Driving up an on ramp to an interstate highway, the car would not react to increased depression of the throttle pedal. Tool indicator warning light illuminated on the dash. I barely was able to pull off to the berm, almost rear-ended. This has happened numerous times since first occurrence on 6/11/15-6/12/15 and appears to occur only when I have the air conditioning on.

I was driving up the hill & slowed down for the speedbump. I started applying the brakes to turn right into the driveway but the car lunged forward, causing me to miss the driveway & turn into the yard. As I stepped on the brake the car continued to speed up so I screamed at my husband "james I can't stop the car!" he yanked the handbrake up but it didn't stop or slow down and the engine made a continuous high pitched racing sound. We crashed into the house, damaging it & breaking my left arm! The car was totaled. All this occurred in just a matter of seconds. Fortunately our family was in another part of the house and weren't injured.
