I own an AT 2004 TSX with 18,000 miles. I've been noticing a noise that could be described as a whine/drone when my foot is on the accelerator. I notice it mostly at highways speeds but can begin to hear it at 35+mph. I don't necessarily have to be accelerating for the noise to occur, in other words, its obvious while maintaining a constant speed such as with the cruise engaged. As soon as I disengage cruise or take my foot off the throttle, the noise goes away. I'd appreciate any feedback/thoughts on what is becoming an increasing annoyance. Thanks.

 

Wind noise? Road noise? Or in the case of my accord, probably the cat's shield buzzing/resonating because I keep hitting it on my driveway...

 

It's probably the intake sound.

 

if his resonator is still in his car...i don't think he'll hear much intake sound

i put icebox in with resonator out...i can't hear much with window up....

i'd go with wind and road noise cause by tire....
for me it's 50mi + wind noise is pretty damn loud.

 

It wouldn't be wind, road or tire noise because the noise goes away if he takes the foot off the throttle.

 

I've had this since I got the car in June 2003. It hasn't gotten worse for me.

This was discussed on this forum back then, and if I remember correctly, it was blamed on the fuel pump then? Or maybe the fuel injector was blamed?

I'm not sure if intake noise makes sense to me, because even at idle, the intake is still drawing in air (and the whistling noise is not present). As soon as I hit the accelerator, the noise begins - and the noise is constant (as far as I can tell) through all rpm's.

 

yea mine does the same thing. it's definately an "under the hood " noise. it's like a raspy whine. sounds very cheap. Wish i knew what was causing it. Prolly have to take my intake off, before i bring it in to the dealer, in order for them to diagnose the problem

 

Yes, the intake is still drawing air during idle (the throtte plate is barely open), but the velocity of the air is different when the throttle position is changed. Just picture forming your mouth to blow a whistle. You won't hear anything if you blow very lightly (only enough to exhale), but once you increase the air velocity, you hear the whistle. When in doubt, take it to the dealer for a diagnostic. It's difficult to troubleshoot noise problems over the internet.

 

I have the same whine. I noticed it last weekend when I took a trip. It was a high pitched whine. And like you mentioned, the second I release the throttle, it stopped. Press the throttle and it was there. I have the Enjen CAI installed, not sure if that is the cause. It was more noticeable at higher speeds. I was averaging about 80-85 on that trip. I don't think it's anything major, perhaps it's normal.

 

thanks for the input. if the noise if from the intake, what are my options? i only noticed this recently which would leave me to believe that its not a normal sound. i guess my next step may be the local dealer.

 

Assuming a 200 horsepower Amish TSX would actually be pulled by 200 horses, it's not too surprising that it's noisy.

 

i have the same whine on my 06

 

i have to same whine on my 04 TSX, i had the noise for about 40000 km.
please bring it back to the dealership and let them diagnose the problem
and let me know whats wrong cause my warrenty is out.. my car walked through 93,000km now

 

i just tell people it's my s/c

 

I have the same exact noise coming from the engine compartment area and I think it might be related to the transmission.

It is really noticeable when you're coasting (for example, 65 mph) and you repeatedly depress/release the accelerator. You don't really notice the noise/ringing when depressing the accelerator in Neutral.

I have found this in 4 different TSXs (mine and 3 loaners from each model year) and I think it might be safe to bet that all TSXs exhibit this noise. If all of them have it, the service advisor's will most likely consider it "NORMAL".

Hope someone proves me wrong and reports a fix/tsb.

I got these from another thread:

So the reading list:
annoying engine sound
whistling noise, part duex
whistle
High pitch whistling noise problem with tsx 2004
Whistleing noise...help...
Whistling noise coming from the engine

I read this link: High pitch whistling noise problem with tsx 2004 and it seems the noise is normal.

 

I also get that noise. But I swear I didn't hear it when I got the car, only in the last 2 weeks or so (it's about 8 weeks old now). It was really noticable on the freeway yesterday, almost piercing. I'm planning on calling up the dealership near me and seeing what they say.

 

any good news?

 

It's the intake. Me, personally, I love the sound of that =] Beats listening to music.

 

its not a sucking air kind of sound.. its more of a leaking air or you can discribe it as a lose bolt in the gear box or the axle (i don't know but it sounds like a lose bolt and its hitting something which makes this "whining / ringing noise". the sound only occur at certain rpm and when you're foot is on the gas (lightly only).. if i step my foot on the gas the intake sound will cover that whine noise. I have the K&N cai intake on my car for 2 months now.. and i had the sound with both the stock and k&n intake.

 

I get this noise too. I didn't notice it for the first month or so that I had my car so when I started hearing it I figured something was wrong, but I've brought it to the dealer and driven it with a tech in the car and he says it sounds normal. I thought it was transmission-related since the noise goes away instantly if I depress the clutch, but I can believe that it's intake (after all, when I depress the clutch I release the throttle too) Stock intake with resonator intact.

 

In the "REBUILT ENGINE" thread by Curls we talk about this problem. I've havn't had the chance to visit a dealer to see if this is indeed the problem, but here is conversation I had with Curls.

If anyone is planning to visit the dealer on this issue, please ask them if this could be the cause of the humming noise.

Peter:
Don't mean to high jack this thread, but you did mention you are hearing a hissing sound when stepping on the gas peddle. I have this same problem with my TSX. When I was given a TSX loaner, that car had the same problem too. Is this related to the exhaust leak?

Curls:
My hissing was caused by a round (doughnut) metallic-flex exhast gasket. I believe it would go at the tail end of the header. They replaced it no charge.

Peter:
The hissing sound that I am hearing is some where in the engine area or just behind my navigation console. I guess this could be the same thing. So did the sound stop completely after the fix?

Curls:
Almost exactly what you described, is what I heard.

And yes, completely gone. It was a "flex-braid" type gasket, about 4-5" in diameter (mind you, it was somewhat crushed, so I don't know what the "uninstalled" size might be).

Actually, I found the part in my service manual: It's either the upper or lower gasket for the A-pipe of the exhaust (the pipe right after the header collector). My guess is its the upper gasket as that's where they'd have to have disconnected the exhaust from the car to hoist the engine out.

 

I have 6k miles left on my warranty and am very interested if someone makes any progress on this. I notice the same sound at high speed. At first I thought it only occurred while accelerating at speed, but I've been able to reproduce it while coasting at high speed and revving the engine. I also notice the sound's intensity changes when the outside temp changes. I think it's louder when it's cold outside.

I have an Icebox installed and I'm thinking about putting the stock resonator back in. If I still hear the noise, the exhaust gasket theory is intriguing, as I'm sure temperatures could play a role in the part shrinking and expanding, causing the changes in volume.

 

same here, my car has 6000 km left before my warrenty goes out. I think before my warrenty goes out i'm going to install my intake system to stock and take it back to the dealership and tell them to look at this exhaust gasket problem and ask them to nail down onto it.

 

So I finally took my TSX to the dealer last week. They had it for three days and didn't find the cause of the noise after a good bit of investigation. They claimed that Acura Tech was not familiar with the problem (which I find hard to believe) and that they've not heard the same sound on similar models. I'm at a loss to know what to do next. It's still under warranty so where do I go from here?

 

If it's a repeatable noise, just go for a ride with the service manager or a tech and make them hear the same noise you're hearing.

 

Do you have a radar detector? I have an older Cobra that interferes somehow with my RSX. It's done the same/been worse is some other cars as well.

 

IF you can get a rrecordiing of the noise?? I had the same situation before.. whinning noise only when you acelerate. brought it to the dealer... their finding is that it was a defective tranny. 5000 miles later no more noise.

 

I have what sounds like the same problem on my 04.

Here are my symptoms:

1) No noise while coasting, even at highway speeds. As soon as the accelerator is pushed (even very slightly), the noise returns.

2) The noise is only present when the car is in gear. It's pretty apparent at 70mph while the car is in gear and the accelerator is depressed. If I put the car in neutral (while at ~70mph) and rev the engine to the RPM range where the noise was apparent before, the noise is not present.

These two factors make me believe that the noise is not intake related. The noise seems to only arise when the drivetrain is under load.

I will schedule an appointment to have this checked out soon. I'll post what they say.

 

!!!

5000 miles after a new transmission, there was no more noise? Or it was 5000 more miles until they swapped in the new tranny?

Do you have more details about what was defective?

EDIT: you probably mean that in the 5000 miles since you got the new tranny, the noise has not returned

 

I switched to quieter tires and the noise has definitely gotten much louder, especially on freshly paved roads.

I actually miss my OEM Pilots...well sort of... not really.

 

I'll see if I can get a recording. What was the problem with the tranny?

 

I'd love to hear the feedback you get from the dealer. Although they did work at it, I still felt a little bit like I was getting the runaround i.e. well we can't find it (because it's too much work or costly) so we're sorry but what can we do?

 

My brand new '06 TSX (auto, non-navi) makes exactly the same noise (high pitch whine, but only when the accelerator is pushed). It is driving me nuts. Sadly, this appears to be design defect (or at least a very common problem), based on the number of posts on this thread.

 

Hi

I just bought a TSX recently - and yes, I hear the same whining noise - somewhat like a whistle whenever I drive at a steady speed ..less than 35 mph. I took it to the dealer - he says it's normal/characteristic - well then why didn't I hear it when I first bought the car...makes one wonder. And it has definitely gotten worse over time.


I'm going to take it back to the dealer - it might take a little bit of pushing to get some results.

 

I've never done one. Maybe someone can help.

When driving on the highway going over 35 mph you could hear a humming or whistling noise. This noise usually increases when you press on the gas peddle.
(Or you could add more info)

2004 acceleration noice YES or NO
2005 acceleration noise YES or NO
2006 acceleration noise YES or NO

My goal is to find out if all the cars have this problem or just some. If it is some, then there is hope that we can get this fixed.

 

Hi All

So I went to the dealer's on Sunday (John Eagle Acura - Houston). Asked one of the guys there to take a ride in the car. The one strange thing I noticed was that it was very difficult to get the sound back - this time it was really "well behaved" for lack of a better term. It took about 15-20 minutes of driving back and forth - till the guy finally heard the sound. What surprised me was that when I drive in downtown - the sounds quite noticeable, no - VERY noticeable. Well the main thing is he acknowledged that there was a noise for sure. He talked to his head mech - the guy said it's a design flaw. I'm surprised on two counts - one, if it's a design flaw - why don't we notice it the first time we take it for a test drive? Next - Acura must have heard more complaints about this - how come they have not corrected the design flaw?

Anyways - the verdict was that since the noise wasn't unbearebly bad, and if there truly is a problem - I should wait till it gets loud and consistent. That way they will have a better idea of where to look. For right - it's a design flaw(!!! ).

I'd like to know what the other folks have heard from their dealers.

 

This may hurt my resale value.

 

i have had that noise for more than 50,000 km, it doesn't get worst for sure.. the whining sounds is always there and it's going to hurt the resale value for sure.
my next car won't be an acura no more.

 

Apparently, I have the same problem in my 04 TSX. The only thing is that all you guys say the whiny noise goes away when you take your foot off the pedal, but the whiny noise is still heard while I'm cruising (not foot on the pedal, no foot on the brake). I already took it to the dealers on friday, and one of the head mechanics said it was definately an awkward sound. Well... I'm taking it in tomorrow morning, so I will post the results asap.
