When stepping on the gas petal one of three things happen. 1. Normal acceleration which you expect after 60 years of driving and which we obtain from a 2014 lexus rx350 that we own. 2. Hesitation of between 1 and 5 seconds before acceleration begins. 3 excessive acceleration ( surg of acceleration much more than expected). This excess acceleration may happen after the hesitation or there could be "normal" acceleration after the hesitation and happens when accelerating after being stopped.. The hesitation and excess acceleration can be from a stopped position ie stop sign or traffic light or while moving and normal speeds. There seems to be a consistent hesitation at the 60 to 65 MPH when attempting to accelerate on highway. At 70 MPH everything seems to work as expected. The surging and hesitating seems to be at lower speeds and and when making turns in city streets and moving up or down hills and in parking lots when moving out of parking spaces, but it happens at all speeds up to 65 MPH. The cars has accelerated with out depressing the accelerator - this could have been a delayed acceleration after pressing the accelerator a half block before. This happened with a lexus representative was in the car with me - I was driving so he could not tell if that actually happened or if I accelerated. Starting in early 2019 we have told lexus when the car was serviced( twice yearly that the car behaved in this manner. Each time that have told us they did not re-create the described behavior and the car was performing as designed.

I tried accelerating on the highway (pch in santa monica, ca) while traveling forward at about 45-50 MPH, but the vehicle hesitated. This is the forth time there has been a hesitation in acceleration since owning the car, but this time there was a message on my dash. The message stated that there was "an obstruction with the pedal and acceleration was retarded." I later looked down at the pedals felt around the them, but found nothing obstructing. At the time, the vehicle had less than a quarter tank of gas but not low enough for the low fuel warning to come on. After driving about 15 more miles - the low fuel warning came on. I have always put premium fuel in the vehicle and my wife doesn't put gas in the vehicle. A recall was recently performed pertaining to the fuel pump at the dealer - pertaining to low
