Toyota Prius 2007 -- while stuck in heavy traffic, my car lurched forward and struck the car in front of it, which in turn hit the car in front. My foot was on the brake since traffic was at a standstill. Applying the brake harder did not stop the car in time to prevent the accident. There were no injuries. This never occurred before. The car has 19,000 miles. Spoke with Toyota dealership (smithtown Toyota). They denied that there is a problem and said we had a simple accident. Toyota said that this problem does not and has never existed.

The contact owns a 2007 Toyota Prius. The contact attempted to park the vehicle into the residence garage, driving at approximately 2 mph. Suddenly, there was an unintended acceleration. The brakes were engaged and the vehicle continued to accelerate causing the vehicle to crash into a closet in the garage. The contact suffered injury to the neck area. The vehicle front bumper sustained damages. The vehicle was taken to an authorized dealer where the technician was unable to duplicate the failure.

Yesterday I was driving back from dropping off my son at school, getting on the freeway, my gas pedal was about 1/2 way depressed, the next thing I know the gas pedal is leaving my foot as if in cruise control and flooring itself, the car engine is racing full speed, fortunately I had run this through my head before, and I was competent enough to apply the brakes as hard as I could, put the car in neutral and safely pull off the freeway and turn off the car. So I was towed into Toyota, given a loaner car and told that someone from the factory would come out to run some tests. First let me state, that after this was over I did look down to see if my floor mat was a factor in this, but also knowing that the pedal had left my foot and headed for the floor, the floor mat was a good 2 inches from the pedal. So this morning Toyota calls me to say that they have determined that it indeed was my floor mat, no doubts in their minds about that, so they have given me a new floor mat and told me my car is fine. There is no doubt in my mind that this is an electrical problem, not a floor mat issue.

Summary: My car began accelerating while I was in park. I own a 2007 Toyota Prius. Two days ago, I drove to my destination, pulled into a parking spot, and turned off the car. I was early, so I turned the car back on (so I could listen to the radio while I waited). The car was in park and I did not have my feet on any pedals. The car was on for less than a minute when it began to drive forward. I both heard the sound of the motor engaging and visually processed that the car was moving. I immediately stepped on the brake hard and the car immediately came to a stop. My 4-year-old was distressed because the rolling and hard stop made a big jolt. The car was still in park. I released the brake pedal and the car stayed still. I do not know if this is related, but my car headlights randomly turn off while I am driving. If I toggle the switch off and back on, they always come back on. I took it to the local dealer, where the repair guy told me they frequently see this problem, and all they do is replace the headlights (which made no sense to me, because the bulbs aren't burned out). I would say this problem happens about once a week.

1. my partner left work at @ 4 pm and started to drive home. It was a clear day with no precipitation. He was about a mile away from work proceeding West on NJ state route 561 when he came to a stop 1-2 feet behind a truck at a stoplight. He had his foot on the brake. 2. he was caught off guard as the car accelerated forward into the truck ahead of him without his doing anything to the accelerator. Damage was caused to the trucks bumper and to the Prius' bumper and hood. We had never had this occur in the car and had no other problems prior to this incident. 3. in the split-second he had to react, he jammed his foot on the brake and tried to deploy the P button on the dash, but the P button did not engage nor light up as green. A police report was made and the car was driven home. The local Toyota dealer, where the car was purchased and serviced, was contacted and they asked us to contact Toyota "experience, " and we gave a full report and received a case #: 1004081978. We then brought the car to the dealer's body shop the next day and awaited our insurance claims adjuster and the "experience" team to come and get the data off the computer to see what might have caused the accident. We will have the physical damage to the car repaired (damage to bumper and hood) as soon as the "experience" team is able to get the data.

I have experienced two episodes where my 2007 Prius accelerated uncontrollably. One was while backing out of a driveway by my classroom onto the street. I put my foot on the accelerator and the car literally took off backwards like a rocket. I removed my right foot from the gas pedal and applied the brakes--nothing happened!! I ended up with both feet on the brake across the street in parking spaces by the library. This happened Dec. 22 at 2:15, we were dismissed early for christmas break, if it had been any other day this street is used by teachers to transfer elementary students to the library for the after school program. My husband called the Toyota dealership and reported this, he was told our car was not on the recall list. The latest incident was last week, April 7 at 7:35 in the morning. I pull into the school parking lot driving very slowly to my parking space, I start to turn into the space, I removed my right foot from the gas, and for the second time it takes off like a rocket and does not react to brake application. In front of my parking space is a drop off and then a concrete block wall, I turned the wheel sharply to the right to avoid these, did a partial donut turn, ended up once again with both feet pressing the brake as far as possible. After I had caught my breath, I looked around, no one was coming into the parking lot so I slowly released the brake, carefully put my foot on the gas, the car responded normally, and I pulled into the parking space. The Prius is now at the dealership where they say the car isn't displaying any problems--of course it isn't, not until next time. We stated that we would not pick up the Prius until it was fixed, so now we are waiting for Toyota's new smart team to come. Honestly, I know that if my foot isn't on the accelerator, the car should not take off like a rocket!! this is a danger not only to myself, but to anyone else on the road with me. I've been fortunate twice, but what about next time??

I have been driving a 2007 Toyota Prius since July 2007. The hid headlights switch off automatically while driving. Sometimes the left hid switches off but the right headlights stays on. The headlights turn off but the display from the inside says that headlights are turned on. The headlights come on if I turn the headlights off and turn them back on then both of them are working till they switch off again during driving. Almost got in a T-bone accident when the other driver did not see me. If I am driving using cruise-control, the car seem to speed up a bit just for a sec a or two when you initially apply brakes.

I am writing to explain two problems I have had with my Toyota Prius. I want to have a documented of report of these problems in the event that they result in a serious accident, as I fear they might. I have experienced these problems on a number of occasions. The first problem occurs whenever I drive over rough or uneven payment. When the traction control kicks in, it feels as if the car is surging and it is necessary to step on the brake, sometimes with both feet, very hard in order to get the car to slow down or stop. I have taken the car in for this problem a couple of times. I have driven cars with traction control in the past and never felt the surging that occurs with the Prius, when driving other cars using other traction control systems. The other issue with the car is that occasionally, when accelerating, my normally silent Prius makes a loud revving noise. Whenever I hear this noise, I immediately take my foot off the gas. Thankfully, so far, the noise stops and the car slows down. The noise does not occur every time I accelerate, but it seems to be happening with increasing frequency. I am not sure if other Prius owners, especially those who have been involved in accidents, have reported this issue or noticed the revving noise prior to their accidents. But, I thought it might be an important piece of the puzzle that should be reported. I hope this information is useful. Quite honestly, I am a concerned each and every time I get into my car. But, with a year remaining on my lease I have little choice but to engage in what I feel is increasingly a game of Toyota owner russian roulette to get to school and do all the things I need to do.

1) two times my car has accelerated on its own, and I had to feather the gas pedal to get it to stop accelerating, which took under a minute to correct. 2)when braking the car, if you hit sand or a bump which causes the slippery light to come on, the car transistions from generating power, to all brakes, at which point the car accelerates as there is an interruption and a short period of time where there is no breaks. 3)when you are coming to a stop such as at a bank drive-thru, when placing the car in park while only the electric system was running, if the motor turns on while still in park, the entire car launches forward 1-2 feet, extremely dangerous.

My 2007 Toyota Prius was in park, engine running. I then pushed on the gas and the pedal stuck. I turned the car off, and the engine stopped revving. I then turned the car back on and the car ran fine. I am presently in S. Carolina and will drive to Canada next week with my two children, so am very concerned about getting in the car. What should I do?

Just completed a left turn behind another vehicle. The other vehicle then slowed to make an immediate left turn into a gas station across the road. I was gently applying the brakes to keep my following distance (10ft, traveling about 8mph). The other car suddenly applied the brakes harder to turn, when I pressed harder there was no reaction until I hit the other car, at which point the brakes engaged and I stopped.
