Hello,
My XC70 wagon is displaying a "low battery" message, just as it was about two years ago. I ignored that intermittent warning for too long and eventually got stuck in the Trader Joe's parking lot. I ended up having to replace the battery and thought I'd be all set for years, but now it's starting again. I noticed today that the rear door didn't want to open as easily as it usually does, so maybe that's another sign of low power? Shouldn't a battery last longer, and shouldn't the alternator (if there is one) charge it whenever I drive the car? Maybe I don't put enough miles on it? Thank you!!
