Condition
On certain 2008 model year Chevrolet Colorado and TrailBlazer; and GMC Canyon and Envoy vehicles equipped with an AM/FM Stereo with CD/MP3 Player (RPO US8), the radio may drain the vehicle's battery. When a customer ejects a CD that is in the CD player and then pushes the CD back in within 25 seconds, the CD player does not recognize that the CD has been manually reinserted. When this happens, the radio/CD unit will continue to draw battery power after the ignition is turned off. This condition can be created at anytime (vehicle on or off), and will remain until the CD is ejected or battery power is lost.
Correction
Dealers are to reprogram the radio.
Vehicles Involved
Involved are certain 2008 model year Chevrolet Colorado and TrailBlazer; and GMC Canyon and Envoy vehicles equipped with an AM/FM Stereo with CD/MP3 Player (RPO US8) and built within these VIN breakpoints:

Service Procedure
Do not attempt to order the calibration number from GMSPO. The calibration numbers required for this service procedure are programmed into control modules via a Multiple Diagnostic Interface (MDI) or Tech 2(R) scan tool and TIS2WEB with the calibration update. Use TIS2WEB on or after 04/29/08 to obtain the calibration. If you cannot access the calibration, call the Techline Customer Support Center and it will be provided.
Service Programming System (SPS)
For step-by-step programming instructions, please refer to SI and the Techline Information System (TIS) terminal.
1. Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Only use approved Midtronic 165-PSC charger, a fully charged 12V jumper, or booster pack disconnected from the AC voltage supply to maintain proper battery voltage during programming.
2. Reprogram the Radio (RAD). Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
1. Connect the MDI or Tech 2(R) to the vehicle.
Important
Select J2534 MDI or Tech 2(R) Legacy Pass-Thru and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen. The J2534 MDI will reprogram the module in less time than the Tech 2(R) scan tool.
2. Select Radio (RAD) from the Supported Controllers screen.
3. Follow the on-screen instructions.
3. Using the MDI or Tech 2(R), clear all DTCs if required.
