There appears to be something dangerously wrong with the transmission. I have experienced this randomly, maybe a dozen times, over the last week since I have owned the car. It takes up to two seconds for the car to respond after pressing the gas pedal. This has happened when slowing down and then having to give the car gas, again. Other times it has happened from a stop or an idling roll. There is a significant hesitation. This does not happen every time, which makes it that much more dangerous - being unpredictable.
2010 Toyota 4runner fails to accelerate intermittently when gas pedal is pressed. Has failed to respond to accelerator for a full three seconds at one point. Commonly, delayed response lasts 1-2 seconds. Took vehicle to dealership. They were unable to duplicate the problem. Service tech said this could be caused by the electronic traction control. Issue occurs regardless of traction conditions.
