the pack in a controlled path. Threaded inserts, called rivnuts, help hold those internal connections in place.
On affected trucks, rivnut threaded inserts inside the battery were over-tightened during assembly or rework. That extra torque can break the insert or disturb the bus bar connection between cells. A damaged connection inside the battery can create arcing, and that arcing can lead to a short circuit inside the high-voltage pack.
The warning sign is a battery overheating alert from the vehicle battery thermal management system. The driver can see that warning on the instrument cluster or driver information display.
