I own a 2010 toyota prius, and like many have experienced the brakes "cutting out" when slowing down and going over a rough section of road. I drive throughout the houston, texas area and have had this issue happen many times, usually unexpectedly. There are a few places I drive regularly that create the issue and I anticipate them and adjust my driving accordingly.

2010 toyota prius with 2500 miles. Since purchased on 8/2009, I had more than ten experiences of unexpected acceleration (sudden unintended acceleration) on reverse that feel like two or three time (stronger) faster than normal reverse. Accompany the higher speed reverse, a heavy, abrupt braking with a slight touch of the brake during this event. The big "jerk" (braking) rock the entire car and banged heads again the headrests.this only happened with electric mode and most time with the car parked a slight incline. This unintended acceleration sometime happen a few time a day or it can go two, three weeks without any problem. The dealer can not find anything wrong with my car. And toyota have no information about this problem. However, if you go to priuschat forum under gen iii 2010 prius main forum-braking in reverse, there are many people with the same problems. I strongly believe this is very dangerous if a new driver get in my car and not know about it. There is one post in priuschat forum that best explain the problem: just yesterday, my prius-iii backed up with sudden unintended acceleration, with my foot only on the brake pedal.... I recognized what was happening because it happened once before, just over 2 months ago. Just a few days after I got the car. When I was backing out of an inclined driveway... I suspect that some unusual element of the timing of turning the car on and shifting into reverse, and possibly the internal state of the computer and the hybrid power system combine to produce this "abrupt" reverse acceleration as I am gently easing off my foot pressure on the brake pedal... The abrupt braking effect does occur, but only in response to the much more dangerous "unexpected, unintended" reverse power (acceleration), to stop the car motion. No matter how gently the brake is eased further on to stop, the stop is "abrupt" by garygid orange county, ca. I am trying to work with toyota on this issue. Thank you.
2010 prius "freewheels" if you hit a bump while braking. This occurs every few weeks. Nothing has been done to correct.
Momentary brake failure.
I have a new 2010 prius ii with only 2500k miles on it. Now three times for me and once for my husband we've had problems getting the car to stop/slow down while applying the brake on wet railroad tracks and prior to approaching a patch of ice in the road. You press the brake expecting it to slow down. Instead a helplessness takes over as you feel as though the car has suddenly gone into auto pilot and you go sailing on as though the brakes never engaged and you instead hit the accelerator. Thank god I'm a cautious driver and have never in 44 years had an accident of any kind but, even my defensive driving skills would be useless if the car does not do what I'm telling it to! I use this car daily to transport myself and two small children and now I'm scared to death to drive it. I was glad my husband had it happen too. I had not told him when it did it to me and the look on his face as he turned to me going over wet railroad tracks and said "did you feel that?" I felt validated knowing that it wasn't just me. Today while with my mom and the kids I slowed down to navigate over an unavoidable patch of ice in an intersection. Thank goodness no one was in front and the oncoming car attempting to turn left didn't go because I applied the brake and we just sailed on through, barely making the turn that I needed to make just beyond the intersection. My poor mother said, "did you mean to do that?" had any car or person been in the way I have no doubt I would have hit them. This is my first new car in years and now I'm petrified I'm going to crash it and hurt my family and others. This has to be investigated asap. Please help!
I bought my 2010 prius in july 2009. Since then there have been several incidents in which my car seemed to surge forward while I was in the process of braking and hit a bump, railroad tracks or pothole. Initially, I convinced myself I must have been letting up on the brake when I hit the bump but when this same thing happened 3 days ago on slippery, icy roads, I knew for 100% certain I had not let up on the brake. My car surged as I was slowly pulling up to a stop sign and gently braking. I came very close to hitting the car in front of me, had to push down on the brakes very hard, which activated the ABS. The ABS had not been activated in any of the previous incidents because I had not needed to push hard on the brakes as I was in no danger of hitting anything. I have been driving toyotas since 1992 and am stunned that this problem is happening with no fix in sight. The dealership in my town assures us they've never heard of this before, although it is obviously happening all over the country. Please investigate this. I have a 5 year old and I no longer feel safe driving my car with (or without) him in it.
My 2010 prius is only 2 months old & when applying the brakes, at times, it feels like I have been hit in the back by another vehicle and the entire car jumps forward before coming to a full stop. Some what like an engine surge or that the brakes have not applied properly. I have reported this to my toyota service department & they have suggested that maybe it is due to the gas engine turning on or off at that exact moment. I find this to be very dangerous as there is a definite surge forward before the car stops. It has happened on different road surfaces, smooth, uneven & bumpy when both wet & dry. They did not find any solution to this problem & told me to continue to monitor it. They also advised that no recall has been issued or other complaints received.
I was unable to slow down going into an intersection at a reasonable rate of speed. While I was not accelerating, when I applied the brakes the car did not slow down as I would have expected. This same behavior has occurred in the past several months since I've owned the prius 2010 model. It seems to skip forward or accelerate while braking on a downhill or uneven surface. By the time I was able to stop I the airbags had gone off and I had hurt my neck and back. It is a new vehicle that now has almost $14,000 damage and won't be fixed for a month. If anything, I'm an overly cautious driver and wondering what I could have done to avoid the accident.
My 2010 prius v has very jerky brakes sometimes when starting out. Causes all people in car to be jerked around. Many other prius 2010 owners report same problem. Toyota denies knowing about problem in spite of many complaints!
A couple of times when I have applied pressure to the brakes on my 2010 prius, the car has accelerated momentarily instead of braking.
This has happened approximately ten times since we bought our 2010 prius in august. I apply the brakes, the car starts to slow down, and then accelerates briefly. I thought that it was just that the brakes let up for a moment, but the last couple of times it has happened I realized that it's more like the car actually accelerates for a moment. It has happened several times when I'm getting off the highway, on the exit ramp, so I'm going for a relatively fast speed to slowing down. But it happens other times, too--for instance, when I'm driving in the city and stopping for a red light. Tonight it happened and I would say that the car moved forward quickly for about 15 feet. I have had the car checked by toyota who has found nothing wrong with my brakes, but I know that this is a potentially dangerous glitch.
While applying the brakes to slow down or to come to a stop, if the car hits a bump, pothole or the like, the brakes release momentarily, causing the car?s momentum to continue forward longer/further than you would normally expect or want. This is especially dangerous when coming to a stop at a new york city pedestrian crosswalk or trying to slow down with a car close in front of you. I brought the car into the dealership and had it evaluated by toyota's field technical specialist who reported the following, ""when [the car] senses impending wheel slip, it will first disable the regenerative brakes. When it does that it feels like the car sort of accelerates because you lost the regenerative braking and you're using the brake assist that you have from your foot. So that is 'normal operation' on the system. It is working as designed." despite the explanations for why this is happening and whether or not this is ?normal operation?, the bottom line is, if the car is not stopping when it should, the safety of passengers and pedestrians is in jeopardy. I called and wrote two certified letters to toyota's customer experience department and to akio toyota, and received a phone call from an executive analyst from the president's office. No toyota representative would do anything in regards to the problem--they maintain that the braking operation is normal. I have seen other complaints on the federal safety agency web site and on prius owners blogs that contradict toyota's assertion and support the claim that the brakes are indeed a safety issue that must be addressed.
I bought a brand new 2010 toyota prius and left the dealer on october 23, 2009. I had to stop short at one of the stoplights on the way home and noticed a disturbing lag before the brakes engaged. Hours later I was driving down a major highway when traffic stopped suddenly and the brakes would not engage. I rear-ended the car in front of me and modestly damaged the car I hit and severely damaged my new prius. Fortunately noone was hurt. My six year old son was in the back seat.
Please investigate the 2010 prius and its' braking system. While braking on a wet pavement, going down hill or braking when the car goes over an uneven or bumpy service, the car accelerates or lurches forward. Fortunately, I was a safe distance from other cars or could have hit something with this surge effect. The car only has 400 miles and this has occurred at least 4 times, the most recent today on a hill with wet pavement as the car was heading down hill. The brake was gently depressed and the car surged forward.
Tl* the contact owns a 2010 toyota prius. While driving over large and small speed bumps the vehicle accelerated without warning. As a consequence his risk for serious injury and crash were increased. He is in the process of having the vehicle inspected to determine the cause of the failure. The failure and current mileages were 1,000. Updated 09/14/09 *bf the consumer stated on 6 separate occasions , with 2 different drivers, sudden, brief and unexplained engine acceleration was experienced when a bump was hit in the road while applying the brakes. The driver could hear the engine rev up and there was a surge of power from the engine despite his foot not being on the accelerator, but being on the brake. In each of the 6 incidents the consumer and second driver were able to stop safely, bit were put at risk of an accident and/or injury due to the erroneous acceleration. Updated 09.15.09. *jb updated 10/13/09. *lj the consumer stated the cruise control was not engaged and it didn't feel like the anti-lock brakes engaged either. Updated 10/13/09 the consumer also experienced braking problems as well. The consumer stated the problem has greatly diminished. Updated 02/05/10.
