Two problems related to accelerator stuck have been reported for the 2006 Toyota Prius. The most recently reported issues are listed below.
Accelerator sticking on a 2006 Toyota Prius. It is not catching on the floor mat, which is the recall for that year. The car has 89,000 miles. This problem just started in the past month. I will start to accelerate, and it will just take off without warning. So far, it has popped loose and returned to normal. Most recent date is listed below.
Toyota Prius 2006. I pressed accelerator all the way down to accelerate and got stuck there. I was able to stop the car with the brake. It happens twice in July 2009. Once I stopped the car I checked if the floor mats have done so. The floor mats were not the cause. The accelerator was stuck all the way down even with the engine off. . . . And only after a minute or two of the car stopped and engine off did came the accelerator back. I brought the car to the dealers and they told me that it was the mat. I told them that was not the case. The dealer put some grease in the accelerator and did a few more things (cleaning around and the fuel injection I think). Since then I have avoided pressing the accelerator all the way down even when I need the power to accelerate at the entrance of highways and has not happened again. But there is definitely something wrong with either the mechanics of the accelerator or the electronics that somehow gets the accelerator stuck when you press all the way down. This should not happen and needs to be repaired.
