My guess is that you may have had a bit of dirt in the SGS2's USB connector. The SGS2 senses what peripheral (dock, car mount, MHL adapter, etc.) is plugged in by detecting specific resistance values across pins on the micro USB connector -- a bit of stray dirt can throw off that detection, giving the impression that a peripheral (in your case, a car mount) is installed. Plugging and unplugging the charger may have cleaned the connector enough that you're no longer seeing the behavior.

Gently cleaning the connector with a soft brush and a gentle blast of compressed air should resolve the issue if it comes up again.
