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 !!
