Just adding fuel to the fire, but I have a 2010 Toyota Prius and there is definitely a braking issue. Specifically, I notice it when I hit a pothole (and I live in los angeles, which is all the time). I frankly don't know whether there's actual acceleration or just total loss of braking (I basically notice it at slower city speeds--braking while turning a corner, for example), but there is definitely a momentary "surge." It happens regularly (ignore the date I had to enter below)--so much so that at this point I anticipate it.

2010 Prius purchased July 2009. Turning into my driveway while braking (which had a pothole in front of it) my car felt like it was lurching forward out of control after it hit the pothole. I would have thought that the pothole would impede my forward progress not increase it! I was going very slowly so the incident was momentary, but it did scare me. This happened several times before I learned how to avoid the pothole. I thought it was very strange but once I started to avoid the pothole I forgot about it. So I did not pursue it until I read the descriptions of the rough road complaints and realized that was exactly what had happened to me and that I should report it here. The dates, time and mileage are actually unknown because I did not make a note of it at the time.

When driving through an alley, at the end, before I stop for the street, there is a pothole. Twice I hit it while braking for the stop sign at the street and something felt weird, like the brake didn't quite hold. Honestly I thought I moved my foot from the brake or something. I think it may have happened one other time. I am conscious of if because I wanted to be aware if I was doing something wrong so I could correct it.

Every time we drive down a hill near our house and hit a pothole/crack in the road, the 2010 Prius seems to accelerate through the pothole even though I am breaking down the hill. This has happened since the first day we drove the car (in August 2009). There have been no accidents or injuries since this road is not heavily traveled, but it makes me hesitant to drive my car if I have to go down that hill.

1. we purchased a 2010 Prius six months ago. We have had four incidents braking where we feel the ABS over-compensates when the wheels are on different surfaces (e.g. gravel/pavement, puddle/pavement, etc.). two of the four incidents are notable because it felt as though I had lost control of braking and I was going to 1. rear-end another car and 2. go off an embankment. I am not an aggressive driver. Today, I was alarmed to learn, --reported in the news--that other drivers are experiencing the same issue. Toyota has checked out my car (at the 5,000 mile oil change), but reports nothing wrong. Something is wrong! if feels as though the ABS over-compensates on all four wheels when the surface under one wheel is "irregular" and causes the ABS to react to slipping/sliding. I've owned six cars with ABS, but none of them gave me the feeling that I'd lost control braking. There is something wrong with this car's ABS and I am concerned that Toyota will not address it in a prompt manner. Your auto-fill form requires that I specify a date of incident. Four times, between November 2009 and January 2010, we feel we've lost control of our ability to brake this car at very reasonable (braking) speeds and distances. It's not just one incident.

Approaching a four way stop sign in my 2010 Prius, I applied the brakes but the car continued for approximately a second before the brakes took effect. There was patchy ice on the road before the stop sign. I went through the intersection, past the stop sign by about 20 feet. I originally thought it was just the ABS braking characteristics however now I realize it was an actual delay in the breaking itself. I drove my previous 2004 Prius for 108,000 miles without ever having this occur.

Hitting a bump while braking causes the brakes to not work properly for a split second, giving the feeling that the car is lunging forward.

When applying brakes, to my Prius 2010, on at least 3 occasion the brakes seem to fail. Applying more pressure doesn't seem to work right away, then the brakes grab hard. Only noticed at slower speeds, and rougher roads.

I want to register a complaint that I am experiencing loss of braking in my 2010 Prius when the car hits a bump or pot hole in the road. Have been in conversations with Toyota personnel. No satisfaction to date with possible fix. No accidents have occurred thus far with my vehicle. It has occurred several times, most notably since the roads are getting rougher as a result of winter.

I have a 2010 Prius III with brake issues. Sporadically, when driving backwards from a parked position the brakes become incredibly sensitive and I have to turn off the car and turn it back on again for them to function normally. On about 01/17/2010, after a heavy rain, when I was again pulling backwards out of my driveway my brakes made a grinding sound as if the pads were gone. Mind you I have less than 9,000 miles on the car. Again, turned off the car and back on to fix. Has not happened again but it hasn't rained either.

My 2010 Toyota Prius was a week old. I was exiting on a sloping downward ramp from lake shore drive in Chicago and getting ready to stop and turn right. Road conditions were wet and cold but not icy. I applied the brakes and the car failed to stop. I pumped the brakes several times before they "grabbed." Luckily there was no car in front of me or behind me. If there had been a car in front, I would surely have rear ended it. I thought being a "new" Prius driver I had done something wrong but it definitely caused me some panic. I now have 456 miles on the odometer. The brakes have not slipped since the first incident but I have been very cautious in applying them in similar situations.

There have been 3 instances where the brakes of my vehicle briefly stopped working effectively. These instances always occurred when I was attempting to brake over rough pavement or potholes. It has not resulted in an accident for me yet, but having just read that this is an issue for the 2010 Prius, I thought it important to report that I too have experienced this problem in my 2010 Prius.

Car did not brake properly and slightly surged forward on many occasions when I drove over a manhole cover and speed bumps at lower speeds. In one occasion, I rear ended a car and cracked my license plate frame but since there was no further damage on any of the cars involved, we agreed to drive away.

Our 2010 Toyota Prius surges (accelerates) for a fraction of a second whenever the brakes are applied as it hits a small bump or slick spot in the road. This hasn't caused any accidents, but we drive the car primarily at low speeds (40 mph or less) and haven't been involved in any situations (yet) that required evasive action. We are concerned that, at higher speeds, or in a case where someone pulls out in front of us and we have to apply the brakes quickly, the vehicle will not respond appropriately. I have told my Toyota dealer about this problem twice, and they have no response. About what to do about the problem. All they said was that the car has not been recalled, and that I should touch base with them periodically for updates. They took my name only when I pressed them to push the information back to Toyota management.

I have a 2010 Prius bought in September. I have experienced the surge while braking about 4 or 5 times in 5,000 miles of driving. I didn't connect it with braking as it was a surge. I think that the roads were wet each time this happened. I stepped down hard each time and the surge disappeared after about a second or so.

When driving my 2010 Prius over bumps with my brakes on, the car lunges forward as if the brakes are not working. This occurs each time I hit a bump when I have my foot on the brake pedal.

2010 Prius brakes appear to become inoperable during transition from electromagnetic to hydraulic braking. I've had this occur an three occasions, twice during aggressive braking (near misses). Once this occurred at low speed on a patch of so-so road during light rain. The other two times this happened at 40+mph on very good dry road. I took my car in to my local Toyota dealership yesterday to evaluate this concern and was informed that my brakes are not malfunctioning. The dealer seemed unaware of the issue and the fact that Toyota had corrected this issue in the cars currently coming off of the assembly line. The dealer position seems to be that the Prius brake system is advanced and does not operate like other brake systems. My position is that brake system design should not contribute to driver panic during aggressive braking.

The issue with the brakes on the 2010 Prius has occurred several times on our Prius, which was purchased in August of 2009. Coming downhill and going over a speed bump there is a sudden slight acceleration when we apply the brakes. Fortunately, no accident has occurred.
