Bought a 2010 prius in october 2009. it currently has 3500 miles on it. at least three times the car felt as if it slipped on ice when applying the brakes (weather conditions were perfect - no ice, snow or rain). their is difficulty in clearing fog from the windows and one time i had trouble setting the cruise control. *tr
Toyota prius 2010: when the car hits a bump in the road it will accelerate so fast by itself which can be very dangerous and fatal. it can highly cause an accident if the driver cannot step on the brakes in time to stop the car acceleration. i went to my local toyota dealer here in queens new york and to my surprise the rep said" i have never heard of that complaint" and did not pursue the matter at all. another safety concern is that i hit a small pothole and the whole tire was damaged on my brand new 2010 prius which i have been driving for barely two months. i am very concerned about these safety problems and do not really know where to start getting assistance. thank you very much. *tr
I have owned a 2010 prius for about a month, and have driven just over 1000 miles on it. there have been three separate incidents now where my brakes have experienced a sudden failure while decelerating. each time occurred right after hitting a pothole or a bump in the road. passengers in my car have reported a feeling of the brakes "catching" or "jerking" while driving on bumpy roads. the three incidents i have mentioned were during winter and during possibly icy conditions. however, i know how to operate a vehicle on ice, and i am aware of how abs braking feels. during each incident, i would be braking slowly, with plenty of time, then hit a bump, and experience a feeling of skidding while the brakes disengaged for a few seconds. i almost hit a pedestrian at a toll booth, a concrete divider during highway driving, and another motorist at a sudden stop condition along another highway. please investigate these cars. i can compensate my driving skills to adjust for road conditions that i am aware of. if any sudden braking is required, and i hit a pothole at the right time, i will not be able to stop. *tr
2010 toyota prius. acceleration when applying brake in bumpy road. it happened when the speed is slow and there is uneven or drives over pot hole. *tr
I too have noticed a strange feeling of speeding up instead of slowing down when driving over a large bump on a street in my 2010 prius. *tr
My 2010 toyota prius suddenly surged forward for a few feet after going over a little bump in the road (like a manhole cover). this happened a couple of times. no injuries or accidents. i brought this to the attention of my dealer when i brought it in to change the oil @ 5000 miles. they said they could not replicate or detect the problem. i have not had any such incidents in the past 2 months. *tr
2010 toyota prius, purchased nov. 2009. using cruise control, the car accelerated quickly on it's own when i attempted to change speed by using the cruise control lever on the steering wheel. happened twice, then i stopped experimenting for reasons of safety. the problem is identical to the one described by steve wosniak in public two weeks ago--one that got a lot of press. acceleration stopped when brake pedal was tapped or cruise control was turned off. *tr
This problem has existed since the vehicle was purchased. cruise control either does not function at all or fails to function correctly. sometimes the cruise control will not engage. sometimes the cruise control will engage properly, but after applying the brakes (and disengaging the cruise control) the cruise control cannot be reengaged. two operations will cause the cruise control to begin functioning properly again: 1) turn the vehicle off; 2) put the shift lever into the neutral position, then back into drive. returned vehicle to dealer three times for repair. they did not fix the malfunction during any of the three repair visits. their final response was to claim that the vehicle was "functioning as designed". *tr
Tl*the contact owns a 2010 toyota prius. the contact stated that when slowing down and making a right turn, the vehicle accelerated; however, it has never occurred when he made a left turn. he was driving approximately 10 mph. the failure mileage was 4000 and the current mileage was 5000. updated 03/12/10. *lj updated 09/21/10
While driving my wife's 2010 toyota prius from colorado springs to alamosa we experienced the following anomaly. we were on the freeway (i-25) driving south on level terrain with the cruise control set at ~70mph. i noticed a significant increase in the engine rpm and could see the engine display for the engine in the pwr mode. i disengaged the cruise control and waited a short period of time and reengaged the cruise control. a short time later (~15 minutes) the rpm increase occurred again and i once again disengaged the cruise control. i did not use the cruise control again on the trip. my wife has used the cruise control rarely since her use does not include freeway driving. *tr
2010 toyota prius, i pick up the car at the dealer on 20 nov 2009. when ever i set the cruise control it works fine until i tap the brake to turn it off. the car speeds up. i have to press harder on the broke to get the cruise control to disengage and slow down. its as if the cruise control is not sensing that the brake was depressed and releasing. i took the car back to the dealer on 12-20-2009 having driven it a month and having a chance to get a feel for the car. they said nothing was wrong that all the cars did this. every car i have owned has had cruise control on it and has never acted this way. i also drive a rx350 lexus that does not have his problem. *tr
I have noticed issue with braking. i remember it had rained the previous night and the morning it was freezing. i was driving on rt. 76 to drop my son off to his work. on small stretch of rt. 76 has the 'cement patch' - those you typically see on a over pass. fearing icing, i hit the brake only to feel it not responding. in fact, i felt the car speeding up. the patch was just about 10-15 ft wide; the moment we were over it, i felt the brakes respond. *tr
On three occasions, my 2010 prius "leapt forward" when i drove over a man-hole cover. i have read the description of the braking issue on the 2010 prius and it sounds exactly like my experience. it only lasts for a fraction of a second, but it is quite frightening when it happens. *tr
I purchased a 2010 toyota prius in august, 2009. during the fall, 2009, i experienced two incidents, which in retrospect, i think involved sudden acceleration. on both occasions, i was driving home from work and went over a spot on the road which, because it was dark, i couldn't see for sure, but which felt like a pot hole. (i also think it may have been raining on both of these occasions, although i can't recall for sure). immediately after hitting what i think was a pot hole, i felt the car suddenly and dramatically accelerate. both times i applied the brakes and the car stopped accelerating. at the time, it did not occur to me what was going on. but, now thinking about it, i think it likely that the sudden jolt to the car, perhaps combined with moisture, caused some type of electrical malfunction, which thankfully, was short-lived (or at least stopped by braking). shortly after these incidents, i mentioned them to my wife. she reported that she had experienced very much the same thing on a separate (i.e., a third occasion) driving our prius. *cn
Tl*the contact owns a 2010 toyota prius. while driving 20 mph he applied the brake pedal; however, the vehicle did not slow down instead it accelerated at various speeds. the dealer was unable to duplicate the failure during a test drive. he stated that the failure occurred six times intermittently contact is concerned that if he continued to drive the vehicle the failure could cause a crash to occur. the failure mileage was 9,000 and the current mileage was 10,500.
I was driving my new 2010 prius (approx. 250 miles on odometer) when approaching a stop light earlier today with my foot gently applying pressure to the brake when suddenly the car surged forward accelerating. i am certain my foot was not on the accelerator pedal nor was anything on the floor and the floormat was appropriately positioned. the acceleration only lasted a second, ie once i applied more pressure sharply to the brake pedal the car slowed and the acceleration ceased. this is the only time this has occurred. *tr
I have been driving my 2010 prius for almost 6 months now and have experienced the car jerking forward and for a few seconds speeding up as if the brake doesn't work. this happens specifically if a pothole or bump in the road is hit and i'm braking. mostly when slowing down by hitting the brake. i actually noticed this almost immediately when i bough the car but since i've been reading up a lot about the 2010 prius not in the toyota recall list, i thought it is important to report it and get it fixed. one experienced the strangest feeling when this happens. almost as if the break pedal is hit and the car jerks forward as if the pedal is stuck and the car body moves forward. *tr
2010 prius acceleration surge - when i drive over a sewer cover or any similar indentations in the roadway the vehicle surges forward in an aggressive manner. i need to apply the brakes or steer to avoid any object in the path of the vehicle. it is very unsettling and dangerous since the surge is strong and unpredictable. *tr
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. *tr
2010 toyota prius- car tends to accelerate after hitting some potholes or bumps in the road when the brake is depressed. the first couple of times, i came very close to rear-ending the car in front of me because the bump or pothole was in the road at a traffic light and i was attempting to stop. i have been able to repeat incident but not all of the time (may depend on how hard the brake is depressed or how fast the car is going at the time). i noticed this shortly after purchasing and receiving the car on 24 oct. 2009. mentioned to toyota service staff at a new car orientation program, but was told that they had not heard of this issue... and perhaps the bumps in the road were causing me to not apply even pressure on the brake. i have adjusted my driving route as to not to go over the pothole which causes the most problems (or try to be vigilant about situations which may cause lurching) but was concerned when i saw an article reporting that other people are experiencing similar issues (http://www.freep.com/article/20100203/business01/100203028/1318/2010-prius-owners-complain-of-faulty-brakes-lurching-over-bumps). *tr
While driving with cruise control engaged and a situation occurs that requires braking; normal brake pedal pressure does nothing. i have to hit the brakes extra hard which significantly slows reaction time. this problem occurs randomly. when i took the car to the dealer i could not get the problem to repeat. *tr
2010 toyota prius accelerates slightly when brake is compressed and car is traveling over large road bumps or manhole covers/slippery surfaces (multiple times each time i drive). i have not yet reported this to toyota, based on the online and news-broadcast accounts of how toyota has responded to much more serious acceleration issues. i intend to attempt returning the vehicle to the company for a full refund. *tr
Tl* the contact owns a 2010 toyota prius. while driving 10 mph over railroad tracks, with her foot off of the accelerator pedal, she noticed that the vehicle suddenly began to accelerate without driver intent. she immediately depressed the brake pedal and the vehicle momentarily decreased in speed, however the vehicle soon began to accelerate again. she then put the vehicle in neutral and shut the engine off. she was able to stop the vehicle and within a few minutes, restarted the engine. the vehicle began to function normal. the vehicle was taken to the dealer where it was test driven. the dealer found nothing wrong with the vehicle and could not duplicate the failure. the contact stated that she had experienced the unintended acceleration over 12 times. there were no repairs made to the vehicle. the failure mileage was 4,000 and the current mileage was 8,352.
My 2010 prius (purchased 6/30/09) lurches forward when i hit a pothole or a sharp bump in the road while i have the brakes on. it has happened about 3 times since i've had the car. *tr
I own a 2010 toyota prius that i purchased in the fall of 2009. on several occasions i have depressed my brake pedal to either slow down or stop but , instead, the vehicle briefly accelerates and gives a feeling of "skipping" over the braking action. the vehicle then quickly corrects before stopping or slowing down. this has happened on more than one occasion on very specific types of terrain that i can describe as bumpy or uneven. i placed a call today with my toyota dealership in which i explained the above narrative to them. they responded with ignorance to the situation and stated that they will wait to hear from toyota on the matter. *tr
2010 toyota prius cruise control caused unintended acceleration when re-engaged. after disengaging cruise control set to 65 and coasting at 50 for a while when the cruise control was re-engaged the vehicle resumed in excess of 70 mph before i disabled cruise control. date of incident is approximate. i didn't think much of the failure at the time other than that the cruise control was behaving oddly (i have avoided cruise control on this car since). in light of the current investigation i thought i would submit a report. *tr
Tl*the contact owns a 2010 toyota prius. the contact stated that the vehicle suddenly accelerated and crashed into and through a garage; the air bags did not deploy. the contact sustained a bruised heart, broken sternum and two broken ribs. the vehicle was destroyed. the contact called the manufacturer who offered no assistance outside of taking a complaint. the failure mileage was approximately 3,400.
I purchased a brand new 2010 toyota prius v on september 24, 2009. it performed beautifully, and was a real pleasure to drive. however, a month or so later, with the car in reverse, i started backing out of a parking place and immediately noticed an unusually intense "revving" of the engine. startled, i immediately pressed on the foot brake, releasing it in little steps until the car was "inched" out of the parking place. i then shifted the lever into "drive" and proceeded on my way quite normally without any further problem whatsoever. in the ensuing months, this strange phenomenon has only repeated itself two more times out of hundreds of backouts from parking slots. there has been no other circumstance in which this severe " revving" has re-occurred. in the aforementioned three cases, i had no recollection whatsoever of pressing the foot throttle, and therefore have presumed that the problem is in the electronics or software, rather than in the floor throttle mechanics. in every other respect so far, my 2010 toyota prius v has performed perfectly. *tr
Tl* the contact owns a 2010 toyota prius. while driving 2 mph in reverse and removing his foot from the brake, the vehicle accelerated on its own. the failure has occurred approximately 3 to 4 times. the dealer was contacted and had not responded when the complaint was filed. the contact is concerned about the safety risk involved and doesn't feel safe driving the vehicle. no repairs were made to the vehicle. the failure mileage was 2000. the current mileage was 5400.
2010 toyota prius. going downhill and approaching a stop sign. my foot is steady on the brake and i am gradually coming to a stop. then, i inadvertently go over a bump in the road and the prius lunges forward. i had to immediately slam hard on the brakes in order to keep the car from going into the intersection. fortunately, there was no car or person in front of me as i was stopping. (i looked at prior complaints and this matches mine). *tr
While coming to a stop at a red light , i applied my brakes and at the same time , went over a small pot hole. it seemed to me like the car sped up. it only happened for a split second but that second could mean the difference between hitting someone and missing. this has happened twice to me and i do think it is a very dangerous situation. i have been told this is by design but if it is ,it is a poor design. *tr
I purchased a new 2010 toyota prius in september 2009 from darcars toyota in frederick md. i have experienced (2) instances of unintended acceleration during the time since i purchased the vehicle. i have informed darcars toyota and toyota corporation. darcars ran a "health test" on february 4, 2009 on my vehicle and the test indicated everything on the vehicle was operating normally. darcars then contacted their toyota california (tac) and related my problem to them. the response from toyota was that my episodes of unintended acceleration was just the abs system engaging normally. this is after the press release from toyota corporation on the morning of 02/04/10 acknowledging a problem existing with the 2010 prius but claiming to have already fixed the problem on all new 2010 prius automobiles sold since january 2010. my two questions are 1) if toyota discovered a problem with the 2010 prius that they supposedly repaired on all 2010 prius vehicles sold since january, why has toyota not contacted me about what is an obvious safety issue? i have owned and been driving my 2010 prius since september '09. 2) what is the specific repair that was supposedly performed on all 2010 prius automobiles since january 1, 2010? why did my toyota service manager have no knowledge of such a repair? was there a safety bulletin issued by toyota? why has toyota not already agreed to repair my 2010 prius (sold in september '09) with the same repair allegedly already performed on 2010 prius automobiles sold after january 1, 2010? *tr
Tl* the contact owns a 2010 toyota pruis. the contact stated that while driving in reverse with her foot on the brake petal, the vehicle accelerated on its own. the contact then applied the brakes and it stopped. she then turned off the vehicle and it drove normally. the issue has occurred a total of 5 times. the vehicle had not been diagnosed at the time of the compliant.the dealer will be contacted. the failure mileage was unknown and current mileage was 2500.
My 2010 toyota prius does not always recognize the key and will not open doors and not start the vehicle. the gear shift jumps out of gear going from reverse to drive and vice versa. the heater does not work properly. i am afraid to drive my newly purchased vehicle. please advise. *tr
I bought a 2010 prius in september 2009. in october, i drove over a pothole that was about 6 inches deep and covered the entire width of the lane. here is what it felt like happened: when the back wheels hit the bottom or the top of the pothole, my car suddenly accelerated and i had a very difficult time stopping it. i managed to not crash into the car in front of me, but just barely. it hasn't happened since. the pothole was apparently the result of work on the road, b/c it was squared, like the pavement had be intentionally cut. *tr
The brakes on my 2010 toyota prius at times do not engage immediately. it may be necessary at those times to depress the brake pedal by 1/3rd before braking begins. there is a similar delay when braking is used to turn off cruise control. neither of these have caused an accident, but in both cases there is some risk.
On 7 different occasions since purchasing our toyota prius 6 months ago, while pushing the brakes, the car has lurched forward as though someone pushed down on the gas. *jb
Tl* the contact owns a 2010 toyota prius. the contact stated his vehicle accelerates on its own when he steps on the brakes. the contact took his vehicle to the dealer and they stated there was no problem with the accelerator pedal. the contact stated he heard about the problem on the news and he was reporting the problem. the failure mileage was 2,010.
Toyota prius 2010. problem reported to dealer 12-18-2010. brakes become inoperative when passing over uneven surfaces, vehicle also at this time vehicle lurches forward. this occurs frequently. contrary to your form requirements there is no one "approximate incident date". shifter sometimes is difficult to put into neutral, rather it will instead go from drive to reverse. if there is also a sudden acceleration problem, this could be a big problem when trying to regain control. *tr
I have a 2010 toyota prius and it accelerates randomly. usually when i push on the brake a little bit, but not all the way, it will jump forward and accelerate. i heard about the issues with the mat and i removed the mat months ago. its is still unintentionally accelerating. it has happened may 6 times since i bought the car in july. i am scared to drive it and have been driving my spare car until something is done by toyota or someone else that cares about the safety of drivers. *tr

I have a 2010 toyota prius purchased in july 2009. during ownership i experienced when there was a crease, hole or bump in the road when braking - it accelerating and lunges. i avoided situations like that and when the recall came, i took it to butler toyota (also had the floor mat hooks installed prior), on april 5, 2010. they supposedly fixed it. about a week later, i came upon a manhole cover in a road while braking and making a turn so going slow, and the same thing happened. the next day i purposely went through it to "test" and it did the same thing but lunge into the other lane. i was scared and called butler toyota. they told me to call national toyota to report. they contact butler and i went back in may 21, they did not repair it and "shrugged" their shoulders saying it's the abs. they offered to have a field tech person come drive my car. i called national again and they seem to be "mediating" this with butler. i found a report from consumeraffairs.com that this very similar issue was occurring back in 2008 and they called it "traction control". no one from toyota has told me this. i want it fixed or a different car. i have a teenage with a permit and if he was driving this and it occurred, he would probably run into someone because it takes you by surprise. i do fear him driving it due to his inexperience and i frankly am concerned and am very cautious as a result. *tr
My new 2010 prius accelerated on it's own as i was braking and slowly approaching the car in front of me that was stopped at a stop light quite some distance away. my car had almost come to a complete stop when suddenly the engine revved on it's own as my foot was still on the brake. i had to press down so hard on the break to keep it from surging forward that the abs light came on and then the car's rev went down on it's own and all was back to normal and hadn't happened again since. i brought the car to the dealer and they kept it for two days but didn't find anything wrong with it. i have two small children and bought this car for a number of reasons, safety being one of the important ones. i am no longer feeling safe. this was not the floor mats, or a sudden stop mistaking one pedal for another, or any other form of driver error. this was the car! please help to discover the cause and make toyota fix it before someone gets hurt or killed. thank you, chris toppin *tr
On three occasions, while driving on clean, dry road surfaces, my 2010 prius suddenly and briefly accelerated without any warning after i drove over minor bumps and, one 1 occasion, a manhole cover, while braking. the sensation was that of the engine suddenly surging and accelerating. i was fortunately able to apply harder pressure to the brake pedal, regained control of the vehicle and avoided crashing into the car in front of me. i spoke with a toyota field technical specialist today who told me that the mechanics of the car are such that if a wheel hits a bump or moves onto a surface that causes it to rotate at a different rate versus the other wheels, the car thinks it is going into a skid, and the abs system kicks in. also, the system that generates energy to recharge the battery, which also effectively brakes the car, suddenly ceases to operate. consequently, you have the sensation of acceleration when in fact, according to the toyota specialist, the car stopped decelerating. nonetheless, this sudden deceleration is unexpected, and if i was not focused at those exact moments and failed to immediately apply significant pressure to the brake pedal, i could have easily crashed into an object, or car, or person, in front of me. i do not feel safe in this car, and am worried that my wife or son could have a major problem responding to this sudden lack of control. there is great potential for serious injury or death from this type of incident. my car is about 1 month old, with 1,250 miles on it. i understand from the specialist that toyota dealerships on long island have had at least one other similar complaint. *tr
As i was approaching a stop light, i took my foot off of the gas pedal of my 2010 toyota prius to hit the brake when all of the sudden my vehicle accelerated and surged forward. it did not stop until i slammed my foot on the brake. this has not happened since and i had assumed it was a freak accident, but i wanted to report it in light of the toyota recalls that have occurred. *tr
Problem is onset of acceleration when brakes applied in 2010 prius 4, purchased at antwerpen toyota, clarksville, md in august 2010. problem has been detected 2 times, without accident, but with significant increase in anxiety. both incidents were approaching a stop sign, and seemed to be related to change in acceleration due to rapid braking. first incident in september 2009 was considered a 'driver issue' since i had owned the prius only 1 month. however, second incident in november 2009 was clearly not a driver issue, and was initiated the same way--stopping at a stop sign after driving at highway speeds for some time. neither incident involved a traffic accident. *tr
The car, a 2010 prius, accelerates forward when going over a bump in the road or a pothole, as the brake is applied. the problem occurs at an unpredictable frequency. the consequences are that i lose control of the car's speed. i have reported this problem to my dealership several times since purchasing the prius and they have found no problem, stating there is nothing to fix. i have been very concerned about the problem, even before the recent events in the news about toyota. had i known about this site, i would have registered the complaint earlier. *tr
2010 prius which lurched forward each time i hit a certain pothole while braking. i avoided the problem by avoiding the pothole. the pothole was located near a stop sign, so i was always braking when i hit it. *tr
Tl*the contact owns a 2010 toyota prius. the driver stated that she recently had a recall repair performed on her vehicle for the acceleration; however, she continued to experience the identical failure. when she drove over a bump in the road, the vehicle accelerated on it's own. she called the service manager and she is waiting for a return call from him. the failure mileage was 500. the current mileage was 8,000.
