2010 Toyota Prius. Consumer states two brake system failures the consumer stated the vehicle began making an unusual sound and after a few days, numerous warning lights appeared on the dashboard announcing a failure of the braking system. The vehicle was towed to the dealer. An inspection revealed the master cylinder, booster and ecu needed to be replaced. The consumer paid $ 3,246. 83 for the repairs. However, nine days later, the unusual brake pedal sound returned, but the brakes worked and no warning lights appeared. The next day, the brake system completely failed while his daughter was driving the vehicle. Again, the vehicle was towed to the dealer, where the technicians determined the vehicle needed a new brake booster assembly. The consumer was informed he would only be responsible for the labor costs of $ 255. 48. The consumer believed the booster and brake booster were the same part, which was supposed to have been replaced several days prior. Jb.

I have filed a complaint here before about my 2010 Toyota Prius, where the brakes were supposedly fixed last week by Toyota following the recall. However, just today the braking problem, when hitting bumps in the road, seems to not have been fixed at all. Driving in the DC area, where there are a lot of potholes around, it is easy to test whether the brakes are fixed or not. While driving along the road today, nearing my house, I hit a pothole, and just as it had been happening before, the brakes seemed to completely let go and the car lurched forward for a split second until the brakes seemed to regain power and I was able to press down on them again. Prior to that incident, and not 10 minutes earlier, I hit a small pothole while braking lightly and the brakes gave out just slightly. It's an unmistakable feeling, having experienced it numerous times before Toyota finally decided to recall the 2010 Prius. Updated ivoq 07/08/10.

2010 Toyota Prius iii. The consumers daughter was involved in an accident. The brakes did not stop the vehicle when they were applied. She collided with the vehicle in front of her, which then hit another vehicle.

I own a 2009 Toyota Prius and am experiencing the same problem with braking that the 2010 Prius' are having. When braking on an uneven or bumpy surface, it seems like there is a momentary pause or hesitation.

Our 2010 Prius sometimes lurches forward on hitting a bump or driving on rough terrain. This happens predictably at certain locations. Both my wife and I have observed this behavior, maybe a couple of times/week. Not certain whether it's momentary acceleration or loss of braking but we think it's loss of braking. We have not yet taken any corrective action. I read in the paper that Toyota is planning a recall.

I've owned my 2010 Toyota Prius for 5 months now and frequently (at least twice a month) experience problems when braking on uneven ground. When I am hitting the brakes and run over a pothole or sudden bump, the car stops slowing down and almost shoots forward (feels like I'm hydroplaning) for a split second then resumes braking. This happened most recently today and could have caused an accident if I were closer to the car in front of me when it occurred.

My 2010 Prius lurches when I go over pot holes or rough patches. I can control the lurch, but it does not feel right. It does not happen all the time. I am not sure what makes the difference between it happening and not happening. I received the title to the car in 8/27/09.

Toyota Prius brake loss of control - when the vehicle goes over a bump (e. G. Pothole, manhole) when the brake is being applied, it doesn't immediately stop but instead seems to lurch forward with the sensation of loss of control. This especially happens on city streets or in icy conditions. If there was a person or car in front of the vehicle, the Prius would have hit the person/car. This happens every day at the same stop (bump in road when turning), as well as random places at least weekly since purchasing the car in September 2009.

When our 2010 Prius goes over a bump the brakes seem to disengage and speed feels like it is increasing. Althouhg todays date is on the event this has been an ongoing concern since purchasing the vehicle last year.

2006 Toyota Prius. Braking behavior identical to what has been described in the 2010 Prius models. When traveling over a rough patch of pavement or potholes at low or moderate speed, the vehicle braking seems to release. The best way to characterize this is that as the vehicle bounces over the rough pavement during breaking and the weight is applied and released from the wheels due to the up/down motion, the brakes release and re-apply inconsistent with the steady pressure I apply on the brake pedal. This is beyond the behavior expected by the abs. No accident or damage has yet occurred, but the behavior is disturbing. Not meaning to pile on with the ongoing troubles with Toyota, but the description of the braking in my 2006 vehicle is identical to what is described in the 2010 Prius model.

Whenever I am driving and hit a pothole or bump on the road, immediately after going over the pothole or bump I feel like my Prius surges forward or speeds up. This happens whenever I am going at a constant speed or when I'm braking. It has happened since I bought the car (two months ago) but yesterday morning it scared me more because I was going over a really bad road with many bumps. As I approached a red light I began to brake early but as soon as I got close to the stop there was a bump before it and my car lunged forward causing me to stop past the white line of the stop sign. This happens all the time when I hit a pothole or bump on the road.

When my 2010 Prius goes over bumps the brakes disengage for a second or two and the car lurches forward. This has happened several times.
