Well I have a 350z which is nearly identical, and I know our cars are pretty much impossible to have a stuck accelerator because they use "drive by wire" which means they have electronic means of detecting pedal position and not a cable. You may have just panicked when you hit something and hit the gas.
Also, if they had this problem, they would certainly be recalled as this is really serious
