Loss of acceleration after braking. vehicle will cease responding to the accelerator pedal after braking, will continue to go slowly (~20 mph) for 3-5 seconds, then accelaration will resume. happens at any time in any situation; brakes just have to be tapped to lose acceleration, has been happening since vehicle new.

As city street braking deceleration is ending, the engine suddenly surges and accelerates rpm. i must immediately apply hard pressure on brake pedal to prevent van from surging ahead and also immediately move automatic shift lever to neutral to disengage power train. after about 2 seconds the rpm acceleration will stop and return to normal. toyota dealer checked issue multiple times, finding no issues. this is a random occurrence that started shortly after purchase and continues to this day and i've come within inches of smashing into vehicles in front of me. i reported to toyota corporation but the ombudsman blew me off saying there is no known sudden acceleration issues. no offers to resolve from toyota. this has happened so many times, i can no longer remember the initial date and exact mileage this issue started to occur other than within the first 4 to 6 months of purchase. additionally the speed control was never activated when issue occurred.
