NHTSA Complaint #11476405 — 2012 FORD FOCUS

I bought this car in February of this year, and the problems were present at purchase, I have brought it in and had them looked at but unable to determine what was wrong. The car sometimes stalls out whenever parked, or idling. Every time i put gas in, then start it, the vehicle will start then immediately stall. I have to start it and push the gas to keep it from stalling and quickly put into drive and his the gas to get it from stalling when i try to drive away. While starting the car the RPMS go very high and reves as if someone was pushing the gas. The hood display on the dash always says the Hood is open. This has been present since start.
