Problems with 2008 Toyota Prius SERVICE BRAKES, HYDRAULIC

I have a 2008 prius that has the same problem as that reported with the 2010. every time i brake on a rippled or bumpy surface, there is a repeated momentary loss of braking. on a certain downhill stretch of road near me, it happened every time i drove it, until it was resurfaced. another problem is that if the vehicle is on an inclined surface of crushed rock, there is a complete loss of power. the dealer describes this as an "overly sensitive traction control system" that cannot be adjusted. this is also hazardous because on slick surfaces, each momentary loss of traction results in an overly-compensated period of seriously reduced acceleration; we have been sitting ducks in intersections, unable to quickly accelerate out of the way if conditions are slick, not because of the surface itself, but because of the way the vehicle mis-handles the situation. *jb

Our 2008 toyota prius has a brake hesitation. this hesitation occurs when going over a rough road surface while braking or slowing. this problem happens often. i have learned that if i keep pressing on the brake when this happens i am able to stop and/or slow down. *tr

Toyota prius braking problems not limited to generation 3 vehicles. i have and 2008 prius (generation 2) that always lunges forward while braking when the vehicle rolls over a pothole. *tr

Every time i am braking and go over a bump in my 2008 toyota prius the anti-lock braking system kicks in. when it does so, it feels like the brakes disengage for a second and the car goes faster, like the braking system is failing before it ends up kicking in. my toyota dealer tells me this is the way it is supposed to work but it does not feel safe to me. it has been this way since the first day i bought the car brand new from the dealer. *tr

I have a 2008 toyota prius that experiences the same hesitancy and shaking while braking that the 2010 recalled models have. i initially took the vehicle to toyota within the first year of ownership and they claimed to not be able to duplicate the problem. they also told me last week at the dealership they have had other 2008 owners state the same problem, but since the vehicles are not under recall, there is no recourse for these cars. i have never had a crash due to the problem, but it makes handling a bit difficult when the brakes shake. i feel the recall fix should be made available to other model years as well. *tr

I own a 2008 toyota prius and have been reading about the 2010 prius braking problem. i am experiencing the same symptons when i hit the brakes on a bumpy or pot-holed section of roadway. it is a temporary (split second) loss of braking power. although i have not had any accidents attibutable to this condition, i am nevertheless concerned and would like the problem corrected. will the nhtsa expand its investigation to include toyota's 2nd generation prius like mine?

Vehicle was hit from rear while stopped at a traffic light. despite the brakes being applied at the time, the rear impact caused the car to be pushed forward into the car in front of it as if the brakes were not even in use. there was minimal damage to the bumper from the rear impact but more significant damage to the front of the vehicle form the second impact. *jb

I have a 2008 toyota prius; it has the same problem with braking as what you describe in the 2010 models. when approaching a stop, if you hit a bump, or pothole, the brakes kind of 'release' momentarily. they do grab again within a half-second, or so. but it is very unnerving. i could see how it could lead to a crash under certain circumstances. *tr

1) the even happens during normal braking from 40 mph over a road with potholes. the location is here: http://maps.google.com/?ie=utf8&hq=&hnear=cleveland,+cass,+missouri&ll=38.67887,-94.675729&spn=0.00139,0.00284&z=19 2) the car loses all braking for 1-2 seconds after running over the pothole. if somebody was in front of me, it would result in a accident. it happens 5 days a week as part of my daily commute. 3) toyota says it is normal for the prius to do this.

I have a 2008 toyota prius. when i drive over bumpy surfaces such as road covers or pot holes while breaking, i can feel my car accelerating mid-brake and then have to press doubly hard on my brakes to slow the vehicle. i was in an accident driving because driving over some bumpy railroad track crossings, i had to break because the car in front of me stopped suddenly. i floored the brakes and my car continued to roll right into the car in front of me. i have also considered that perhaps there was electrical interference with my brakes caused by the railroad crossing. *cn

Pulling into a driveway, my brakes failed to hold, my 2008 toyota prius car jumped forward while my foot was still depressed on the brake, and my car hit a parked car. i reported the accident to my insurance company. damage was done to the parked vehicle; only minor damage was done to my car. i advised my dealership of the incident, and i was told that they could inspect the brakes, but there was nothing else they could do regarding the incident that occurred. *tr

Traction control issues with 2008 toyota prius. the traction control makes the car almost undriveable on snow covered roads due to power being removed from driving wheels. suggest adding a switch to disable the traction control. *tr
