2010 prius seems to lurch forward when driving over potholes and other bumps while braking. This has happened near intersections and when turning into parking lots. The car seems to speed up briefly, enough to scare the driver. I've almost rolled through stop signs and nearly run over a few cars when turning into parking lots.
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).
I purchased a 2010 toyota prius on 8/26/09. The car would accelerate when I stepped on the brake to slow the car down at a stop sign or red light. I brought the car to plaza toyota on 12/23/09 after this occurred more than 50 times. Toyota told me that there was nothing wrong with my car and I'm the 1st one to complain about this problem. On the receipt (r/o # 6311675/1) from this visit, toyota stated," tom the toyota field tech determined that the feeling that the customer is experiencing is normal and that the regenetive braking system and hydraulic system is transferring and that's normal." since that visit, this problem has only happened 4 times. In regards to braking on slippery roads, the car has slid 2 different times before gripping the road. Also, toyota claims that the prius gets 51 mpg, this car has only been averaging 33 mpg in city driving.
We own a 2010 prius. My daughter usually drives it. I had it for the month of january. During that time, I experienced brief surges or swerves when I hit potholes or rough spots in the road at a slow speed. This occurred 3 or 4 times out of approximately two dozen short trips around town.
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.
Was parking on slight incline facing downhill. Hit brake to put car in park, but car lurched forward, over concrete bumper in front of parking space. Just happened, have not taken corrective measures yet. Also have noticed car lurching forward when slowing around turns, has not caused significant problems yet, no action taken yet.
There have been several instances since I purchased my 2010 prius in october 2009 that I have gone over a bump in the road and my 2010 prius has felt like it's speeding up and I had to push hard on the brakes to feel like I had control of my car.
Since purchasing my 2010 prius in august, I have experienced multiple episodes of car feeling as if it were suddenly accelerating when going over bumps, potholes or other irregularities in the road. I believe when this happens I often already have my foot on the brake, but I find myself having to slam the brake on harder to prevent what is at least a strong sensation of the car "taking off". Feels just like when riding a horse and it is about to bolt! Went to dealer in september or october, and they completely blew me off, said "nothing is wrong", no other reports of this happening (clearly a lie it now appears).
The brakes momentarily release/skip when bringing the vehicle to a stop while passing over a bump or pothole in the road. This has been happening on a regular basis since I bought the car in july 2009.
I purchased my 2010 toyota prius in december 2010. Twice in the last two weeks my car has unexpectedly lurched forward as I went over a speed bump at a relatively low speed. Since it was the same speed bump both times, I reason that it must have something to do with the height of the bump and/or my angle of approach. I was able to regain control of the vehicle both times. I am reporting this because I have read the news articles about others having similar problems with 2010 prius' and thought that you would want to know. I have not taken any action because I wasn't sure the problem was with the vehicle or the road surface.
I have a 2010 toyota prius. Approximately 10 times since I bought the car in july 2009 it has jolted forward while I am applying the brakes when I drive over a pothole or bump in the road.
I own a 2010 prius, and have experienced an acceleration issue on about 3-4 occasions since purchasing the vehicle in august of 2009. The issue I had was perfectly described in a recent on-line article from money.cnn.com on feb 3. Here is the quote - "the complaints received via our dealers center around when drivers are on a bumpy road or frozen surface," a toyota motor corp. Spokesman in japan, said. "the driver steps on the brake and they do not get as full of a braking feel as expected." this is exactly what I've experienced, and it also seems to possibly be related to the shift from gas to electric which occurs when slowing down. After braking, there is a sudden, brief surge of acceleration. I have not brought this into the dealer, but plan to soon.
We live in chicago and own a 2010 prius. We also have experienced the acceleration (forward surge) upon braking on uneven terrain reported by other owners. No accident, but it happens often on our city streets and it is a little unnerving. The last time it happened was yesterday.
When driving my 2010 toyota prius the car has a tendency to accelerate forward as I am hitting the brakes. I have noticed this is usually around potholes or any other bumps in the road. It happens pretty regularly and it scares the pants off me; to say the least. I have found no response from toyota concerning fixing this problem and am worried that when something bad happens I'll be held responsible for their mistake.
Toyota prius 2010, sudden surge of power, when slowing or braking to come to a stop. Extremely dangerous in traffic or when parking. Have reported to toyota, who claimed no knowledge of prius's having this default. Another said this was a common function of the hybrids. Recent service dept. Claimed checked but found no evidence. This problem happens intermittently. Because we know of this problem, are extra cautious.
2010 prius accelerates when driving over speed bump, pot hole or other uneven surfaces.
Sudden surge when hitting a bump at medium speeds. My prius is now six months old with about 6,000 miles on it and I experience a surge in acceleration when I hit a bump at about 20 MPH. I used to be an auto mechanic (20 years ago), so I may be a little more attuned to narrowing the problem than most people. I have noticed that when this surge happens I am lightly on the brakes (totally off the accelerator). This seems to particularly happen when the bump (like a pothole in the road) is under the right front wheel. Even more frustrating is that this does not happen every time nor on every bump. I can tell you the floor mat has nothing to do with it and I do not think the outside temperature has anything to do with it either. My shadetreemechanic's diagnosis is that this is a software glitch that gets activated when the braking solenoid is bumped.
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.
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.
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.
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.
I drive a 2010 toyota prius and would like to report that when braking, if I hit a pot hole or bump, the car lunges forward or accelerates for a split second. I have had my car for just under 60 days but have had this experience at least a dozen times. It has not caused an accident, but leaves me feeling as if there are moments that I do not have control of my car. It's like it has a mind of it's own!
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 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.
I have a 2010 prius. I have had 2 occasions where I have hit bumps in the road and my car accelerates without me touching the gas pedal.
Tl* the contact owns a 2010 toyota prius. The contact stated when depressing the brakes to stop the vehicle it is grabbing and jerking. While using the vehicle's speed control upon setting it the vehicle would accelerate, but when the brakes are applied the vehcile would operate normally. The contact stated that he monitors the failures. The vehicle has not yet been diagnosed by the dealer.the failure mileage 6,200.
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).
I saw an article about the 2010 prius lunging when hitting a bump or pothole. I own one and have had the experience on more than 1 occasion.
