Prius (2010-12) :: Road / Wind Noise Coming From The Rear Passenger Area
Mar 31, 2015
I've owned a 2012 Prius Two for less than a month now, and today while driving home I noticed what sounds like road/wind noise coming from the rear passenger side area. Googling about this revealed information about the battery fan. However, I'm unsure if what I'm hearing is the battery fan or road/wind noise that I just haven't heard before.
Here's information regarding the conditions I was driving in:
- 84 degrees outside temperature
- car had been sitting in an open-air parking lot for about 2 hours
- no tint, no windows cracked for hot air release
- upon returning to the car I turned on the AC to 68, set at mid range speed
- was driving on the interstate doing some stop-and-go, but mostly 50-plus MPH
- windows rolled up completely, no doors ajar
- it sounded like air rushing by
- could not hear anything coming from the left rear side, but my left ear is partially blocked by the headrest, so...
- sound would decrease in volume if car slowed down
- sound would increase in volume as car got faster, but would eventually level out it seemed
- sound would completely go away at speeds below 20ish mph
- sound would not change based on level of AC, whether on, low, high or off
- checked battery vent for obstructions/debris, saw nothing, and was cool to the touch
- car has about 28k miles on it, replaced rear tires yesterday but all bolts, caps, etc. are securely in place

We have had our 2010 with 20k miles for about 3 weeks now. I can honestly say that I can't remember being more disappointed in car. Specifically, the road and wind noise above 60 miles an hour can at times be unbearable. The Prius makes the inside of my 14 year old BMW sound like a Lexus.
I thought it might be the tires since the originals were worn. We had an unrepairable leak in one tire so we went ahead and put brand new Michelins on the car. There was only a minor improvement in noise.

I have a strange "wind noise" at 70+ mph -- only coming from the passenger side -- definitely the mirror area. I think the door seals are OK and the problem is the painted mirror cover making a sound (resonating/vibrating) when the wind hits it at high speed (I was tapping on it with my fingers and I could see where this might happen). So I went and got some Dynamat type stuff to put on the inside. But I cannot figure out how to get the cover off.
I saw a couple posts on people installing the turn signal indicators, with pictures of the mirrors half torn apart, but none of the posts mentioned how they got the painted cover off. I tried to pry it off by jamming my fingernails in a crack and getting a hold, but that's not working.

For the past year I would occasionally hear a wind noise from the backseat on the passenger's side. It seemed to coincide with acceleration so I figured that a seal had come loose. I took it by the dealership but they couldn't figure out what was wrong. A few days later, I heard the same noise but for the first time ever, it actually got louder when I was stopping so I figured out that it wasn't a seal.
I was lucky enough for the issue to keep going even when I parked so I found out that it was air being forced out from the A/C system(from vent near the seat cushion). What would cause this? I almost might think something wasn't grounded properly. I had another weird issue like this(not air but intermittent) on my old Jeep and it ended up being a grounding issue.

I seem to be getting a creaking noise (the same sound you get when you lean on the armrest) coming from the passenger side rear. It sounds like it is coming from the hatch, but I can't quite narrow it down. The creaking noise appears when I drive slowly over bumps.

I have a rather annoying high pitched tone coming from the front passengers side widow/mirror area. The dealer says it's normal wind noise from the mirror and can't do anything about it. I think they are just being lazy, and I think it's actually a window seal issue.
Here are more details; I hear the noise typically only at speeds above 60-65mph, although I have heard it as low as 40mph, but was driving into a head wind (so the combined air speed was about the same). It is a high-pitched, high-frequency noise that almost sounds like a continuous tone. It is loud enough to be annoying even with the radio on at moderate volume. It will disappear completely at speeds lower than mentioned above. It is localized only to that one side. The drivers side mirror/window is silent (for this issue at least) no matter what speed I am going.
A recent road trip gave enough frustration on this issue to make me begin experimenting. I taped up various mirror seams in a number of configurations and none alleviated the noise. At one point I rolled down the window about an inch to see If I could hear it more clearly from the window. The noise disappeared but I thought the turbulent wind noise at that speed might be masking it. So I rolled the window up and then just *tapped* the switch down the slightest amount and to my surprise the high-pitched noise disappeared completely, yet I did not open it enough to hear regular wind noise. This all leads me to highly suspect a window seal issue, and not mirror noise at all. Cracking the seal so slightly must allow the pressure to equalize canceling out the noise.
When I took it in for the issue they say (of course) "Can not replicate, wind noise from mirror within factory spec, no action taken" and something about cracking the window "re-aligns the flow over the mirror into the cabin reducing the noise" sounds because the drivers side is as silent as the grave, and the mirrors are symmetrical to my knowledge.

I'm having a real issue with wind noise coming from the A pillar area. I've been to the dealer twice and still have no resolution yet. When I went in today and showed them where the wind noise is coming from the tech. just stood there dumbfounded like he's never came across this problem before. Tried blaming it on wind noise around the mirror. I showed them how when you close the door on a dollar bill there is hardly and force needed to pull the bill out. They adjusted the door striker the first time which didn't work any. There are some major alignment issues with the door and the seal. It's so bad water leaked inside the car during a heavy rain.

We have an 07 Prius with around 150,000 miles on it.
A couple of weeks ago I noticed a slight knocking noise coming from the passenger front wheel area mainly when I was turning toward the right.
Question.......So when turning to the right, it first seemed to me that the right side would experience a heavier load. However, after further thought and applying some physics the inertia of the car would actually be putting a heavier load on the left side during a right turn. Which is correct?
Just trying to troubleshoot the noise/problem.
#1 when I apply the brakes, the noise doesn't change. I don't think it's brake related.
#2 the noise speeds up with speed, meaning that it's rotational.
#3 The noise does get louder when I am turning right but has know progressed into a constant noise going straight. During a left turn it subsided.
#4 I did take my floor jake and jaked the pass. front wheel up but didn't see anything broken or damaged. I couldn't rotate the tire though.
#5 I also had the tires rotated today and the noise got worse.

I noticed when driving on a rough surface/road (gravel, snowy road with sand) the there is a considerable amount of noise coming inside the cabin on the rear end especially.
When I was doing a quick wash today I just realized the sound is coming from the wheel base. On the rear and front end there is a plastic covering the wheel base. Sound proofing / undercoating wheel base.

Notices such a noise from the rear passenger side door (same side as the fuel cap. Also experienced this same window 'malfunction'. Lowered it partially and then auto-rolled it up. Instead of auto-rolling up to a close, it rolled all the way up and then all the way down where is stopped.

I made my first round trip from Vegas to LA over the weekend in our 06 GX470and had to endure this obnoxious wind noise that seems to be coming from both driver and passenger windows. Is this normal for a Lexus SUV? I normally drive my LS460L which is dead silent so I'm not sure if I'm just spoiled. I used to have a big SUV (Armada) but never noticed the wind noise because of the engine and road noise.

How is the wind noise in your cars? Noticed once I hit about 35 mph that there is a good amount of wind noise coming through the passenger side.

I am wondering how much fan noise is normal from the passenger rear vent while driving.
My fan is on almost constantly and it sounds like wind coming in through the rear window but it is actually the fan from the vent. I have had passengers in the front seat ask what the noise is coming from the rear. I have taken it into the dealer 3 times and they say that is normal for Prius' to have that noise all the time.
My Prius is 2011, bought on Feb 2, 11.
I have 5000 miles and the noise has been present from the onset of owning the vehicle. I am really frustrated because it sounds excessive to me. Is your fan on most of the time and significantly audible?

Experienced an occasional (not always) rattle in the passenger rear area of the 2012 Elantra GLS. I have a video on YouTube of this specific rattle that I will post eventually, it says i have to wait a few days until I can post links on here.

So we are taking a short trip and my dad decides he would like to drive my new passat. That means I get kicked to the back seat as my wife will not give up her heated seat. We are on the highway now and I noticed for the first time some very annoying wind noise coming from the rear headliner between the door and the small window. It almost sounds as if the widow is opened a crack but I checked.

Having issue with body squeaking ? . I am getting a squeaking sound coming from around the passenger rear door /body area of my 2010 Passat. Car has 10K miles and has been doing this since around 6K miles. Not noticeable unless going over uneven pavement or railroad tracks but it is annoying. Never had any body squeaks from a new car lite this. Have not been to the dealer with this issue yet.

Noisy Fuel Pump ??? At least that's what I think it is. Pretty prominent whirring going on, sounds like it's coming from the rear passenger area. Dealer listened to it, agreed something was up. No immediate answer, will have to schedule service.

I've been noticing "Hissing Noise" coming from the rear passenger side (rear right hand side) of my 2011 Prius for a few days now. It sounds like the hissing noise is coming from the vent that's located on that side. Not sure what that does, but the hissing noise is usually present when I'm driving at 10MPH or up and it's gone when I'm less than 10MPH or at a complete stop. I have about 32K miles on the car.

I have considerable road noise coming from both the driver and from passenger sides; have done a little research and found this to be a persistent problem with most Subaru models with frame-less doors.
