Mack Trucks, Inc. reported this defect to federal regulators on Feb 19, 2016 and put the number of vehicles at risk at 33,981. The repair is free for as long as the recall stands.
The defect
Mack Trucks, Inc. (Mack) is recalling certain model year 2012-2016 Granite (GU), Pinnacle (CHU, CXU), TerraPro (LEU, MRU), Titan (TD), and LR trucks manufactured from September 1, 2011, through September 8, 2015. The cap nut that retains the interaxle driveshaft yoke to the rear axle input shaft may loosen.
The risk
If he cap nut loosens and falls off, the yoke can separate from the axle input shaft and allow the drive shaft to disconnect, increasing the risk of a crash.
The remedy
Mack will notify owners, and dealers will replace the cap nut. The input shaft threads will be inspected for damage. Any damaged input shaft will be replaced. These repairs will be performed free of charge. An interim notice was sent to owners on April 25, 2016. The recall began on June 7, 2016. Owners may contact Mack customer service at 1-610-709-2131. Mack's recall campaign number for this recall is SC0399.

A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 16V099000.
