I haven't driven my GLC for over 24 hours but this evening when I looked out one headlight was on. The car was locked all day. I don't know how long it was on but it couldn't have been on for more than an hour.
I locked it again with the key and the light went out. Has anyone experienced anything like that?

Did you leave your blinkers on when you last shut down your engine? Seems like you had unintentionally activated the single side parking light.

There's some incidences of it happening. Seems to be related to the LED lighting systems. Have the software updated in the headlights and see if it corrects it.
