Service bulletin GCUS-9-222
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
14329B - Special Coverage (revised to update the Part Information and torque specs within the Service Procedure). Some 2008-2011 model year (MY) Buick Enclave, 2009-2011 MY Chevrolet Traverse, 2007-2011 MY GMC Acadia, and 2007-2010 MY Saturn OUTLOOK vehicles may develop a power steering pump wear condition that can cause an intermittent drop of power steering hydraulic pressure that will cause reduced or loss of steering assist. The vehicle may revert to manual steering which requires greater driver effort, particularly at low vehicle speeds. Dealers are to flush the power steering system, replace the power steering pump, and if it hasn't already been replaced, install a new steering gear valve housing.
