I'm having a similar problem with my trunk latch. Makes the loud noise with the key fob and the release button inside the car. However, the latch doesn't stay closed, it actually does the opposite, and doesn't like to re-engage when I try to shut the trunk. I get the light inside too that says a door is open. I was just wondering if the trunk adjustment held and corrected your problems? If so, I'll get the trunk adjusted. Thanks.
