I have my 2012 JGC with push button start. Problem is not all the time but when I push to start it it will start for a second and shut right off. Seems the ignition is on but car not started. The dash is all lit up gauges fuel gauge temp gauge. Seems to be locked in on the accessory or ignition on. Try to start and no start. So I have to hit the pushbutton and shut off the whatever position its in and then try to restart and it will start. Would any one know what might cause this
