The vehicle was taken to the dealer for inspection but they could not determine the cause of failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 10,000.

When going over bumps in the road or potholes, it seems like the car loses control. It seems like it slides out or jerks forward. It catches itself after a couple seconds but is scary.

The contact owns a 2010 Toyota Prius. The contact stated that while driving approximately 10 mph, the contact abruptly applied the brakes in an attempt to avoid crashing into a vehicle ahead of her yet the brakes did not respond. Instead, the vehicle abnormally accelerated and the contact crashed into the preceding vehicle. The vehicle was taken to the dealer whom performed a diagnosed that was unable to locate a failure code. The failure mileage was 5,800 and the current mileage was 58,030.

The contact owns a 2010 Toyota Prius. While stopped at a traffic light, the vehicle was hit from the rear by another vehicle. After the vehicle was hit, it accelerated to a high speed. The contact engaged the brakes but the vehicle continued to accelerate; the contact attempted to turn off the ignition but that did not stop the vehicle. The vehicle changed directions and crossed over a grassy area and crossed over three lanes of traffic and crashed into a concrete median. The contact stated that all the lights failed. The two passengers were injured. A police report was filed. The vehicle was destroyed. The VIN was unavailable. The current and failure mileages were unknown.

My wife was driving our new 2010 Prius home on 16 Nov 2010. As she was turning the car into our driveway at approx 5:30 pm the vehicle lunched forward at great speed on its own. We have a long driveway, it took her about 30 to 40 feet the get the vehicle stopped. While pressing on the brakes the drive tires kept spinning and left rubber marks in the driveway. Bought the vehicle from rick hendrick Toyota in sept 2010 in fayetteville, nc.

Tl- the contact owns a 2010 Toyota Prius. While stopped, the contact depressed the power off button to shut the engine off while the vehicle was still in drive. The contact stated the vehicle was designed to automatically go into park when the power off button was pushed. The contact exited the vehicle and the vehicle rolled away, crashing into a pedestrian. The pedestrian was transported to the hospital and sustained a broken tibia and crushed right ankle bone. The manufacturer was not made aware of the failure. The VIN was not available. The vehicle was not repaired. The approximate failure mileage was 15,000. Kmj.

Vehicle surges when brakes are applied while traveling over railroad tracks or rough pavement. Surge lasts for 1 to 2 seconds until braking resumes. Vehicle behavior can be easily replicated.

The contact owns a 2010 Toyota Prius. While driving at less than 5 mph, the contact was coming to a stop to park her vehicle when the vehicle accelerated on its own. The brakes were applied where they did not engage. The vehicle crashed into a brick wall and there were front end damages and no injuries. The vehicle was towed to a Toyota collision shop. There have been no diagnostic test to indicate why the vehicle accelerated on its own. The failure and current mileage was 6000.

The contact owns a 2010 Toyota Prius. The contact was braking from 2 mph when the vehicle independently accelerated. The contact applied the brakes and the brake pedal fell farther into the floorboard than normal. The vehicle went over a curb, sidewalk and over a grassy area before crashing into another vehicle. The front end of the vehicle was severely damaged. There were no injuries. The vehicle was towed to a an authorized dealer where the contact was awaiting a diagnosis of the failure. The vehicle was not repaired. The failure and current mileage was 13,000. Updated 11/23/10 updated 11/23/10.

Was driving Prius 2010 model ii with brake software applied by dealer about 1. 5 months ago. Today (7/27/2010) I exited highway and began gentle braking on offramp, as suggested by manual to maximize regeneration. About half-way down offramp, I realized car in front of me was completely stopped and that I had to stop much more quickly than I was planning to. I don't recall being particularly distracted, but I can't rule out I noticed the stopped vehicle later than I should have. In any event, I'm not sure how hard I pressed the brakes, but I recall distinctly thinking "OH, my god. Nothing is happening" and 1-2 secs later I plowed into the car in front of me. The collision was hard enough to cause temporary pain to the driver in front of me, but no air bags were deployed and the Prius appears to not have major frontal damage - hood is bent back and maybe slight frame distortion => the impact clearly was not at the ~40-50 mph I was going when just exiting the highway, so some braking clearly did occur -- but I have the distinct feeling that my previous car (Subaru outbook) would have easily stopped in time. After accident, I tested brakes by going 15-20 mph in parking lot and braking hard. Always stopped quickly, I'm guessing w/100% friction braking. So brakes are probably not "defective" in sense of lost hydraulic fluid, etc. . . But I have never before experienced the feeling "I'm not stopping" except once when losing traction on icy road with a non-hybrid. The fact had time to think this thought at all probably means maybe 0. 5-1. 5 sec passed while braking ineffective. Checked for tire/skid marks on road or evidence of strong tire wear and found none, while I have on other cars when I have had to brake hard => Prius not braking hard despite emergency. Seem to have been caught in transition between regen & friction mode? this is still discussed in Prius forums -- software fix not good enough!? this is potentially very dangerous. Btw,car was in "eco" mode.

I have a 2010 Toyota Prius that has the problem with the brakes sometimes dis-engaging when the car goes over uneven or slippery surfaces. Toyota was unable to fix this problem after I brought it in for the recall. The problem remains so I am stuck driving an unsafe car.

Today at yet another check for my 2010 Prius to try to discover the cause for the continual surging, I was informed that 160 times in the last 1 1/2 months I have driven with both the gas and brake pedals depressed simultaneously. This is a ridiculous assertion and completely false. Obviously there is an issue with the computer software in my Prius brakes. This is further evidence that there is a serious safety issue with the Prius brakes.

At about 7:45 am Sunday may 23, I was driving west on hamburg turnpike in wayne, gently accelerating to get better mileage, the light at berdan Ave and hamburg had just turned green, so I accelerated slowly to about 40 mph. At this point, I hear a shrieking beep and the car lurches forward as the brakes were applied. The dash lights up with the usual message square and the word brake! in the box. I look in all directions and saw nothing until I bounced over the construction plates. The box was gone, and the car resumed normal operation. I was puzzled. I thought it could be the plates. I checked with my son and he reminded me that in the model 5 we have radar crash avoidance. Upon further review I wanted more information. I took my son, and a camera, and drove the route again. Eureka! in all three attempts, the brakes were applied. I have pictures of the dash, and the plates. Did the car perform correctly? the second plate is not flush to the road and sticks out to the left. I think other drivers need to be aware of this possibility so they do not panic when it happens. The crash avoidance system could have been doing its job correctly. I contacted wayne police about the incident and the dispatcher said after consultation it is a county road, call the passaic county road department. My car computer will have recorded all 3 incidents. The third was not as big a jolt because the driver ahead of me had slowed considerably when he saw the plates. There is a warning sign that is beyond the plates in the picture. Let me know if anyone in service is interested in the information since this is a new feature and I know as a computer programmer of some 40+ years that a system does not always get tested for all possible events. I also cannot believe that unlike nyc where there must be no bumps or raised plates during construction that passaic county allows these plates to be installed without being flat or asphalted around the edge.

Toyota 2010 Prius, for 5 months it has been perfectly good. Bumps or uneven roads, no problem, got the Prius computer update 2-33 months ago. April 30 - driving on road with rough surface for repaving and with sewer covers sticking above surface, and no problem for 2 miles then hit a repatched hole and the car jerked ahead quickly but my braking slowed it down immediately. The entire process took 1 second. Luckily I had good reflexes. Scary but the brake worked well. Since that incident - 1 day, car is fine.

I made a NHTSA complaint on 1/27/10 for abs/unintended accel incidents in my Prius2010. Supposedly Toyota corrected the problem on 2/11/10. On 4/20/10 @ 12:50 pm, my Prius accelerated dangerously as I was coming to a complete stop on a slight incline. The car shot forward through a red light on a busy baltimore arterial. I was braking the car and trying to turn it to avoid hitting a concrete wall or cars in the opposite lanes. I turned very sharply,unable to brake the car; I feared it may rollover. My foot was on the brake the whole time. I hopped a curb on the median and clipped a traffic sign. I then parked the car and phoned the police. It was amazing no one got hurt or killed. Since this incident occurred after Toyota said they fixed the problem, I do not trust them or my car. I want a refund for this car, I will not drive it again:it is a death machine.

After taking my 2010 Prius in for the recall fix on April 1, 2010, the vehicle continued to exhibit safety defects. I reported this to the dealer who reported it to corporate and arranged for a field tech to analyze the vehicle on April 13th. They said we would hear from Toyota with in two weeks I never heard back from the dealer so I called the dealer last week. Dealer had not heard back. I filed under the lemon law. Then dealer informed me yesterday 5/17 that the car was healthy and there is nothing more they can do. My car experienced the same brake failure this morning, turning into a parking lot.

The contact owns a 2010 Toyota Prius. While driving approximately 30 mph and attempting to accelerate, the vehicle would not increase in speed. The contact continued to apply continuous, steady pressure to the accelerator until it finally began to accelerate. The contact stated the failure would occur sporadically, most often when accelerating from a complete stop. The dealer was unable to duplicate the failure and the vehicle was not repaired. The failure and current mileages were unavailable.

2010 Prius engine accelerates when braking over bumps/gravel. Brought car back to Toyota dealer for recall modification and problem still exists, in fact, seems worse.

I have a new 2010 Prius with less than 1k miles. On 4-9-10 while pulling into a parking spot I experienced a simultaneous loss of braking combined with unintended surge of acceleration. My Prius jumped the curb that was perpendicular to the parking slot and stopped as it slammed into a brick building about 8 feet beyond the curb. I utilized my safety connect button to record the time of the accident and had the vehicle towed to the dealer. I contacted Toyota customer experience center and now have a case #. I was told that someone would contact me within 2 business days. I am not at all comforted by this very scary incident. I would just like to have my 2005 Prius back as I never had any problems with it. I am seeing that my problem is not unique based on many similar problems on this NHTSA complaint site.

The contact owns a 2010 Toyota Prius. The contact stated as she was pulling into a parking space, the vehicle suddenly surged forward as she was making a relatively sharp left turn into the space. The contact stated she was probably going 3-5 mph when the vehicle accelerated. She slammed on the brakes and was able to stop the vehicle before it crashed into a parked vehicle. The consumer stated she had the recall performed on the vehicle in early March. The failure mileage was approximately 2,700. Updated 05/26/10 updated 10/05/jb.

2010 Prius with about 14,500 miles driving on smooth, wet, paved road 20 miles an hour on a curve. Neither foot was not on a pedal - car was coasting for several seconds as expected, slowly decelerating. In the middle of the curve, with both feet still not on either gas or brake, I felt and heard a notable surge of hard acceleration despite both feet being off the gas and brake. My wife in the passenger seat also noticed the surge. I immediately braked hard. The car slowed safely, and the unrequested acceleration seemed to stop as soon as I engaged the brake pedal. Nothing was touching the accelerator before the surge, during the surge, or when the surge ended as I braked - not a floor mat, not a stray object, not my foot. This is the first time we have experienced this exact pattern of symptoms. In the past, before the brake software recall was downloaded to our car, we had many episodes of temporary loss of braking power on bumpy roads. At least one of those prior episodes had unexplained acceleration accompany the temporary braking failure on a bumpy road. Today's incident was very different - I was not braking, and the road was not bumpy. Note that the 2010 Prius is not on the recall lists for the accelerator modifications, and that a sticky accelerator would not explain this behavior.

Although I took my vehicle in for the recall (2010 Prius) last week, the vehicle repeated the loss of brake/surge issue this morning. I also reported to my Toyota dealer last week about abnormal, sudden braking. When applying normal pressure to the brakes, on several occasions the brakes have locked violently, sending me and my passengers against our seat belts. Toyota claimed that the recall may make that better. It has not. Thirdly, I reported last week to Toyota that the car has on occasion shaken violently and made a loud clanking noise (like a washing machine off balance) upon start up, causing me to jump out f the car for fear of it blowing up. They said they had never heard of this. My CO-worker, a fellow 2010 Prius owner, reported the same issue.

2010 Prius still accelerates after "fix".

My make: Toyota model: Prius year: 2010 complaint number: 10311958 summary: my 2010 Prius completed its "recall" service yesterday. Today, the car lost power and died while I was driving on to the freeway. I was able to pull over to the side of the freeway and turned it on and off several times until it started. When I called the dealer which is located in thousand oaks, California, I was told by the consumer complaint person that the dealer would not fix the problem unless I was able to recreate the problem with a technician in the car.

My 2010 Prius was "repaired" last month. It intermittently accelerates without my prompting after hitting a bump. This acceleration is as intense as the car seems to allow, as if the pedal were to the floor or worse, and persists for at least one second and has not subsided since the abs actuator ecu was updated in the recall appointment. This acceleration is terrifying as it can't be anticipated as it does not happen every time I hit a bump, and can't be suppressed by the braking system. I have on several occasions been safely coasting to a stop with the brakes on and experienced this problem. In a few cases this acceleration almost caused me to hit the car in front of me at stop lights. I never did experience the symptoms described by Toyota relating to the delayed braking problem, but I fear this problem as much or more.

Toyota vehicles in all of the information I have read, Toyota nor the department of transportation has informed drivers to shift the vehicle to neutral when it accelerating by itself. By shifting the transmission to neutral it should allow the driver to bring the vehicle to a safe stop.

Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6). I left a message on your voice mail. I have a 2010 Prius. I called my dealership this am with concern about the incident last night with the gas pedal. The gentleman that spoke to me was very arrogant stating "I don't know what everyone is so worried about, all he had to do was put it in neutral". I asked him to stay on the phone with me while I did a test run in my car. I got in the car (with him on the phone) started driving and put my foot on the brake and pushed the joy stick to neutral, nothing happened, the car remained in drive. I proceeded to do this 13 times with the dealership on the phone, it only engaged in neutral 2 times out of the 13. I was getting upset and voicing my concern. I asked if I could bring it in and have it checked out. The dealership said to me "sure you can bring it in but I don't know what I can do about it". I was furious, I called the local channel 3 and they came out and did a story on it. We drove the car around and I put it in neutral probably at least 30-50 times and it did not engage 90% of the time. I tried calling Toyota headquarters and they are not taking any calls at this time, this was a quote and animated, you cannot talk to a real person. I don't want the car, I am afraid to drive it.

The contact owns a 2010 Toyota Prius. She confirmed she has experienced brake failure several times in the vehicle. While attempting a right turn over railroad tracks with her foot on the brake pedal, the vehicle abnormally lunged forward and began to accelerate. She continued to depress the brake pedal until the vehicle came to a stop. She also noticed that when driving uphill, the vehicle was hesitant to accelerate. The vehicle had not yet been taken to the dealer for inspection. The failure mileage was 65,000 and the current was 96,077.

The contact owns a 2010 Toyota Prius. The contact stated while attempting to park 10 mph with the brakes depressed, the vehicle abnormally accelerated. The contact was unable to stop the vehicle as it crashed into a store and struck a pedestrian. The pedestrian sustained injuries to the right knee, arm, and hip. A police report was filed and available. The vehicle was towed to a local body shop but was not repaired. The manufacturer was not yet contacted. The failure and current mileage was unavailable.

The contact owns a 2010 Toyota Prius. The contact was driving approximately 20 mph with the brake engaged when the vehicle accelerated. The contact crashed into the rear end of a Nissan. The weather was not a factor. The contact observed smoke coming from the vehicle. The rear suspension was damaged after the crash occurred. The insurance company authorized the vehicle to be towed to an impound lot. The VIN was not available. The approximate failure and current mileages were 36,000.

The contact owns a 2010 Toyota Prius. While driving approximately 20 mph and approaching a traffic light, he placed his foot on the brake pedal. The vehicle then abnormally accelerated as he traveled over a pot hole. Upon contacting the dealer, he was advised that he would have to wait until he received recall notification from the manufacturer before making any repairs to the vehicle. The VIN was not available. The approximate failure mileage was 4,000 and the current was 4,200.

I have owned 4 Toyota Prius hybrid vehicles (2005, 2007, 2008, 2010). I experienced a slight feeling of acceleration sometimes when depressing the gas pedal in the 07 and 08 models. I also felt a slight surge sometimes when braking. When I asked the Toyota mechanic about this I was told that stored energy from the hybrid system was being expelled. I never thought it might be a safety issue because of what he said. Now I drive the 2010 Prius, had the brake recall done last week and a couple days later, when driving over 3 slight bumps when entering a parking lot, I felt that same slight acceleration. Please continue demanding Toyota fix this dangerous problem. Please talk to the us congress about investigating these cars before there are more accidents. I think the 2010 Prius also has issues with acceleration as well as braking because I have experienced what I described in the 07, 08, 10 models.

The contact owns a 2010 Toyota Prius. The contact was driving approximately 35 mph, proceeding to make a turn. The brake pedal was depressed and the vehicle surged forward with a loud noise. The contact was able to slow the vehicle down. The contact will not drive the vehicle due to the potential safety hazard. The vehicle was taken to an authorized dealer. The vehicle was not repaired for the malfunction. The failure mileage was 6,000. The current mileage was 10,000.
