Purchased a used 2010 Gen III a few months ago and have noticed a fast buzz, felt through the floor and brake pedal. It is intermittent but the conditions needed are:
1) Air conditioning running at high speed
2) Vehicle in Drive
3) Immediately approaching a stop, and a few seconds after stopping.
My 2015 Prius with 1,300 miles on it makes a rumble/grumble/moaning/groaning sound after I have come to a complete stop. It can be felt in/on the brake pedal. (Stop light, etc) It lasts for a few seconds then stops.This low rumble has me concerned. It has a slight vibration to it too. (again this is NOT while driving. Only once stopped and foot resting on the brake pedal) I can't confirm it has anything to do with the braking system but seems to come from the general area of the brake pedal and when foot is on the brake. So I assume it's the brake system.
I know about the typical brake servo actuator noise (which is completely normal and I am very familiar with) but thats a light unintrusive noise. Distinct from this low grown noise. (I know the difference) I hope I am correct in assuming the computer would detect if there's anything wrong and throw a light... but I'm new to Priuses. Is this a normal sound/vibration? I know these cars do a lot of electric things so if it's normal, I'll try to ignore it.
Has intermittent buzzing sensation through both the brake pedal and accelerator when at low speed or stationary? I drive a v10 diesel. I am aware of the normal vibration associated with a diesel (which is near non-existent in the Phaeton) but this is something very different.
View 23 RepliesSo I purchased my 2015 Lexus IS 350 AWD F-Sport back in October and experienced the following issues:
1. Brake squeal
- seems to occur when reversing out of a parking spot for example, so annoying and extremely loud, makes it sound like my brakes need changing
2. Bluetooth Radio
- there are times where my phone connects to the radio, plays music off my iPhone but then it sounds like the singer is slowly dying i.e.: the type of sound you used to hear when a walkman's batteries would be dying and needed changing. Happens sporadically
3. Gas tank lid on side of car won't close fully
- this happened just this week. I couldn't close my gas lid, no matter what I did. I managed to get it closed today after starting my car, wonder if its related at all to power/engine being on etc?
4. Buzzing in gas pedal resonates through foot
- this one is still driving me insane. Drive my car for 10-15 minutes on the highway and your foot feels like pins/needles from the buzzing sensation from the gas pedal.
Bought the car used a few months ago with a little less than 72k miles. At 72k miles, I replaced all brake pads. Car now has 75k miles on it. Wife just got back from a 1k mile road trip with it.
I took it for a little ride, and noticed this problem about 3 times, it doesn't happen every time. There is no vibration or anything when slowing down and stopping. But, a few times, when the car was at, or almost at a complete stop, the brake pedal would feel like it was buzzing a little bit, and I could hear a springy sound. I tried to reproduce it with hard braking, but couldn't. Seemed to only happen with slow, gradual breaking, and when the car was just about at a complete stop. Brake fluid is full. No lights on dash. Asked my wife if she slammed breaks at all, or had any problems, she said no. Then she said she experienced what I did once, when she was at a rest area, stopped
The only thing I can think to compare it to is how the brake pedal feels and sounds if you lock up your brakes, and the ABS is doing its thing....which I haven't ever done with this car...
ABS, Traction, Brake (red & yellow) bulbs in.
ABS not working
Reduced brake efficiency
Heated brake disks
Regeneration charge indication doesn't go to left side much. But slightly charges battery.
ABS fuses ok in engine room
No vacuum sound in brake pedal
But faster brake actuator sound (every 5sec stop 2sec sound) on stopped ready mode in P. Engine not running.
Bit history;
I had brake light fuse blown. But not knowing was pressing brake pedal hard to start / goto ready mode as display said. So after replacing fuse, had the traction bulb on. After it was reset. Everything was fine. Apart from increased vacuum sound in brake pedal.
It seems about once a week the rubber cover that goes over the food pedal for the parking brake comes off. I've been careful to replace it correctly but it still keeps happening? Btw it's a 2010 v with atp ...
View 9 RepliesI had a problem with my brakes about 4 months ago. They were making a barking noise when I stepped on the brake pedal. The dealer bled the brakes and reflashed software. Now the problem is back and they say I probably new a new brake actuator. It should be covered by the extended warranty. I hope a new actuator will fix this. I like everything else about the car. (Have 37,000 miles)
View 16 RepliesI am looking to buy a 2012 Prius and I test drove it. Everything seems ok except each time I press the brake pedal there is a swoosh noise its as if air is being released from somewhere and I can easily hear it. Is this normal? the car is 95000 km on it. The dealer says it might be a normal hybrid noise. I currently have a 2007 Prius but that does not make this noise.
View 5 RepliesI recently purchased a new (to me) 2010 prius and I've been noticing that sometimes, but not always, I hear a fairly loud noise when lifting my foot off the brake pedal. It sounds like a squeak or squeal, and I want to say I can almost feel a tiny bit of resistance in the pedal when it happens though that could be in my head. The noise does NOT occur when pushing down on the pedal (only when lifting), and it seems to only occur when the car is stopped.
View 7 RepliesThis has happened twice now, about a month ago and then again today.
I was stopped at a light with my foot on the brake. There is a clunk noise, then the indicator light comes on.
The first time I tried to go, and the car stayed put. I hit the parking button, then went back into gear, no problem.
The second time I just put it in park and then back to gear. No problem.
So I noticed this has happened a few times.. If I press on the brake pedal too hard, the indicator light will come on and then turn off a few moments after I depress the brake pedal. This has happened when the car is stationary as well as when I was coming to a stop, it's happened maybe 5 times since I picked the car up a few weeks ago. Is this normal behavior or an indication of a problem? Just an FYI, I'm not talking about when the indicators light up when first starting the car.. This is tied strictly to pressing the brake pedal hard.
View 8 RepliesI recently purchased a 2014 Prius with the package 5 trim. I'm completely loving the car, but noticed when stepping on the brake pedal I hear a soft "swoosh" noise from under the dash. Almost like a short vacuum or sucking sound. The car has 500 miles, and I don't recall hearing that noise initially.
View 16 RepliesI have the regular Prius 2012, The brake pedal is attached to a rod that goes into a flex boot and then into the ABS module in the Engine compartment. The Boot is leaking sticky greasy/oily fluid. It not a constant leak. Its like it leaked on a Hot day and then stopped leaking.
Its not the one from my car, but its what I'm calling the ABS Mod Is this not just the lubricant for the Pedal or is this real brake fluid from the ABS module leaking into the Car? took it to Toyota and they said they had never seen this before and they are recommending to replace the entire ABS Module and Brake Fluid at a cost of $3346 + Tax. (roughly $2700 in parts)
We have a new 2015 Prius with 6k on it and we are noticing one solid brief single click when the brake pedal is pressed and/or released. It doesn't happen every time (just some of the time) but it is only noticeable at slow speeds.
View 19 RepliesI have a 2010 Prius Hybrid and lately, on an intermittent basis, I will press the brake pedal and push the start button and the dashboard lights up as normal but when I go to put it in gear nothing happens. The last time it happened the fan was running and I couldn't turn it off. It's like the car is all set to go but all the interior controls don't function. I then shut it off and restart it and everything works.
View 1 RepliesI have a 99 Blazer 4x4 with ABS. Brake pedal just went to the floor and car stopped eventually ... a bit scary. I've checked all the brake lines and the inside of all wheels and there is no sign of fluid anywhere. All pistons seem to be where they need to be with backing plates nicely visible.
I pumped the brakes quite a few times and same result ... but I'm not pumping fluid on the ground. As expected I've also checked the reservoir and its full. Didn't see any leaks so its full. I'm guessing that the master cylinder has given up the ghost ... truck has 470,000km so things wear out.
I'm getting this checked today most likely as it's been happening for months now. No issues with vibration and stopping is fine. As a matter of fact brakes are excellent. However when I'm stopped at a light or whatnot and I depress the brake pedal there's a pulsation that occurs almost every time. It's fairly constant and only happens when I'm at a stop not when I'm stopping so I know it's not a warped rotor. What it might be?
View 4 RepliesAfter almost 12,ooo miles, I'm starting to experience some kind of buzzing resonance that come through to the dash, console, and can feel it in the gas pedal. It's weird because it will happen when accelerating and decelerating too, but not it's not a constant occurrence. I wondering if the motor mounts are loose? The ICE runs great and the transmission seems to be operating as smoothly as ever. It's just odd that this started just recently.
View 1 RepliesIs it normal on the 2.0T that when you are driving and stop at a red light to get vibration that you can feel in the car and hear in the motor? As soon as you let off the break it stops and the engine stops the noise. I don't drive the car enough really (my wifes) to know if it is normal or if this just started. It is an 07 and just turned 12k on the weekend trip. Also, having a problem on Sat radio with there being a high pitch hum in the back ground? [IMG] [URL] ...
View 13 RepliesI have a Camry at 120K now. Front brake pads was placed at 85K and was told by the maintenance person at that time that brake rotors couldn't be resurfaced since they were close to the minimum thickness.
Braking seems still fine these days. I don't hear any high-pitched noise or feel obvious vibration/pulsation when the brake is applied. The brake pads are still within a good range of thickness as the last check was made a couple of months ago.
But the brake pedal is softer than before so that now I have push harder to get car stopped. It that a warning sign which indicates it is time to replace the brakes rotors and pads?
