Accelerator Stuck problems of the 2007 Lexus IS250

I own a Lexus Is250, I pushed down on the gas pedal and it got stuck. I rammed into a car and hit it twice before the car would stop. I hit the car on the sensory going 35 miles per hour and my air bags didn't deploy.

I was normally driving on the road and on good weather conditions. My car accelerator pedal got stuck. The car accelerated very fast and was rapidly approaching a red light. I quickly reacted and was able to pull back the accelerator with my shoes and hand.
