I had a similar problem 3 or 4 months ago but I was stuck in park , had to have it towed to the dealer ,turned out it was a connection in the main wiring harness came disconnected, $800 later and a new batt. fixed .hope you have better luck.

Go to my user name ( Sherbercars at the top of my post ) click on and it will bring up all my posts , go along until you find post stuck in park and wont start. Bernie

 

Another way to say this is hold the start button down, wait for the ding, then press progressively harder on the brake pedal until it starts.
