2-incidents of sudden acceleration at freeway speeds: the first time the cruise was activated and on hitting resume the car took off on it's own. The coast function did not slow the car and turning off the cruise did not slow the car. I was in fairly light traffic and was able to steer and brake out of trouble until the accelerator returned to normal[the brakes only partially slowed the car because of the high speed involved]. About an hour later I was entering a freeway and at about 40-45 MPH the accelerator went to the floor on its own again and I had only partial control of the car's speed. The cruise was off this time and again after a few minutes and miles the engine revved down to normal on its own. Again traffic was fairly light so I was able to steer and brake through without a crash but in heavier traffic this would be a serious problem. The dealer test drove the car for about 18-miles but could not replicate the incident which is random and intermittent and their diagnostic tests showed these incidents never happened but believe me this is a real problem when these computers or electronic systems malfunction. General motors has opined that this is impossible which is a cover up since everything is controlled electronically. This is particularly dangerous since it happens at freeway speeds and the pedal goes to the max.
