Service bulletin GCUS-3-553
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
15801 - Customer Satisfaction Program. (2012 model year repair suspended) Vehicles equipped with Duramax Diesel Engine (RPO LGH or LML) and Ambulance Upfitter or Fire Truck Upfitter (RPO YF2 or ANM), may have a condition in which the emission control system as designed will limit speed under certain conditions. The EPA has approved General Motor?s request to remove the emission control system speed limitations on these emergency vehicles where applicable. Dealers are to reprogram the Engine Control Module (ECM) with new calibration for emergency vehicles, which will remove the emission control system speed limitations, and also provide an earlier warning for Diesel Particulate Filter (DPF) regeneration.
