My 2009 toyota prius brakes are faulty. The brakes do not respond properly, especially on slippery roads and on a decline. I took the car into the dealer in 10/2010 and they didn't find anything. I changed all 4 tires on the car in 2/2011 and still experienced the problem. I took the car into the dealer on 5/24/11 and again they did not find anything. They mentioned "abs system" and implied that i was experiencing…

I have had more than 10 occasions of braking problems with my 2009 prius. Most recently, in january 2010, but also prior to that. After the last problem, i called the local dealership to see if a brake recall existed but was told "no" only recall for floormats on my model. The issue has occurred on pavement and gravel road, in school zone, traveling at less than 20 mph. When slowly pulling up to stop sign and…

Service Brakes, Hydraulic · Traction Control System
2009 toyota prius vehicle slid into intersection, no collision occurred. Approx 3 ft past stop point. During moderate to hard braking, if a wheel hits sand or a pothole, the "traction control" system engages, causing the brakes to release for approx .25 to .75 second. It is very unnerving (to say the least) to be out of control of my vehicle. It is also repeatable when accelerating on a short entrance ramp around a…

2009 toyota prius - delayed braking has been experienced several times. Seems to be related to hard braking. It only last about a second but is very unlike any other car i have driven. I had passed it off as just something weird but then i heard others describe it on the tv and i said that happened to me too!" as a safety engineer in the aerospace industry, it does seem to be related to the delay from switching from…

The problem is that our 2009 prius at times seems to accelerate momentarily when the brakes are applied. My wife and i drove this car for eleven months and didn't realize we had a problem until i had to drive the car during the start of the snow storm with 2" of snow. I was going down a hill that i have driven on in different cars a number of times in the snow. With the prius, everytime i applied brakes to keep the…

Service Brakes, Hydraulic · Traction Control System
2009 toyota prius. Strange behavior of antilock brakes/traction control system when hitting a single pothole or small patch of ice on otherwise clear road surface. Vehicle significantly dampens brake response and does not recognize that the tires are now on a good contact surface and continues to be in tc mode for excessive time period. Only way to assure you will stop within reasonable distance is to lift up on…

Continual problem whenever we try to brake, the car will begin to accelerate. This problem has been apparent since we purchased the car and each time we mention it at the servicing, we are told the brakes are working fine. *tr

The braking problem that has been reported in the 2010 prius is not limited to that model year. I have a 2009 (2nd generation) prius and i have at times experienced the same slight braking problem when going over a bump or a railroad track. *tr

On dec 11, 2009, i was driving down a street in cambridge, ma (i had a coworker in the car) and we were in stop and go traffic at a stop light. The car in front of me crawled up to approach the light after several cars had gone through-then stopped @ the red light. I proceeded to do the same. When i applied my brakes to stop there was no response, so i pressed down harder-still no response. I then began to pump my…

2009 toyota prius while driving on uneven pavement or icy roads, when depressing the brake pedal the car slides and it feels as if you are losing control over the car. This happens on any uneven surface like speed bumps and or wash board roads, and during the winter months for icy roads. I have an appointment with toyota in colorado to fix since it is still under warranty but they say no recall has been initiated on…

2009 toyota prius. When braking the brakes would disengage temporarily causing the car to go faster. I have come real close to rear ending the car in front of me during adverse road conditions. I have driven for 35 years in snow and slick conditions and i know when a car isn't braking right. I always maintain a save distance and this is the only car that has done this. This scarier part is that this happens every…

I am an owner of a 2009 prius. I have experienced from day one, an issue when braking over a bump or pothole in the road. The brakes do not grasp. A picture of a swirving car appears on the monitor of the car showing out of control vehicle. This appears to be the same problem as the 2010 recall. Please recall all affected prius' which now include 2009.

Electronic Stability Control · Service Brakes, Hydraulic
I have a 2009 prius. I've been complaining to friends and family, since i got it about six months ago, about its instability when i go over small bumps and ruts in the road. The car seems to surge ahead, swerve a bit, and lose contact with the ground. The other major problem is the car's horrible traction on wet highways. If i'm traveling over 45 m.p.h., my car begins to hydroplane. The experience is unnerving. I've…

Multiple issues with 2009 prius. First: loss of air pressure in front left tire from time i picked up the vehicle to present. I continually need to put air in the tire, usually on a weekly/bi-weekly basis. The other tires are fine. Second: for the same tire, the tire pressure light would not be triggered until ~23 pounds, should have been triggered in same tire at 33 lbs. Third: vehicle would not stop when applying…

Driving car on los angeles freeway during a gentle rain. I was going slow and a car cut in front of me and when i went to brake, the car began to accelerate. Took car to hamer toyota in mission hills and they tested the car and said the brakes were fine. Today's headlines that i am not the only person that is experiencing this problem makes me all the more concerned. *tr

I bought my 2009 prius in april 2009. I have been having the same brake slipping problem that the 2010's are being recalled for. I have had my car to the dealership three times to have this problem addressed. Each time it was no fault found and "gosh these brakes are complicated and you would have an idiot light go off if there was a problem". I am feeling very unsafe with this vehicle and want to know when my…

I have a 2009 toyota prius, and the brakes do not always engage. There have been several instances where i felt that the car would not stop, one time i even engaged the emergency brake to stop it from going into my garage wall. I have had it into my dealer about 4 times, and each time they haven't found any problem and that "it is just the way the car works" .*tr
