| Description of the problem | 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. |
