I hadn't touched my car for about four hours and My mum and out the front of the house and said that my stereo was on and interiors lights were on. Sure enough they were. I had to use the central locking to get I to the car so it's. It as if unlocking by accident had caused the stereo to come on. Has anybody else had this issue? I will be taking back to Vauxhall because it's not right that it should be happening. It could go off during the night or anything !!

I've noticed something similar, I'll leave the car a few hours then open the boot, the stereo will come on for a second or two, though it's never been on long enough to investigate further.
Best to take it to the dealer, the Intellilink may just need updating.
