While driving my 2010 toyota prius on roads with lots of bumps, potholes, sewer covers, etc, I have braking problems. When driving over one of these "obstacles" and I touch the brakes, the car lurches forward as if accelerating or slipping. I can then release the brake and step on it again to slow/stop the car, but if there was a car close in front, I would have certainly hit it. I purchased the car in august 2009 and have had this same problem happen at least 6-10 times.
My 2010 prius has been exhibiting momentary loss of braking when passing over a rough surface. My neighborhood has several roads with steep slopes and although my speed on these routes is almost always under 20 MPH, on several occasions I have noticed an uneasy feeling of loss of control on passing over potholes or seams in the pavement when going downhill. I had written this off to unfamiliarity with a new vehicle, since I only purchased the car on 12/31/09 but when I read today's ny times article, the symptoms it described were exactly what I had been experiencing. I have not yet contacted the dealership but plan to do so right away.
Dear, the federal safety agency I was driving my prius in november of 2010 and noticed that the braking system was not braking well. I recently was involved on jan 29, 2010 in an incident driving out of the parking lot from work were the brakes failed on the vehicle when I went to stop the vehicle and the car skidded and struck some ice/snow (one the edge of the parking lot) causing damage to my front passenger side bumper. I am not as concerned about the damage as I am about my overall safety in the vehicle. I have reported the problem to toyota and they have responded and I have told them that there is an issue with the braking. I want to take this time to formalize my complaint. I am not checking crash and property damage due to the fact that it is not well defined on this page although I had property damage to the car itself and I crashed into snow/ice on the side of the road.
Occasionally when braking at a relatively slow speed on a bumpy or slippery surface the brakes feel like they stop working. My immediate response is to press the brakes harder and that seems to resolve the issue. I don't remember any sense that the ABS system kicked in during these situations. I have never not pressed harder on the brake pedal so don't know whether the loss of braking sensation would continue if no more pressure was applied to the brakes. I have also felt this sensation when braking while cornering at slower speeds. I don't know if a slippery or bumpy surface is always involved when I experience the loss of braking while turning, but at least on one occasion during cornering there has been a bump going from a slightly raised asphalt surface to lower concrete surface attached to the curb for the passenger side wheel only.
Tl* the contact owns a 2010 toyota prius. While the contact was driving 30mph traveling over a rough terrain he attempted to brake and noticed that the vehicle suddenly surged forward before the brakes would activate. The vehicle has not been diagnosed by the dealership and there were no prior warnings. The current and failure mileages were 1500.
Driving 35mph on straight road and ran over some unseen potholes. Applied brakes and they did not function as expected. Much less braking power than normal.
2010 prius brake surge when hitting bump in road when brake is engage.
I have had the following occur several times since I purchased the vehicle in july 2009: when braking on snow or ice or braking when passing over a bump or pothole the brakes will feel as if they are slipping and the car will accelerate for a fraction of a second. It's as if the ABS is releasing the brakes too long before reengaging them, resulting in the car to stop decelerating momentarily.
2010 toyota prius seems to accelerate when I apply brakes to slow down and car goes into shallow pothole. This event is repeatable and happens every time I slow down at a particular stop sign with a pothole in front of it. Fortunately there has never been a car in front of me and I now know to avoid this spot. Car behaves normally once it has cleared the pothole. This occurs at slow speeds ( 20mph down to 0 ) has not happened anywhere else, but happens everytime at this location.
The brakes seem to release if they are being applied while driving over a rough surface - speed bump, potholes, etc. This has occurred about 10-15 times since buying the vehicle in august 2009.
When braking, my toyota prius unexpectedly jolts forward if I hit a bump in the road. This happens consistently nearly every day I drive it.
I purchased a new toyota prius 2010 in december 2009. Almost immediately I noticed braking was 'odd' and I felt like when I would brake sometimes, the car jolted forward before stopping. After some self monitoring, I realized this particularly happened when crossing railroad tracks near my home en route to work. I have not had an accident but instead, have tried to brake more slowly and in general this has helped. However, a few times in traffic I have had to stop abruptly and about half the time it does the same thing, causing me to fully slam on the brakes. In the past I have had several toyota cars and rarely needed the full force of my anti-lock brakes in such situations. I have reported this problem to the dealer and he requested I wait until the 'break-in' period was over before making any decisions. That break-in period was defined as 5000 miles and I am now at about 4800, and the problem has not changed. When I reported it to the dealer, I had about 3000 miles on the car, and it was about one month after purchase (early january). At the time, the brakes were checked and no problem was identified. Today I contacted the dealer about turning the vehicle back in since I am concerned and not happy with the vehicle's performance.
My 2010 prius iv purchased in june, 2010 has on several occasions when I brake at slow speeds and I cross over a bump in the road the car momentary surges forward.
I purchased a 2010 toyota prius v in november 2009. Shortly afterwards my wife experienced the problem with the brakes. She went to apply the brakes but the car just would not slow down. She practically had to stand to apply enough pressure to bring the car to a stop. We went back to the dealer twice, but could not find anything wrong.
Vehicle surges forward when braking over road surface that is not smooth. Symptom makes safely judging stopping distance very difficult, and in our opinion, increases likelihood of an accident. Toyota dealer claimed they could not replicate issue and that vehicle's computer did not report/record any problems. We can replicate issue over same bump everyday.
2010 toyota prius iii, purchased december 2009 from dch brunswick toyota, north brunswick, nj 08902 I experienced atleast 3 different incidents of the following, sometimes at the same spot on a road - when braking, if a pothole or bump in the road is hit, the car seemingly jerks forward/accelerates for a split second.
The car has hyper-sensitive brakes whenever I am backing up from a parked spot (e.g. Backing up from a parking space at a store.) when backing out of a space (using just idle speed and tapping lightly on the brakes to control the speed) tapping lightly results in the car brakes forcefully engaging and slamming the car to a stop. This happens only after the car has been warmed up; parked (like going to the store to shop) and then you re-enter it to leave. The hyper sensitive breaks continue for a short period of time while I am positioning the car to get out of a parking space and onto the road. After the first occurrence of the forceful braking, putting the car in park, pumping on the brakes several times usually corrects the problem. Since it happens randomly, you never know when it will occur. Toyota says there is nothing wrong with the brakes when I brought it to their attention. They said it is common with priuses. This is not true. I own a 2007 prius and never had this problem. This problem has been mentioned several times by other 2010 prius owners on the priuschat.com website.
When I drive over a bumpy road and apply the brakes, my car does not stop.
Driving a 2010 prius with a half inch of fresh snow on a residential street at 20 degrees. Driving at 12 MPH, slowing to a stop at a stop sign. Twice the brakes stopped working, causing me to come to a stop beyond the pedestrian crosswalk. Fortunately, no pedestrians were there. It felt as if ABS had engaged, causing me to lose control of braking. Even if this is a design element, it caused me to not be able to stop in time. I was going 7 MPH when this happened and would have easily stopped the car in time if this had not happened. After this incident I had to approach intersections at 3-5 MPH, afraid that my slow speed would cause somebody behind me to rear end me.
From the first days with this vehicle we have had an intermittent issue with the brakes. So far, this issue only occurs at very slow speeds, such as when backing out of the garage or when backing out of parking spaces. On occasion, we have experienced this problem in the forward direction when stopping in the slow conditions of a parking lot. Following is a description of the braking action: 1. I start the car (power button with foot on the brake). 2. I place the shift lever in reverse or drive with foot on the brake. 3. I release the brake pedal. 4. The car eases backward (or forward, as the case may be). 5. I apply the brake , either to shift into drive or to check for traffic before continuing. 6. Several times per week the brakes lock the instant my foot touches the brake pedal. 7. When this problem occurs, the locking action will repeat each time I release the brake, ease backward or forward, and brake again. 8. The brake locking is so instantaneous that passengers' heads jerk and they look surprised. 9. The braking action is more like that of flipping an electrical switch than of pressing a brake pedal. 10. From the beginning, I have tried to determine if a certain sequence of actions triggers the locking. I cannot come up with anything. So far, the only constant is that this locking happens with the first stops after starting the car. I have not experienced it with subsequent stops. However, heaven help us if this were to occur at higher speeds! At the 5000 mile service, I asked about this issue. The service rep said that some prius owners had mentioned that their brakes "grabbed" once in a while. The rep said that it could be a "wet brake" issue.
Tl* the contact owns a 2010 toyota prius. The contact stated her vehicle surges when she goes over a pothole and hit her brakes. This has been happening since she purchase her vehicle. The vehicle was taken to the dealer and the technician test drove the vehicle with her but the failure did not occur again. The failure mileage was 4,000.
I bought toyota prius 2010 in early december 2009 and have experienced at least five times brake problem. I basically can't make my car stop effectively when I hit the brake. It is worse when you drive fast or in a snowy or icy days. Now I have to slow down way before the stop sign so I can avoid the brake problem, and I wouldn't let anyone else to drive the car for the fear of car accident.
I have had my 2010 toyota prius iv since august 2009. Over the past two to three months, I notice that sometimes when I brake, my car jumps forward a little bit before braking. It feels like skidding on ice but there is no ice around. It happens at least a few times every week. I have been lucky so far that this issue hasn't caused an accident. I now make sure I have extra space when braking because I can't seem to find a reason for this happening. There is no way to predict when the brakes will react that way. I am planning on contacting my dealership today.
Tl* the contact has a 2010 toyota prius. The contact stated that the vehicle feels as if the brakes release if he hits a bump while pressing the brakes. The contact stated that it felt like the vehicle surged forward.the contact stated that it only happens when the vehicle hits a bump or pothole. The failure mileage was 100. The current mileage was 5000.
I bought my new 2010 prius june 6th 2009. Since about oct 2009, I have noticed when I am braking and go over a pothole in the road, the car seems to speed up. There is a pothole by my house so I can test this frequently. It happens when I go about 30 mps (as I'm slowing down due to the stop light on the corner). I took my 2010 prius into the dealership on dec 28th and they were very unhelpful and rude. They told me to remove my floor mats even though what my issue was had nothing to do with floor mats or the gas pedal. What can I do to help encourage them to fix this issue as I find it unsafe to drive my car?? I have almost rear ended the car in front of me twice. It's very concerning.
Prius 2010. Intermittently lose braking ability. Especially when road is wet and uneven. When coming to a stop light and traveling relatively slowly, if the vehicle goes over uneven pavement (pothole or just "rubbly"), it's as if the ABS gets confused and very temporarily gives up. This is in city driving. Starting from under 20 MPH. Trying to stop at a light and with cars in front of me. I have driven the exact same route in other cars and not had the same problem. (prior vehicle was bmw 528i (model year 2000). This is a route I drive daily (between dropping my daughter at school and going to work.) I have observed the problem multiple times.
Regenerative braking disengages for a second or two before mechanical braking takes over causing car to lurch forward/accelerate when braking on uneven road surfaces. This effect was noticed twice at speeds less than 15 MPH when front tires hit ruts in road attempting to brake at stop lights or when going around a corner. I try to drive close to the right curb on the even road surface to avoid breaking when pot holes/ruts are present in my lane where other cars typically drive.
My 2010 prius brakes briefly stop working when I'm braking while driving over a bump or pothole. I have not been in an accident however this can lead to an accident in the future. This happens periodically and can be recreated.
I bought a 2010 toyota prius ii november 2009. Within 1 month period, I had experience two separate brake problem. Once was passing a railway track and the other time was making a right turn. Both times I stepped the brake to reduce speed and failed. That means the brake did not reduce the speed of the vehicle. Fortunately, no car was in front me and no accident happened. I then reported to my dealer and sent my car back to check. The dealer told me they failed to replicate the situation and everything was normal. Nothing was done. They then talked to toyota customer service line and toyota said it is normal to feel the brake did not engage when crossing a bump. I was really disappointed.
