Car Will Not Accelerate problems of the 2013 Jeep Compass

I was driving on the PA turnpike approximately 65 mph, when I stepped on the gas and the car would not accelerate. My car was basically coasting as cars and tractor trailers were flying by me at 70+ mph. I managed to get off the road safely, and all the lights on my dashboard were going crazy. Had the car towed to the dealership and they told me it's the "throttle body" - regulates the flow of fuel to the engine - electrical failure.
