Mack Trucks, Inc. (Mack) is recalling certain model year 2016-2017 Titan vehicles manufactured from February 25, 2015, through February 12, 2016. The bolt connecting the upper steering shaft to the lower steering shaft may not properly secure the upper steering shaft, which can lead to separation of the steering shaft.
Consequence

An interim notice was sent to Mack owners on March 21, 2016, and an interim repair is available now. A second notice was mailed on May 12, 2016. The final remedy is now available. Both remedies will be free of charge. Owners may contact Mack customer service at 1-877-800-4945 opt #1. Mack's number for this recall is SC0401.
