At times will not start no crank or nothing,but some days it would start like everything is normal. So when it didn't start i would jerk the key ignition back and forth until it started.

Occasionally starts but will immediately shut off . And will not run until you leave it alone for ten minutes. (I'm guessing the body control module resets) then it starts up and runs fine. Weather temp changes I noticed is a factor . Also if it doesn't start just leave the radio on and don't open the drivers door . Pull the key out of the ignition And then wait for the radio to automatically time out/turn off. Then it will start every time.

It has happened 2 x in the past 9 months, it reset by putting key in door to open it instead of the key chain unlock. Security light goes on more frequently now.
