Tl*the contact owns a 2010 toyota prius. While driving 20 MPH over rough terrain the contact applied the brakes and they failed to engage. The vehicle was not repaired nor was there a diagnostic test performed. There were no prior warnings. The current and failure mileages were 6000.
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 been experience momentary loss of braking power while driving my 2010 prius on rough road surface or potholes more than 30 times since I own this vehicle. I filed a complaint (odi #10304434) back in feb 3rd. 2010 before the recall from toyota. My prius was included in the recall, so I brought the vehicle back to toyota service center for the recall. Toyota updated the ABS ecu software on my prius on feb. 2010. Since toyota updated the software for the recall, I still experience the same problem multiple times, and it is not only happen during slow and steady application of brakes, also happen when I use the brake in more sudden fashion even at moderate speed (30-40mph). I brought my prius back to the toyota service center again in may 2010 to recheck the ABS ecu software, and they said the software is the latest updated version, and my braking system is meeting the manufacture specification. However, this problem is still exist as of today, and my concern regarding safety of this vehicle is growing because this problem lead to increase vehicle stopping distance and thus raise the likelihood of a crash or accident.
Tl* the contact's brother owned a 2010 toyota prius. The contact stated her brother died in a head on crash. While he was driving at approximately 65mph north bound, a truck waiting at a traffic light was rear ended by another truck pushing the truck into the contact's brother lane of traffic. The contact stated witnesses advised her that brakes failed on her brother's vehicle and he was not able to bring the vehicle to stop when he saw the truck approaching. The police report was not available. The VIN was unknown. The failure and the current mileage was 21,000.
Toyota prius accelerates suddenly when driven over bumps, such as speed bumps or other bumps in the road, usually when going under 30mph, and often with the brakes being lightly pressed.
Tl*the contact owns a 2010 toyota prius. The contact stated that whenever she drove over a pot hole or railroad tracks the braking system did not function properly. The vehicle was taken to an authorized dealer who stated that the failure was due to a design flaw. The vehicle was not repaired. Updated 10/28/10.*lj updated 10/28/10
Toyota prius braking problem; I had the "recall" fix applied; I have noticed in the last two weeks that the car has started to have brake failure again when going over bumpy surfaces. It had been fine for a while, but this started happening again. I have contacted dealership regarding the same.
Brakes do not work when decelerating and road is uneven or bumpy. We took the car in for the recall fix and the problem persists. Brake failure happens 3-4 times/ week driving in seattle.
When attempting to stop our 2010 toyota prius, the car lurched forward, and continued to move. I let off the brake pedal, and reapplied the brakes, but they did nothing for about 30 seconds - at which point the car stopped. After contacting both our toyota dealership, and the toyota customer service department, they will not look at the car until next week.
Grabbing brakes: parked and sat in the car on a slight inclined driveway for some time listing radio. When I started backing up and tried to brake, there was no braking and then clunk clunk noise and car stops, tried again, same thing no braking and then little more pressure on brakes, clunk clunk noise cars stops. There was no way to smoothly glide the car down. This happened around 5 times. During last service I explained dealer about the problem but they could not reproduce it.
While braking and the car is slowing down to below about 10 miles an hour, it will surge ahead if it goes over rough pavement or a bump. The ABS recall has been performed on the car, and it was brought back into the dealer after the recall and the dealer confirmed that the recall was applied. The dealer claims that this behavior is "normal". The car has been back to the dealer two times so far.
Like all other 2010 prius complaints, when I apply the brakes and go over a bumpy surface, the brakes release causing the car to jolt forward. I took my 2010 toyota prius in to the dealer due to the recall. The service manager stated my car would be fixed in less than thirty minutes. Whatever they were supposed to do to fix the brake problem did not happen or did not work. My car still jolts forward when I am pressing on the brakes and I hit a bumpy surface. I am scared for my own safety. In addition, I cannot help but wonder what this problem does to my tires. I have had the car since july 2009 and have gotten two flat tires in the past 11 months! I have put so much time and money in to this car, and I haven't even had it for a full year.
Tl* the contact owns a 2010 toyota prius. The contact stated when driving over a pot hole or any uneven road surface, the vehicle would exhibit a delay in braking. The brakes would hesitate to engage when depressed. The dealer advised the vehicle was under the federal safety agency recall campaign id number 10v039000 (service brakes, air; antilock: control unit/module) and received the recall repairs. The failure persisted after repairs. In addition, the brakes would sporadically become stuck when braking in reverse and the then would begin to jerk violently. The vehicle was not further repaired. The failure mileage was 9,000 and the current mileage was 11,786.
Tl* the contact owns a 2010 toyota prius. The contact stated when driving downhill and attempting to brake, the brakes would not engage and intermittently could not be depressed. The contact had received repairs under the federal safety agency recall campaign id number: 10v039000 (service brakes, air: antilock: control unit/module). The dealer was unable to duplicate the failure and no further repairs were made to the vehicle. The manufacturer was contacted via email and the contact was awaiting a response. The failure persisted. The failure mileage was 5,000 and the current mileage was 9,000. Updated 07/06/10.*jb updated 11/15/10 *cn the consumer stated there is still a delayed response in the braking mechanism when going down hills. Updated 11/24/10
We purchased a 2010 prius in may 2010. My wife drove the car out of a shopping mall driveway into the left hand turn of the road and pulled up behind a truck. She was traveling about 5-10 MPH on a normal road, no pot holes or wet conditions. She had her foot rammed to the floor but no brakes! She went into the back of the truck, causing extensive damage to the front of the car and windscreen. She had two children in the back with her. Seems like they have not fixed the problem! We were told by dealership that there were no problems and that every car on the lot had been fixed! Not repaired yet. Not sure I want it back.
I own a 2010 toyota prius, and last week I had the ABS ecu updated per the recall. Prior to the update, braking over a bump or pothole would result in a little 'skip' on the road as the brakes kind of fluttered. I just pressed the pedal a little harder and all was well. Post update, I have a serious safety problem. I have experienced the brakes disengaging completely as the car hits a bump. The little 'skip' is gone, and now there's a panic moment where the car lurches forward with no brake pressure. I have to really mash the pedal the get the brakes back. Prior to the update I was a little worried that the slight increase in braking distance might have resulted in a crash. Now, I am very afraid. The car is almost uncontrollable when this happens, and it is always unexpected. I feel that if I crash, I will be held liable for something that isn't my fault. I ask the federal safety agency to revisit the toyota recall for the 2010 prius and make them prove they fixed the problem. I do not think they will be able to.
I have a 2010 prius that has had the brake recall fix applied. But when I am turning right applying the brake and then hit bump/chuck hole the brakes fade for just a few seconds. No accidents but does not give driver any confidence.
Severe brake grab in slow speed reverse or forward. Very intermittent. Research shows same complaint found in numerous complaints on the federal safety agency site. Dealer and toyota unaware and were of no help in resolution.
I own a 2010 toyota prius. I was having braking issues before the safety recall. It would accelerate when I hit a bump while braking. I told brought my vehicle in for the first day of the recall and it was "fixed." now the problem is back. My car suddenly accelerates when I'm slowing down/braking and hit a bump.
Tl* the contact owns a 2010 toyota prius. The vehicle was previously repaired under the federal safety agency campaign id number: 10v039000 (service brakes, air:antilock:control unit/module). After retrieving the vehicle form the authorized dealer, the vehicle would exhibit an increased stopping distance when braking from lower speeds. The failure began to recur intermittently. The failure mileage was 3,000 and the current mileage was 14,000.
2010 prius - this car was recalled for a braking problem. The "software fix" was completed on my car, but the same braking problem still exists in the car. A follow-up visit to the dealer complaining of the problem still happening resulted in nothing being done to fix the braking problem. The problem : occasionally when braking over a bump the brakes disengage for a brief time (probably less than a second) and result in an increased stopping distance and possible accident. In other words the recall fix has done nothing to correct the problem - - if it was bad enough to have a recall - and it doesn't get fixed - then it must still be a significant problem.... This problem occurs often - but not easily demonstrated. It has happened since the car was new and we now have 11,000 miles and it still happens.
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.
Tl* the contact owns a 2010 toyota prius. The contact stated when braking from speeds of at least 30 MPH, the vehicle would abnormally surge forward. The dealer was unable to duplicate the failure. The contact stated the failure had occurred since the date of purchase and continued to recur intermittently. The vehicle was not repaired. The failure mileage was 300 and the current mileage was 9,650.
I was driving the car on a road approx. 25 MPH. I hit a dip in the road right as I was braking to make a left turn. The automobile surged forward despite my foot being on the brake. This has happened repeatedly since having the recall fix!!! This problem must be fixed. We have repeatedly contacted toyota about the problem and get the same answer every time - there is no problem. I do not consider it to be normal for the car to surge forward while my food is firmly on the brake. What does it take to get something done! We tried arbitration to get rid of our vehicle and toyota basically said that we were lying about the problem. Please review and recall. I know by reading the other complaints that I am not the only one having this issue. This is a safety hazard!!!
Our new 2010 toyota prius lost its brakes for a short period when driving down a steep hill at slow speed (10 MPH). Although I was pressing on the brake pedal the brakes completely released for roughly 2 seconds and then re-applied. We had just driven over a small but sharp bump. I understand how ABS works, and this was not ABS. The brakes completely released and the car "jumped" forward - it jumped because the hill was quite steep. What is most disturbing is that the car had just been serviced (may 29th) and the event happened may 31. When I called the dealership they said the car had been recalled for a brake problem but they had "forgotten" to do the recall. Further, I have owned the car for five months and have not received a recall notice from toyota.
2010 prius accelerates while braking and surges in acceleration from a stop while accelerating slowly. Many but not all occasions were while going over bumps and/or wet road. This has happened several times since owning the car. Toyota cannot duplicate the problem in the testing and denies that it is real. It has been brought into toyota for repairs but the problem persists. The car is now parked and we will not drive it as it is not safe. We filed a lemon law claim (ca) and toyota has denied the claim with a form type letter.
My 2010 toyota prius continues to experience the momentary loss of braking power even after the recall fix was applied back in march. I experience the same loss of braking power as I did in the past when going over bumps, pot holes and the like, especially when hitting the brake on a decline. I brought my car back to the dealership and a field tech specialist was unable to reproduce the problem - but I have experienced it a half dozen times since the recall and have notified toyota's hq - they have not responded. I continue to feel as if pedestrian, other driver, and my own safety are at risk with this continued brake issue that toyota cannot seem to fix.
All brake rotors had a crack perpendicular to the rotation.
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.
