Service bulletin PIC6151
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
Some customer may complain that their 2016 Volt does not charge on certain Panasonic public charge stations. The customer may also state that their Gen 12011-15 Volt would charge on these stations. The Panasonic Control Pilot signal is out of specification with respect to the signal characteristics as defined by Society Automotive Engineers Specification SAE J1772. These charge stations create an unstable pilot signal which is key to initiate charging. It takes this charge station longer than the SAE specification to provide the proper pilot signal and target voltage. However, the reason why this works with Gen1 Volts and does not work with Gen2 Volts is because there was a VICM microprocessor change between Gen1 and Gen2. The Gen 1 micro was running slower and was therefore more tolerant to signal overshoot (it naturally allowed more time for the Control Pilot signal to settle). The Gen2 microprocessor runs faster and is therefore more vulnerable to reading the Panasonic Control Pilot during the overshoot phase, before it has settled to a steady state value.
