What the authority reported

Issue: On certain trucks, the connector(s) for the rear brake modulator(s) may not have proper wiring protection. As a result, the rear brake modulator(s) could short circuit and cause a loss of antilock braking system (ABS) and electronic stability control (ESC). Safety Risk: A loss of ABS and ESC could increase the risk of a crash. Corrective Actions: Mack will notify owners by mail and advise you to take your truck to a dealership to inspect and, if necessary, replace the rear brake modulator(s). The dealer will also install a cover on the connector(s).

What to do

Follow the instructions in the official notice — recall remedies (refund, repair, replacement, or disposal) are defined by the issuing authority and the responsible business, and they differ per recall. Do not rely on summaries, including this one.
