Sonata I45 (YF - 2011+) :: Loud Humming Sound Like Compressor Or Something Kicking On And Not Fully Engaging
I took my car in to get this checked out, but they say they can't hear it.
Sometimes when I turn my car on right after I turn it on, there's a loud humming sound like a compressor or something is kicking on and it's not fully engaging. And it only makes the sound for maybe 3-5 secs. Sometimes it won't happen when I turn the car on, but when I'm driving and I let off the gas and go to touch the brakes, it'll start.
The best I can describe it is a 'hum'...but it's loud, and I can feel it as if it's near the gas pedal right behind the firewall.
Dealer thought maybe it was the ABS switch testing itself..but they could never reproduce....I got in after they replaced my rims and checked it...and it did it 4 times when I started it, then turned it off. He came out to check, and it was almost as if you couldnt hear it outside of the car.
So, what the sound might be...I can't reproduce it anytime I'm there. Figures...... but I hear it almost daily. He put some foam tape on the firewall behind the gas lines saying the 'pulsing' from them might be doing it...but it did it again this morning.

If you listen closely, you can hear a weird humming sound while it's idling, not sure what it is. It doesn't happen all the time as far as I can remember.
Lexus ES 2013+ :: Humming Sound From Rear Under Carriage
My ES350 is always parked in my garage. One afternoon, I went into the garage to get something and I heard a humming sound coming from the car. It was very hard to identify where it was coming from. It sounded like a low horsepower compressor of some sort. I put my ear next to the rear wheel on the drivers side as this was the area the noise appeared to be coming from.
This is the second time I've experienced this happening. A couple things to note:
1. The car had not been operational for at least 8 hours.
2. There was no indicator lights on the dashboard flashing.
3. All doors were closed.
4. It seems to happen intermittently and I can't replicate on my own.

View 5 RepliesGolf V R32 :: Odd Humming Sound While At Idle In Right Rear Inside?
This is my first all wheel drive car and same goes for having a car in which the battery is in the rear floor. My question is the following.. Whenever the car is on and radio off I hear a humming sound while at idle. At first I thought it was the SAT radio (while vol all the way down) but that was not it. Its coming from the rear right side and almost sounds like a fuel pump/something electrical. It kinda sounds like a transformer or something like that. Since the battery is in the back and there is a fuse relay box aprox. 3 inches from the spare tire, I wonder if all these electronics are making this noise? Or is my car coming to life?

Bought a 2014 SD 4x4 in December of 2013 and this is the second time the big girl has been to the shop with A/C problems. First time it was the evaporator about three or four months ago. During the last few weeks of the summer I began to smell something strange (like band-aids) when the A/C was on and it lingered until the next re-entry. ALso, began to hear a slight hissing noise when the compressor was kicking in and out. They replaced the evaporator, smell remained as they said it was the refrigerant I was smelling. About two or three weeks ago the smell got slightly "larger", and last weekend she would not cool. This is the fourth time shes been to the shop with other problems such as the My Touch system..............

It is as an electronic whistle/humming. The sound is coming from the rear of the van, and no, not when it's moving, even though it still does it when moving. The only thing I can think of would be the fuel pump. Because It's loudest just before the rear tires, not after them. My fiancee has heard it twice now, when she first heard it, I didn't, but this last time when I heard it, I also noticed that the gas gauge was reading just below 1/8 of a tank.
Would like to know if it's the fuel pump or something else I'm no thinking of. And if it means I have to replace the pump.
Corolla / Matrix 2009-13 :: Loud Humming Sound At The Rear When Reaches At 40 Mph
I bought a used 2010 corolla and notice a loud humming sound at the rear when it reaches 40 mph. I figured it was the rear hub bearing assembly. I already bought a pair of Beck/Arnley 051-6262 hub assembly. I found two threads here about the removal/installation but did not say the torque of the 4 bolts behind the hub assembly. I read on the Toyota Manual that it is 74 ft-lbs. Do you think that this is too tight for a 10 mm back plate. The wheel/rims bolt torque is 76 ft-lbs but the nut is about an inch length. It is almost the same torque for an inch nut compared to 10 mm back plate. Is 74 ft-lbs right especially for an aftermarket beck/arnley brand? On the Toyota Manual, the 2003-2008 Corolla 4 bolt torque is 45 ft-lbs. The 2010 is 74 ft-lbs???
View 1 RepliesMercury - Grandmarquis :: Low Humming Sound While Driving / Leak Coming From Behind Rear Right Tire
So today while driving my '98 Mercury Grand Marquis home I noticed a leak was coming from behind the rear right tire.. Or I'm guessing it's a leak ? But it's kinda like a grease substance and it sure does smell bad! It's all over the backside of the tire and muffler (probably why it smells).
While driving it there is a low humming sound? Best way I know how to describe it and if I go over 60mph it gets increasingly louder.. After looking up some forums online I came across that it could be a possible wheel bearing or maybe a bad axle problem?
Sonata I45 (LF 2015+) :: Slight Hissing Sound Coming From Under Rear End - Exhaust Leak?
Well I've just noticed something quite annoying today... a very slight hissing sound coming from under the rear end of the car. A friend I drove to work this morning even said "what's that noise?".... It reminds me of the sound you'll hear when there is a pinhole in a joint weld, or a clamp is loose? My car only has 2800km on it!
View 8 RepliesGolf IV R32 :: Kicking From Rear Under Acceleration
So I've been getting this weird kicking from the rear end when I am accelerating medium-hard. It only happens for the first 3-5 minutes after I start up the car. I first noticed it months ago when entering a highway. At that point, during acceleration, it felt like the throttle was slipping. It would happen again and again in about 1-2 second intervals until I shifted out of gear.
During this "slip," the car stops accelerating briefly until it engages again, then it slips again... repeat. However, lately it has been much worse and has changed to a very prominent "kick" from the rear end. I can feel and hear a force from behind me, in addition to the acceleration stopping momentarily. It has started happening in low gears and lower speeds, too. It happened today just turning onto a road end speeding up to traffic in 1st or 2nd gear.
It definitely feels Haldex-related, like the Haldex clutch is slipping maybe? The thing when this happens I don't feel like I'm accelerating so hard that the front wheels slip and the Haldex kicks in, but maybe I'm underestimating the 4motion assistance.
I'm at about 77k miles, and I've read that every 40k you should get the Haldex serviced (oil & filter change). Could I just be due for that? Or might it be a much bigger issue?
Ford - Ranger :: Kicking Sound In The Transmission When Cruising
I sold a buddy of mine my dad's old 1997 Ford Ranger XLT with about 100,000 miles. It passed an inspection and was in good condition. Afterwards we both noticed it had a kicking sound in the transmission as you were cruising with it. It was variable but on average about every 20 mins or so. My buddy thought it was probably due to overfilling with fluid so he had it flushed but the problem still remains. He thinks it gets worse as it heats more. We're not sure what the problem is.

I'm the proud owner of a 2005 MK4 1.8t gti, and recently it started making a weird sound when it starts kicking in to boost, where it would normally make a whistle sound while the turbo spools up it now makes a sound that reminds me of a supercharged car, it feels like it could be a leak but I don't have an ecl popping up, it does kind of platoes in the powerband, I hope I'm making some sense ..

I have a 2011 with 42k. While doing a front brake job, I noticed that the driver's side wheel hub while rotating it sounded noisy, it did not rotate as smoothly when compared to the right side. I have also noticed while driving that their is a slight humming noise from the front but always attributed it to the Bridgestone Turanazas. Maybe it is the tires and I just over reacting. Is this normal for the hub? Here is a video clip with sound. Is this wheel hub going bad?
View 3 RepliesCamry 2012+ :: Car Making A Kind Of Slight Humming Noise Only For A Second
I have a 2012 Toyota Camry SE I4 with about 34,500 miles. I have noticed that over the past 2 weeks, the car make a kind of slight humming noise only for a second. It only happens first thing in the morning after the first start of the day. Its not right away, it happens after I pull out of the driveway, and as I drive away it happens at about 10 mph. The noise will not happen till the following day after a cold start. I have tried to pinpoint the sound and it doesn't matter how long I let the car warm up and it doesn't matter if the heater is running or not. It will still make the noise. The car runs good other than this noise.
View 4 RepliesCamry 2012+ :: Slight Humming Noise During Initial Acceleration At About 8-10mph
This noise sound as if an electric motor going off for a second only. It almost sounds as a CD changer changing cds but for a second only.
What is weird is that it only sounds when the car has been off, turn it on and I start accelerating to about 8-10mph. If I come to a complete stop at a stop light and accelerate again it will not sound. If i come to complete stop and put the car in park or N, it will not sound. You will only hear it on the first take off when the car has been off.
I would also like to point that I have manually shifted and this does not change a thing. The noise still comes on around 8-10mph even if I keep it in 1st gear.
Furthermore, I would also like to point out that the noise is is not loud. Chances are I will not hear if I have radio on at low levels or the A/C fan in mid to high.
Again, the sounds seems to come from the outside the cab and it sounds like an electric motor going off for about one second only.
The car is a 2012 l4 with about 60k miles on the odo.

View 3 RepliesSonata NF (2006-10) :: Rhythmic Humming Noise If Give Slight Throttle At Around 50 Mph
09 i4 AUTO 47K miles ... When the car is running at around 50mph and if I give it very slight throttle (enough only to keep speed constant), I would hear this rhythmic humming noise. The hum rhythm has a frequency of about 1/2 second each. It is very muffled, almost like exhaust noise or tire noise. However, if I downshift to 4th gear, keep the same speed, and apply the throttle in the same way, the noise doesn't occur.
View 13 RepliesTiguan :: 2012 - Trans Stays In Higher Gear And Makes Vibrating Humming Noise
We just brought home a new Tiguan 2012 Automatic and when we are in Drive (D) and going about 26-30 mph the transmission stays in a high gear (5th) and makes a vibrating hum.
It happens on a flat road when someone is in front of us and forces us to stay in the 26-30mph range.
It feels like it wont drop back to 4th at this speed and is overloaded in 5th. When we give it some gas it will hum and lag even more then finallly downshift.
Tiptronic and Sport seem fine but Drive does not feel normal in this range.
When we took back to dealer at 130 miles on the odometer, the tech sat in on the drive and experienced the symptom. His conclusion was that the car is in its "Adaptive Learning" phase and it should work itself out after about 600+ miles.
