Recall 14V078 affects 70,208 2007-2015 Mack trucks for EPDM water contamination that can cause fire. Repair is free at any franchised Mack dealer.
Mack is recalling 70,208 2007-2015 Td and Granite (Gu) trucks because water leaks around the windshield can contaminate the Electronic Power Distribution Module with road salts. Those deposits can bridge circuits and create a high resistance short that raises the risk of a fire, and Mack dealers will complete the recall repair free of charge.

What's wrong?
On 2007-2015 Mack Td, Granite (Gu), Pinnacle (Cxu), Gu, Chu, Cxu, and Pinnacle (Chu) trucks, the Electronic Power Distribution Module, or EPDM, is the truck's electrical power distribution box. It routes battery power to key circuits and helps protect the electrical system from faults, much like a central junction point for heavy truck wiring.
On affected trucks, water can leak in and around the windshield and reach the EPDM. When that water carries road salt, salt deposits build up on the module. The contamination can cause localized heat damage in the electrical distribution area and keep current from staying on the intended paths. Mack's repair focus is better sealing at the windshield and bulkhead, plus a protective shroud over the EPDM.
There is no warning sign before failure. A driver should not wait for a light, smell, or visible electrical problem before treating the recall as active if the VIN is included.

A matching year and Mack model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Contaminant deposits can bridge circuits in the EPDM and create a high resistance short, increasing the risk of a fire. Schedule the inspection soon, and follow the dealer's guidance if contamination or a leak is found. Repair is free at any franchised Mack dealer.
What should I do?
- Check your VIN to confirm your 2007-2015 Mack Td, Granite (Gu), Pinnacle (Cxu), Gu, Chu, Cxu, or Pinnacle (Chu) is included in this recall.
- Contact a franchised Mack dealer to schedule the free EPDM inspection and leak repair that addresses water contamination in the electrical module.
- Bring the owner letter if you have it. Reference recall number 14V078 when you call.
- Ask the dealer what to do before the appointment if the truck has windshield leaks or signs of electrical overheating.
What happens at the repair
At the dealer, a Mack technician inspects the Electronic Power Distribution Module for contamination from windshield-area water leaks. If contamination is found, the technician replaces the EPDM and fixes the leak source covered by the recall. The inspection, replacement, and related leak repair are free under the recall. Mack used its general reimbursement plan on file, so if you already paid for this EPDM-related repair, ask Mack Trucks or the service desk how to submit repair documentation for review.

Recall 14V078 covers 70,208 2007-2015 Mack Td, Granite (Gu), Pinnacle (Cxu), Gu, Chu, Cxu, and Pinnacle (Chu) vehicles with possible water contamination in the Electronic Power Distribution Module. Contaminants can bridge circuits, create a high-resistance short, and increase fire risk.
What should I do if my 2007-2015 Mack Td, Granite (Gu), Pinnacle (Cxu), Gu, Chu, Cxu, or Pinnacle (Chu) is on this recall?
Check your VIN to confirm your specific Mack vehicle is included in recall 14V078. If it is, contact a franchised Mack dealer and reference recall number 14V078 or Mack recall SC0375. The dealer will inspect the Electronic Power Distribution Module and repair the issue for free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. Mack dealers will inspect the Electronic Power Distribution Module, replace it if contamination occurred, and address the water leak free of charge.
What is the safety risk?
The safety risk is fire. Water leaks around the windshield can let road-salt contamination reach the Electronic Power Distribution Module. Those deposits can bridge circuits and create a high-resistance short, increasing the risk of a fire.
What if I bought my Mack vehicle used?
The free recall repair still applies. Recall coverage follows the VIN, not the first owner. Check your VIN to confirm whether your Mack vehicle is included, then call a franchised Mack dealer with recall number 14V078 or Mack recall SC0375.
