Condition: Some customers may comment of a full charge level NOT indicated on the instrument panel (IP) charge level indicator after a complete vehicle charge event. The top indicator bar will not be illuminated.

Cause: This condition may be caused when "Hill Top Reserve" is turned ON. Hill Top Reserve enables the regenerative braking efficiency to be maximized when driving from higher elevation immediately after charging. Please refer to the Owner's Manual for more information.

Note: When turned on, this feature will stop the charge before the battery is full, allowing space for energy from regenerative braking.

Correction:Check to see if the Hill Top Reserve is turned on. Press the Green Energy button > Energy settings >Hill Top Reserve. Press the on/off button to activate or deactivate.

Wait. So GM just issued a service bulletin to tell people that if you set the car to not fully charge the battery, the car may not fully charge the battery??

I would have hoped that drivers would be smart enough to figure that out... :)
I believe their concern is that the setting might have inadvertently been set to ON, creating a perceived charging condition.

The fact that a bulletin has been issued, actually indicates there HAS been dealer visits for exactly that occurance
