2017 Terex Digger Derrick Problems, Complaints & Recalls

Problem: Terex South Dakota, Inc. (Terex) is recalling certain 2017-2018 Terex Digger Derrick vehicles. The guide bar that attaches the pole guide arms to the pole guide tilt bracket may have insufficient welds, possibly resulting in the guide arm falling while in use.

Risk: If the pole guide arm falls, it may strike any nearby personnel, increasing the risk of injury.

Fix: Terex will notify owners, and dealers will replace the affected guide bars, free of charge. The recall is expected to begin December 14, 2018. Owners may contact Terex at 1-605-882-4000. Terex's recall number for this recall is SN669.

Problem: Terex South Dakota (TSD) is recalling certain 2012-2017 Digger Derricks and Aerial Devices, models C4000, C5000, C6000, C7000, General, HR, OM, RM,RMX, SC, SCM, TC, TCX, TL, TM, and XT, built on Freightliner chassis with SmartPlex engine controls. The vehicles have a switch to monitor whether the hood is open or not. If the switch thinks that the hood is open, the vehicle software may disable the Aerial or Digger Derrick remote engine control functions.

Risk: If the hood switch prevents the remote engine controls from shutting the vehicle engine down in the event of a hydraulic issue on the Aerial or Digger Derrick, it may increase the risk of an injury.

Fix: TSD will notify owners, and dealers will reprogram the vehicles to only disable the engine start function if the switch indicates that the hood is open, free of charge. The recall began on June 28, 2017. Owners may contact TSD Customer Service Department at 1-800-982-8975. TSD's number for this recall is SN659.
