## NHTSA's summary

Certain MACK CHU, CXU, and GU trucks built between 11/11/2013 and 01/14/2015, equipped with front radar may experience loss of front object detection or erratic operation of cruise control functions. The terminal seals of the harness is allowing moisture and corrosion to build up in the front radar harness. To ensure proper operation of the front radar, the harness is inspected for the proper seal and/or corrosion. If the harness or seal fail inspection, replacement of the harness is required. Follow the inspection and repair procedures outlined in this document.
