Had it happen to me a couple times already and I was able to get it to turn over after waiting about 5 minutes. Then get out of the car, lock it, unlock it, then open and close the door about 5-6 times or so. I was told it resets the fuel pump when you do that and allows for more fuel to be circulated. Then just hit the start button and it might work.
First time it happened to me I had about 3 dots and it didn't turn over until someone brought me more gas. Second time I had about 5 maybe 6 dots and then it worked. Good luck to whoever else encounters this damn problem
