What's wrong?
The high voltage battery pack in the 2022-2023 Mack Lrbe (Electric) truck stores the energy that drives the electric propulsion system. Coolant lines inside the pack move heat away from the battery cells so the pack stays within its designed temperature range during charging and operation.
On affected trucks, a coolant line in the battery pack was not fully seated and locked during assembly. The issue traces to inadequate process controls during Akasol Gen 3 battery pack assembly. If the line moves out of position, coolant can leak from the pack. Loss of coolant can lead to an electrical short circuit inside the high voltage battery system.
There is no warning sign before failure. The owner is not expected to see a dashboard message, sound, smell, or driving symptom tied to this coolant-line seating problem before the fault occurs.
Who's affected?
Both listed model years use the same high-voltage traction battery component for this recall.

What's the safety risk?
A battery short circuit increases the risk of a fire. There is no warning sign tied to this battery issue, so do not rely on a symptom to tell you the truck is affected. Confirm the VIN and follow Mack's recall instructions. Repair will be free at any franchised Mack dealer once available.
What should I do?
- Check your VIN to confirm your 2022-2023 Mack Lrbe (Electric) is included in this recall.
- Wait for Mack's repair instructions before scheduling the free high-voltage battery inspection and replacement.
- Contact a franchised Mack dealer after Mack opens the repair, and explain that the coolant line in the battery pack needs inspection for a seating and locking defect that can lead to coolant loss and a battery short circuit.
- Bring the recall notice if Mack mailed one. If not, reference recall number 23V281 and Mack recall SC0442 when you call.
- Call Mack customer service at 1-800-866-1177 with questions about timing, inspection, or the free battery replacement path.
What happens at the repair
The final dealer repair is still under development. Once it opens, a Mack technician will work with Akasol, the battery manufacturer, to inspect the high voltage battery pack and replace affected batteries as needed. The recall repair will be free once available, with parts and labor covered. The repair path is focused on the battery pack coolant line issue, because an unseated coolant line can allow coolant loss and an electrical short circuit.
