All lights on dash came on, wouldnt drive

[GuyfromNY456]

Daughter just picked up a 2011 outback from the dealership. She was driving and at a stop light. When she took her foot off the brake to apply to the Gas, the car rolled backwards no matter how much she presses on the gas. Then, every single light on the dashboard came on. She shut the car off and then turned it back on, drive engaged at this point and she was able to get the car home, but now the brake light is flashing, the check engine light is on and the traction control light is on.
