What's wrong?
The light control module on these 2018 Mack Anthem (An), Granite (Gu), Pinnacle (Cxu), and Pinnacle (Pi/Pn) trucks is the electronic controller for key visibility systems. It manages exterior lights, interior dashboard lighting, and windshield wiper operation, so the driver can see the road, be seen by other traffic, and keep the windshield clear.
On affected trucks, an electrical overload can damage the light control module. The recalled module, part number 23078913, included a MOSFET, an electronic switching part, that was removed in the revised design. That change prevents overload damage that can shut down the module.
If the module fails, the truck can lose exterior lighting, dashboard lighting, and windshield wipers. Owners can notice fault codes or lights flickering before the lights go out. Those warnings mean the control module needs dealer attention.

What's the safety risk?
Loss of exterior lighting or windshield wiper function reduces visibility and can increase the risk of a crash. Fault codes or flickering lights are warning signs before the lights go out. If those appear, avoid poor weather or low light and schedule service promptly. Repair is free at any franchised Mack dealer.
What should I do?
- Check your VIN to confirm your 2018 Mack Granite (Gu), Pinnacle (Cxu), Pinnacle (Pi/Pn), or Anthem (An) is included in this recall.
- Contact a franchised Mack dealer to schedule the free LCM replacement and reprogramming that fixes the lighting and windshield-wiper failure.
- Bring the recall notice if Mack mailed one, or reference recall number 18V152 when you call.
- Call Mack customer service at 1-800-866-1177 with questions about recall number 18V152.

What happens at the repair
At the dealer, a Mack technician replaces and reprograms the light control module, the LCM, so the exterior lights, dashboard lighting, and windshield wipers are controlled by a corrected module. The dealer repair is available now, and parts and labor are covered under the recall. If you've already paid for a related LCM repair before the recall notice, Mack's general reimbursement plan covers eligible expenses. Bring repair paperwork to the service desk.
