    Has anyone noticed that at times the Prius has a surge of power.I dont mean anything like the crazy stuff that was in the press awhile back about people unable to stop.Sometimes when im just starting to apply the brakes and the car hits a rough patch of road or a pot hole the car get a surge of power and forward momentum.Its only for a quick second,but enough to get the heart jumping.Just wondering if its just my car or something others have experienced.Thanks

    sounds exactly like what people reported in the brouhaha. That is just transition from regen to friction breaking when the ABS kicks in from the change in traction.

    It is not power being applied, but the brief reduction in braking force.

    It's not a surge of power; it's loss of traction. Hitting a bump causes one or both of the front tires to lose traction, forcing an end to regenerative braking and a transition to ABS friction braking. The short reduction in braking effort is perceived as a surge.

    I do not concur.
    Please report it immediately!!! Tell them the G3 is a death trap. Act concerned. Get anybody that you know who drives one to do the same.

    Maybe then the prices will drop some... :)


    Note for the humor impaired: That was sarcasm.

    Wouldn't work. It would hit a bump and stop sticking.

    A small suggestion, it's pretty simple, but to avoid the sensation, if you're braking gradually and notice a bump coming in the road, just let up for that split second, then reapply to keep getting the most energy possible through regen. Once you hit that bump and the traction control kicks in, it's almost all friction brakes even if you wait a couple seconds to start braking again, so to me it's quite worth it.

    Of course, if you really have to stop, I wouldn't suggest letting up on the brake everytime you see a bump :)

    I do this without thinking. I suspect it comes from years of driving on ice and snow.
