    I was driving my 2010 toyota prius (which i'd taken delivery on about january 6), and i noticed what seemed to be a power surge or a momentary brake failure when i went over a pothole while i was slowing down after exiting a highway. The car seemed to lurch forward, so that i had to take my foot off the brake and re-apply it. This happened first on january 20, but has occurred three times since then. I've been…

    I bought a 2010 prius in october. I live in maine where winter driving conditions are not great. I have had three incidents now of driving at a low speed on plowed but snowy roads where the brakes did not catch when i applied them. Once was going around a downhill curve which was scary. Each time they eventually catch but not until i have skidded for about 3-6 ft. Fortunately, i have not hit anyone yet. I called my…

I pressed harder until the brakes were re-engaged. This has happened under similar circumstances (rough road) three times since taking ownership of the car sept 15, 2009. *jb

    When driving i sometimes momentarily feel a pause in the braking system of my new prius. This occurs every time i drive on a certain street at a fairly high speed. While i am braking my right front tire goes through a pothole while my front left tire remains on flat tarmac. As my front tire comes out of the pothole i feel as if the brakes stop working for half a second and then they start working again. I estimate…

    2010 prius brake applied in zero temperature weather approaching a red light on slight down sloping road covered in ice/snow. The brake pedal was pushed as would normally be applied (maybe approx 1/3 - 1/2 brake pedal travel) and there was no applied braking. The car kept rolling forward to where i had to make a decision to continue rolling with a right turn into the intersection and continue travel. Luckily the…
