Prius (Gen 2) :: Intermittent Pumping Noise With Vibration Near Driver Left Foot
Aug 14, 2016
My son just changed my oil, radiator fluid & transmission fluid on my 2007 Prius with 125,000 miles. Now it makes a fairly quiet, intermittent pumping or quiet growling/humming noise. A vibration can be felt near the driver's left foot when the noise is heard. The noise starts about a minute or two after starting the car & goes on & off, about every 30 seconds, for the entire time the car is running or driving. The car seems to drive normally, although I've only driven it a few miles, a few times. The only unusual dash light is the "maintenance required" indicator which has been on since before the fluid changes.

Just bought a 2010 Prius V and am noticing a ton of road vibration in my left foot transmitted through the floor. Is this normal? Poor dampening?

When driving my Prius v3 (2,700 miles) I can feel some vibration / wobbling / modulation directly under my left foot. It seems to be fairly consistent regardless of road conditions. I took my car to the dealership today and they told me that they also felt the "issue"... stating that it appears to be coming from perhaps the engine mounts. They also said that they could feel in in the gas pedal. However, they also said that this was normal. In other words, they could not find anything wrong mechanically with my car. So... Good news and bad news. This is "subtle" but definitely there. I think now it's bothering me even more. I find myself moving my left foot around to try and reduce the modulation.

The carpeted footrest on the left driver's side of my C has a bubbled/raised area on the left side, which causes my foot to roll inward uncomfortably. It feels wrong but it doesn't really look wrong, so I don't want to waste a trip over to the dealership if the area was just poorly designed. Do footrest accommodates the whole foot comfortably or if there is a raised area under the pinky toes? I'll see if I can get a picture.

For many months now, I've heard what sounds like some kind of pumping noise. This happens after starting the car and may go from brief to a few minutes. Seems to happen after every cold start and often even when warmed up. Some starts are soundless. I only recently discovered that it's coming from under the hood beneath the relay/fuse box. I can't see where it seems to be coming from.

Every time it rains the carpet is very wet by the left drivers foot. I have cleaned out the drain behind the front wheel and used a heavy gauge plastic mono line to clean out the drain for the moon roof. Unfortunately it still becomes wet. My next area to check is the drain from the area at the bottom of the windshield. How that can be done? 2000 Camry XL....

My 8-year-old (2003), 134k mile Nissan Maxima has a new quirk. When the car is started from completely cold (as in over night), there is a distinctive intermittent squeaking noise (think water being rubbed against glass) coming from the left front somewhere near the tire. The car only does this for about 5 minutes or so until it's warmed up and it has to be going 20 miles an hour before it starts. Once the car is up and running you can turn it on and off all day, let it sit for a few hours even, and it's fine. What's going on?

So on my girlfriends 2000 echo I get the classic bad wheel bearing noise/vibration on the front left (driver side) wheel. Worsens under load (right turn) and goes away when unloaded (left turn). I've replaced left side bearing, CV axle, brake rotors/pads and the noise still persists. My next thought is maybe the ball joint but humming/vibration tells me something out of rotational balance. Bearing in the transmission? I don't know. I'm stuck.

This was quite unusual for me, but while I was driving down afternoon highway traffic, my left resting-feet accidentally bumped onto the e-brake. My Prius made a single beeping sound, but I don't think I fully depressed the brake at all so it kept on rolling and the e-brake light never stayed on.
I wonder if that did any damage to my Prius at all with a slight depress of the e-brake or if it wasn't anything at all?

All passengers in my 2016 Three Touring notice some intermittent plastic noise near the driver left knee. Just a few squeezes sometimes. Definitely not electronic (braking or others). Feels like dashboard plastic noise.

It acts like it is fuel poor, As if the fuel pump is not pumping. It spins fast on start. Then another try and it starts! No relationship to hot or cold. Fuel OK. Battery strong. I find no corrosion on fuel pump leads.

I've made a video of the pumping sound in that seems to get "stuck on" repeatedly at occasional times while the car is in operation or at idle. What it is and if it should not be going on like this without stopping? The car is a 2004 Canadian model, assuming it has the coolant thermos.

I have a 2006 Prius (150K miles) with a noise coming from the drivers left wheel. It is a hollow metallic squeak that only occurs while the vehicle is moving. It sounds like the wheel is making brief contact with something metallic at the same point on every rotation. The pitch of the squeak increases with the speed of wheel rotation. It does so while rolling, with breaks and without. The noise gets louder when turning right, and softer when turning left, though it begins to get louder again when the wheel is turned hard all the way left.

My 2002 camry has a vibration feel while pumping the brake pedal (no other vibration from car). It happens, when you drive slow or fast and stop. Happens when the engine is not even turned on and the brake pedal is just pumped. Its hard to describe the feeling other than zig zaggy on the way down, pulsating, etc. It starts to feel this way on the way down and halfway through the press ends smooth.
I took it to a auto mechanic two days ago and he stated the car had zero brake issues. Rotors and pads are in good condition (sometimes these are the cause for the vibration, but only when driving and stopping), fluid level are good etc. I asked him to test it out and pump it slowly or adruptly, at standstill or while driving, but he still couldn't understand what i was talking about. Researched on the net and found out the likely problem has to do with either Brake booster pump or Master brake cylinder. From a tsb (like a recall note from toyota, see below) , it seemed certain it had to do with the master brake cylinder. I took it to Toyota today and they stated it had to do with the brake booster pump instead , its not worth fixing bc it cost an arm and a leg. Just now i stopped by Active Green + Ross at 110 Gerrard and he stated that its most likely the Master Brake Cylinder, since if you were to pump on the brake while the car was off, turn on the ignition, and if the pedal goes down smoothly , the booster pump should be ok. (it does go down smoothly)
He also stated that for a refurb master cylinder (non toyota) + labour it would come out to 250 bucks. The dealership was going to charge me 1500 for the booster pump and labour. They also advised not to used non toyota parts.
This issue does not hamper safety issues with the car. Its more of an annoyance that i'd like to take care of. I also don't want to pay 1500 for a car with 150k on it.

I have had this intermittent clicking noise from the front left wheels. It sounds almost like a rock wedged in the tread but its not. I checked and the tire is clean. I inspected as much as I can see but see nothing abnormal. Any clue what the deal is?
I stared having the noise right after having the front left tire replaced and it seems to happen when the brakes are hot. I don't hear it in the morning or if I let the car cool down and drive it an hour or two later. My brakes are original rotors at 74K miles and the pads are probably in the 45K range . Not sure what the deal is but it drives me crazy when I can hear with the windows down ( I live in AZ its still in the 70s). I had an issue like this with my GS350 but cant remember what fixed it or what the issue was .

2000 Expedition AWD, 4.6l ... 150K on car, 50K on trans, 150k on transfer case and most else.
The problem is, under load, there is a intermittent bearing vibration noise...it sounds like a roller bearing that has too much tolerance so it vibrates in and out under acceleration. You can feel it in the gas pedal and chassis, you can hear it, and it robs a little power when the sound it pronounced. The sound is 10x worst when towing my 6000lb boat. Gear doesn't seem to matter, but it is hard to make it happen in 3rd gear.
Diagnostics so far:
-Can't reproduce sound on rack or out of gear
-Stethoscoped all accessories - good
-added Lucas oil additive to engine oil - no change
-added Duralube high mileage goop to trans - no change/slight change?
-Aamco said it was transfer case, tear down and inspection revealed nothing, they said it was mostly pristine for a car with 150K on it.
-Inspected U-joints - all tight
The duralube in the transmission may have made a slight difference in the frequency of the sound...but it could be my imagination, it wasn't significant enough a change to be determinate.
I think I could isolate the issue with a diagnostic tool that doesn't exist as far as I know...it would be a handheld device with 4 magnetic mic sensors you could stick in various locations and watch the waveform output on the handheld... you would simply move the mic's around until you got the highest amplitude on the readout.
At this point the only thing I can think of:
-Aamco missed something
-Main bearings, cam bearings, or possibly oil pump
-Transmission bearing (Aamco says "NOT")

4 cylinder car engine that doesn't shake like a tractor at idle ? I've got a 3 cylinder tractor that idles smoother.
I like my Elantra except for the tire/road noise and the intermittent BAD vibration at idle. It shakes the whole car. Odd that it doesn't do it all the time. AC seems to make it worse......sometimes. I think I can fix the road noise with different tires but fear that the dealer is going to say:" Nothing wrong. They all shake like that at idle."

In the past month I have had 4 instances (approx. once per week) of vehicle vibration/shuddering. The first time I thought for sure I had a flat tire and pulled over immediately and had a look at my tires. All was fine and I continued to drive with no further vibration.
My Prius v ( lowercase v for the Prius v wagon ) has 50,000 kilometers. Has had all required service at our local Toyota dealer. It has always been a pleasure to drive, smooth and quiet. Has only been on paved roads and the tires are in excellent condition.

Over the past few months I'd noticed an intermittent grinding noise coming from my left front wheel at low speeds. I took it in once but it refused to play along so I finally managed to catch it on camera and let the dealership listen to it. They booked me for today, saying it sounded like a wheel bearing (to which I agreed) and I dropped her off around ten, not expecting it to cooperate for the second time.
I got a call from the dealer around 2 PM saying that they were able to duplicate the noise and that when they took the left front wheel off and ran the car on the lift with the rest of the wheels off the ground, the noise went away. Even stranger still, when they put the wheel on the tire balancing machine and spun it, gronch, gronch...gronch, gronch....gronch, gronch. It was coming from inside the wheel! I gave them permission to dismount the tire from the wheel and about ten minutes later I got another call saying they'd found a handful of tiny hard rubber balls inside the mounted wheel/tire assembly that were rolling down the inside of the wheel and causing the grumbling at low speed.
Here's the kicker: they were in all four wheels! The tech even saved them for me so I could take a look and they don't look like anything mass-produced; some are larger than others, some are round and some are oval-shaped but when I dropped one on the glass advisor desk, it made a very clear 'Clink!'.

Upon moderate to hard acceleration I hear an intermittent spinning-like vibration noise from the rear diff area...is that normal?

I have 2005 Prius, 53K miles on it. Bought it as used car few months ago. It has been running great since then.
Since last few weeks I have been hearing a soft beep every time I take foot off the brake. Today I had my windows down while driving and I realized that the soft beep is actually a loud noise like squeak or beep. I can hear a noise every time I take foot off the brake (NOT when putting foot on the brake).
Anyone can standing near the car or other car drivers at red-light can hear the sound too.. This happens when- the Car is in D, I take foot off the accelerator and press the brake (to slow down or complete stop) then take foot off the brake.
