2007 Hyundai Santa FE drivetrain & axles problems

Park N Fly Mississauga Canada. Vehicle in parked position. Vehicle reversed from position and driven for 50-75 feet. Driver made a left turn and within two seconds the vehicle started accelerating on its own. Driver’s head and hands bounced off the steering for a brief moment and then returned. Engine could be heard revving continuously in an increasing manner. Nothing on the gas pedal nor was it manually depressed.

While coming to a stop the car started to accelerate on it's own. I put more pressure on the brake, but would not hold, I put the car into neutral and turned off the key. When I restarted it was ok but my air bag light was on. When I got home I parked and pressed the key remote to lock, the doors locked but the lights did not flash. I then restarted the car, shut it of and relocked. This time the lights flashed but after about 30 sec. The car alarm would sound.
