Prius (Gen 3) :: 2012 - Whistle Noise While Driving
May 23, 2012
I'm a newbie so still getting used to my 2012 Prius III. The other day while stopped at a red light I decided to run out and open the trunk for my work badge that I left in my briefcase. It's a long light and I knew I'd have plenty of time. I put the car in Park and put on the parking brake then ran out. When returning the light was still red, so I put the car in Drive and waited. After it turned green I hit the gas gently but noticed the car did not move.
The car behind me hit his horn, so I hit the gas harder and the ICE kicked in and started moving the car a few feet. That's when I realized the parking brake was on and released it. Since then I'm noticing a whistle noise when I drive slow. It seems to be there when driving in EV and with the ICE running. It's not the noise maker but a higher pitch noise. Could I have done something to MG1 and MG2 when I hit the gas harder to move the car. It sounds like an electric motor high pitch sound. It may have been their before but I didn't notice it until now.

I never had this problem with my previous car and I'm using the same phone and 1/8" cord.
I get a loud whistle noise sound whenever I try to play through the AUX input. I have a 2013 Prius 2.
How to get rid of the noise?

Currently having a possible 'issue' with my 2012 Passat 3.6. Every time I perform a hard acceleration, or any time the RPM's exceed 4,400, I can hear a whistle that is rpm-based coming from the engine bay. It is quite notable from outside as well, and ONLY occurs when the A/C is ON. Is this something I should be concerned about? I never hear it when hard accelerating without the A/C on. It is a high pitch whistle that increases in pitch the higher RPM's that are reached. Sounds almost exactly like a turbo, but as soon as I change gears in the acceleration, the pitch instantly drops back down but still matching (pitch-wise) rpms in the next gear and continues again.
It's loud enough to hear it in the cabin, but not over, say, 6 of volume on the radio.

Got my Accent on June 30th, has 8500km on it already and I love my car.
Recently, I've noticed a sound coming from the passenger side when stopped at lights or when I've just parked. Best description would be a bit like a crackle (liquidy/whistly type of sound). Only happens when the A/C/defogger is on.
It's not very noticeable, I only hear it when I don't have the radio on, but it's been bothering me. I found a few posts about a rattle, but from what I can remember, it's not really a rattle.

Hear a high pitched whistle inside the cabin while driving above 60 mph? I can even hear it over the radio most of the time, with the windows up! I have found it to be the mirrors! After hearing this noise, and pinpointing when it occurs, we finally found it is the mirrors. When they are folded in at speed, the noise disappears completely. I had it to the dealer, who couldn't pinpoint it, and I was trying to blame it on the tires, but found this instead.

I noticed this rattle/whistle on one of the 2012 camrys we test drove and now I am hearing it on the one we purchased. when on the highway with the radio off or down low I hear the rattle/whistle. (almost like a jacket zipper rattle) It sounds like it is coming from near the top of the drivers door.

My car occasionally makes a high pitched whine while driving it's very loud and very frustrating. I've come to the following conclusions: It only happens when the car is warm, it only happens at speeds above 40mph, it doesn't correspond to either accelerating or decelerating, it happens either way and in between. I've had people in the car while it's happened and the noise seems to come from the driver's side rear wheel. Sometimes it gets so loud and then gets even louder when I begin to apply the brakes, it's as if it starts screaming.
I've had mechanics take apart the complete brake system on every wheel and put them back together. They've put anti-squeal on the brakes to no avail. While driving the noise can come and go, with no apparent reason why. It happens in rain and on warm sunny days. Also, the noise seems to oscillate as if it is something that's spinning, I'd guess it's at approximately 160 beats per minute. This has been occurring for about a year, it was not this way when I got the car. No mechanics have ever found anything, but it's so loud! And so annoying and embarrassing. This can't be normal, what is it!?

Yup, my truck randomly whistles while driving in cold temperatures. Its not life threatening or damaging to the truck, its been doing it for a few months not that its been getting below freezing. Its just REALLY annoying. I can even hear it over my radio at times, so its pretty dang loud outside of the truck. The noise originates from somewhere under the hood in the engine compartment.
Won't do it at lower speeds, usually on the freeway. Motors at about 2k rpm and im going roughly 65-70. Change the rpm when it whistles and it goes away. happens randomly from 50mph to 70mph engine speed from 1.8k to 2.5k rpm. I've tried to find it but can't find a darn thing since it won't make the noise while sitting in my driveway. What it might be?

My 2005 Ford Freestar with 164k miles experiences a high pitched whistling noise coming from the front end after a few minutes of highway speed driving. It sounds like a tea kettle whistle. It starts out as a quick pulsed whistle then moves to a solid whistling noise. I've heard it driving straight and turning. The sound pulsates if I turn the steering wheel slightly to the left or right but seems to occur more when I turn right. The sound does not occur if van is not in motion and will stop just before car comes to rest at a stop. Three repair shops have looked at this and none of them can replicate the sound while van is on a lift but one shop did hear it during a test drive. All three shops have been unable to locate / diagnose this whistling noise. They all state brakes are in very good shape.

I have a whistle from my 2000 f250 super duty when driving over 60 mph. windshield is new, seal around windshield is good (looks good to me).
whistle sounds like its on right side when driving, and left side when sitting in pass side. wife narrowed it down to the over head console sunglass pocket is where whistle is loudest.
Could the clearance lights be whistling? How does one tighten them up or add sealant to the bottom of them to seal them to the roof. Do I have to drop the front of the headliner to access them?

My 2004 has suddenly decided I should drive with dome lights on all the time, as if starring in an episode of COPS. Seems something is reading my driver door is not closed, even though it is closed. Besides lights on, unable to use controls to roll down window or lock vehicle. Also, there is now a whistle emanating from the bowels of this silver beast. Seems back near the fire wall or underneath. Sadly, this 2004 JGC does not even have 150,000 miles and things are going south for the winter to retire in Florida. Had one form 1993 and it lasted over 400,000 miles and my 1999 had 250,000 before I met Mr. Ice. On top of these goings on's the right rear wheel is causing a scraping noise, but not 100% of the time.

I recently noticed that I'm getting a high pitched whining noise after I drive anywhere then stop and turn off the car. The noise is a buzzing/whining sound that lasts about 10-15 seconds and then stops. The noise sounds like it's an electronic component maybe having to do with the transmission? What it might be?

When accelerating I hear a whistle noise from the engine after 4k rpm. The whistle noise becomes higher as the rpm increases.

I've been all over the place trying to get this pulley sounding noise figured out. the noise is definitely not the pulley, but is coming from that side, and from underneath the engined towards the back. this noise only occurs when car has been driven at least 30 minutes to an hour from first start of the day, but then continues the rest of the day. the noise also only occurs when I am coming to a stop or just rolling at a low idle, and then only lasts for about 30 seconds and goes always until i give it so gas and the noise comes back.
I know its sounds a lot like PVC, but i have had all that checked and actually pvc replaced. Took it to another VW dealer, and they charged me for diagnostics, and came up with it the noise was coming from somewhere in the clutch, and want to replace the whole clutch, that was just replaced by them 20,000 miles ago. You would think if was coming from the clutch it would make the noise at all times. Do you think it could be the clutch in any way?

Had very cold weather the past few weeks. Took my car out early in the morning last Thursday (after warming it up) and there was a loud squealing noise from the heater for about 2 minutes when I was driving five minutes from my driveway. Since then, I have this faint squealing noise that can be heard anytime that heater is on. It loud on the first two settings.
Took it to Toyota and they said it was normal due to the cold but from past cars I've owned, it looks like the blower motor could be on it's way out? Can this be true? Car has 11,000 miles on it.

I have a 2012 golf R with about 25500 miles. I'm getting this high pitch noise coming from the front of the car. I can only hear it with the windows down. It is intermittent, sometimes doesn't show up sometimes there. Gets louder when I turn right. What am I looking at? Wheel bearing? I'm on coilovers.

PIP does not charge the plug in battery while driving....
View 19 Replies
I had my brand new plug in prius for 6 whole days before my house was hit by lightening, while the car was charging. The car has been in the shop for 3 weeks since that has happened and they eventually replaced the "electric vehicle recharge unit". But it still doesn't seem right to me. one of the things that is happening is that the EV switch is not operating while I'm driving.
For instance: I'm driving locally on EV and then get on the highway and when I get to the point that the engine kicks on, I hit the EV switch to turn it off and move to hybrid mode. However, even though the EV light is off, the battery continues to discharge and will eventually completely discharge. To prevent this I do a number of maneuvers like hit the brakes repeatedly or hit every button the dash (EV, ECO) until it stops!
This cannot be normal but then again I only drove the car for 6 days before lightening struck. It also happens the other way. If I'm driving on the highway and get off and then hit the EV switch to turn the electric back on, the electric motor doesn't kick in.Am I imagining this? Is there some fancy way to switch EV and back on the fly?

I just bought a 2012 Prius c. There are oftentimes when I don't drive my car for a few days. When this happens, I have heard that the car might not start, especially in the winter. Is this true?

From my understanding, there are 3 batteries in the PIP. 2 of them are for EV mode, and 1 is for Hybrid mode. they are all hooked up together and also the electric motor when it is fully charged. when the first pack (ev pack) get's depleted, it will disconnect via relays from the remaining 2 packs. then when the second pack is depleted (second EV pack) it will discontinue from the last remaining pack. below is a small simple diagram of what it looks like:
Fully charged: (EV1)-----(EV2)-----(HYBRID)-----[motor]
1st pack depleted. still in EV mode: (EV1)---x---(EV2)-----(HYBRID)-----[motor]
both EV packs depleted and in HYBRID mode: (EV1)---x---(EV2)---x---(HYBRID)----[motor]
(x = disconnected)

If I'm driving around town and have to accelerate to merge with traffic, the ICE will come on even though I'm in EV mode. I understand why that would/should happen. But why does it stay on for so long after that? It seems like it stays on for several minutes, even if you're driving slow after the the few seconds of acceleration. And I've noticed a few times under the above circumstances that the ICE is clearly on (I can feel it's on) but the dashboard indicator shows it is off. What gives?
