Hi new here, had drivers air bag squib replaced 12/16 , drive car every day normally. Car sat in garage for 2 days wouldn't start on 12/24 thought we left a light on, tried to get it jumped would not jump. Put trickle charger on it and 2 hous later it started up. Drove it for errands on 12/25 it would not start battery drained again, nothing open, on 12/27 charged it up took it in, battery tested good (new in oct) but low, starter good (replaced in June) , my guy warranted out battery put a new one in. Drove car on 12/28, 29, and 30. Tried to start it today 1/1 battery so dead could not even adjust seat. Put charger on, and car seems to be "on", charger clicks like trying to start, lights flash on and off, then clicking stops for a second, then starts again with lights going on and off, does this with or without key in ignition. Key fobs are in house more than 50 feet from closed locked garage. Tried to insert key and turn "off" car did not work. Still cranking itself afraid to leave charger on since it can't charge if its cranking and may screw up charger or start up with no one there. I am guessing that is the reason for the drained batteries. But why now?
