The short answer
NHTSA received Terex South Dakota, Inc.’s report on May 15, 2017. Copied from NHTSA on Oct 21, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
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.
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.
