I don't know about you guys but does your I4 seem noisy during start up and when driving at low speeds? Kind of like a hair dryer whine as the rpm's go up? I originally chalked it up to a break in issue but after 12K miles its still the same. I recently asked the dealer about this and they said they had about 15 or so people mention this to them and they called Honda. It is a characteristic of the engine they were told.

This new 4 banger could sound so much better especially in a car as nice as the new Accord. I think Honda missed the boat on this one.

The car is in the shop now for a pop that happens when the engine idles down from a higher rpm. As a comparison the Civic loaner they provided has a much quieter engine but has more road noise. Go figure.

Not sure if your is different than what i hear, but i am very impressed with Honda K24 engine.
Nice broad torque curve. Maybe your hearing tranny gears whine, in the lower gears ?
That's about all I hear as a whine, until you get on it but then its engine roar, especially above 4500 rpm.
Nothing abnormal in my opinion.

I have a 08 coupe and have noticed it also. The base LX/LXP cars are more noticeable due to the missing hood insulater. I also have a 06 LX sedan and the engine is smoother and quieter it seems. The 190 hp engines also have special exhaust system to get the 190 hp vs 177 which I find also louder than the average car. ANC takes care of that noise at higher speeds. I'm thinking Honda engineered the car this way to give it more of a sportier sound /image. I'm not sure it works in the sedan application. More of a coupe thing..............

No doubt it is a very driveable engine that sounds much better in the upper rpm range. You can rev the engine in neutral an get the same whine sound coming through so its not the tranny gears. I was thinking the balance shaft or torque convertor. Anyway, low speed driving around town in stop and go or parking lots its more noticeable due to less road noise. Not a refined sound in my opinion.

its funny I have to same issue the "whine" I was beginning to think it was the alternator belt being too tight and causing the broblem,.....wearing in the bearings....

Yeah I hear it too and I think it's normal at low RPMs, I wouldn't be too concern with it since it seems like everyone hears the same thing.

It sounds like a toy car right? If so, it's normal :D

I hear it too and just think it is interesting. this is my first car made after 1999 so i really don't know much about cars and i never tried to think of what it was. I just figured that is how this car is supposed to sound! :)

important question though, since we have a special exhaust system on this car that gets it from 177 horsepower to 190, what happens when various parts of the exhaust (including the exaust tip) wear out? do we have to get it replaced oem?

I can't really relate to the whining you guys hear, maybe its because I upgraded from an 02 civic (which took 5 seconds to realize the gas pedal's floored), but I have to admit, I love the engine sound during all stages of drive, particularly when I reach 4500 rpm :D

can't say i notice the whine, myself... and i'm usually one to pick out every sound that seems out of place...

It's not the steering when you're going straight...

all i know is i replaced my power steering pump after 2 weeks of having the car(it was whining while CRUISING STRAIGHT with the rpm around 2000).... and just last week had the whole power steering rack replaced because it was leaking...which made it whine when turning left...

but no... its not the steering rack, i guess i dont know better...

yea i noticed that sound too kinda sounds like an RC car right?

this is my first new car.. ive noticed it but i thought it was part of the break in process... anyone know what it is? im about to buy some aftermarket hood dampener to try to kill some of the noise..

I know I really like how Honda engineered the power steering pump to disengage when the wheels are staight...

lol you cracked me up :lmao: Thanks for the morning laugh :biggrin:

I meant the noise. Usually you get the noise when you turn the wheel all the way left or right, that's when you need to flush/fill the steering fluid. You don't get steering noise when going straight...

Right, that was next thing I was going to suggest, there hearing the PS pump. mine does make some noise as all due but nothing abnormal, maybe some have pump issues as that will make a whine noise if not right.

From Hondas documentation:

In the Accord LX-S Coupe and all EX and EX-L models, an even more powerful inline four-cylinder engine is standard. With a high-flow muffler and reprogrammed Powertrain Control Module (PCM), the 2.4-liter inline four-cylinder generates 190 horsepower at 7000 rpm and 162 lb-ft. of torque at 4400 rpm. Though it's by far the most powerful four-cylinder engine ever offered in a North American Accord, this powerplant is designed to run on regular unleaded fuel, and also meets PZEV (AT only) or ULEV-2 emissions standards.*

X2. No whine heard on my end.

Just make sure you replace with same OEM spec as EX models. I think the EX 190 exhaust is also larger DIA than the LX 177hp one. If you replace with a 3rd party aftermarket type muffler it will depend on quality and size of system used.

i know i gotta stop getting off topic but damn thats a long tongue! have you ever put peanut butter on your nuts and have that dog lick it off?? :naughty:

Getting off topic again...

But I wonder what Honda did different to the 2009 TSX to get 201hp out of that engine. I mean it's basically the same engine we have in our I4s right?

they took out the chip

If I remember right, the CR went up from honda's 10.5>11.0 and its programed for 91 premium gas. the exhaust is improved to, more free flowing they say.
The basic engine is very similar and uses many of the same parts as 8th gen 2.4L from what info I have read.

I did not mention this before since I was curious if it would come up but the PS pump has been replaced twice. I think they did it to be doing something but the noise is still there. Like I said not very refined NVH. Maybe we will get a TSB in a few months.

I have a few issues with my 08 I4 Accord, but the sound and feel of the 190HP I4 is not one of them. I love taking it to redline in 2nd gear and makes no abnormal noises.

For me the 190HP motor in the Accord is a perfect match and I seldom wish for more power.

I do agree with you about the 190 being fine but have you test drove the v6?

That beast has that instant power that I miss when getting on the freeway; but other than that I'm fine with the I4.

My other car is a 450HP 2006 Corvette. I needed a nice 4 door sedan for work hence my 08 Accord I4 A5 EX-L. When I want to play with the "kids" I take the vette out. Plus it gets almost 29 MPG on the highway so I don't feel quilty when I'm out having fun.

so wait!??? i've been putting in premium fuel for nothing??!? i just figured it would use premium fuel 'cause i came out of and rsx type s and even that used premium so i assumed the accord would...:dunno:

hahaha. yup, all accords only require regular, Acuras tend to use a compression ratio that requires higher octane to prevent pre-ignition

AHAHA what a foo I am!!!!!!!!!! jeez.. gas has been 3.95ish and finally up to 4.19 for premium and that's the cheapest price i've found(chevron) 60+ bucks for a fill For The Lose!!!!!!

Not a fool at all. Live and learn, my friend.

To be honest... I never REALLY hear the engine. Usually my music outpowers anything the engine has to say. Music is a good answer to rattles as well if you ask me, and eventually you'll go deaf and nothing will matter to you. :D

wait u mean your salesman didnt tell u that ...he told me as if that fact would sway me to purchase the accord rather than something else:lmao:

LOVE the whirling whining sound - reminds me of a turbo, LOL

:dunno:

I hear the whine noise also. My 08 Accord LX with the 2.4L 177HP is 3 weeks old, test drove and drove home during a down pour, didn't hear the quite noticeable whine until the next day. Whine volume can be said to be constant, but the pitch tracks either or both the RPM and the velocity from 1 to 45MPH. The Transmission is auto, whine is present in both acceleration and deceleration, but the whine is now less noticeable (soft) after 280 miles, sometimes almost gone.

Chief Honda mechanic also heard the soft whine after the evening class for new car owners, said no need to be alarmed, bring it in if I wish, probably due to some belt.

As I drove home this evening, I could have sworn that the speed bump affects the present of the soft whine, like the noise bounces with the car.

Since I have not read anything to raise the alarm here, I am going to drive it more to gather additional data before using up that freebie offered by the chief mechanic.

haha the noise bounces with the car? I have yet to hear this noise, its probably nothing...but it might be alive? I mean, if it bounces with the car...

3.95 for regular? OMG! I wish.. We have a main port of entry here in Ft Lauderdale and damn gas is still 4.12 avg. for regular.. Id take 3.95 and run with it... On a lighter note.. Diesel is 4.79 a gallon...:thumbsdow

I too had the power steering rack replaced because of a leak. The whining sound was really bad when the fluid was low due to the leak. So when it kept whining after it was fixed I thought it was the power steering pump. So they gave me a new one and the car still whines, whether it is in gear or not. It drives me crazy. I wish honda would do a recall and fix it. Why is this whining sound present on some but not all? Mine is an accord coupe LX-S (4cyl), has 4K miles.

I have been doing the same as you =(. And here I am complaining about $3.13 for premium at Shell.

Those gas prices were from last year...

Going from a 08 coupe to a 09 sedan I noticed both cars had that whine. I took my 09 in the dealer around 4 months ago and they replaced the PS pump. No difference in noise, but the head tech swears the pump was bad- I think they were fishing. Anyway, I do believe this is a normal sound from all gen8 K24'S. Interesting, I had no noise with my 06 sedan with the same engine.

I have had whining sound from day one too. Not a PS for sure as the whine is present while driving straight. Today was reviewing Factory Direct forum and found this TSB 09-084 posted 2 weeks ago.
08-09 engine whine 09-084 (http://www.driveaccord.net/forums/showthread.php?t=40510).
Released on Nov 11, 2009.
There is an embedded sound file inside PDF document where you can listen to "turbo charger like" whining sound that affected engine makes.

Oil pump is to blame and needs to be replaced...

Have anyone already got a whine fixed under this TSB?

would a performance intake cancel out the sound? i dont know much about cars, so would it sound better? i have ex-l with that active noise cancelation. what the hell is that? is that even needed? could i take it out and sell it? i dont know either what the lx series engine sounds like but i would rather have that nice vroom sound than that weird "zzzzzzzzz" humming sound the engine makes. maybe thats what it is...

i'd say wait till it gets warmer (if your up north) before you take it in and get that serviced... i asked my dealer... and he said it should really cause any problems as of right now, but you should get it checked out as soon as you can... i honestly can't tell if its just air being sucked in noise or an actual whine... lol

i have this whine and its annoying
it turned out to be the power steering oil is low
and for some reason it allows get low

That TBS is not same noise , PS does make constant noise the oil pump is a turbo type pitch changing noise.
If your PS needs refilling a lot or at all, bring it in to dealer. I forget exact TBS but its known issue on a seal if i remember right .
