Prius (2010-12) :: Hums At Slow Roll - Metallic Harmonic Vibration
Mar 25, 2012
I just replaced a 2005 with a 2012. The 2005 was dead quite during slow movement and parking while the 2012 hums. At first I thought the hum was a rubbing noise but on closer listen it sounds like a metallic harmonic vibration. It reminds me of the sound of rubbed crystal glass except lower in tone with metallic undertones. It is audible from outside the car or when the windows are down. It does not appear to be associated with movement as it comes and goes during the three point manuever required to park under the carport. Is this is normal or I am heading back to the dealer?

The other day, as I got up to speed on the interstate on moderately wet asphalt, a harmonic vibration started at around 65mph. Felt it in the seat of my pants more than in the steering wheel...the entire chassis was vibrating. So bad that when I called a friend to ask him what he thought, he could hear the vibration in my voice. Clutch in, engaged, under power, under back pressure - nothing affected the pitch or harmonics. Below 65 changed the intensity, but had to slow to 50 to make it stop. Took it all the way to 90, but no difference. This kept up for the entire 70 mile trip.
Now for the weird part. On my way back, 2 hours later, the rain had stopped and the interstate was now dry. No vibration. Just as smooth as glass all the way home. I had it in for service recently, because it happened once before...no codes, no clue from tech as to what brought this on. And just to be sure, I had them balance the wheels...very minor weight adjustment. I called the dealer on the way back to tell them it happened again, and all the tech could suggest was to stop by next time it was raining so they could road test it.
Even more weird is the fact that this has only happened twice and I drive the interstate in the rain all the time.

I bought a 6,000 mile RX back in december and notice the vibration at slow acceleration.
It sounds like it's coming from the rear of the vehicle. It stops when it gets up to speed. I looked for anything lose and don't notice anything underneath.
I'm not too impressed with my local dealer so far to have them look at it. It sounds as if something is loose inside the muffler. It does not vibrate upon rapid acceleration.

Is there a way to mod the automatic windows up and down. What I mean is that If i arm the alarm with remote, all four windows will automatic roll up. The honda accord has the function which will roll down the windows by the remote before you enter.

Just recently got a 2011 Prius II and i love it. Only having one issue. Sometimes when i hit a bump with the windows open, i get a metallic clunking noise, but if i hit a bump immediately after it, I don't hear it again. Maybe 5 minutes or so later (not exact at all), If i hit another bump it will happen again. Seems to be on both sides of the car. Car has 5k miles so I'll be bringing in for service next week. Does this sound normal or is it something i need to have looked at?

Every bump, slow or fast from left or right side of the car there is an obvious metallic clunk or rattling sound.

I only notice this when I back the car from the garage and come to a stop before going forward. It is a very metallic clunk. It sounds like its coming from the rear passenger side but I am. not 100% certain. It happens when I actually stop before switching to drive.
It is a 2013 Two. 30,000 miles on it.

Having issue with power windows in 2010 Prius. I just noticed today that I can't roll down the rear passenger side window from the driver door switch but all the other windows work, and the rear passenger window works as I can roll down from the door itself.

Noticed a weird metallic rattling noise coming from the transmission when switched to N with the engine running and the car is stationary? Almost like the gears are rattling inside while in N position. I took it to the dealer and their Prius guru said this is normal characteristic of eCVT....

On the December day my 2013 Prius Five model (hatchback with all the safety add ons, bigger wheels) turned 18 months old, i was on the way to have one of the freebie services. I heard a metallic rattle, seemingly coming from the back of the interior. It continues and I cannot find a source for it. I just read a thread about rattles in the 2011s. Not particularly comforting given what I spent on the car.
Is this something I could have the dealer chase under the warranty? (this is the first new car i ever bought in my 50 years of driving, so my familiarity with new car warranties is a little thin.)
My dealer has been pretty responsive -- swapping out an interior door panel as a freebie when the armrest portion separated from the lower portion and collapsed into the door.

So I noticed this when I had my windows down and the music off (or very low) for the past few weeks (at this point). About 3800 miles on the car, and maybe once or twice during a drive It is an occasional clank/ metallic noise that sounds like it is coming from either the left or right side depending on which tire hits the bump. But I can go over any number of bumps before and after with no noise at all, and it's not like I'm hearing it on just large bumps/ potholes. I've never heard it on any speed bumps.
I have a feeling it is when only one tire drops down a bit from a small bump, but that is only a feeling, and it's on small bumps. I tried looking up other threads on here for suspension noise, but mostly only finding things dating back to 2011 or so with brake caliper pins, possibly motor mount but nothing really recent.

I've recently been having a metallic creaking/rattle go on when idle or moving at slow speeds. I took it in during my 20k service and they said there was something with a cable and the heat shield... the service manager had also said something about the catlytic converter - but when I re-checked the service slip - nothing. This was originally in March.
The noise came back again recently so I had a different dealer check it out when I finally had the fuel tank recall done. They confirmed the noise and checked the heat shield (I had told them about the original complaint), but said there wasn't much that can be done - they made sure all the bolts were tight, but the noise was coming from the heat shield "flexing."
Most of the time it's fine and the noise went away for several months. It's subtle again, but if it becomes constant - it seems like I have a valid argument to have the heat shield replaced - seems defective.

1988 Bronco II 2.9L Issues:
- When I turn off the wiper switch the wipers immediately stop in place, they do not continue to their normal 'down' position.
- The switch's adjuster to slow the wipers isn't working, only the low and high settings work.
What I've done so far:
- Replaced wiper switch with used from spare parts.
- Replaced wiper switch with new from spare parts.
- Replaced wiper motor with remanufactured from Autozone.
- Thoroughly cleaned wiper motor ground terminals.
- Replaced interval wiper governor with used from spare parts.
The problem occurred after the truck sat in my garage for 6 months while I removed and reinstalled the engine to replace some gaskets & seals.

Was about three blocks from home when the front of the car started making a horrific metallic scraping sound as the front wheel turned. I mean LOUD. Did a quick look for something stuck in the wheels somewhere but nothing. It's not like a branch stuck in the wheel sound, but scraping a shovel on a steel beam kind of sound. Braking seems to change the makeup of the sound, but did not stop it. Parked it in the garage.
I pulled the left wheel off, looked and looked, and looked. Nothing. Fear and sadness setting in. Everything looked normal....except....a faint line on the rotor very near the inside edge. Got a mirror and looked some more, and there, wedged on the inside edge of the pad's metal part and the rotor, was a rock the size of a bb. At most. Got a small screwdriver and hammer and popped it out. Done. Sheesh.
Seriously it was so loud it was amazing. So store in file folder for future reference if needed.
The line can be felt barely with a fingernail and is half the width of a pencil lead, and goes under the innermost 1/8" of the pad. I'm thinking do I want the dealer to pull and turn it, or is it going to affect my braking at all. Pretty much gonna leave it be I think.

I've noticed that when I take right or left turns at slow speeds I hear a series of clunks. Sounds like a pipe rolling in the bed. Guessing it has something to do with the rear springs??

I have a 2005 Limited and whenever I roll any of the windows down it does a quick rattle vibration like its trying to pull away from something that's sticking then it continues to roll. It would be 1 thing of it was just 1 window however its all 4 windows. I thought originally thought maybe some of the rubber molding I seen on the windows, (maybe from the days it was hot over the course of years) were the reason and wiped all the black stuff off the windows with goop. Didn't work. I didn't realize how bad it was until I moved my old 2001 Avalon I'm selling and they rolled down so smooth..

I know it's stupid but rattles and vibrations in an otherwise quiet car drive me absolutely crazy.
So, driving I have noticed this slight non-metallic vibration type noise. It seemed to come and go. So I emptied the car thinking it might be something I was carrying around. No such luck. Turned off the climate control, still there. I had the better half drive while I searched. I could never really see anything but thought it sounded like it might be either in the dash or around the floor area. Totally frustrated I unbuckle my seatbelt and crawl into the passenger floor head first. Nothing on the passenger side. I glance over to the Driver side footwell and notice the slightest vibration from a panel that covers the steering shaft as it goes through the firewall right behind the pedals. Aha! A plastic panel being held in place by 2 plastic type screws that are both loose. i tighten them down with a straight screw driver when I get home and silence! The rattle goes away. You might look at yours as well. I think this might apply to all Mk5 cars. Finding/Fixing a rattle like this for me is like finding money.

Yesterday I took my car out, stopped at a gas station and the car wouldn't start. When trying to start it, everything inside would come on but it would just click. We were able to jump start it. After that I was able to start it 2 more times. the next time i tried to start it, it did the same thing, but the jump didn't work. We went and bought a new battery and it still isn't starting. It isn't clicking anymore though. It kinda hums when it tries to turn over. Does this seem like a starter issue?

Had my JoeZ exhaust installed at my first oil change at the dealership about a month ago.
Anyway, late last week I noticed on cold start in the morning I'm getting a metallic vibration noise. This is on gentle acceleration out of my subdivision. It disappears within a minute or less and doesn't re-occur until the next morning. Best way I can describe the sound is a cell phone set to vibrate sitting on an aluminum cookie sheet.
Any hints on what I can check that might be the culprit? I already checked to see if the muffler tips are hitting the exhaust diffusers but they're clearing and I can reach up around the canisters and fit my hand up around them so they're not touching that silver heat shield material.

I have a 2010 Prius Pkg 5 with around 71xxx miles. I usually drive it like a regular car on eco mode and get around 38mpg average but recently I've changed my style of driving where I accelerate to the desired speed limit, let go of the gas, then reapply and keep the mpg meter in between the middle eco line and before the pwr band. I've been able to average 44mpg this way, which is great!
However, what I've begin to notice now is that say if I'm traveling at say around 45mph and let go of the gas and re-apply, the engine starts to shudder as if it's not getting enough gas. Why this is happening? I also need new tires (215/45/17) but that doesn't have anything to do with this. I've owned this car since 30xxx miles and haven't done anything other than put gas and change the oil at the dealerships. Could putting 87 octane gas with up to10% ethanol have any effect on this?

I running into a bit of a strange tire problem. I recently had the tires replaced on my 17" wheels. I ordered the tires online and had them installed by a local garage. Ever since then, I have been having what appears to be an intermittent leak from my left front tire. I'd typically fill the tire to 42psi in the morning and, by the next morning, discover it to be around 34-35psi. My commute each day is approximately 100 miles round-trip. This is very repeatable.
I have been back to the mechanic. He removed the wheel and very carefully examined the valve stem, rim-tire bead, sidewalls, and treads for any leaking using the soapy water method. We couldn't find anything.
