What's wrong?
The LED headlight on 2024-2025 Mack Granite (Gr) trucks is the front lamp assembly that lights the road and helps other drivers see the truck. It uses LED units and a mounted housing, with wiring harnesses that carry power to the lamp. The headlight has to stay aimed, powered, and protected while the truck moves over rough roads.
On affected trucks, the ball basket mount design does not give the headlight enough support. The harness routing and clipping points also do not protect the wiring as intended. Normal vibration and movement can stress the wiring and headlamp mount, which can lead the LED headlight to stop working.
There is no warning sign before failure. An owner will notice the problem only when a headlight is out, the road is not lit as expected, or another driver or inspector points out the failed lamp.
Who's affected?
Both model years identify the same left LED headlight component.

What's the safety risk?
Loss of headlight illumination reduces visibility and increases the risk of a crash. Because this recall involves lighting, avoid night driving if the headlights are not working, and contact a Mack dealer for next steps. Repair will be free at any franchised Mack dealer once Mack opens it.
What should I do?
- Check your VIN to confirm your 2024-2025 Mack Granite (Gr) is included in this recall.
- Wait for Mack's final-repair notice before scheduling the free LED-headlight replacement that fixes the headlight-failure risk.
- Call Mack customer service at 1-800-866-1177 with questions and reference recall number 25V756.
- Use extra care after dark until the repair is complete; loss of headlight illumination reduces visibility.
What happens at the repair
Mack has sent interim letters about the LED headlight safety risk. The final dealer repair is not open yet. Once available, a Mack technician will replace the LED headlights, and parts and labor will be free under the recall. Mack uses its standard reimbursement plan for documented out-of-pocket LED headlight repairs paid before the recall notice. Keep prior repair paperwork and contact Mack customer service to ask how to submit it.
