Thanks for the advice about the light switches and will pass it on to the service manager (anonymously). I’ve had the car in to the dealership every time the battery has died (have lost track of how many times with each battery). The second battery had a dead cell (discovered when I had the car towed in rather than jump started). The third battery was installed last October–no problem until mid-April when it went dead and was replaced. The garage swears they’ve tested everything they can think of, including re-setting the motion alarm to “less sensitive”. (We never set this to begin with.) No aftermarket equipment. I keep hearing the comment that we just don’t drive the car enough. NEVER had this issue with our previous Subarus ('89 and '92). I have trouble believing that I’m supposed to remove some fuse when I plan to let it sit for a week or longer.
