What the authority reported

Issue: On certain trucks, a software problem could cause reduced trailer braking when towing a tanker trailer without internal baffles.

Safety Risk: Reduced braking can cause extended stopping distances and 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 update the vehicle software.

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.
