I've had this problem before. A quick fix was to have someone jump my car for me and I was good to go. Yesterday, the problem started again when I had to disassemble my driver side door to put the window back on track. After putting back the door panel, I tried to start my car but a message came on the dashboard that I've never seen before, "Service Airbag". After I saw that, I turned the key to start the car, a couple clicks but didn't start. So to 'fix' this problem, I had to jump start my car and it worked. Unfortunately, I tried to turn the car back on but I received the same message and it wouldn't turn on. The electricity started to faded, so I figure the problem was I needed to replace the battery. I replaced the battery - the electricity works but I still get the same message and the car won't even turn. Without the keys in the ignition, the radio is turned on? Not sure what the problem is here. I figured it is either the alternator or the starter. I see some other Cruze owners have had the same problem as I am. GM needs to figure out this problem.
