I was in a parking structure going approximately 15 MPH when I removed my foot from the accelerator to press the brake. Before I could get my foot to the brake, the car quickly accelerated. It took at least two attempts at pushing the brake peddle before the car came to a stop. And, to be honest, the guardrail the car hit helped actually stop the vehicle. It was totally unexpected and extremely scary. In hindsight, I should have suspected that there may be a problem when I noticed that sometimes when applying the brakes to come to a stop there would be a feeling of the brakes slipping and the car lurching forward a bit. The dealership had the car towed in to get checked out, and I have been told that they will notify toyota. In the meantime I am concerned about the safety of this car!

2010 toyota prius. Consumer states problem with the ABS system *tgw the consumer stated the first time he went to the dealer for the ABS problem, they were unable to find a defect. One month later, the consumer returned to the dealer and they reprogrammed the ABS and the brakes worked fine for about one week. Soon, the brakes began slipping again and ultimately, the consumer crashed into another vehicle. The consumer stated it seemed the brakes would fail when he applied the brake, released his foot and then braked again.

My 2010 toyota prius has always had problems braking over bumpy roads. At certain speeds firm braking over bumps causes the wheels to feel like they are slipping. Toyota recalled the vehicle, and performed software upgrades that I feel did nothing to improve the situation. I recently brought the car back to be serviced and mentioned that it was still slipping over bumps but they claimed that they could not replicate the problem. This is not one specific incidence but multiple instances.

I was going down a hill (approx 20mph) in my subdivision (north on harter farms rd) when I saw a car pulling out onto the road from his yard. I applied the brakes hard for about 100yds before attempting to turn into palimino dr to avoid a collision. I did not make the turn and hit a stop sign and then the guard rail at approx 5mph. There was about 1-2" of snow on the road and I had driven up the same hill from a stop without slipping a tire just 15 min prior. I never felt any pulsation from the ABS during the attempt to stop. Afterwards when I got home I attempted to stop hard (to test the brakes) on level ground and again never felt the pulsation from the ABS system. There was braking but I felt it was greatly reduced. I have not returned the car to toyota for their recall yet. If you wish to examine the car you may. I am sure you can duplicate the results.

Re: 2010 toyota prius iv; on february 27, 2010, I visited the toyota santa monica service department to have the ABS software update installed. Since purchasing my vehicle in september 2009, up until the date of the software update, I experienced the inconsistent feel of the brakes usually once per week. However, since the software update, in the first week alone, the inconsistent feel occurred seven times, with the most alarming incident occurring during my morning drive to work on friday, march 5th. I was driving on pico boulevard just past avenue of the stars, gently tapping on my brakes down the hill for a stop, when the car briefly accelerated and almost rear-ended the vehicle in front of me. Additionally, I experienced the brief acceleration twice while braking for pedestrians at crosswalks last week. Now, I am experiencing the slipping sensation with the brakes about 2 - 3 times per week. I have calling toyota toll-free customer service nineteen times, but each time received an automated message stating that the company was experiencing high call volume and would be unable to answer my call. I sent two faxes on march 6th, asking the company to arrange a second service appointment to repair the brakes. I have yet to receive any type of response from the company. Today, on march 20th, I called toyota santa monica to describe the problem and request a second service appointment. While driving during my lunch break today, I again had the brakes slip on me. I spoke with a service supervisor at toyota santa monica at 500 pm today to ask for a second appointment. He decided to insult my intelligence and tell me that what I was experiencing is a normal feel of the ABS brakes. This is unacceptable! I want the car repaired. If toyota cannot prevent this inconsistent feel and slipping sensation in my brakes, then I was my purchase contract to be completely dissolved. I will not continue to finance a lemon and have toyota lie to me about its safety.

I have a 2010 toyota prius that has had the software update recall performed. Since having the recall done, the brakes on the car seem to work even worse than before. It still occasionally feels as though the brakes are slipping while going over a bump, and the brakes also do not seem to work as well under normal operation.

I own a 2010 toyota prius. I have experienced some dangerous occurrences while driving. 1) occasional loss of traction (for a second+-). Problem has occurred aug, 2009 - present. Usually occurs when heading downhill or when driving over a manhole or drainage cover. Car feels as if slipping or airborne for a moment.. 2) frequently immediately after starting car, at slow speeds of only 0-5 MPH, car is jerky each time brake is applied. Problem has occurred aug, 2009 - present. Passengers are actually jerked, as if driver was applying brakes too suddenly. Even with great attempt to stop smoothly and gradually, it is impossible. Brakes grab and jerk. This occurs both in reverse and forward, yet not every time engine is started. It lasts for only a minute or so, but makes maneuvering while parking or entering traffic unsafe, as well as making driver look inept. I cannot figure out if this is a braking or acceleration problem. When calling a toyota dealer (nov, 2009), I was told they had no similar reports of these problems and offered no solution. My concern has increased with the recent recalls when calling a toyota dealer previously, I was told they had no similar reports of these problems. My concern has increased with the recent recalls.

Driving on slippery roads, but not unpassable, my 2010 prius braking system failed to provide any assistance in prevention of slipping into a parked vehicle in my lane, resulting in 2900+ dollars of damage, plus, since the body shop was unable to properly inspect the damage without taking the car apart. I was found at fault for this accident, for which I fear my insurance rates will rise. I am a safe driver. Never having had an accident before. I new the car was not responding to the brake pedal as it should, and that was before this recall ever came to light. The accident happened on jan. 22, 2010.

I was driving my 2010 prius approximately 20 MPH on an icy road. Because it was icy, I started braking very early before coming to a stop sign. There was no response from the brakes at all. I blew through the stop sign out onto a 40 MPH road. I was only able to avoid a collision by steering away from cars. I applied the brakes the entire time, which was several seconds and the brakes never engaged. The next time I used the brakes, they worked. Initially I thought that the reason the car did not slow down was because it did not have any traction due to the icy conditions. But after thinking about it, I did have traction because I was able to steer quite well and suddenly change directions without any slipping at all. This did not make sense to me until I read about the braking problems. My husband has experienced the car lurching forward when applying the brakes on a slippery or uneven surface many times. He applies the brake and the car lurches forward before the brakes engage.

Since purchase in october 2009, I have experienced occasional problems with the brakes on my 2010 toyota prius. Sporadically, when I apply the brakes to slow down going down a slight incline or stopping at lights or intersection, I feel a momentary lag before the brakes actually function. The lag is noticeable and similar to feeling airborne or slipping causing me to frantically push down harder on the brake pedal than usual. This has recurred perhaps 10 different times I also had one incident when the brake seemed to lock when the gear was in reverse and I was beginning to back out of a parking space. Please note the date of incident and MPH is only an estimate.
