Prius (2004-09) :: Brakes Jerky And Unreliable - Initially Does Not Respond When Applied
Jul 23, 2014
2004 Prius (123,000 miles). For the second time in a month, while driving, the brakes have suddenly gone funny (for lack of a better word). When I first apply the brakes to slow the car, it initially does not respond, then, as I continue to gradually depress the brake pedal, the car will begin to jerk as if I am slamming on the brakes repeatedly.
Just before this symptom begins, the brake system warning lights and master warning light come on.
The first time this happened, I took it to a shop (not Toyota-specific) and they found that my floor mat had slid forward and folded and was under the brake pedal touching the wires. When they removed the floor mat, the problem went away. I threw out the floor mat and have been driving without one.
Today, the same thing happened again, with nothing obstructing the brake pedal.

Just had a couple questions, The first one is in regards to the brakes on my '09. I've read that the brakes themselves don't actually kick in until you are going 7 mph or less. Anyways, when I am coming to a stop it is not necessarily smooth. I try my best to apply even pressure to the brake, but I basically come to a jerky stop. Is this common in a Prius? I bought my car certified pre-owned last month and I know the brakes were one of the checklist items.

I have a question: when physical brakes applied (at the end of the slight braking, or when speed is small, or when gasoline engine starts on parking car, or when i apply brakes on parking) i hear light "pssst" sound. It is like sound from back door stay assembly, when i open back door, or like suspension shock adsorber works. My local service bleed the brake fluid, but it doesn't work. When we bleeding rear brakes (left and right) and opens bleeding plug, that noise sounds continuously until we close bleeding plug. And there is no air in old brake fluid... Technician says, that sound is normal, but i also have Toyoyta Prius 20 and there is no noise while pressing brake pedal... I just want to ask: is that sound normal for Prius 30 or not?

My wife told me she was hearing a squeaking sound coming from the front end of our 2006 Prius (90,000 miles) along with a noise when she applied the brakes.

My 2005 Toyota Prius gave me confidence. Here's what happened:
I was driving on the Interstate with the cruise control set at 70 mph. Seeing traffic stopped ahead, I applied the brakes for a moment to slow, then released the brake to coast. Much to my surprise, the cruise control was still engaged and the car accelerated. I applied the brakes again, manually turned off the cruise control, then was able to coast. I drove for another half-hour without incident until the following afternoon when I drove again, experiencing a much more serious problem.
I had just turned left, and was straightening the wheels when I heard, and felt, a loud "snap" in the steering wheel, immediately upon which I knew the steering wheel was disconnected and I could no longer steer the car. Very, very fortunately, and only because I was already nearly stopped, I was able to stop the vehicle without incident.
However, I immediately recognized that, had this happened in almost any other scenario than being nearly parked, the outcome would have been markedly different. The steering wheel is completely loose, not controlling anything, and all the many steering wheel controls are equally disconnected, including the driver's air bag (SRS), something that I would have needed, but wouldn't have worked, had I crashed into oncoming traffic or an Interstate median.

I have a 2008 Prius basic model bought second hand. There are two issues since I have bought the car; first it will roll back or forward when the brake applied, this happens on any uphill or downhill. I brought the car to Toyota service centre, they did a brake test, the test passed. but this doesn't resolve this issue. It just very weird. during driving, all brake works ok, but parking the car, if not in even service, it starts to roll.
Second, recently I hear there's a crack sound when apply the brake during low speed, especially during the stop/start traffic, and I notice mostly happens when the electrical motor in running. So when brake, the crack, like the spark comes from somewhere like battery. While brake to slow down from high speed, seems no sound. So I suspect it was from the battery or electric motor.

My dad purchased a new 2013 Nissan Frontier 4wd in June 2013. On occasion he has issues with acceleration in that he steps on the gas to go (from a full stop), or steps on the gas to speed up (and pass) and the accelerator does not respond. After anywhere from 3-10 seconds it will lurch forward and go. This is an inconsistent/random occurrence. He has taken it to 2 dealerships and they can't seem to find anything wrong.

Our gen 1 has developed a (currently minor) noise issue when braking. I'd like to sort it out before it becomes serious.
The brakes are still strong, and the regenerative system appears to be working. When the brakes are applied (even gently) there is a pulsing raspy sound, seems like it is coming from the front, driver's side. It is more rapid at higher speeds, and louder during rapid deceleration. I guess I'd call it 'grinding', although this is much less unpleasant than the classic 'grinding brakes' I've heard on other cars.
In any other car I would figure a warped rotor or worn out brake pad. But I had imagined that the regenerative system handled light braking, and conventional brakes took over beyond a certain threshold. Now I'm hoping they work in tandem, even on gentle braking and this is just a boring, simple pad issue.

I've had my 2011 Prius II for two months, and I love it. One little thing bugs me, however. I have noticed that sometimes when I apply the brakes, the car lurches forward a little bit. But I keep the brake pedal on, and the car does stop. Is there something wrong with my brakes, or is this something that has to do with the regenerative braking?

I have a 2012 Prius with 15000 miles on it. In the year I have had it, I have had this problem a few times. On rare occasions while I am braking the car seems to lurch forward. In particular I have noticed it while braking and hitting a bump. The problem is that when this happens the car seems to jump forward while the brakes are being applied. My foot is on the brake when it happens, but I am not braking suddenly. That rules out any anti-lock braking. I have had the dealer look at it but since it didn't happen on their test drive they couldn't figure anything out. They did open a case on it in case anything comes up.

2005 Lexus RX330. 98K miles. 2 year intermittent problem. When apply brakes the front end shimmies until car completely stopped then go again & all is well until at some future time it happens again. Dealer checked twice & private repair checked also. Nothing found. Tires re-balanced & rotated several times. Newer tires with no issues. This is an INTERMITTENT problem. The rotors have been, new pads & spring installed.

Coming to a left turn signal I was anticipating it turning red on me, and I drove into the turn lane briskly 30mph and then applied brakes as I made a u-turn. It sounded like a cross between dragging the front air dam and metal on metal brake grinding as I made the turn. Stopped immediately and did not scrap the air dam and all front end components checked out, okay. Car is driving just fine now, has only done this once.

When I gently apply the brakes at slower speeds there is a single "click" noise. This happens every time. I took it to the dealer. They said it was normal. I am just trying to find out if indeed it is. Do other people get this click when they apply the brakes.

So, just overnight, suddenly the car doesn't respond to my key fob. When I press the button on the fob the little red light lights up, so the battery works. I open the car by using the old school physical key and get in. The car refuses to start up until I try to put the fob in its slot, and then it starts like normal. What could this be? I tried checking other threads, but they were all about the fob being out of battery or broken, which doesn't seem to be the case here, as I tried both my two fobs and neither work.

Why my 2010 Prius has 3 times now failed to stop when brakes were applied on a steep downhill in slight rain? Happened a year apart with no slick road and with tires both new and old. I pull up to a stop sign on a grade, apply brakes, the car slows, then there are metallic noises and the car glides 3-4 feet before stopping. I'm lucky no car or person was in front of me. Honestly not a skid at all. Service tells me I don't know about anti-lock brakes but I've driven with them on cars for many years with nothing like this.

I am having an issue where my Navigation display on my 07 Prius wont respond properly to touch. Like i would press in the left corner and it registers in the right. So i have given up on fixing it and just going to buy a new unit. My question is how can i tell which unit i need so that it fits and i still have all my options that my car has. I have an 07 model with navigation, back up camera, Bluetooth, leather seats, JBL audio not sure which exact model it is tho.

My 2007 airbag sensor does not respond to a weight of 20 pounds or more, it continues to read "off". The dealer said the problem is in the female end of the seat belt; however, the seat belt sensor works perfectly. It sounds like the wrong diagnosis to me.

After putting my Ford Ranger in park and pressing down on the E-break to get the news-paper or mail. I've noticed that there is a consistent squeaking coming from the back drum brakes when the brake pedal is applied. But only for a certain period of time; then the squeaking stops.

My Prius Navigation Sceen/Climate Control/Info screen will not respond to touch input. When I try to input anything, when I tough the screen, buttons to right of where I am touching come up. For example, on the info screen, when trying to go to the settings screen, all I get is the numeral zero.

Long story, but I bought a 2007 Prius with 73K miles on it. Now I'm at 93K miles, and I think it may be more jerky than when I got it when I shift the tranny into "brake" mode.
I don't know if the fluid has ever been changed on it, and I intend to change it very soon now. Am I in a pickle? Or should this transmission be fine if the fluid hasn't been changed for 93K miles?
