Battery drains after sitting for even a day or two. Replaced battery twice as it won't even charge after this happens often. Apparently from what I have read on this site there is an issue with Sirius radio needing update but mechanic claims they know nothing about it despite my forwarding information. They want to take the car which will only drain the battery as it sits in the shop. Why hasn't this problem been addressed by Volvo in the past 11 years? I am the third owner and quickly discovered why no one has wanted to keep this car! This does NOT reflect positively on Volvo by any means.
