On January 2nd, 2012 on 2-separate occasions the engine accelerated to almost 6000 rpm while I was stopped or nearly stopped while parking the car. The car was in drive and I had my right foot on the brake but the engine acceleration happened very quickly and on the second incident the brakes were not holding the car. I was able to get the trans into neutral untill the acceleration died down to the normal rpm. On the second occasion I shut the ignition off 2-times before the accelration stopped. I have had this problem with prior cars and the manufacturers have had no system in place to diagnose the problem and because it is a random event it is almost impossible to replicate. Because of litigation in accident cases I believe the manufacturers are in denial of this electrical problem.
