1 Accelerator Stuck problem of the 2007 Toyota Prius

Failure Date: 06/19/2015

After speeding up to pass another car on a slight upgrade (2 lane country road), my Prius continued to accelerate. I could not slow the car down to the speed limit using the brake pedal. For about fifteen minutes, I kept trying to slow the car down, looking for a place to pull over where I wouldn't hit anything. The accelerator pedal was not stuck & no floor mat was touching either pedal. The only way I could stop was with the emergency brake. I thought the car might explode, but later realized the smoke was pouring out from my brakes. I maneuvered to the berm of a bridge over a lake, just before the road went down to one lane for construction. Then I turned the car off. Ten minutes after this ordeal (vehicle was stationary), I restarted the car, but the engine began racing again without any touch on the gas pedal, so I quickly turned it off. Luckily, I hadn't collided with anything.

3 Accelerator Stuck problem of the 2005 Toyota Prius

Failure Date: 11/24/2010

In December 2010, 2005 Toyota Prius was taken to dealer for pedal modification as part of the floor mat accelerator pedal entrapment recall. The dealer did not explain that pedal was actually being shortened by cutting off 1/4 inch at the bottom. After the recall modification was completed, accelerator pedal became stuck on after-market floor mat that had been in place in the vehicle since December 2005. Dealer did not mention this possibility at the time of the recall fix. (prior to modification, vehicle owner had checked to make sure that floor mat was properly anchored and that there was no way for accelerator to become trapped. ) in this case, the modification intended to prevent floor mat entrapment actually caused the pedal to become stuck.

4 Accelerator Stuck problem of the 2004 Toyota Prius

Failure Date: 07/13/2010

2004 Toyota Prius accelerates due to gas pedal getting stuck in the floor mat. This morning I was driving my Toyota Prius 2004 that I bought from the original owner who mentioned all recall issues were addressed by Toyota dealership. He mentioned the dealer shaved off the gas pedal to make it shorter. But today, while on I 495 going eastwards just before entering the hov lane, I pressed the gas pedal all the way down to over take another slow vehicle. The car engine kept raising noise, and car started to accelerate on its own. I braked, the car slowed a bit but engine kept running fast. . . I realized this is potentially same issue that people reported on press and with lot of struggle trying to brake and slow down, realized and put the car into n, neutral position. I am lucky to know this from media reports, otherwise I would have been another dead guy on a Prius! while I was still on highway, needing to maintain speed I put the car back on drive mode, d and the problem continued. I realized, I can lift the gas pedal with my left foot, and succeeded in untangling the pedal from the floor mat. After I did that it was fine. I arrived at work, but with extreme shock and disappointment. I am wondering how this problem can still remain after a recall repair is done on this vehicle. This is completely unacceptable and my life was in total risk and I survived today purely because of my technical skills and knowledge about this car issue. I am an engineer in profession, a mechanical engineer with a masters degree and I understood how to react. If it was for my other family members in this situation the outcome would have been totally different. I am very very disappointed with Toyota corporation and also with you, the NHTSA for not making sure that all Prius out there are safety compliant. This is really terrible ! . . . Because its a known issue, and old issue that should have been corrected. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

5 Accelerator Stuck problem of the 2007 Toyota Prius

Failure Date: 05/05/2010

The contact owns a 2007 Toyota Prius. While driving 45 mph, the accelerator pedal became stuck and the speed increased to 55 mph. The contact was forced to kick the pedal in order to release it; however, within a few seconds it became stuck again. The vehicle slowed down as the contact continued to depress the brake pedal firmly. He pulled over to the side of the road and turned off the engine. The vehicle was towed to an authorized dealer where the repair for the recall on the accelerator pedal was performed. The dealer did not explain the repair in detail. He called the manufacturer but was offered no assistance. The current and failure mileages were 31,541.

7 Accelerator Stuck problem of the 2005 Toyota Prius

Failure Date: 03/03/2010

Last evening 3/3 my 2005 Toyota Prius experienced a stuck gas pedal causing me to go in and out a ditch then across the road and hit a sign prior to my finally being able to get it into neutral. Since neither Toyota total care/roadside assistance or the Toyota of bowie dealership would tow it to the dealership I placed a claim with my insurance company usaa. When I got to the dealership they were extremely unhelpful saying I had to make a complaint with Toyota as they were not Toyota but an independent dealership. They did not want to look at it since it looked fine on one side but they didn't even want to hear about the under carriage. The car is there waiting for my insurance adjuster to look at it. They also advised that I needed to complain to NHTSA. Gov since there's nothing wrong -- without even looking at it they said this. I just had the car in the 90k and then for electronics problem since over 7 times if you drove the car then shut it off then try to restart it 5 minutes later all the lights would come on but you couldn't start the engine or do anything until the electronics unfroze. They said it was the battery and the remote but I disagree since they said to make sure everything is off before you turn it off. I ask why and they just said that?s how Toyota says to do it. Today one of the first things they asked was if the defroster was on or other electronics. As you can imagine I am extremely upset!!! to ask me to drive it to see it does it again was an extremely inappropriate response to my situation.

8 Accelerator Stuck problem of the 2009 Toyota Prius

Failure Date: 02/28/2010

This is extremely urgent! I own a 2009 Toyota Prius with no floor mats in it at all and the gas pedal stuck once a few days before the driver in California(2008 Prius)was stuck speeding on highway and stopped by police. After seeing that story, I was compelled to share my story. Toyota refused to help me saying my year wasn't in recall list. It happen the same way it happen to him in calif. I was accelerating on highway to pass driver and it stuck for 20 seconds then unstuck. I slammed on brakes which didn't help much. I started going upwards to 70 mphs with braked to the floor. There were no floor mats in car at the time. I'm afraid I will be the next Prius that may cause accident or even kill someone. Please help! Toyota refuses to see my car! I don't know what to do. . . Maybe I should go to the news. I'm scared!.

10 Accelerator Stuck problem of the 2008 Toyota Prius

Failure Date: 02/18/2010

I have a 2008 Toyota Prius which has a surge problem upon start-up. My wife and I are concerned because this has occurred several times in the past. We honestly believe that the problem lye`s in the computer and not in the gas pedal getting stuck, due to the fact that we do not have to compress the pedal on start-up. In fact, we usually keep our foot on the brake in case it lunges again.

11 Accelerator Stuck problem of the 2008 Toyota Prius

Failure Date: 02/05/2010

My 2008 Toyota Prius gas pedal stuck and pushed forward against my control, and I slammed my foot on the brake and gas pedal at same time and it stopped. I am reportint this to the Toyota dealer at priority Toyota in chesapeake virignia right now and they said because they can not reproduce the incident they can't do anything, but for me to call Toyota 1-800-331-4331 and report it, I did, and talked with a representative, and he said all he can do is put it in the case file, and if I wanted to I can report it to NHTSA. I will not become a death statistic to prove the problem occurred.

12 Accelerator Stuck problem of the 2009 Toyota Prius

Failure Date: 01/24/2010

November of 2008 I bought a 2009 Toyota Prius. Since then I have experienced 4 incidents where the accelerator became partially depressed causing an unprovoked acceleration, the most recent being on Sunday, January 24, 2010. I contacted the Toyota dealership where I bought my car the very next day (1/25/10) and reported all 4 incidents. I was told by the Toyota representative that there was nothing that they could do. I was given an 800 number to call to report my concerns. I received an automated reply telling me to call back at another time. I have been calling back but to no avail. I live in the high desert where it sometimes snows and the highway can get icy during the winter. I fear for my safety and the safety of other motorists if I continue to drive my Prius due to the unpredictability of the accelerator sticking. I am retired and live on a modest income and cannot afford to pay for the repair of the accelerator problem. In the incidents that I have described the sticking of the accelerator was not caused by the floor mat or any other accessories.

13 Accelerator Stuck problem of the 2009 Toyota Prius

14 Accelerator Stuck problem of the 2008 Toyota Prius

Failure Date: 12/12/2009

Approximately 2 months ago I received a letter from Toyota recall due to potential for car mat causing accelerator to stick open. Letter indicated they would notify me "as soon as a campaign remedy is available for my vehicle. " letter further indicated that I could submit a complaint to you "if you believe that Toyota has failed or is unable to provide a remedy without charge or within a reasonable time". . I have not received a notice about any "remedy campaign". This is not timely and I do not believe they are able to provide a remedy. As you are aware, since that time, there have been numerous reports of "sudden unexpected acceleration" in these vehicles. It is also apparent that the floor mat has had nothing to do with most, if not all of them. It does not appear that Toyota has any intention of notifying me of any "remedy" as they are not acknowledging any other acceleration problem. Every time my wife or I drive this vehicle we are risking this happening to our vehicle and Toyota is not doing anything in a timely manner.

15 Accelerator Stuck problem of the 2009 Toyota Prius

Failure Date: 11/06/2009

Accelerator sticking on 2009 Toyota Prius.

16 Accelerator Stuck problem of the 2005 Toyota Prius

Failure Date: 11/01/2009

I have not had an accident, but I have had sudden accelerations or surges on my 2005 Toyota Prius on a number of occasions. They have been brief, and the vehicle has not reached a high speed, so I was not too concerned. I just assumed the problem would be addressed by regular servicing. These had nothing to do with the accelerator being stuck. A friend's camry accelerated and crashed through the wall of her garage. She also believes this was not related to a stuck accelerator pedal. I urge you to revisit the potential of software problems causing sudden acceleration on Toyota vehicles.

17 Accelerator Stuck problem of the 2007 Toyota Prius

Failure Date: 10/28/2009

I have a 2007 Prius and the accelerator has stuck 3-4 times on the highway.

18 Accelerator Stuck problem of the 2009 Toyota Prius

Failure Date: 10/22/2009

Hi. I have a 2009 Prius that has had 5 separate episodes of accelerator sticking. Since I bought the car 11-09. The last incident was oct 09. No floor mats in the car. It has only occurred when, at 55+ mph, I accelerate rapidly to pass another car. The accelerator felt like it had remained depressed with continued speed acceleration. This did not respond to pushing down on or pulling up on the accelerator, or to depression of the brake pedal. The episodes lasted less than 10 seconds and resolved spontaneously. I was unable to identify why the acceleration suddenly stopped, but when it finally did stop, the speedometer indicated over 70+ mph. I pushed continuously on the brake pedal to slow the car during the episodes, with only minimal slowing of the vehicle. I have not taken the car to the dealer yet, as everything in the media indicates that they deny any problems with the care and have had no explanation for the events except the car mats.

23 Accelerator Stuck problem of the 2008 Toyota Prius

Failure Date: 08/13/2009

Toyota Prius, 2008, involved in accident , August 13, 2009 when it accelerated rapidly out of control after being at a stop sign for 4 minutes stopped in a line of traffic, hitting car in front and being very difficult to bring to a stop. Went from 0 to 45 mph very quickly and hard to stop . Toyota has not responded to complaint or my insistence that it be fixed. Was deemed by judge who heard the appeal of ticket to be a mechanical failure. First accident for me in 48. 5 years of driving. Initially I thought it was brake failure, but after the info came out, it matches exactly the accelerator sticking that has been described. Filed complaint with Toyota in October and have not heard back. Haven was the contact, claim number at Toyota is #0910145720. Also notified dealer where it was purchased and have not heard from them. Was assured I'd hear in January and got a letter indicating that I should take the floor mat out. It happened again in November of 2009, although I immediately recognized it and got the car stopped quickly. I'm now afraid to drive it but need my car to work.

24 Accelerator Stuck problem of the 2006 Toyota Prius

Failure Date: 07/15/2009

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.

25 Accelerator Stuck problem of the 2007 Toyota Prius

Failure Date: 06/03/2009

The contact owns a 2007 Toyota Prius. The contact stated that whenever she was driving the headlights came on and shut off intermittently. Occasionally, the headlights would not come back on for fifteen minutes after they shut off. The accelerator pedal also began sticking to the floor; however, there were no floor mats in her vehicle. The dealer informed her that for $400 they would replace the bulbs in the vehicle. There were no related recalls. The VIN number was unknown. The failure mileage was 75,850.

26 Accelerator Stuck problem of the 2008 Toyota Prius

Failure Date: 04/10/2009

Needing maximum acceleration to avoid being struck from behind, I thrust the accelerator to the floor in my '08 Prius. Safely avoiding a possible collision, my auto continued to accelerate. The accelerator was stuck in the full down position and could not be budged either by hand or by repeated stomping to release it. I made sure the floor mat was not interfering with the accelerator, which it wasn't. I braked hard and turned off the 4 lane street to the right and was about to turn off the engine when it released as rapidly as it began. I reported it to Toyota at my next oil service - but they had no prior experience of this type of complaint. I have since refrained maximum acceleration - but am afraid to let anyone else drive my auto. Now that I am aware that there is no direct mechanical connection to to investigate or correct in the fuel system, but instead an electronic one, ("fly by wire" like the new commercial jets), I am even more on edge. Thank god, the Prius is underpowered. In a more powerful auto, the engine would have overpowered the brakes and led to a possible disaster. Electronics malfunction sporadically! please investigate!!!.

27 Accelerator Stuck problem of the 2008 Toyota Prius

Failure Date: 01/15/2009

Accelerator sticking on 2008 Toyota Prius - 5 to 10 times. I took it to the dealer (beaver Toyota - santa fe, nm). The first time they said they did not know what it was since they could not reproduce it. The second time they said it must have been because of the floor mats. The third time I called they said the floor mats even though I had removed them. I am unsure of the first date although it should be in their records. It has not happened in about 6 months. When it happened I would put my left foot on the brake and "pry" up the accelerator with the front of my right foot. The floor mat never seemed to be involved. My dates in this report are approximate.

28 Accelerator Stuck problem of the 2005 Toyota Prius

Failure Date: 12/07/2007

My Toyota Prius (2005) gas pedal stuck. I was taking my wife to the hospital with a heart attack. We were going down a ramp and it stuck wide open. I kept pushing the start buttton and it quit. I called the Toyota dealer and he told me to remove my floor mats. I do not think my floor mat had anything to do with it. It has not stuck since.

31 Accelerator Stuck problem of the 2005 Toyota Prius

Failure Date: 05/05/2007

I love my Prius but a different story here, I think. I bought a new 2005 Toyota Prius. When it was approximately 2 years old with approximately 40 thousand miles on it (3 years ago) the gas pedal stuck and it was not related to a floor mat. I was accelerating getting up to the 55mph speed limit while also climbing a hill going out of town into the mountains. When I crested the hill and let up off the gas it just kept going. It was quite lucky that it happened on a straightaway just before the mountain curves and drop offs. As a lifelong professional driver with experience operating just about anything my first learned reaction was to dig my heels in and pull the floor mat back, it's happened to me in other vehicles. I glanced down and there were no obstructions at the pedal. My severely disabled son was with me. Automatically, I started kicking the gas pedal. After several kicks it slowed. No problem since. Never reported the incident. Just figured a weird glitch. Had not tried brakes yet, nor neutral, it's a different kind of car, a bit scared to try to turn it off while going down the road. I had already spotted a decent place to ditch the car with minimal damage. I had reached 75 to 80 mph when kicking the pedal stopped it. It's a computer thing.
