I have a 2007 toyota prius that is approaching 36,000 miles soon. its brakes stutter when i try to come to a smooth stop. its engine also vibrates excessively as if its misfiring, when idling. the symptoms do not happen all the time, but they happen frequently. i have taken the car to the local dealership several times, but they have not been able to fix the problems permanently. after my most recent visit to the dealer, they claimed they could not replicate the brake stutter symptoms and that the car\'s computer had no record of it misfiring. if you do a google search on the internet about "2007 prius brake stutter problems", it appears to have happened to many other people. please help. i want the problem fixed, or the vehicle replaced. there has been no physical damage nor crashes nor injuries. however, i am concerned that such symptoms detract from the value of the automobile, or at worst may result in an actual crash and injuries later on. the symptoms are a distraction and annoyance while driving. *tr
I own a 2007 prius. i was driving on the interstate when a car in front of me stopped abruptly. when i stepped on the brake, there was a delay before it engaged. to prevent running into the car in front of me, i veered to the left while continuing to step down on the brake with more force. when it engaged, the car was out of control "fish tailing" from side to side. in an emergency situation, there is no room for a delay. this created a very dangerous situation which could have been fatal. i experienced a similar delay while driving in the city, not on a highway. it was the same sensation of the brakes failing. when one is braking in an emergency situation, this is terrifying and not acceptable and not safe... *tr
Whenever i brake when going over a bump, such as a manhole cover, pothole, or cobblestone road, the abs system engages and for a moment the brake does not seem to be working, the car is not slowing. i am worried it could lead to an accident if another car were close in front of me. when my husband mentioned the problem to the toyota dealer, the brakes were checked and we were told there was nothing wrong. however, this continues to happen and the moment without braking is too long for comfort. *tr
I own a 2007 prius that has a brake issue concerning me. when the brakes are engaged and i go over a rough spot or bump, the brakes "fail" for about 1 second and it feels as though the car is propelled forward. i have been told by the dealer on 2 occasions that "it's just the abs brakes kicking in", however i have never had this happen with any other car i have driven. i have not had an accident (yet) but have become extremely cautious when i can identify a spot in the road that might cause trouble. the lack of brakes for even 1 second might mean that i am unable to stop from hitting a car ahead of me if that car stops quickly and the road if rough. *tr
2007 toyota prius---repeatedly on rough pavement, if my wife or i attempt to brake the car, it is as if the car is running away with us in it. i just had the car serviced at our local toyota agency (landers toyota), and was told that our problem was normal. i tell you it is not normal, and has never occurred in any other car i own or have owned. *tr
This is an incident involving the brake stability system of our prius (2007). it did not result in a crash or injury. my wife had been going to different stores and on leaving a store, suddenly the brake system acted very strange. the vsc icon was on and the red parking brake light remained on. my wife could barely drive the car home. we read the instruction book and learned that she should not have driven the car. but this information is buried in a very large instruction manual. the car was towed to our toyota dealer yesterday (march 18th). working on it today, they still have not found the problem. the service advisor is joe and his phone number is 540 382 2981 ext 6326. we thought our experience might provide a clue to the problems that others are encountering with toyota brakes. *tr
I drive a 2007 prius. while going over rough patches, potholes, etc., my car seems to lurch forward and momentarily lose braking control. the vsa light flashes as well. it is definitely worse in the rain, and if i am turning. *tr
Two months ago, i purchased a used 2007 prius and have been experiencing some odd incidents with the brakes. for instance, when i was exiting the freeway last week, i ran over a small pothole and the car lunged forward even though i was braking the whole time. also, when i drive at speeds higher than 60 mph and press on the brake, it always feels like there is a slight delay before the brakes actually take hold. it feels as if the brake pads on the tires are momentarily disconnected (for less than a second). i asked the toyota dealership if the 2007 model has been affected by all of the recent recalls, but they reassured me that my prius is fine. nonetheless, i wanted to report these incidents to the nhtsa in case others are experiencing similar problems. thank you. *tr
This has happened dozens of times, to myself and my wife. we are braking, and whilst braking drive over a pothole or drain. the traction control comes on, and the car disengages the brakes and the car lurches forward. after clearing the pothole, the traction control then disengages, and the brakes re-engage. several times, i have come close to hitting the car in front. conditions: clear, sunny, dry roads. car: toyota prius, year 2007. *tr
When braking while driving over potholes, speed bumps, manhole covers, or any kind of bump in the road, car lurches forward, and brakes do not work at that moment, in addition, the traction warning light flashes telling driver car has lost traction with road. it occurs every single time the brakes are depressed while driving over a bump, pothole, manhole cover, or any kind of bump in the road. have come extremely close to rear-ending an individual in front of me at an intersection because there was a bump as i approached the intersection, and was braking to slow down. have taken to dealer once and told brakes are fine, unable to duplicate problem. taking back again to have service technician ride with us so we can demonstrate problem. *tr
When i drive my 2007 prius to work, i pass by 101 south to 110 south freeway. at that curve, there is a little bump, when i drive about 30 mph at that bumpy spot, i experienced four times lost my breaking system for a second or two. (whenever i loose braking system brake light come on for a second or two) one tine i had nearly miss the car in front. whenever i drive that spot i am slowing down to 20 mph. 2007 prius definitely has braking problems. i am afraid to drive my prius. i need help. *tr
I own a 2007 toyota prius that exhibits exactly the same symptoms with the braking system that has caused the recall in 2010 models. when going over a bump the brakes appear to fail for about 1 or 2 seconds which gives the illusion that the car is lunging forward. this happens everytime i am applying the brakes while driving across bumps or railroad tracks. i reported this to a toyota dealer twice since purchasing the car and was told this is just how prius's are. *tr
Driving on icy road. slowly approached red light. brakes did not work, no pumping or slowing. this occurred twice. able to avoid accident. took to dealer who said brakes checked out ok. why did they fail? *tr
I was braking to slow down and make a turn. when i applied my brakes over the uneven surface, the brakes were working, then let up for a second. this has happened enough that i have changed my driving habits to account for this slippage in brakes. it's not a sliding issue - i can feel the tension in the brake pedal ease up momentarily each time. i'd say this happens at least once per month since i purchased the car new in 2007. *tw
My 2007 prius touring can/does experience braking issues when slowing/braking downhill and coming in contact with a manhole cover, pothole, or other "even" road surface. thought it was the tires, so replaced the original bridgestones for nokians, but the issue still occurs. the "sensation" is you feel like you've lost control of the car momentarily. as a result, i've changed my commute route home and drive much slower (was already driving slower since prius mileage is dependent on mph). on occasions, the speed (on a straight away) set with cruise control will increase by itself ... by a couple mph .... w/o me doing anything or touching anything. so i'm forced to tap brake ........ occurred this weekend with passengers - they said they felt the surge .....
