I had two events. one while driving at 20 mph in my neighborhood and straight line driving and car suddenly accelerated. i threw car in neutral and stepped on gas hard for a second and cancelation stopped. then five minutes later, while making a left turn, same exact event took place. i did the same thing. i had the brakes on hard and no stopping car. first time car has done this and i am only driver for six years. brought to acura and they sent a corporate mechanic to check and said they found nothing. just got car back. a little scary.
