2012 Dodge Avenger cruise control problems

My 2012 dodge avenger caught fire under the hood while I was driving on the fwy. I could not stop the car because the brake became locked in place and I couldnt press it down with my foot. The emergency brake did not work. It was unsafe to get out of the moving car, so I was trapped in the car as the fire under the hood grew rapidly. I was able to get off at the next exit and with quick thinking, I used the curb at the end of the fwy off ramp to help me stop the car.

Will not shift into drive until speed reaches 45 - 50 MPH. Can not accelerate over 4000 RPM at any time. Unable to pass other slow moving vehicles at a reasonable speed. Have taken the vehicle into the dodge service center, explained what was happening, and was told "nothing is wrong with it because there is no sensor light on" .
