Prius (2004-09) :: Booming Resonating Noise In Cabin At Idle And Low RPMs
I own a 2007 Prius Touring w/120kish miles. We are currently experiencing a huge booming resonance at idle and low RPMs. The noise isn't subtle, almost sounds like we're in a Huey with the doors open. Here's what I believe I know:
- No DTC's are being thrown
- ICE seems as smooth as ever
- No apparent changes in fuel economy
- Plugs were replaced 40k ago and coil ignitors are original--not running rough or missing though
- Visual inspection of exhaust shows no leaks or contact with body
- Motor mounts pass the test I looked up [in drive/reverse, depress brake, watch unusual engine displacement]
- Noise is not vehicle speed related, only engine speed coupled--probably between 1K and 1.8k rpm
I'm sure I'm leaving something out but aside from messing with the coils or plugs I've looked at everything I can think of. I haven;t gone to the dealer yet. Lot's of reading searching have only revealed CV issues.
Touareg :: Subtle Hesitation In 3rd And 4th When Accelerating
I've noticed that my V6 and the 2 dealer's loaners have the same subtle hesitation in 3rd and 4th when acceleration. Casual, everyday accelerating. Less noticeable if you hit it hard.
View 5 RepliesTouareg :: Oil Temp Running Very Low - Subtle Rumbling?
As temperature in Michigan has dropped I am noting that my oil temp is running very low; after 8 miles in the morning, it doesn't come off the peg, and with outside temps in the 30's, does not climb above 180. My erratic mileage seems to have deteriorated with that, and the subtle rumble I noted in the first 4,000 miles seems to becoming more pronounced.
As much as I love this vehicle, I'm starting to regret the purchase. After 8 years of a flawless Tahoe and 3 years with a flawless 528i, the Touareg is frustrating me.
Santa FE SM (2001-06) :: 2005 - Ticking Noise / Blue Spark Occurring At Random Intervals On The Balancer
2005, 2.7l. FWD automatic, with 180,000+ miles.
A week ago it started making a random ticking noise I've never heard before. Today was the first chance I got to try and find it and I'm stumped on what could cause this.
The sound is a static or low voltage electrical discharge coming off the harmonic balancer. I can actually see the blue spark occurring at random intervals and locations on the balancer as the car is running.
Do i need to be looking for a bad engine ground? I'm having no other electrical problems. The car runs like a champ other than a minor oil and power steering fluid leak.
Prius V :: 2012 - Subtle Vibration Like Buzzing Noise
Bought a brand new 2012 Prius in California - Power Toyota in Irvine. It was heavily raining so did not test drive. Package 3.Next day noticed that there was excessive road feel and buzzing like vibration.Took the car in and they noticed it too.
Changed Goodyears to Yokohoma, checked suspension and tire pressure. Issue did not go away. It is subtle but constant. Dealership said there is nothing wrong with the car and every car drives differently. Offered to change car with me taking a hit of 5000 dollars. It is like driving on a stone like rough surface with a buzz like vibration.Other cars I test drove did not have this. Two of my friends have 10 and 11 Prius they did not have the problem. They also felt the Buzz/Vibration in my car.
Passat (B6) :: 2007 - Subtle Clicking Noise When Driving
My B6 only has 1500 miles and I have noticed after I had the dealer replace a defective fuel rail w/only 400 miles on car a click'n noise when I am driving.
For example. When I take off from a stop, and accelerate to lets say 15-20mph and then take my foot off the accelarator, let the the engine(rpms) idle back to normal, and then re-accelarate again, immediately I hear a "CLICK" (only one x, and its not a really loud, its kinda subtle, but still you can hear it from inside the car) coming from under my feet area, very briefly and then the car takes off.
At first I thought this was normal, but of course I could not dismiss this, seeing that this is a brand new car, and figured........"well it shouldn't".
BTW, I just tinted my windows (35%) on my black B6 and it looks fantastic.
Prius (2010-12) :: Subtle Clicking Noise From The Engine When Accelerate
When I accelerate, particularly between the 50-60 mph range, the engine makes a very subtle, yet definite clicking noise. Mentioned this to the dealer - the car is still under warranty - and of course, they can't replicate the sound..is this common?

I recently purchased a 2011 Hyundai Elantra GL 4 Door. I am noticing a horrible but hard to define noise. It is like a whine (like power steering pump) but not because there is electric power steering on this car, it also is kind of a mechanical grind - can't really define the sound I will try to record and post later. Any way... the sound occurs when accelerating, the harder the acceleration the worse the sound.

View 7 RepliesCamry :: Subtle Clicking Noise - Blower Motor Works Intermittently
So for a few months now, my car has been making a subtle clicking noise whenever I have the ac or heat on, kind of similar to the noise spokes on a bike would make when children put a card in them. The noise increases/decreases in speed as I adjust the ac/heater speed.
Recently though, it's gotten to a point where sometimes, the blower motor would completely stop working. I can still feel heat and cold coming through the vents when I turn the AC on, but the it doesn't always blow air. I've noticed that sometimes when I hit a bump in the road, it starts working again. It works at all settings and all temperatures perfectly (when it's working that is).
How should I proceed? I don't know much about cars, but from what I've seen on the internet, it doesn't seem too difficult to replace the blower motor. I just want to be sure that the blower motor is indeed the cause, because I don't want to install a new one to be disappointed when I turn it on and still have the same issue. And winter is just around the corner so I would love to get this taken care of.
Lexus GS 2013+ :: F-Sport Subtle Clunking Noise From Front And Rear End
Recently picked up a CPO 2013 F-Sport and I've been experiencing a subtle clunking noise over sharp bumps (like raised expansion joints) or potholes at speed. It's a very subtle clunk that comes from the front and rear end, not attributable to any specific corner of the car.The sound completely disappears when I flip it to Sport+ mode, leading me to wonder if the noise is just inherent to the adjustable suspension. Additionally, I didn't notice the noise until after a new set of Michelin Pilot SSs which replaced some cheap dealer tires (Accelera Phis) with very soft sidewalls.
It's not an alarming noise but it does have 53K on the odo so I'm curious as to whether this is indicative of impending bushing/strut issues or if it's normal and other F-Sport owners experience the same noise.
Prior to this I had 2009 STi (low profile tires, stiffer suspension) and never heard any clunking type noise over these same bumps (expansion joints, potholes) so it does have me slightly worried.
Toyota - Corolla :: Subtle Rattling Noise When Idle Or At A Stop Light
I purchased a used 2010 Toyota Corolla LE with about 40k miles back in February of this year. Since then, the car has been issue-free and has responded accordingly.
Two weeks ago I noticed that the car when idle or at a stop light it'd make a subtle rattling noise (as if it was something behind the glove compartments rattling against metal). At 1st I thought maybe it was something inside, but as that week turned to days, I noticed that while I was outside the car and it was on and idle, I could hear the rattling from the right side of the car under the passenger seat (closer to the engine, as if right below where the glove compartment sat)--It is a constant rattle at the same frequency..meaning it doesn't rattle one way 1st and then another later. It sounds the same, but it is random.
It evolved from a subtle rattle inside to being a loud rattle outside under the car. I noticed that if it was rattling and I turned off the air, the rattling would stop, but after 20 seconds, the rattling would return just not as frequent.
It was advised to me that perhaps it was the blower...but the blower sits behind the glove compartment and should not sound so loud under the car. Not only that, but if the blower isn't on (when I turn off the air) it shouldn't sound...at least that's my logic for it.
The sound is getting louder and more frequent at this time and I'm just not sure what to do about this. I live in Miami, FL and hearing so many rip offs at mechanics, I don't know what this rattling is and I've already crawled under the car and see nothing wrong, nothing shaking violently, nothing.
Golf V R32 :: Subtle Whining Noise Coming From Underneath The Passenger Side Of Car
I just upgraded from an '08 GTI to an '08 R32. When I start my R, I get this subtle whining noise which seems to be coming from underneath the passenger side of the car. I stuck my head under the car to try and determine where it is coming from exactly, but I couldn't really tell. It's not a loud noise, but I hear it whenever the car is running. I did a search for it, but I couldn't find any posts describing this particular noise.
View 11 RepliesPrius (2001-03) :: Subtle Knocking Noise For Few Seconds When Start The Engine
Recently, when I start the engine (cold or even warm starts) I hear a subtle knocking noise that doesn't last too long but a few seconds. I figured that maybe it's because our area may still be using winter mix gasoline... but I'm not sure. Also, there's a rattle underneath the car when the engine switches into generating electricity with MG1.
This only happens after a start-up procedure (cold or warm). It stops when I push the gas pedal down a little bit (while still in park) then it goes into charging again, and by that time, it's stopped. I figured it may be a heat shield on the exhaust. It sounds more up in the front.
Also, when I start the car, the engine starts smoothly but then 1-2 seconds later goes into spinning MG1 which makes the car kinda sound like "vrrrrrrr---VRRRRRRRRrrrrrrrrrr...." .
Passat (B5) :: Subtle Vibration / Buzz Noise Coming From Dash Area
I recognize the odds of isolating this is low, but thought I'd try. I have been hearing a a very subtle (but noticeable) noise coming from within the dash area of my 2002 Passat (mostly near the glove box side, but also in the middle area). Noise occurs when the ignition is turned on - with or with out the engine running. It can be heard while driving, but is more noticeable when I turn the HVAC fan to off. The sound is random, and seems to be like a relay dithering, an intermittent buzzer or a fan noise (although no fan is on.) It sort of sounds like a cell phone vibrating randomly in the glove box.
View 2 RepliesSanta Fe (CM - 2007-12) :: 2008 - Booming Sound From Engine And RPM Needle Fluctuated Up And Down
About 10 seconds after I started the engine, I could hear booming sounds from the engine and the same time the engine rpm needle fluctuated up and down and I could hear the engine seemed to die down and then went back up again together with ups and downs of the rpm needle. This issue just happened recently (about 2 gas tank fill-ups ago). When I started to drive I had the same problem at red lights as I could see the rpm needle fluctuated. The problem got worse when I engaged AC. However, I did not have any check engine light on. I tried a different gas station but no luck. I even used higher octane gas (93) but still had the same issue. I've got only about 15000 miles on the santa fe.
View 7 RepliesCamry :: 2004 - Subtle Noise Coming From Blower Now Stopped Working Intermittently
My 2004 camry LE (235K miles) has had a noise associated with the blower for several months. The blower worked fine on all settings but had a subtle noise that was between a purr and a click. It's constant, fast-paced, rhythmic and rises in pitch as the blower setting is changed. Hot or cold settings don't make a difference. The closest I can approximate is the sound made when kids put (or used to put) playing cards in the spokes of their bikes.
However in the last couple months the blower has stopped working intermittently. Sometimes it will come back on if I went over some railroad tracks or a hard bump. If I turn the car off the blower may not work when it's restarted. The last couple days it's stopped doing even that, and since there's snow on the ground it has become an issue! The fan setting doesn't make a difference, high or low.
