“Unwanted acceleration happen more the 5 to 6 times. While driving in highway exit ramp my vehicle lurched forward while I was trying to slowdown. Dealership had the vehicle for more than 2 days and unable to duplicate the issue. Currently Toyota dealership informed they don't any know issues or condition like this. I am not very confident in driving this vehicle due to this experience.”
