I have a 2003 Acura TL with ~200k miles and an automatic transmission. Recently, I noticed a whirring noise at low speeds <20mph, but only while coasting. The noise goes away if I hit the brakes or if I hit the gas, even if I manage to maintain the speed below 20mph. What this could be?
View 1 RepliesI have a weird issue with my 2002 4x2 manual Nissan Xterra...when I drive along (usually happens when I'm in 3rd or 4th gear), and depress the clutch pedal to start slowing down for traffic, while the gear lever is still in the 3rd or 4th gear position, the rpms start coming down as the car coasts, but then a strange grinding/whirring/grumbling noise starts happening. The noise immediately goes away if I pull the gear lever into neutral, OR if I re-engage the clutch to start accelerating again. So, it only happens when BOTH the clutch pedal is depressed, AND the gear lever is "in gear". What could this be? The car has about 115K miles, but I believe the previous owner changed the clutch recently (80-90K), and the clutch itself feels fine.
View 3 RepliesMy car developed an "intermittent" accelerator whistling noise coming thru one of the speakers (I think). The harder you accelerate - the louder the whistle. When idling, it sounds like an open air whirring noise. Of course every time I bring it to the shop - it stops and when I hear it it's never convenient to get to the shop!
View 4 RepliesI'm bringing my 6MT 2.0T in tomorrow, for 10K service, installation of the Euro-cupholder and to have them investigate a sound I first noticed last week. For lack of a better description, it's a "whirring" noise that is exactly proportional to speed (higher pitched at higher speeds). I'm guessing that it's either related to the clutch or the drive shaft.
I can't hear it well with the windows open. It seems to emanate from under the stick-shift. It is audible either in gear or not. (And it seems to be getting slightly worse each day).....
High pitched whirring noise when the climate control fan (compressor?) is running at low speeds. It doesn't seem to matter if the air is on or not. I'd like to know what it cost to fix and if it is covered under most extended warranties.
View 4 RepliesI have a new 2012 Chevy Cruze with 10,000 miles on it. Chevy has issued service bulletins citing a problem that they can't seem to diagnose or repair (yet) and my car has the problem. They tell me their engineers are working on it. After the car is a little warm, when I apply the break there is a loud squeaking or whirring noise which pulsates at the speed of the tires (in other words, as I slow down, the intervals between each sound gets longer and longer). I suspect it is coming from the back. First they thought it was sticking calipers until they realized that I have drum brakes on the rear. It is loud enough that the only way no to hear this grating noise is to blast the radio.
View 2 RepliesMiddle of May, I went to Boston. On the way there, I started to notice a slight whirring noise that was only present when I gently feathered the gas to maintain highway speed. If I were to apply any more throttle, the noise would go away, and if I were to pull my foot away and allow engine braking, it would also disappear.
So I did my best to finish the trip to and from Boston adjusting my driving to avoid the noise. Once I came home, I researched and thought the noise might have been my wheel bearings (I had just replaced lower control arms, lower ball joints, inner and outer tie rods prior to leaving for Boston). I also had a shop install my upper strut mount bearings and bushings simultaneously with the wheel bearings.
Since then, the problem still continues. It has grown louder, but still occurs under the same situations. I've focused more on it and here are the conditions under which it occurs:
1. Car must be warmed up. Starting it up cold and allowing SAI to run then driving, car is fine, no sounds. Usually takes 20-25 mins of driving to get it to start making noise.
2. Car still only makes the noise when the gas is being feathered (ie barely pressing it enough to give it any sort of throttle. It does also make the noise between shifts when reengaging the gear and applying gas, as the throttle pedal passes the point of throttle off to throttle on.
3. I'm hearing more noise now during engine braking than I had been previously. Could be related?
I have a 2004 F-150 SCrew Lariat 4X4 with 80K miles. Over the past month or so, every once in awhile there would be a loud metallic "clacking" sound (kind of like sticking a peice of aluminum in a bike's spokes) that would start at higher speeds and would turn into a low pitched whirring gear sound as I slowed down and eventually there would be a thud followed by a sensation of running over a small bump and the noise would be gone. Kind of confusing I know, but that is the best way to describe it. My gut feeling is a wheel bearing or transmission problem....

View 4 RepliesTransmission comes out of gear and has a loud whirring sound when in reverse, but not every time. it has happened when driving at about 60 mph (twice) Sometimes it happens a couple times in a row sometimes it is ok for a couple weeks.
View 2 RepliesI've got a 2005 Volvo V50. High Mileage (230000). Timing belt replaced at 200k. Runs really nice, until this evening. Inserted the key and turned over but instead of starting it made whirring robot noises and read "brake failure message" and "immobilizar" after turning key to off position. It's really cold out. 0 degrees. What's the next move?
View 2 RepliesMy 03 F250 7.3 is making a grinding noise when I let my foot off the accelerator and coast in 4x4, I replaced the hubs with new warn premium hubs and it is still making the noise. The noise does not occur when I take it out of 4x4.
View 2 RepliesI just installed the Donaldson B085011 filter last night. I understand the swoosh noise when shifting is normal. But, I noticed a chirpping when coasting. I first suspected suspension parts maybe but after reading on here could it be surge? I've seen some videos of what surge sounds like and it does sound like that but most people say it only happens under load and I'm hearing it just coasting down my farm market road to a stop sign without hauling anything. I'm researching billet compressor wheels now. Am I on the right trail to resolve this?
View 10 RepliesYesterday coming home from Morgan Hill I noticed my injectors making a odd sound on all the down hills while coasting - IPR % would drop between 9.8-9% making it almost sound as if the motor was about to complete shut down, RPM range was 500 -800 rpm, ICP 450-550 but the motor almost had a sputter to it... no codes, lights and it didn't run weak or have a lack of power but I've never noticed it before ...
ICP is only a couple years old
IPR is about 1.5 old
Both replaced with OEM parts .. Is this normal - or do I need to start digging somewhere?
The Throttle Body on my 2001, 4.6 L is making a strange whirring noise, when you puy your hand on the intake pipe, you can feel a slight vibration. The Truck idles and runs okay, with no codes. Giving it a little gas and the noise goes away. The last thing I did was clean the IAC with Gum Out Carb cleaner, the second or third time I've done this over many years, with no problems. I'm a little perplexed at the cause.
View 6 RepliesI am now getting a random 'whirring' or 'squealing' noise from the front. When it starts, I feel some vibration in the steering wheel and floorboard and for sure can hear it. Starts on it own at random, sometimes when I hit a bump in the road. Stops at random, sometimes when hitting a bump in the road. Lasts for different lengths of time. Always stops when coming to a stop at about ~15 mph. Seems to change pitch ever so slightly if turning when it is 'whirring' or 'squealing'.
View 4 RepliesSo I've noticed something on my 2015 Elantra that I haven't noticed on my previous car (Corolla). When I'm coasting at low speed (i.e. when I see a stop sign/red light I'll just coast until I'm closer and then press the brakes) it feels as though the brakes are sometimes being pressed when I'm not actually pressing them. Is this normal? Why does it do that? I'd like it to not do that as it's kinda annoying. Sometimes it "brakes" enough that I actually have to press the gas again otherwise the car is going too slow, which defeats the purpose of why I'm coasting in the first place as I do it to save some gas.
My Elantra has an automatic transmission if that matters.
I've noticed that when I'm coasting to a stop and my speed gets to about 27 MPH, the transmission downshifts (RPMs increase) until I reach about 22 MPH. I'm not applying the brakes at the time.
It's a bit annoying as it sometimes bleeds off just enough speed that I need to accelerate to reach the point I was planning to stop at. Is this normal?
I have a 2012 SE 4 Cylinder Special Edition and just hit 60,000. Lately, I have been noticing this vibrating/shaking in the front of the car when I'm coasting or accelerating at a slow speed. What it could be? I got my front end alignment done thinking it could be that but it still continued.
View 7 RepliesI have noticed over the past month that as I am maintaining speed, I will have a vibration or shutter. It sounds and feels like you are running over the cuts in the road on the shoulder. I can accelerate and make it stop but as soon as I want to maintain speed it will happen again. It does not feel like there is anything going on in the transmission. I have searched the forums and have found some similar problems but not exactly. Where should I look first? U-Joint, Drivesahft?
View 1 RepliesI am getting a light clicking from my rear Axel when coasting at a slow speed. It could be clicking at any speed but my car is to loud to hear it going down the road. I don't have more details than this. What to look for ?
