Recall 14V545 affects 538 2013-2015 Mack Pinnacle (Cxu) and Chu trucks for missing obstruction alerts. Repair is free at any franchised Mack dealer.
Mack is recalling 538 2013-2015 Pinnacle (Cxu) and Chu trucks equipped with adaptive cruise control because a software error can prevent visual or audible obstruction alerts from reaching the driver. Without that warning, the driver has less time to react to something in the truck's path, and Mack dealers will complete the repair free of charge.

What's wrong?
The adaptive cruise control system on 2013-2015 Mack Pinnacle (Cxu) and Chu trucks helps manage following distance when the system is active. It uses forward-looking detection to identify an obstruction ahead, then it is supposed to warn the driver with visual and audible alerts. Those alerts matter because the driver still has to steer and brake the truck.
On affected trucks, a software error in the adaptive cruise control system interferes with that warning function. The system detects an obstruction in the road, but the truck fails to provide the expected visual or audible alert to the driver. That leaves the driver with less notice from the driver-assistance system.
There is no warning sign before failure. The issue is in the warning software, so the driver is not given a clear symptom before the alert fails to appear.
