Car loses braking ablities when going over rough terrain or slippery terrain. The abs initiates but then stops. The abs light can be seen on the dash (normal). This action is very frightening. The stopping distances have left room for error, so no accidents yet.
Traveling at 40 m. P. H. A pickup truck pulled out onto the roadway ahead about 150ft. I depressed the brake and the vehicle slowed quickly at first to roughly 35 m. P. H. When the abs warning light displayed for a brief moment to about 30 m. P. H. After the warning light stopped flashing; 2 flashes, about 1/2 of a second, the pressure was solid and the vehicle slowed minimally. I managed to stop the vehicle in time, but felt that the brake system had failed to properly slow the vehicle. It felt like stopping a train. I feel unsafe in this vehicle under these conditions and have seen a lot of similar incidences reading online. I'm concerned for my the safety of my family and other motorist, and feel that Toyota should take the responsibility to resolve this issue with these vehicles.
I was driving car about 25 miles p h and sandalee the abs lights came up and its was ready hard to stop the car somehow break wasn't working properly.
In the morning I started my car and the abs light and warning lights came on and started beeping. I reversed my car slightly to check the brakes and noticed my brakes were not being responsive. I put the vehicle into park and called the wondries Toyota dealership and told them my brakes were not functioning properly and my abs warning light was on. Despite my having informed them of my brake failure, they told me to bring the car into the dealership. I reversed out of my garage, shifted the car into drive, and proceeded down the hill with caution. I did not press on the accelerator. My car began to accelerate down the hill due to gravity and reached a speed of approximately 15 mph, at which time I pumped the brake pedal but the car would not stop or slow down, and it continued moving down the hill. At the bottom of the hill, after traveling approximately 1/4 of a mile, I turned right into a small street with a slight incline in order to stop the momentum. My car slowed and I put on the emergency brake and put the car into park. I called my brother for help. When he arrived, I turned the car on to show him the flashing abs warning. It flashed for about another 15 seconds before suddenly stopping. My brakes then began functioning again though they felt spongy when I pressed down on it. I turned on my emergency lights and drove slowly to the dealership. I parked the car and turned off the engine. When a representative came by, I turned on the car and she pressed down on the brake to feel them. The abs lights suddenly came on again and she said the brake pressure did not feel right and there was something definitely wrong with my brakes. After it was assessed I was informed I needed a new abs actuator assembly and an accumulator pump for the master cylinder. Total cost was estimated as $4600.
The contact owns a 2005 Toyota Prius. The contact stated that the brake and abs warning lights illuminated. The vehicle was taken to the dealer for diagnosis where unknown repairs were performed however, the failure recurred three days later. The contact stated that the brakes malfunctioned and additional pressure to the brake pedal was needed to stop the vehicle. The manufacturer was notified and no solution was offered. The failure mileage was 92,000. The VIN was not available.
While cruising at 35 mph, experienced sudden onset of high pitch noise along with the red warning light and abs light being illuminated on console. When attempting to brake, noticed that the brake pedal felt very stiff and not depress. Fortunately, there were no cars in front, and was able to gradually stop the vehicle by pressing on the brake as hard as possible. The braking distance felt a lot further than usual. After coming to a stop and waiting a few minutes, stopped and restarted the engine. The high pitch noise stopped once the engine turned off. Once the engine was back on, the brake pedal felt normal again, and while the abs light was no longer illuminated, the red warning light remained on. Took the car immediately to the Toyota dealer where my car is normally serviced, and they indicated there was a fault code c1300 and recommended replacing the skid control ecu (part# 89540-47130). Looks like there is at least one other incident reported on this (odi id# 10320472). This seems to be a major safety hazard due to potential loss of braking power if this component goes out. Request investigation and safety recall as appropriate.
The contact owns a 2004 Toyota Prius. The contact started the vehicle and the abs warning light began to illuminate. The brake pedal traveled to the floor upon application. The contact proceeded to drive, although the vehicle would not stop unless the brake pedal was applied repeatedly. The vehicle was taken to an authorized dealer where they replaced the abs actuator. Two weeks after the repair was performed, the failure recurred. The vehicle was taken back to the dealer who stated the defect could possibly be related to the skid control unit. The vehicle was not repaired. The manufacturer was made aware of the problem and recommended the vehicle be taken back to the dealer for inspection. The approximate failure mileage was 94,000. The VIN was unavailable.

The contact owns a 2010 Toyota Prius. The contact stated that the brakes were applied but the vehicle did not respond or slow down. The abs warning light illuminated and the driver had to use the parking brake to stop. The vehicle was taken to an authorized dealer who replaced the master cylinder. The failure continued. The vehicle was taken back to the dealer where it was scheduled for a second repair. The VIN was unavailable. The current mileage was approximately 100,000 and the failure mileage was 97,000.
I drive a 2005 Toyota Prius. My car has 26,000 miles on it; which is very low mileages. While I was on the highway, my car`s lights on the dashboard starts to flash. The brake system warning light and buzzer comes on along with the abs warning light and the malfunction indicator lamp. I had nowhere to pull aside. After two minutes the warning signs shut off so I kept driving. Five minutes later, all the warning lights come on so I decide to get off the highway to take it to the knoxville Toyota dealer. As I`m exiting the highway, I immediately realized that I had no breaks (when I pressed the brake pedal with my foot it automatically touched the ground)! I remembered that my dad always told me that in case of a brake emergency to pump the paddle until the breaks work. I almost crashed into another car; the exit ramp was very steep. I was going about 50 miles per hr by then; luckily I managed to stop while I kept pumping my breaks. I took it to the dealer right away. They checked my car and replaced: pump assy. Water, super long life c, inverter coolant pump, sliding yoke, reflashed engine and hv ecu and shaft kit. Steeri. I found my case very dangerous and my life was at risk. Not only was my life at risk but as well as other individuals. I would hate for this to happen to someone else! it was scary and I felt like my life might have been over.
Frequently while driving on dry, clear and clean roads, my car braking system will seem to fail and feel like the car is going into a skid. The abs warning light comes on as well - although there is no reason for brake trouble. Seems to be happening more and more frequently lately.
Issue relating to Prius brakes. I have a 2006 Prius and have experienced the brake issue ever since I've owned the car. I don't think it is entirely brakes, because I've also experienced it while accelerating and one of the wheels loses traction. I think it is the traction control system / abs. Anyway, I've learned to cope with it, the dropout is only for less than a second, and there's never been an accident (or even near accident) because of it. This latest event was slowing down for a turn and one of the wheels went over a manhole cover. That wheel locked up and the abs light came on, and the brakes cut out and then back in.

I own a 2007 Toyota Prius and I have noticed that if I am braking and hit a bump or a pothole, that the braking seems to pause and I have to brake harder. Also the abs warning light will sometimes flicker. This has happened on numerous occasions over the past 3 years. Fortunately, I was never in a position to endanger myself or another, but in other circumstances it could have been a problem.
I have a 2006 Toyota Prius and for years I've had the same problem described in the news. At times when I drive over bumpy terrain, the car will lurch forward with sudden acceleration and the abs light will come on. I can re-gain control by hitting the brakes hard and/or pumping the brakes depending on the circumstance. This has happened many times since I bought the car new in January 2006. In these circumstances, my foot was off the gas pedal. I'm not sure if the brakes were being applied or not, but if they were, they were applied lightly. This happens regularly.
When driving on rough road or over rail road crossing and applying brakes brakes fail for split second and abs light flashes nothing done to fix issue.
There is a problem with the Prius abs. If the car transverses ruff terrain during low speed braking, the abs light flashes, the brakes release, causing the vehicle to accelerates. It requires increased pressure to get the vehicle to slow.
I was driving my 2007 Toyota Prius in heavy rush hour traffic and cold, wet snowy conditions this past Friday night. My brakes failed to engage twice. The first time I was going 5-10 mph and stepped on the brake to maintain a safe following distance with the car in front of me, which had stopped. It was as if the car was in neutral and a yellow light started flashing on the dashboard (I think this was the abs system light, but I don't know) and I fortunately coasted to a stop before hitting the car in front of me. There was no skidding or sliding, just a non-response from the brakes. The second time occurred about 10 minutes later and I was again traveling at slow speed and attempted to brake to stay a safe distance from the car ahead. This time I repeatedly pressed hard on the brake and initially there was no engagement and then after approx 5 sec the brakes did engage and I again was able to avoid a fender bender. I drove the car home (white-knuckled) and it has been parked in my driveway over the weekend - we experienced a major snowstorm and I have not been able to drive anywhere. Tomorrow I am going to see if I can get the car towed to a dealership because I don't want to drive it.
I bought a 2009 Toyota Prius in March 2009. On several occasions, while braking over rough roadways, the brakes have seemed to skip (and the abs dashboard light comes on). My wife has also experienced the same issue several times. While we initially thought it was due to the road conditions, after the announcements regarding the brake issue with the 2010 model, I had to report that this issue is also present in my 2009 model.
The contact owns a 2005 Toyota Prius. While driving at speeds of 45 mph, the abs warning light and master warning light indicator illuminated on the warning panel. The driver experienced total brake failure. The vehicle was towed to the dealer for possible repairs. The dealer replaced the battery in an attempt to correct the failure. The vehicle exhibited the same issue again after the repairs were performed. The current mileage is 71,000 and the failure mileage was 67,079. Updated 05/11/10. Updated 06/03/bf updated 06/04/10.
This is for a 2008 Toyota Prius. This problem occurs during normal daily/routine driving, and occurs almost daily. Problem: while braking, if I encounter any non-smooth surfaces (small pot hole, slight gravel, etc) or while braking and turning--the braking pressure/force momentarily releases for about a 1/2 second ,and is immediately followed by a flashing abs light. When this occurs, the car also momentarily lunges forward due to having no braking force. On 4 occasions I almost ended up into cross traffic at an intersection. This has occurred since I first owned the car back in July 2009 and is not a recent development. This same problem occurred today during my commute to work on wintry mx weather roads, but I did not have any near collisions. No repairs or work has been performed on my car to fix this problem. I assumed this problem was inherent to hybrids, but in light of recent Prius braking problems on the news, I felt it was my duty to report that my 2008 Prius does have a braking issue.
I am having issues with my 2008 Toyota Prius brakes. When I apply pressure to the brakes (gentle- not sudden) there is an instant when the car jerks forward and seems to speed up. The abs sensor light comes on for a second or two, then goes off and the normal braking resumes. This also happened to me with my 2006 highlander hybrid (of which I leased from 9/06-4/08). When I brought it to my dealers attention, what was going on, they said that it was completely normal. It did not seem normal to me. In fact, I have a neighbor who also has a highlander hybrid who attributed a recent fender bender to this very brake/jerking issue. This happens almost on a daily basis (every 2 days would be more like it), particularly when I drive on the bumpy country dirt roads around where I live. I typically drive slow (10-15 mph) on the dirt roads because I don't want to damage/jossle the parts in car 'loose', so 'high' speed would not play a role in why my abs light comes on and the car jumps forward. The issue has not been corrected by my dealer, though I have brought it to their attention with both cars. As I mentioned earlier, they said it was 'normal'. Fortunately this has not caused an accident but I typically drive very conservatively and am very aware of what this car does - brake wise, so I tend to brake early, if possible.
This incident involves my 2007 Toyota Prius hybrid that I have owned for almost a year. As I was driving approximately 40 mph and put my foot on the brake as I approached a red light, the red brake warning came on the dash as did the abs warning light. My foot went all the way to the floor and I had no brakes. Luckily I had a right turning lane that I could veer into and not hit the stopped vehicles in front of me. As I continued to push the brake to the floor and maneuver the vehicle out of traffic, it seemed to catch a little and I was able to slow the vehicle eventually to a stop. I put the vehicle in park as it was still running, and pulled out the owner's manual. The manual specifically stated that if these two warning lights came on at the same time, you were to "stop immediately and contact your Toyota dealership". This is exactly what I did. I had the vehicle towed into their facility that evening. The next day I was interrogated by the mechanic after a diagnostic report was done on my car. He wanted to know when I let the car run out of gas. I have never let my car run out of gas, and in fact that just filled the take the day before this incident occurred. The mechanic couldn't tell me what was wrong and contacted Toyota's corporate office. Two days later, I was advised that the reason the brakes didn't work was because I "let the car run out of gas "and this caused the engine to shut off. I argued that the car had never run out of gas and the engine didn't shut off, the brakes went out. The service manager pulled out the diagnostic test showing that "at some point" the car had run out of gas----this test doesn't give a date of when this may have happened. I advised the service manager that the car had 223 miles on it when I purchased it-- this test result could have happened when the car was still at the dealership, not in my possession. The service manager advised me that his "hands were tied" and that Toyota had made their decision.
I own a 2008 Prius. When braking on an uneven surface, the brakes seem to momentarily fail and the abs light blinks on the dashboard. It makes me feel as though there is a defect in the braking system. This happens regularly. Incident date is actually date of purchase of the car.
The contact owns a 2005 Toyota Prius. The contact stated that the vehicle began making unfamiliar noises while parked. While driving 30 mph, the noise continued in intervals. The service brake and the abs warning lights illuminated on the instrument panel. The vehicle was taken to the dealer and they stated that the brake actuator assembly (part number 4450047090) needed to be replaced at an estimated cost of $2,600. The year before, the brake actuator assembly was replaced under warranty by an authorized Toyota dealer. The manufacturer confirmed that the part was previously replaced in may of 2007. The failure mileage was 18,799 and current mileage is 32,016. Updated 10-07-08 the tire showed unusual wear patterns. The vehicle pulled to the right. Updated 10/07/08.
Lose brakes momentarily when they are applied on an uneven surface such as railroad tracks, pot holes etc. Abs light flashes then braking returns as long as brake pedal stays depressed. This has occurred from the time I bought my car and I thought it was just a function of abs brakes until I saw the description of the 2010 Prius recall.
2004 Prius hybrid abs and other dash lights illuminated . Problem was fixed per mechanic, 15 days later lights illuminated.
