My wife and I were driving down a residential street approaching a stop sign. There were two cars stopped at the sign. Several hundred feet from the stop, I took my foot off the accelerator. The car did not slow down. I stepped on the brake. The car did not slow down. I stood on the brake as hard as I could. The car did not slow down. I said to my understandably alarmed wife, we're not stopping. And we didn't until we smashed into the back of a tahoe stopped at the stop sign, doing major damage to the prius that rendered it undriveable and perhaps totaled. My wife has a very sore back that I am hoping starts to feel better today or we will have to schedule a doctor's appointment.

I pulled my toyota prius into my driveway, stepped on the brake, opened the garage door and waited for my husband to get out of the car. He opened the passenger side door and started to move his foot out the door but before he even got one foot out, the car surged ahead and ran into the garage, pretty much destroying all the storage units on the right side of the garage. My husband thinks the car was going between 35 and 40 MPH. Since my accident there have been two other incidents of toyotas accelerating independently in palo alto. One ran into a house on park avenue, destroying the front wall and front door of the house. A few days later, a toyota ran over a curb, across a lawn and into a corner of a house on north california ave. Both of these incidents were reported to the police unfortunately, I cannot get the name and contact of the other two drivers because my name is not on the police reports. My questions are these: is there any legal way to get the information about these other 2 drivers? Also, someone told me they thought there is a class action suit out against toyota because of acceleration problems. Is there any way to find out about that? I am aware that this is probably just a problem I will have to deal with but I always try everything.

I was driving my 6-month old 2009 prius one summer day on a dry, paved, slightly downward incline when the following problem occurred. As I approached a traffic circle at about 5 MPH and then applied the brakes, my car jumped forward for about a second and a gold light on the dash was briefly visible through my peripheral vision. Because I was familiar with anti-lock braking systems, I think that I kept my foot on the brake pedal, though I may have reflexively released it in my startle. At any rate the car stopped a few feet later. Thankfully there was no collision, largely due, I believe, to my habit of coasting to a stop when practical. However, this was a bit unnerving, and also since it was during the period of concern about toyota prius' unintended acceleration, I made a point of reporting it to my car dealer. I could not identify which dash light had flashed for a second. The dealer's response was that there was probably an uneven surface on the road that caused the problem. Sure enough, there had been both a shallow pothole and a bit of gravel where the stopping problem occurred. However, I take issue with toyota's blaming road conditions for this problem when clearly the problem is that the car cannot respond appropriately even during very slow speeds. The problem hasn't recurred because I avoided the pothole afterward and never have to stop on a dime, pothole or no. I have had cars with anti-lock braking systems (ABS) and never encountered this problem with them. Therefore, imo toyota needs to improve the ABS or the (then new) stability control feature on priuses, both of which my car has. In all of the hype about toyota cars' sustained unintended acceleration, I do not remember that this other event that I have described was also being addressed. How come? Where are the federal safety agency, nasa, and toyota on this?

I have a 2009 prius base with 42k miles. After placing the vehicle in park and waiting in the vehicle, it suddenly lurched forward about 1 or 2 inches and with enough force to shatter a light post. This seems a dangerous flaw. It happens frequently; after speaking with a repair shop, I was told this is normal for a prius and is part of the recharging design of the hybrid system. I was advised to use the parking brake whenever possible. This seems dangerous.

Event: incomplete brake feel, during slow and steady application of brakes on slick or rough road surfaces, when the anti-lock brake system (ABS) is activated in an effort to maintain tire traction. The system engages and disengages rapidly (many times per second) as the control system senses and reacts to the tire slippage. If the same brake force is applied under these conditions, in the worst case, this may lead to an increase of vehicle stopping distance and thus raise the possibility of a crash. Toyota says that the older priuses, like mine, use a different ABS system, and so are not subject to recall. But it seems like a similar issue. Failure: whenever there is a slick, wet road. Correction: I checked with the dealer, all systems were checked safe, tires' psi were adjusted, it was felt that there was some tire noise. Incident continues intermittently.

When at a complete stop at a stop light our 2009 prius tried to accelerate on its own and my husband had to stand on the brakes to keep it from moving forward. Toyota was able to get info off their black box showing both the accelerator and brakes were applied at the same time. We keep hoping they are researching this problem but their call this week (after reporting this about 90 days ago and 2 black box downloads at the dealership) says it was driver error since they couldn't duplicate it and their engineers say it is within normal operating range. Toyota rep "l" says toyota is not releasing how many unintentional acceleration issues they have had since it is proprietary information and that they will not discuss other trends or cases they are not looking for trends between reports only downloading each individual car's info not looking at what is written in the complaint. She says toyota and your government can't find anything which means it must be safe. Safe? We have not let our kids ride in this car for over 6 months as we hoped a solution would come up from toyota but now we just really need info to know what is really going on with these vehicles and how many accidents there really are. The toyota rep on the phone says they have never duplicated a customer concern and that ours is unusual because people usually report right away and after an accident. I had asked how busy they are since it took so loooong to respond and she stated she takes about 2-5 calls a day, but previously had been taking 10-15 per day and there are about 40 people in her position. How many issues are there and is this a big deal about nothing or a big coverup? We just want to make a good decision for our family please help!

I was involved in 2 identical accidents over the past 6 months with the same car, a 2009 toyota prius. In december '09 I was making a right turn to pull into a parking spot. I was completely in the spot and went to come to a full stop when my 2009 toyota prius suddenly accelerated and crashed into a car. Then again on june 21, 2010, I was making a right turn into a parking spot and the same car suddenly accelerated as I went to come to a full stop in the parking spot. This time the car jumped the curb and went through a chain link fence. Both times I was making a right turn into the spot, both times I was braking and both times the car accelerated as I went to come to a full stop. The dec '09 accident was reported to the police, the june'10 accident was not.

I was driving my newly purchased 2009 toyota prius (VIN# [xxx]) on rt 66 in arlington virginia on march 31, 2010. I was driving approximately 50-60 miles per hour and accelerating. I took my foot off the accelerator to slow the car and the car kept accelerating. I then depressed the brake, but the car did not slow, and in fact I heard what sounded like the engine 'gunning' and it continued to accelerate. I pressed the brake down as far as it would go and while the car slowed its acceleration, it did not slow or stop the car. As soon as I lifted my foot from the brake, the car began to accelerate again and I could hear the engine racing. I pressed the brake again, and the same thing happened ' the car slowed its acceleration, but did not slow its overall speed. As soon as I lifted my foot from the brake, the car accelerated. I did this three times, becoming increasingly afraid. I then jammed my foot hard on the brake and pulled off onto the side of the highway. I turned the car off, and it finally stopped. I sat there for a few moments, then turned the car back on and got back onto the highway. As soon as I got up to highway speeds, the same thing happened again ' the car accelerated on its own and the brake would not stop the car. I pulled over a second time and turned the car off as the only was I could find to stop it. I turned the car on again, and this time was able to reach my destination with no more incidents. I reported the problem to the carmax dealer from whom it was purchased and have been on hold to report this directly to toyota for over 30 minutes, but have been unable to get through. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

We purchased a 2009 prius, 11/08. In 3/16/09 it accelerated unexpectedly on the nj turnpike near newark airport, a speed judged at 85 miles/hour. I was the driver, there were 4 passengers. Clearly unattended acceleration not caused by a floor mat. Scenario: traveling in right lane, came up behind cement mixer traveling at 45-50 mi/hour; accelerated quickly to get into middle lane; middle lane traffic constant, traveling min. 70 mi/hour; once in middle lane, de-accelerated; instead of de-accelerating, the car engine roared, taking off at an unbelievable speed; turned on flashers, put foot on brake; able to control speed of car, breaking all the time, engine roaring. No place to pull over. Only thought: get to toll booth, hope I could stop it completely with brake; suddenly, after about 5 min., there was a sound in the engine (?) like a thud; car resumed normal operations. Follow-up: went into nyc, drove car home that evening, 3 hour drive; husband took car to vineland toyota dealer where bought; they said black box showed that, in addition to most recent acceleration, there were prior accelerations; we never noticed them; they could find nothing wrong with it; said mat had been the problem; husband, former ceo/amer. Lung assoc., contacted toyota regional, saying that he was not satisfied with diagnosis of problem - we were afraid to drive the car. Knew management because of toyota's support of ala. In fact, after his retirement, endorsed '02 prius in toyota brochure, and was featured in 2 toyota videos; management sent techs from reg. Office; reps concurred with dealer: problem was floor mat. Outcome: no work we know of was done to rectify acceleration; mat removed, but couldn't see how it interfered with pedal. Couldn't replicate the event by moving mat around. No explanation for thud; little likelihood that the mat could slip back in place. Don't trust car! Please advise us of your intent on this matter. Thank you.

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!

Previous to the accident at the 5,000 mile check up I had reported to the toyota dealer that the car would sometimes jump forward when the engine transitioned from electric to gas mode. They assured me that this was normal. On february 4th at 1035 I was stopped at an intersection behind a large van. The car was in the electric mode when the gas mode kicked in and the engine raced up and the car lunged forward striking the van in front of me. There was no damage the van, the front of my car was damaged. I called the police. The van driver had a disabled passenger and left as there was no damage to his vehicle. The police arrived and I explained that my car had for some reason lunged forward striking the other vehicle. Since no one was injured he wasn't required to take a statement from me the next day february 5th I took my car to the toyota dealership for my 10,000 mile check up and again explained about the car lunging forward during the transition from electric to gas mode. No action taken other than assuring me that this normal. On march 4th while sitting at another intersection the car again lunged forward for about 6 feet before the full depression of the brake caused the engine RPM to come down and the car to stop. At this time I called and spoke to the general manager of the toyota dealership and he said to bring the vehicle out to the dealership and they would run a full set of tests. On march 10 I returned the vehicle to the toyota dealership and they kept the vehicle overnight and returned to me the next day march 11, 2010. According to the maintenance chief there was nothing in the tests that indicated any problems. Unsatisfactory answers each time I have complained about the problem, now my car is damaged and toyota says everything is fine, I think not.

While in 'cruise control' with no use of the gas pedal, the car started to increase speed beyond the set speed. When I realized what was happening, I stepped on the brake which overrode speed control and began slowing down as it normally would if the car was not accelerating but at steady speed, note: date below is approximate. Event happened twice during summer of 2009 at high speed (setting at 70mph).
