We purchased a 2010 Prius in May 2010. My wife drove the car out of a shopping mall driveway into the left hand turn of the road and pulled up behind a truck. She was traveling about 5-10 mph on a normal road, no pot holes or wet conditions. She had her foot rammed to the floor but no brakes! she went into the back of the truck, causing extensive damage to the front of the car and windscreen. She had two children in the back with her. Seems like they have not fixed the problem! we were told by dealership that there were no problems and that every car on the lot had been fixed! not repaired yet. Not sure I want it back.

I own a 2010 Toyota Prius. I was having braking issues before the safety recall. It would accelerate when I hit a bump while braking. I told brought my vehicle in for the first day of the recall and it was "fixed." Now the problem is back. My car suddenly accelerates when I'm slowing down/braking and hit a bump.

2010 Prius accelerates while braking and surges in acceleration from a stop while accelerating slowly. Many but not all occasions were while going over bumps and/or wet road. This has happened several times since owning the car. Toyota cannot duplicate the problem in the testing and denies that it is real. It has been brought into Toyota for repairs but the problem persists. The car is now parked and we will not drive it as it is not safe. We filed a lemon law claim (ca) and Toyota has denied the claim with a form type letter.

I had the Toyota Prius reflash done on my car. Since this reflash I have had multiple instances of the brake surge. The most recent incident was yesterday. I was driving down a road going about 25 mph. I noticed an upcoming stop sign and a small dip in the road. I engaged the brakes and slowed to about 10 mph. Upon hitting the dip the car surged forward toward the stop sign and intersection. Despite applying even and steady pressure to the brake, the car suddenly surged forward on its own Accord. We have had multiple instances since the 'fix' by Toyota. We tried arbitration to resolve the issue, but we have been ignored. I am concerned that a future surge will inevitably lead to an accident. This is a definite safety concern that must be addressed!

I have a 2010 Toyota Prius and I received the software recall for the braking system. After receiving the software recall my wife and I have both noticed that there are instances when the brakes do not respond as quickly as they should which is similar to the original reason the Prius was recalled.

I continue to have a loss of braking when traveling over bumpy surfaces, even after receiving the software upgrade that was released by Toyota. This is especially troubling when I am traveling over an extended area of bumpy road, and the brakes won't work as expected.

In my 2010 Prius I have had two incidence with my brake when starting out in reverse. First time was in my driveway, don't remember how long I was in the car until my girlfriend got in.. but when I put it into reverse I got a"stiff" feeling in the pedal and it felt like it wouldn't go down all the way... the car seemed to accelerate back faster than expected when I lifted my foot off the brake.... I lifted my foot and put the brake down and I stopped very quickly (as if I was slamming on the brakes) I then took my foot off and reapplied a few times and the pedal felt fine. We then drove to the local market.. I sat in the car with the acc mode on for about 5-8 minutes while she went in... when she came out I started the car, went to back up and the same thing happened.... this was very disconcerting in a crowded lot with lots of people walking in close proximity to the cars.... I believe I just hit the park button... then reapplied the brake (which now felt normal) and I haven't had the issue since.... this issue has been discussed in Prius forums at length and there is a very consistent theme to the incidents that Toyota should explore and deal with.

I have a Toyota Prius and it has been recalled about the brakes. I sent it in to have the brakes fixed, but I am still having problems. When ever I start to stop the car and there are bumps in the road the car seems to accelerate or the brakes release. It only happens if there is bumps in the road. The car will not stop when it hits the bumps. What should I do?

Braking issue - 2010 Toyota Prius. We purchased a 2010 Prius last week, asked the dealership if any/all recall work had been completed and were told 'yes.' Yet, I believe that the dealership misrepresented the facts - both my husband and I have experienced temporary loss of braking in our new 2010 Prius while going over rough patches in the road and over speed bumps/traffic calming bumps. We both doubt that the ABS recall work was actually done before we took possession of the car last week, so we're taking it back to the dealership today. I am not afraid to buy a Toyota and understand that other car manufacturers have experienced quality issues resulting in recalls, but I am very upset that we asked about the recall work and still ended up with a car with braking issues. I don't want to drive a potentially unsafe vehicle.

I own a 2010 Prius. I received a recall notice and took it in to the dealer for repair. Nevertheless, even after the alleged repair, problems still happen while braking. Specifically, if I hit a bump or a pothole while braking, the car surges forward. I would say this happens to me multiple times per week.

I have a new 2010 Prius with less than 1K miles. On 4-9-10 while pulling into a parking spot I experienced a simultaneous loss of braking combined with unintended surge of acceleration. My Prius jumped the curb that was perpendicular to the parking slot and stopped as it slammed into a brick building about 8 feet beyond the curb. I utilized my safety connect button to record the time of the accident and had the vehicle towed to the dealer. I contacted Toyota customer experience center and now have a case #. I was told that someone would contact me within 2 business days. I am not at all comforted by this very scary incident. I would just like to have my 2005 Prius back as I never had any problems with it. I am seeing that my problem is not unique based on many similar problems on this NHTSA complaint site.

1. brakes disengaged on two separate occasions while braking to a red light and went over uneven pavement. 2. car is parked in garage. In the morning I went to start the car and upon pushing the start button the car started violating shaking and making a clanking noise. I immediately turned car off as this was not a normal occurrence. I pushed the start button again and car started normally. 3. on 4/1/10 took car to Toyota of orange for recall fix of the brakes. On 4/2 while pulling up to a street from a parking lot the brakes disengaged. The asphalt was very bumpy in the parking lot. I was on a slight decline. The brakes disengaged and car lurched forward. It was worse than the other two times. It was scary. If there was a car in front of me I would have hit them.

Although I took my vehicle in for the recall (2010 Prius) last week, the vehicle repeated the loss of brake/surge issue this morning. I also reported to my Toyota dealer last week about abnormal, sudden braking. When applying normal pressure to the brakes, on several occasions the brakes have locked violently, sending me and my passengers against our seat belts. Toyota claimed that the recall may make that better. It has not. Thirdly, I reported last week to Toyota that the car has on occasion shaken violently and made a loud clanking noise (like a washing machine off balance) upon start up, causing me to jump out F the car for fear of it blowing up. They said they had never heard of this. My co-worker, a fellow 2010 Prius owner, reported the same issue.

I have a 2010 Toyota Prius that was recalled and repaired in March 2010. On April 4, 2010 I was driving the car with my wife and was under normal braking conditions when I pressed the brakes and they acted like they were anti-lock. The pedal skipped and went to the floor. It was so noticeable that my wife asked what just occurred and I told her the brakes failed for a second. I was at about 20-30 miles per hour when this occurred coming up to a stop light. Again the car was taken in for the recall prior to this.

Despite having had the brake recall item fixed on my 2010 Toyota Prius, I continue to experience instances when I depress the brake and the car skids from side to side with a sensation that the end of the car is literally lifting off the ground. This has happened to me multiple times and Toyota has told me that the recall fixed any concerns, so there shouldn't be anything wrong. On one occasion when this happened my vehicle actually bumped into a fixed object, causing damage to the front bumper. I purchased this car based on Toyota's reputation and am now so mistrusting of it that I hesitate to put my family in it. As a consumer I strongly feel that I and all owners of 2010 Prius' should have the right to opt to return our vehicles to Toyota and have the opportunity to select a different new or used vehicle of the same price for what we paid for our cars. The proven concerns about the 2010 Prius should be enough for the NHTSA to put pressure on Toyota to allow for some type of restitution. It is not as simple as just trading in the car at any random dealer because the reputation of these cars has severely lowered the market value. Toyota's errors should not be permitted to have a financial impact on those consumers who purchased their cars. I would be happy to allow NHTSA to test my vehicle for a short period of time if it would help in the research of this problem.

ABS brakes fail to engage when one of the front tires hits pot hole / slippery bumpy surface. The car surges forward during braking before braking resumes. The recall and fix toyoto impimented on my car on 2/15 did not address the issue, it only shortened to lag time (period of exceleration - surge forward). The issue still exists and is still a dangerous safety hazard. I reported this to the dealer in smithtown, NY who contacted Toyota factory and they advised the dealer, who advised me that the car operates as per specifiation. The dealer and the factory did not even look at my car! I demanded a work order which they gave me stating "car to be brought back after Toyota is contacted adn advises dealer on the condition". the next day the dealer called me to say totota advised the car is working as per spec. Toyota refuses to address this issue and the dealer will not look at the car. This is a safety hazzard that I should not have to be subjected to. Please contact me. Thank you doreen gebbia, nesconset,

I purchased my 2010 Prius back in July of 2009 and had problems stopping the car when applying the brake over a bump or a pot hole on the road. The car would accelerate for a second before coming to a full stop. When there was voluntary recall, for me it was mandatory because this was a serious issue because if there would have been a car in front of me, or if this was close to an intersection and pedestrians, who knows what could happen. I took it to the dealership to get the recall. They told me it is some software update. After getting the vehicle serviced, I took it for a test drive and noticed slight improvement in the response when applying the brake pedal. But this morning as I was applying my brake heading towards the intersection to make a turn, I hit a pot hole and the accelerated again and I had to quickly maneuver the vehicle to avoid collision with the car in front of me. Whatever they did with the recall did not resolve the brake problems.
