Service bulletin PIP4686D
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
This Preliminary Information communication provides information to the technician about vehicles that have various 2-Mode Hybrid issues. Some vehicle may have service hybrid system lamp that comes on with a Diagnostic Trouble Code P061B set. Technician will need to take a snap shot of the Electronic Brake Control Module and call General Motors Technical Assistance Center for further assistance. Some vehicles may have a combination of engine stall at a stop, lacks power on acceleration, surge while driving, engine flare, transmission slip, poor or lower fuel economy or reduced EV range/limited electric propulsion since completion of recent programming. Technician will need to perform a Charge Procedure. Some vehicles have Diagnostic Trouble Code P0BBD stored without Diagnostic Trouble Code P061B or P0AFA. Technician will verify that the Drive Motor Battery was not run low on charge due to a no start concern.
