After work tonight, as I was walking to the Buick, I hit the unlock button. The doors unlocked and the headlights lit up, as usual. I got in and turned the key, and nothing. Here's the strange part: the key was stuck in the ignition. I could turn it between what I think was ACC and START but no dice on actually starting it. Stone dead. At this point, I thought the ignition switch was bad. But on a whim, I tried to turn on the dome light. Nothing, zero, nada. I try and unlock the doors again. Nothing. So I fold down the backseat and get the NOCO jumpstarter I got for Christmas. Using that, she fires right up (and before I start it the dome light/radio come on). I disconnect it and drive the 4 minutes home. No issues. Immediately upon parking it, the battery voltage on the DIC read 12.5. It was 20 degrees or so, but we've been in a prolonged cold snap (single digits and below.) However, the car was in a heated garage each night. And I put it on a battery maintainer about once a month or so. The car is short-tripped, though. Just last month, it tested at ~500/660 CCA, a recommeded "fail" by one CCA (it's a 33 month-old JCI ACDelco with a 30 month warranty).
Any ideas?
Just a dead battery?
