I am describing a repeating issue with my 2007 Toyota Prius. This failure occurs when I drive over bumpy surfaces, a large pothole, or an area with a dip in the road. Often, when faced with these conditions, the car stutters and lurches and the vehicle stability assist light flashes. At times, the car's slip and stutter seems to last several seconds after hitting the rough patch in the road. While it seems to exacerbate the problem if I am turning or braking, I should point out that I sometimes experience this lurching and stalling sometimes when I am simply driving along at 35 mph and hit a pothole. It often seems to occur in a situation where braking or turning is involved, but it seems more related to the vsa process. I am reporting this failure because I have seen news reports of an investigation of the 2010 Prius model. The description of the brake failure reported in the media are basically the same as mine.

I have a 2007 Prius the following has occurred any time driving over rough patches of road or over rr tracks: The car loses traction and power for a sort time until smooth pavement returns. The vsc lamp on the dash shows up when this happens. I shudder to think what would occur on a rough mountain road or in wet weather. This type of event sounds very much like what's being reported by the drivers of the 2010 Prius. In 47 years of driving I've never had a car react in this way. I've compensated by driving cautiously and wait for traction to return but it doesn't feel quite right when it happens.

The braking issues that I have experienced for the 2007 Prius within months of buying the vehicle are the same issues that are currently being reported for the 2010 Prius. I have a Prius with traction control. There are two things with the traction control that happen on a regular basis living in St. George, Utah. One is when I come out of a parking lot that has the steep dip for water control the traction control system misfires on dry, clean surfaces and in many cases leaves me dead on the road for a few seconds in which the car will not move at all. This also happens when I drive on roads where there is a drainage lid in the middle of the road, and I am actually not attempting to brake. The second is when I brake. If there is any rough or uneven surfaces, bumps, or dirt roads, I have to anticipate that the braking system will fail and/or I will have to quickly pump the brakes and leave extra braking room. I have not taken the vehicle to Toyota because having had a 1999 Tacoma whose brakes would fail on a regular basis to the point, for which they continually replaced sensors, I sold it after I had it less then one year, I don't expect Toyota to do anything about it. I just drive differently. The speeding out of control, for me, only occurs when I have cruise control on. Many times when I press on the brake the car actually speeds up with a jerk or I will look down at my speed and cruise control will have increased it by 10 or 15 mph.

My 2007 Prius has the brake problem identified on the 2010 models -- when I go over a pot-hole or bump the brakes "slip." This probably happens once a month and has happened since I purchased the car in the fall of 2007. The brakes grab again as soon as I hit solid road.

During turns at times my 2007 pruis will bog down and have no power. I have reported the problem to the dealer and they believe it my be a sensor problem where the ABS senses to much spin and cuts power to the transmission. It takes about 5 to 10 seconds to get the power back to the transmission. During this time the car cannot move.
