this happened to me in November, the light stayed on for half a day, it turned off on its own. today, it happened again. it stayed on. while running around today, i was in a parking lot and our mazda 2, 2012, 18,000 miles. while having the light stay on threw out the day, now it wont start. it cranked for 10 or so seconds and then finally started. this was NOT a low battery issue as we have never had a low battery (slow start) before and it did not sound like a low battery, once it started, it starts again fine, also hinting at not a battery issue.
