This is the second incident of unintended engine revving with this vehicle. This second incident occurred at approximately 4500 miles. Was pulling out of a parking space in "reverse" and came to a complete stop with my foot firmly on the brake pedal when, in an instant, the vehicle unexpectedly revved up while I was still holding the brake pedal firmly and the vehicle was still in "reverse". alarmed, I immediately put the car into "park". the transition into "park" was not smooth and the engine RPM went even higher. It sounded like one third of full throttle. My wife was in the vehicle with me. Once in "park", we put down the windows to hear how loud the engine was revving. Still in "park", I asked my wife to watch me step on and off the brake pedal at least three times, but the engine did not return to idle. I then kicked the accelerator pedal and the engine returned to normal idle. Acura client relations had a "field representative" check my vehicle. For the second time, Acura is claiming that no problem can be found with our vehicle.

Yesterday, after backing up, stepping on the brake pedal and coming to a complete stop, shifted into "park" with my foot still on the brake pedal. The engine unexpectedly revved up to what sounded like full throttle! I pushed the ignition button to stop the engine. After this one incident, the car has functioned normally.
