I did a little poking around on google and really couldn't come up with anything other than some people that had this problem with other vehicles were able to get rid of it by using a different type of air filter (i.e k&n). Makes sense if you think about it..... If the whistle is coming from the air duct, making a small change in flow could get rid of it (...or make it worse...). If it's at the throttle body I'm not sure if using a different filter would have any effect.
I'll keep listening.

Stock intakes usually don't whistle tho, but I haven't heard an '09.

If it's any help it looks like it's same size air filter as the one my 2000 Frontier V6 used. You may want to measure yours and compare it against that part number.
Fortunately, I don't have this whistle with my '09.

"Normal" not good enough for me, for a car that's over $40k MSRP... On second thought, should not have to endure whistling from any brand new car, AT ANY PRICE! It's really a shame because I love the car. I hope Nissan eventually makes good on it as I won't just accept the noise. Giving my dealer one more shot, then back to Consumer affairs, BBB, then attorney if necessary...
Anyone have an update on their end - any luck remedying the sound?

You're so right, it's not acceptable for any brand new vehicle to make this noise, especially one this expensive. I think I first noticed it at around 1,200 miles but I wasn't really concerned about it because I figured when I took it in for the first oil change, they'd fix it for me. That didn't happen and they had the nerve at the dealer to downplay the problem! I left it ALL DAY for them to fix it along with a detailed description of the problem. On my invoice, the service advisor stated: Cannot duplicate concern, operating as designed. Unbelieveable!
At least now they admit there is a problem since I drove another Murano SL, which didn't make the noise. My service advisor at the dealer was supposed to call me back after the mechanics (technicians) consulted with the help-line about my problem but hasn't called yet...hmmm...I don't think they know how to fix it.
If they ever do fix it, I'll certainly post it for the rest of you.
Good luck to those of you in my company...and to those who haven't heard the noise on your 09 Murano, listen carefully with your windows down!

They said they were on the phone with engineering all day and are ordering a new front exhaust tube to see if this helps - Well, at least they are trying something. I asked, if it's the exhaust, why would turning overdrive off stop the sound? Answer: This is what they came up with in a discussion with Nissan engineering. They either have no idea how to fix it OR (as I suspect) it's too expensive or involved (trans. or engine) to fix for such a "minimal problem" so they basically keep shrugging their shoulders. I'll let you know if this part helps (or masks) the problem.
Just curious - Mine was driven 40+ miles from another dealer prior to purchase. Anyone else?
I'm wondering if it was mistreated prior which I hear could damage CVT and/or effect the pistons...

I haven't tried the O/D OFF thing. I refuse to drive around like that due to the fuel waste. Oil rose $17/barrell in the last two days...if it keeps up at this rate, we'll be paying $5/gallon within the next few weeks! Grrrrrrrrrrrr!!
My squealing Murano only had 20 miles on it when I bought it. I figured all the guys (salesmen and mechanics) took the new rides out for a spin when they first arrived. Maybe they did abuse them, what do they care?! Maybe this is simply a design flaw...in any case...it must be fixed!
This is not what I expected when I forked over so much coin for a ride!

| I too feel your pain. I purchased a 09' Murano (SE AWD) about two months ago. It had less than 5 miles on it when I purchased it. Maybe a week after the purchase I too noticed the squilling. It happens whenever I press the accelerator lightly to maintain speed. Fortunately, I can't really hear it when the windows are up, but if they are down it drives me nuts. I have been to the dealership twice. The first time, the guy said that he couldn't hear it. So I came back a second time to try and get another guy . . . same guy. So we drove around again. Again, he couldn't hear it. So, for my own edification, he let me test drive a LE. I was able to reproduce the sound but the squill occurred over a much shorter range of accelleration and was not nearly as loud as my own vehicle. At that point I knew it was a model-wide problem and the road to getting it fixed was going to be uphill. At any rate, that's where I stand. I don't feel like doing a dance with nissan to repair it (If a repair is even feasible). I appreciate those of you who do. Please keep us updated. |
Welcome to NICOclub, glad to have you here in the Murano forum! Sorry to hear about your troubles, stay tuned and check for new posts here. I am sure if enough people have the same problem, sooner or later there will be a solution. I have an '09 LE, and I have not experienced this, and I hope I don't.

I did hear though that the K&N filter for the 07 fits the 09. No first hand experience, so check it out before buying one
BTW, my kid replaced his o8 Altima intake with a Fujita, loves the sound and claims the mpg is a bit better with a few more horses!

Welcome to NICOclub! We hope you enjoy the Murano forum! Yes, the '09 Murano uses the same K&N air filter as the '07 Murano! Check out my post here:

My wife and I just purchased a 2009 Nissan Murano LE. We are having the same issue as you all. I did a search on Yahoo for "Nissan Murano Air Intake Issue" and this thread immediately came up. While I am sad that all of us are having this issue, I was at least happy to find a thread where people are discussing it. I have read through this thread and figured I would join this group also (I am also a member at MY350z.com) and keep you guys up to date where we are. We have been to 2 different dealerships and they have both agreed that the noise is coming from lower RPMs...i.e....not slamming on the gas pedal, which I am sure you all are experiencing too. We also have a lemon law here in North Carolina and we are in the process of getting three documented times of them trying to fix it. As soon as we do, we have already discussed with a lawyer the issue and they will fight this for free on our behalf (of course they will get paid nicely by Nissan when it's all said and done). I will give an update as soon as possible. In the meantime, nobody should just be "accepting" that this is an issue on a lot of the Muranos. For the MSRP of our LE (approx $41k), this is UNACCEPTABLE and we are going to make sure that this issue gets resolved. We hope that we can end up getting another LE which does not have this issue because in our opinion, there is no other crossover / SUV out there which we would rather drive. I'll keep you all posted. Take care.

My wife received a call today from our Nissan dealer in Charlotte and it seems that all of our complaints are starting to work. She was informed that another Murano driver had came in and they tried this "fix" which the engineering group had came up with to correct the noise and it worked. We are taking it in this week to have the "fix" done and I'll keep you posted if it works

I'll make note of it and post early next week. I can't hear it with the windows up and it's supposed to rain all weekend. I think it's between 1000 and 1500 rpm.
Post Title: Re: Air intake suction whistling (Bunshaw)
Posted by: brainguyus at 10:54 AM 9/14/2008
1,200 rpm is the magic number. It occurs at almost a coasting accelleration and it's within a very narrow rpm range. The whistle is very high frequency and barely audible....so much so that unless it gets worse (or dogs start chasing me 
) I'm not concerned about it at this point.

Just curious....was it gum buildup at the butterfly valve?

YUDAMAN!!! 1. Is there a TSB for this yet? My Nissan Shop will not do the fix without some kind of TSB. Believe me I've tried.
2. When they replace the throttle body is it with a redesigned part? Are they replacing the part with the exact same part that is going to start whistling again after 2 months? Was it a problem with the original installation of the part (ie. the part was installed improperly)?
I notice this problem the most when the windows are open and spring is quickly approaching. I really would like to get this problem rectified and I have a lot of people who are wondering the same things as me. Please Nissan, some more info.

For the record, the throttle body does NOT have to be replaced. Here is the fix description...straight from Nissan:
NTB08104
IF YOU CONFIRM A whistle noise coming from the engine during light acceleration, ACTIONS Unbolt but do not remove the electric throttle control actuator. Replace the actuator gasket. Reposition the actuator on the manifold and secure following the instructions in this Service Procedure. NOTE: The repair of this issue, if it should occur, is the repositioning of the actuator not the replacement of the gasket. The gasket is replaced because the actuator is being unbolted from the manifold.

I had an 04 Murano before the 09 and loved it, no problems. I had two Maxima's before the Murano's. My last four vehicles have been new Nissans. You would have thought that Nissan would take care of a very loyal Nissan customer. This event has spoiled the love. At this point I don't know if I'll ever buy another Nissan.

As far as the TSB is concerned, it is confirmed. The adjustment was made to the throttle body and I have had no whistling since. Thank you Nissan.

You might want to check these out, and see if you can find the 09. I just bought one for my 05 and it was sealed Brand New!! This is the K&N equivalent, Fram Airhog and $8.98, yes Eight Dollars and ninety eight cents!! you can not loose!!

I too have the same "whistling" noise everyone is talking about.
They are currently ordering a gasket for something but I can't remember what part it was.
When I get the Murano back tonight I will list the info on the repair order so others with this issue can hopefully get a reprieve.

It may help all to know that the part that was ordered is called a "THROTTLE GASKET."
The mechanic diagnosed it immediately and I received a call back from the dealership service center letting me know that the part would be ordered and ready to be installed sometime next week.
I will report back with an update as soon as the repair has been completed.
Hope this helps all of you searching for answers.
From speaking with the service advisor, the mechanic also did NOT think it was normal and apparently thought the current gasket was faulty.

The gasket is not faulty. They have to replace it when unbolt/adjust the TB (raising it up while tightening it again). Service Bulletin NTB08104 describes it well for them. I just had it done on my Murano - worked - it's incredible driving without that noise!

My '09 Murano is getting the throttle gasket replaced/adjusted this week.
How long did the repair take for you?

This issue has CONSUMED me ever since I took home my 2009 LE back in May 2008. I have taken it to the dealers twice with the TSB info to fix it.
First time after the fix, the noise (on a scale of 1 to 10), went from a 10 down to a 4. This was WAY better than before where it was almost unbearable hearing that high-pitched dog whistle.
About 6 months later...I took it back because the whistle, although much improved was still there. They did the TSB fix by adjusting the throttle body and replacing the gasket (don't think they replaced the gasket the first time). This time, the whistle went down from a 4 to a 1 or 2. I may be a freak, but if it is real quiet and I get the RPM band in exactly the right spot with just the right amount of gas applied, I still hear it. It is much more faint and I'm probably only one out of 20 people that could hear it (because I've tuned my ear into to), but it is definitely still there.
I am ok with it where it is...but the fact of the matter is that something in the engineering design of the TB is flawed and Nissan let this slide through the cracks. I suppose if I pushed hard enough, I could get a whole new TB installed, but I don't think its worth the fight at this point considering all I had to go through just to convince them to do the TSB fix twice.
