Fail To Accelerate Problems of Toyota Yaris

1. Events leading up to the failure: on several occasions my car seem not accell properly-I would have my foot on gas pedal and it would not go any faster and the car made noise similar to overheating or fanbelt with vibration-but the car would slow down when applied brakes-after letting car drift for a moment the car jolted then seemed to be fine-also, a week prior to the failure there was a clicking noise coming from the general area of where there was a recal corrected on my car a few months ago-I'm not sure if that has any relevance-2. The failure that occured was: as I was trying to reach approx 50-60mph my vehicle failed to accelerate passed 40mph-I noticed that even when I pressed the gas pedal all the way down the car still did not accel pased 40mph then I noticed the lever on spedometer was not move from 40mph even while having gas pedal pressed all the way down-then I applied brakes and car did slow down but the lever on spedometer still was not moving from 40mph while breaks applied and car speed decreassing-there was a noise from engine similar to the sound of overheating or fanbelt and was vibrating- and then after letting it drift then it jolted and then seemed to be fine - that was the first time it happened with spedometer not moving and while I was on the highway trying to reach 50-60mph-consequence:as I was changing lanes-there was car behind me in the lane I changed into and that is when my car did not accel and stayed at 40mph-the car behind me almost hit into me after I changed lanes and I was heading toward traffic that I was needing to merge into at atleast 50mph 3. The problem has not been repaired-the dealership has not been able to simulate/diagnose the problem-my car is still there I am afraid to drive it-I returned the dealers car and left mine-they would not let me read the diagnostic papers before signing -I want to know if edr and the electonic throttle control system has been checked.
