How are you starting the car? With a key in the ignition, or remotely? The trunk opening puzzles me. I'm wondering if somehow you're bumping the trunk open button. It may have become sensitive.

That's strange. There's been a number of electrical problems blamed on a bad battery ground cable. I suppose that's always a possibility. Others have reported odd problems when the battery reaches end of life. But this particular one is a new one.

But then again, since you refer to the trunk as the "boot", I'm guessing you're not driving a US Cruze.
