GM has issued a Service Bulletin #09207A as of September 2009
This bulletin covers three items;
HVAC Reprogram: This will help prevent the evaporator from freezing up after extended highway drives
Engine Harness Position Inspection: This impacts LS3 SS models and will verify the harness bracket does not make contact with the heater hose clamps
Rear Spoiler Fasteners: Impacting only vehicles with a VIN lower than A9126194 and equipped with a rear deck spoiler, this will replace all six fasteners and use Loctite 242 Threadlocker to ensure a secure installation
