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.
2010 Toyota Prius brakes complaints
Page 45 of 66: complaints 1,301 to 1,330 of 1,945, newest first, as owners wrote them.
The brakes in my 2010 toyota prius do not operate properly. I have had the car 3 months with 1847 miles. Over this time I must increasingly press the brake pedal closer to the floor to stop the car. Today in dry weather, I nearly hit the car almost 50 yards in front of me when it stopped and although I pressed the pedal firmly it took a very long time for the brakes to grab.
I was driving my 2010 toyota prius down the road here in berkeley, ca, and applied the brakes as I was hitting a bump in the road. The brakes did not work. I thereafter lifted my foot off the brake and hit them again, at which point the brakes worked correctly.
Tl*the contact owns a 2010 toyota prius. While driving 15 MPH and engaging the brake pedal the vehicle failed to stop immediately. Occasionally, the vehicle also responded as if it were hydroplaning on normal road conditions and within moments, the brakes would reset. The dealer stated that the vehicle was equipped with an ABS. The failure was a normal occurrence for the vehicle. There were no recalls. The VIN was unavailable. The failure mileage was 7 and the current mileage was 3500.
I want to report a momentary brake failure of 2010 prius over uneven roads 2 months ago. I didn't report it earlier because I didn't know if it was a one-off or systematic issue. Two months ago, I was driving a newly owned prius with hardly 4000 miles on it over a stretch of rt. 93 from andover to boston. I was traveling at about 65 - 70 MPH on the left fastest lane. I cam across a bumpy patch, probably the road was being repaired, and it was not late for me to slow down as I didn't expect such unevenness on a major highway. I stepped on the brake while the car was being tossed up and down by the bumps and I immediately felt that the car lost braking. Luckily, there was no car ahead of me and the braking did recover after the car settled down. I owned 4 toyota's from SUV to the hybrid and prius is the only one that has this problem. I just want to support other people's complaints about this car. I must say that the braking did recover quickly that a collision was not likely unless someone drive the car very fast on an uneven road that is also crowded. However, a car should not behave like this under any conditions.
Toyota prius 4th generation purchased one month ago. Surges forward with brake depressed when going over potholes.
I have a 2010 prius that "lurches" when I brake. This only happens every once and a while. I took it to the toyota dealership, they looked it over and said it was fine. To say the least I continue to be very concerned.
On my prius 2010 (that I bought in july 2009) I noticed that when I hit a pothole, and had the brakes pressed; the car quickly accelerated for a split second. This has happened twice.
Prius 2010 slow braking. I thought it was just me but now I found out the braking is rather slow and a lot of others feel the same way. I have to adjust my braking when I switch cars with my wife and have to extra careful when I switch back to prius.
Tl*the contact owns a 2010 toyota prius. While driving 15 MPH in snowy conditions the contact applied the brake pedal to stop the vehicle and it failed to stop and proceeded through the intersection and crashed into a pole. No one was injured during the crash. The contact had the vehicle towed to a dealer to repair the front end. The contact stated that the braking system failed and caused the vehicle to crash. The failure mileage was 8,800.
2010 toyota prius, package 5 have owned for 6 months or so. When attempting to brake and go over pot holes or irregular road, the brakes disengage and the car continues forward for a longer distance than desired. This has not resulted in an accident but a concern. Has occurred on several occasions since taken ownership in september.
I drove over a bump while braking and it felt like the car was sliding on ice. It felt like there were no brakes.
2010 prius feels like brakes not working bumpy or rough road, also brakes grab real bad when backing up some times. Nothing has been done to fix it.
Tl*the contact owns a 2010 toyota prius. The contact stated that while driving 20 MPH while driving over pothole with his foot on the brake pedal when the vehicle accelerated on it own. This failure occurred 5 times and has continued to occur every two weeks. The dealer confirmed that the ABS system caused the failure to occur. No repairs were made to the vehicle. The vehicle identification number was unavailable. The failure mileage was 200 and the current mileage was 900.
Tl*the contact owns a 2010 toyota prius. She stated that while applying the brakes at any speed more than 5 MPH and over a pothole the vehicle responded as if the brakes had failed and it attempted to accelerate. Within seconds, the brakes would reset and function normally. The manufacturer nor the dealer were notified. There were no related recalls. The failure and current mileages were 8,400.
I bought a 2010 toyota prius in august 2009. After hearing on the radio and tv this week about other buyers experiencing the same braking issue I have been occasionally experiencing, I decided to let you know it's happening to me too. Namely, there is a moment when I am braking at a speed of about 15-25 MPH, in preparation to slow down for a right turn at one particular intersection--it has a large pothole. If I roll over the pothole with my front right tire, the car seems to speed up for a few seconds--instead of slowing down--and there is nothing that applying more brake pressure can do. Sometimes I've noticed this kind of problem when trying to slow down on a patch of black ice, but that seems typical of the difficulty of braking on black ice. The pothole issue happens invariably at that particular pothole, so I have had to swerve to avoid rolling over it. There are other potholes that I've noticed can cause me this problem, but none with such frequency as that. The ground is level there, so it's not a downhill problem.
Regarding my 2010 toyota prius: brakes did not engage. It was raining; I was slowing to make a right turn into a parking lot and merged into the turn lane, applied the brakes just prior to driving over a drainage grate, and car's brakes did not respond. I released my foot from the brake pedal and then re-engaged it, whereas the brakes responded. Incidents very similar to this happened two prior times when backing out of my driveway (not raining). The brake warning light also goes on unexpectedly while idling at a traffic light or when coasting to a stop (not stopping suddenly). When this happens, I have to place the car into park and then back into drive. I inquired about these issues with the toyota dealer and have been advised that they have had no complaints of this nature with their 2010 priuses.
My 2010 prius which was purchased in august of 2009 on several occasions when braking on rough surface or pothole slips momentarily.
I have a 2010 prius and had a 2005 prius with all the safety features. When I had the 2005 prius, I noticed on some roads that during braking, the brakes would release then reengage, giving the sensation that the car is accelerating. This happens when the road has a series of dips (washboard). The first couple times this happened, it was rather frightening because the car in front of me had stopped, and I felt as if I were accelerating. This is a reproducible event that occurs at a known location that I simply avoid. The road in this particular area is also down slope, which lends to the acceleration feeling. I have driven my 2010 prius over this same area with very much the same result. My initial assessment was that the traction control took over to regain traction, however I would not thing this is acceptable. The toyota dealership said this is normal behavior and is not a problem. Please feel free to contact me and I can describe better the conditions for this very reproducible event.
When trying to brake on ice, the car jerks forward. It happened several times before jan. 28th, as well. Today (feb. 04, 2010) ... Braking on bumpy road with slight sink hole before railroad tracks and it jerked forward ... No train on the track and no car in front of me, so I was fortunate not to have a serious accident with my grandson in the car. I have informed boulder toyota.
I've been monitoring the toyota recall news because I have experienced similar braking issues with my new 2010 prius. The best way I can describe it is as if the braking system "hiccups" when the brake is applied while traveling over an uneven road surface. As this was a new vehicle type that I had never driven before I thought it was inherent.
Re: 2010 prius braking issues beginning within the first 500 miles of owning vehicle. When first start up vehicle brakes are overly sensitive, making it impossible to stop the car smoothly. I have been able to correct the problem by shutting off the engine and restarting the car. This problem occurs randomly and has occurred twice within the last week. I have also had two times where the car has had an incredible surge forward, so strong that my head was thrown back into the head rest. The surge has been momentary and has the feeling like going up a steep incline on a roller coaster when it first accelerates. Because these events were such a surprise and so short in duration I cannot recall the conditions (whether I was braking, coasting, or on the gas pedal) but I do know I was going at a slow speed. I have had two occurrences of this surge both within weeks of each other in the fall of last year. I took my car into the dealer regarding both of the above issues in the fall of last year, but they could not get the car create either of the above problems. At that time I asked if they had any similar complaints and they said they had heard of no other such complaints. When the car was taken in to the dealer for routine service in november my husband again asked about the oversensitive braking issue and again no problem was found or solution provided. The oversensitive brake and the surge create physically and emotionally uncomfortable conditions. No damage has occurred because of these problems. I have driven the car with under these conditions figuring until there are complaints it would be hard to recreate these problems at the shop. When I first took my car in to address these issues I told the dealer it felt like it was a computer glitch or electronic problem rather than mechanical. And asked it might show up on the cars computer diagnosis system.
2010 prius: brakes had momentary failure on a snow-covered speed bump. Vehicle speed was about 10 MPH. This was the first of several incidents.
Toyota prius 2010: driving over sewer grate while braking and car loses momentary grip and slides over surface without slowing down, even though braking. Has happened several times on the same location / sewer grate.
At 10mph on the freeway, my 2010 prius hesitated to brake properly and as a result my left fender made contact with the vehicle in front of me. As result, my insurance increased, I had to pay $500 deductible to repair my bumper. The back brakes have squeaked going in reverse since purchase in november 2009.
Tl*the contact owns a 2010 toyota prius. While driving 25 MPH over uneven pavement the vehicle became difficult stop while engaging the brake pedal. The vehicle also accelerated intermittently. The contact has informed a local dealer about the failure who stated that toyota has not issued a recall. The contact is concerned that the brake failure could potentially cause a crash to occur. The VIN was not available. The failure mileage 8,000.
With our 2010 toyota prius, my wife had an accident where the vehicle slid into a snow bank within 1 block of our home. Just prior to this, I noticed that the vehicle's anti-lock brake did not seem to function properly. I used to work for general motors in michigan and know the sound that comes from working anti-lock brakes. The anti-lock brakes used to work earlier in 2009...I had to stop on a wet paint stripe and the anti-locks made the distinctive ratcheting sound. In december 2009, that sound and the loss of braking traction was evident. Not until I see that there is news in the media recently about the prius did I think to lodge a complaint. This accident caused me (and my insurer) $1,024 in damage to our front bumper.
We have been experiencing, intermittently, the exact problem described in recent news accounts about the momentary failure of anti-lock brakes on the 2010 toyota prius. When braking on a rough or slick surface, such as thermoplastic lane or crosswalk markings, the car feels like it's surging forward. We believe it is not so much an actual surging as it is the momentary absence of loss of braking, but it feels like the car is a bit out of control, and potentially dangerous. We have experienced this momentary brake failure on perhaps a couple dozen occasions. Fortunately, none of these incidents have resulted in a crash. We contacted the dealership to let them know that we had been experiencing the same issue described in news reports, and were told that they have not yet received instructions from toyota about a recall or potential fix.
When braking at lower speeds and traveling over a transition (manhole cover, pavement break), the car will act as though the brakes lose grip for a second, then regain stopping power. I haven't hit anything, but it's been unsettling.
