What's wrong?
The chassis harness on these Mack Granite (Gu), Titan, and Pinnacle (Chu) trucks is the bundle of wiring that carries electrical power and signals along the frame. The air lines are pressurized hoses that feed the truck's air brake system. Clips on the crossmember hold both sets of lines in place and keep them away from the rotating driveline.
On affected 2009, 2010, 2012, 2013, 2014, 2015, 2016 trucks, the routing and clipping instructions did not clearly define how those lines had to be secured. When the harness and air lines are not clipped correctly, they can drop from the crossmember. Once loose, they can get twisted into the driveline, damaging chassis wires or air lines.
There is no warning sign before failure. A driver is not given a light, sound, or handling change that confirms the harness or air lines have come loose.

What's the safety risk?
NHTSA campaign 15V522 says loose electrical cables and air lines can fall into the driveline. If they tangle there, the electrical system and braking system can be affected, increasing crash risk. Drive with caution and schedule the inspection soon. Repair is free at any franchised Mack dealer.
What should I do?
- Check your VIN to confirm your 2009, 2010, 2012, 2013, 2014, 2015, or 2016 Mack Granite (Gu), Titan, or Pinnacle (Chu) is included in this recall.
- Contact a franchised Mack dealer to schedule the free inspection and clipping repair that keeps the chassis harness and air lines from dropping into the driveline.
- Bring the recall notice if Mack mailed one. If not, reference recall number 15V522 when you call.
- Call Mack customer service at 1-800-528-6586 with questions about scheduling or repair timing.
- Drive cautiously until the repair is complete, and leave extra following distance because the defect involves the electrical system and air-brake lines.
What happens at the repair
At the dealer, a Mack technician inspects the chassis harness and air lines where they route near the crossmember and driveline. The technician properly clips the harness and air lines to the crossmember so they cannot drop into the driveline. Parts and labor are free under the recall, and the repair is available through a Mack dealer. Mack has a general reimbursement plan on file for owners who already paid for this repair. Bring repair documentation and ask Mack customer service or the dealer service desk how to submit it under that plan.

Frequently asked questions
What is recall 15V522?

Is the recall repair free?
Yes. Federal recall law requires the manufacturer to perform the recall repair at no cost. Mack dealers will inspect the affected trucks and properly clip the chassis harness and air lines free of charge.
