Recently, I've been having two intermittent lights showing up. It started with the "light out" indicating that the left rear light is out, but it is not. That light comes on for a minute then goes away. In addition, I get a notification that my trunk is open... I've opened and closed it with no change in the light.

I'm assuming that these two share something in common, like a ground or something, that I should be looking at but does anyone have a recommendation for where to start looking?

Thanks.
