Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

1. event: Normal city driving (I.e., car in drive and cruise control off) 2. the failure: Press on brake and feel softness instead of firmness; must press much harder on brake than typically required to bring car to stop in same distance. Failure occurs sporadically during course of regular driving. Have not associated failure with traveling over rough surfaces. 3. contacted Toyota dealer and was told that we would receive letter in mail instructing us on what to do, because no correction has been developed yet for this problem in existing cars.

I suffered a temporary loss of braking while approaching a toll booth on the New Jersey garden state parkway. The loss occured immediately after hitting a large bump as I was slowing to pay the toll. Soon after braking returned and I was able to continue slowing and did not strike anything.

I have a 2010 Prius III that was purchased on Dec 23, 2009. I experienced a momentary loss (approx 0.5-1 sec) of braking power when I was driving over a road with some bumps. Essentially, the brakes completely cut out, but came back while I was holding back the brake pedal. My mileage at the time was approx 4000 miles. So far, this has not repeated. Another issue is inconsistent braking. Holding the brake pedal down with constant force (my judgment) will cause the car to slow abruptly while at low speeds(<10 mph). This is a very different feeling from the regenerative braking portion (feels like little/no braking at all) and braking at higher speeds (>10 mph).

2010 Toyota Prius loses brake response completely after hitting any medium sized or larger bump. Happens at least twice a week and has resulted in sliding and hitting a curb once. Car is unsafe to drive. Took car to Toyota dealer and was told "there is no fix for this issue at this time" I was given the Toyota customer experience phone number and when I called I was greeted with a recorded voice saying "we cannot take your call at this time" "if you need to speak to a representative call back later" and then hung up on.

Driving a 2010 Prius coming to a stoplight. Went over a raised portion of road resulting in a very noticeable bump. Car seemed to lurch forward and braking didn't seem to work for a short time. Thought I was going to go through the red light into cross traffic but brakes took hold and I was able to stop.

My wife's 2010 Prius occasionally surges forward when the brakes are applied. This typically occurs when driving down hill and over bumps. It happens about 1 time per 14 days. The surge is only for a split second. Control of the car has not been lost yet. Nothing has been done to fix the problem

Brakes on 2010 Toyota Prius fail when the vehicle encounters a rough road surface when braking.(four incidents) I suspect many of these complaints are going unreported because dealer service departments are telling customers the vehicles are braking as designed.

I have on at least 4 occasions experienced the braking issue (that is being investigated) on my 2010 Prius. It happens when I go over railroad tracks, or hit a pothole. Please add my complaint to the others that report similar problems.

The brakes on my 2010 Toyota Prius at times do not engage immediately. It may be necessary at those times to depress the brake pedal by 1/3rd before braking begins. There is a similar delay when braking is used to turn off cruise control. Neither of these have caused an accident, but in both cases there is some risk.

I have experience a problem with my 2010 Prius, while turning right on to another street traveling around 20 mph, I press on the brakes to down slightly when suddenly the car accelerated very fast, I pressed on brake harder and it stop this acceleration. Later I had 2 problems at the same intersection, # 1: I turned right into the street to my right and I noticed my brakes hesitated for about 1 or 2 seconds, I then continued without a problem. # 2: I turned right at the same intersection with the brakes on to slow me down, when the car seemed to accelerate slightly without my foot on the gas pedal. There are many small pot holes at the intersection.

My 2010 Toyota Prius brakes fail briefly (1-2 seconds) when braking at low speeds and driving over a pothole, speed bump, or manhole, especially on wet roads. Brakes resume appropriately when brake pedal is pressed again or pressed in harder. I first noticed this during the first month I owned the car (August 2009). This happens to me about once every two weeks. Nothing so far has been done to correct the problem.

2010 Toyota Prius braking problem. Going down steep long hill, with rough surface, we encounter this problem 1 or 2 times a week, repeatedly. It feels like we are "flying" down the hill briefly, out of control, while in fact, we are going approximately 15 miles per hour and are applying the brake in the same manner as always. This is very scary, as the hill has a huge deep ravine on one side, and a high cliff on the other side, and a cliff off a beach into the salt water at the bottom of the hill. The road is very narrow, with 2 vehicles going up and down only able to pass at selected positions, otherwise, one lane traffic. Please demand that Toyota recall this vehicle, and replace the software that controls the braking system. I understand from the news that they have this fix in place on new cars since last month. Please recall this vehicle asap! my vehicle number is [xxx] production date 6/09. Thank you. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I was driving down a hill that has a slightly uneven surface and was a bit icy and when applying the brake in my Prius, my car sped up slightly when it hit the uneven surface and seemingly jumped faster before the brakes kicked in and brought my car to a stop. This has happened twice on different roads, both of the road surfaces being slightly uneven. Nothing has been done to correct this problem, when I called Toyota they told me that there was nothing they could do.

Dear sir, I would like to bring a problem to your attention. I purchased a 2010 Toyota Prius, VIN# [xxx], in June 2009. The problem is not the brake problem being described in the predicted recall. My problem is as follows: When the vehicle is driven and then parked (shut down ) and started again, the brakes will lock up at the slightest pressure on the brake pedal. When starting out of a parking spot, either forward or backward, the slightest touch of the brake pedal will lock the brakes and stand the car on it's nose. I have found that if the problem occurs, I can either stop the vehicle ( shut off with the start button ) or hold down hard on the pedal for 10 to 20 seconds, the brakes perform normally. I returned the vehicle to the dealer in August 2009 for an oil change and reported the problem, but the service department dismissed the complaint as 'could not duplicate the complaint' even though I explained that it did not occur every time. I can not connect the problem with any particular situation. It can occur with normal driving or in eco mode. I feel it is an annoyance more than anything else, but could pose a problem in certain circumstances. I will gladly answer any questions you may have regarding this problem.

Purchased 2010 Prius V apporx. Mid-June. Drving in first wk of ownership, observed break problem. Vehcile had approx. 50 miles on. Drining 25-30 mph on straight, smooth, blacktop road on a sunny, nice day. A car backed out of a 45 deg parking spot without warning, I had to slamp on breaks at the same time the gas/electric motors were switching. The break pedal lost feeling that it had pressure until I pushed the break pedal another 2 inches more to feel pressure and that the breaks were grabbing. I did not report this in June, due to I thought I was imagining things due to the emergency stop took my attention to some degree. I was a service manager for Chrysler years ago, so I am very familiar with vehcile mechanical systems and I have purchsed approximately 25 new vehciles in my lifetime.

Regarding our 2010 Toyota Prius purchased in August of 2009, we have experienced braking issues in two instances: 1) when braking for a stop sign and hit a bump in the road the car surges forward 2) when braking on icy surface the brakes seem to lock up causing control problems. In speaking with the dealer they indicated that they had know knowledge of a fix to the issue and after speaking with Toyota they gave us a rental that was supposed to have come out of production after the software was fixed to correct the brake problems. While driving the rental we experienced the same issue while braking over a bump in the road.

Experienced lack of braking when my 2010 Prius was going over bumpy terrain. I was pressing on the brake as I was approaching an intersection, and no braking was occurring until the car reached smooth ground again. Instead it felt like I was skidding, and the brake pedal just vibrated back at me. I can confirm that the problem being reported in the news media in Japan, is in fact, a real problem. When I heard about it on the news, I realized, hey, I experienced that. I would encourage a recall. It is a legitimate problem that does indeed sometimes occur in the situation I described. It is scary.

Toyota Prius 2010. My car has a braking problem, the rear wheels seem like they are not holding. If you hit a bump and the wheels are in the air =then grabs the ground. I thought that I was hitting pot holes causing this but there was none to see.

Regarding my 2010 Toyota Prius I purchased in November 2009: Sometimes on icy, snowy streets there has been a delay after I press the brake pedal before the anti-lock brakes activate. The car has just skidded at first. This delay in braking has also occurred when I have applied the brakes on bumpy surfaces. Total incidents have been five--three on ice, two on bumpy surfaces.
