So similar issue fir me tonight. 12 jeep wrangler sport 6 speed. 13 ticks. Come out to parking garage and jeep starts to turn over then immediately completely dead. I think that's odd. Did I leave my lights on from getting lunch? I dint think so. So eventually I find a jump. Car starts but brake light is on, abs light, traction control light and dinging noise. Radio goes on and off, interior lights flicker. Start to drive home, speedo not working at all at first then just jumps around from 0 to 30 and back and forth. Get home and put in neutral and rev it a bit and it Seems to be running a little rough. Turn it off and try to restart and completely dead. Turning key dues nothing. No lights at all. Take key out, Make sure lights are off and get out. Notice the parking lights are on dimly and flickering a bit. Double check that everything is off. It is but parking lights still on. Go inside about 20 minutes. Come back to garage and now the headlights are also dimly flickering on and off. This is nota joke. They do this fir 2 or 3 minutes. I open the hood to look at the battery and when I open the hood the lights go off. Everything seems normal. Close the hood, get in car, dome lights turn on, car tries to start but battery just seems to weak. Almost turns over but not quite. Classic weak battery response and completely different than what it was doing before. Weird. Any thoughts? Just a battery? Jeep is 23 months old and 13 miles.
