Ever since I've had my XC-90 I've had intermittent battery drains to the point where the car won't start. Happens infrequently, maybe once every three or four months. Happened again today. Doesn't seem to be directly related to how long the vehicle has been sitting, though I haven't really tracked that. However the vehicle was last driven two days ago in this case.
Had the battery tested last time this happened, and it tested like a new battery. No issues identified. Tried a search on the issue and came upon this: https://forums.swedespeed.com/showthread.php?452265-Disablling-Sirius-Satellite-Draining-Battery The claim is that the Sirius tuner in the radio will continually scan for a signal regardless of whether the car or radio is on or not. Apparently a software update is available to fix this but may have a cost. Seems suspect to me that the radio would be doing this when not on. And it would have to be a pretty significant current draw to drain the battery in a day or two, which seems unlikely for a digital radio receiver. Anyone heard of anything like this on any other cars?
