I JUST GOT DONE WITH MY TEST DRIVE, AND I DROVE ON THE FREEWAY AND I WAS DOING ABOUT 75-80 AND I HEARD THIS KINDA NASTY WHISTLE FROMT HE ROOF, DID ANYONE ELSE THAT TEST DROVE IT NOTICE IT?

Hopefully, the moonroof was not fully closed.

No whistle here, but a slight buffeting noise at slower speeds, nothing like the xB though.

I was going around 75 on the freeway today during the test drive, didn't hear anything.

I heard that noise too when I was on the freeway. The sunroof was closed all the way, I made sure. It wasn't too loud and the radio was off. Closing the shades did help get rid of it.

Yes... I heard the wind rustle through the moonroof as well.... When I closed the shade most of it went away....

yes at higher speeds 70+ I hear a little of the wind. But most f the time I'll have my radio on or the top open. I've heard simmular sounds from ever car I've ever riddin in with a sunroof though.

i made sure to hold down on the button to make sure it was closed. and even with the shade closed it was still pretty loud. maybe it was just that car. i just wanted to make sure it wasnt the roof on all of them.

Time to see if Lund or Weathertech will produce moonroof wind deflectors for your tC.

you will get a little wind noise when the sun shade is open at highway speeds. best solution close the sun shade and that whistle your talking about disappears.

tC has one standard.

what he's talking about is when the sunroof is closed. at highway speeds he hears a whistle near the sunroof area. all owners has to do is close the sunshade.

needs a bigger wind deflector :lol:

standard wind deflector looks great. Don't want a dumb looking after market wind deflector to change perfect lines of the tC.

Yea thats what i thought until i clsoed the shade and it still made the noise

Dude, trying to help you out here...

CANNOT reproduce that whistle. Even tried with the moonroof slightly open...nothin.

Ill try again tonight.

haven't noticed it at all on mine. one thing i DID notice was that low-pitched rumble that sort of shakes everything in your head. this may be the buffeting noise erickjam was talkin' about. i think it was in the 30 - 50 mph range. same thing happens in my buddy's jetta when you close the windows at mid-range speeds. anyway to compensate that sort of thing?

The whitsle happenned to me today as i was driving from the airposrt ot my house going about 75 mph. This never happenned to me before, and i thought maybe the strip might ahve came off, but i got out and checked it all, then i thought maybe it was because of the winds. Because today we had some nasty winds blowing and i am wondering if its just due to that, i will find out tomorrow. But then i also thought, maybe it could be that i took out my grill in the front? lol
But seriously it was SUPER LOUD, to the point where my volume is at 30 and its SCREAMING like a BOV. -_-

Yea...I havent heard of any moonroofs making noise, and I am sure if there is any...the warranty covers it...and also...if there is a lil whistle, most likely can just put some 3m tape or foam(done nicely...haha) to stop the noise/dull it down....
most NOISE problems are taken care with 3m or defening(sorry if spellings off) foam.

I use to have this problem where I heard a whistle when cruising on the freeway. I instantly thought it was the sunroof. So I closed the sunshade, that helped a little bit but I still heard a whistle. I hit the air recirculation button and then it was gone.

yeah i had it too, it only happens on really windy day and then doing 70-75mph.. i think it's the crosswinds causing the noise.. but it only happens once in awhile.. test drive another and see if it's quieter :)

and yeah try the recirc button too.. that could totally make sense as well

Mine started doing this on and off after my moonroof started to rattle. After my hatch started to rattle ... after I get a mysterious mid-car rattle :(

Ok, by far i am not a mechanic, but i am not an idiot either...lol

ANYWAY, ok so i did alot of highway driving, and this started this week. SO i ran down the highway and the whislte is there when there is very little wind compared to yesteryday.
So i got the bright idea to open the sunroof all the way and partially and all this stuff. GUES WHAT...the whislte STILL SCREAMING SUPER LOUD. So i was thinking, maybe its not the sunroof, but maybe i changed something that might be throwing the wind curvature off.

Well the only thing i done this week to my car, was totally taking off the front top grill on my car, cause i bought some mesh grill from lowes to make my own custom black one, and i have been driving without one.

SO i was thinking maybe the wind is hitting the front of my car, and creating a noise, and to me it seems like its coming from the top of my car, since its the most sound sensitive area?

MAYBE, i will find out once i put the original grill back on till i get my custom one done.

I'm getting the same whistle.....between 75 and 80 mph the whistle comes.....when I'm going over 80 and gets really loud. wtf is that?

im getting the same whistle sound when going over 65 mph, i had the dealership take a look at it and they told me all they had to do was tighten 1, 2 screws, did it fix the high pitch whistling HELL NO.

Looks like i have to make another trip down there. :tap:

Ihad this issue with mt 05 tc about 10,000 miles into it...brought it in to the dealer and long story short they had to replace the entire sunroof assembly. but not i am wistle free

Did you go to A1 toyota? Thats where I bought my car from.

My car's like me. I can't whistle, nor can the car. ::rotfl::

^^^^ lol wait a few thousand miles :)

I have the whistle too...but the thing is...for some reason it doesnt happen to me every time. i only heard it twice. and i hear it as low as 60mph. it was coming right out of the sunroof in a position right above my head. i pushed it out a bit (while completely closed, and the whistling sound got stronger. then i had the a/c get fresh air from outside, it made the whistling stronger too. It is definitely the sunroof. I noticed that my sunroof is not as flush from the outside anymore as it used too when i bought it. I'll be having my tc service this week and discuss this with the dealership. i hope i get things fixed and let you know what they did.

sad part is that my dealership does not fix anything they couldnt hear, feel, or see. Like my Xa used to have vibration above 80. and they could not drive above 80 and they wouldnt balance the wheels for me. I hope my sunroof would whistle when i get to the dealership this week.

ill keep you guys posted.

Did you guys read my post? Its something around the front bumper throwing off the air curve creating a whistling noise.

So if you messed with your grill, or something came loose, its creating the noise.

It was for me, so I just put the stock grill back on, and no more noise.

I have the stock grill on my car and it still whistles......used to be the whistle would start at around 80 mph....now it starts at 70 mph.....time to go to the dealer....

I have a wistle that comes from the roof area by the mirror. It sounds like a bumble bee is flying around in my headliner. It's only at hightway speeds. I know everything is closed tigthly when it happens too. It drives me nuts so I either roll the windows down and blast the radio to dround it out.

I just recently got this problem. I was driving to Las Vegas and started hearing the whistle in the last half hour of the drive while going 75+ MPH. And this is the 3rd time I've taken my car there. The first 2 times was OK, with no whistling. Damn I hope someone figures out how to fix this problem cuz i really doubt the dealership will fix it if they cant hear it.

Yeah. I told the dealer about it once. Could not replicate at all. Just a waste of time... I thought about filling a pool with WD40 and driving my car into it. That mite get rid of all the noises and squeaks from my car.

I had the whistle in the sunroof. In my case you could see from the outside that the sunroof was not closing flush or even with the rear moonroof, creating a small gap between the glass and the rubber seal at the very rear of the front sunroof.

I would notice the whistle most when there was a strong cross wind or if I opened and then shut the sunroof while at highway speeds (>60mph). I would usually be ok if the sunroof was shut prior to driving on the highway. Shutting the screen would dampen, but not eliminate the noise.

Here's what to do:
1: if it happens while driving, crack one of your windows and then (re)shut the sunroof. Then roll your window back up. This will cause the sunroof to shut a little tighter. If this doesn't help just reach out of the car and push the sunroof down with you're hand. -It's only a temp solution.

2: When you have some time to look at the sunroof, there should be a screw on each side of the sunroof towards the rear. These are # 25 Torx screws. These screws serve as an adjustment to allow about 0.25" of up/down movement. With the sunroof in the up (not back) position, loosen these screws. Now with the screws loosened, hold down on the sunroof and (re)tighten the screws fairly tightly. This should adjust the sunroof to the tightest position and hopefully solve the whistle problem.

Note: There are actually 3 screws on each side, adjusting the frontmost screws ( still on the sunroof) may help if you are having problems with the wind screen not closing all the way.


If you're like me this may come back a couple times after a few thousand miles. Perhaps some superglue might prevent the sunroof from reverting to its noisy poisition.

I just found out that in addition to having to initialize the driver and passenger side windows the sunroof can be (needs to be) initialized too. The instructions were in the FAQ (http://home.cfl.rr.com/icdedppl/faq.html#c14), but I missed them the first time through.

I was able to reinitialize my sunroof and got the extra 1/8th of an inch of closure I needed to resolve the problem permanently. This is probably easier than adjusting the glass (especially for those without a good torx set).

So if you're sunroof has a whistle, don't pass up this basic step.

Sometimes our tC will make very loud wind noise at highway spped. I have to open and reClose the Roof to make it go away, sometimes.

The Roof is one of the Weak Links in a tC IMHO. The Floor Mats Suck also, but for a $16,500 Car you can't expect Perfection.

My S2000 has a lot of wind Noise also, but I guess you should expect that with a Light Weight Roadster/Convertable. At least the Scion has a decent Stereo to help drown out the Wind Noise.

I should have captured some pics from the outside that show the sunroof not closing all the way. Does your glass sunroof panel close flush with the other glass panels?

Sometimes we also have to hold down the wind deflector to get the roof to shut.

Metro Toyota in Kalamazoo has tried to fix our Sunroof Twice and the Problem just returns.

It must be a design flaw and we will have to live with it.

I'll take a look outside to see how far off the rear of the roof is next time she starts to sing.

When i took my car in to get serviced, they gave me a free car wash. When i was driving home i noticed a LOUD A$$ noise coming from the sunroof. It turns out that the air-dry system that they use from the car wash ripped off the weather stripping from where the windshield and sunroof meet. I got it fixed, but i still do hear a noise. Not as loud as it was before though.

My moonroof started whisteling about 1000 miles ago. It whisteles at about 70mph. I tried hitting the air recirculation button, and that made the volume of the whistle decrease. I opened the window, opened the moonroof, then closed it all the way, holding the button of 5 seconds to reinitialize the system, closed the window, and that seemed to reduce the soiund. I just took my car into the dealer for the 30,000 mile maintenance., and mentioned the noise to the them, sugguesting that the sunroof needed to be tightened on it's tracks. The determined that they could hear the noise, but would need to investigate further, to the tune of $80 as it would not be covered by Toyota because "Toyota only covers the first 12 months of ownership for adjustments to be made under warrantee" (and I bought the car from the same dealership 4/05). Is this true? This seems like it should be covered. I already brought the car in last summer because my sunroof wouldn't close, and the dealership put grease on the tracks, and I didn't get charged for that.

i think its not a good idea to drive highway speeds with the sunroof open, when you look up it shakes considerably, especially on windy days, perhaps this may be causing the problem of whistling. I must say the sunroof is maybe the only thing i dont particularly like about the tc.

Not only is it not a good idea to drive highway speeds with the sunroof open, the manual specifically says not to. Any speeds over 50-55 mph I believe were the limits set and I know if I get near 50, I can hear the wind resistance.

Yeah, it whistles when it is closed. I know not to open it at speed.

Mine dooes not whistle, I honetly am shocked, only thing in my car that does not make a noise it shouldnt.

PFR,

I had the same problem (as i posted previously). It took me a while to have it fixed because everytime i brought it to the dealership for an oil change, i was in a hurry to leave and they needed to test the car.

To cut the story short, it took me till my 30K mile check up before i let them do a diagnostic for my Tc. i know your warranty should cover you within 3 years or 36K miles.

I had to bring my car back 4 times before it finally got fixed. In their first attempt they did the same thing "re-lube" the tracks...didnt work. second, they adjusted the motor...still was whistling, but a little slighter. On my third attempt they told me to come but they cancelled. So technically, i had three attempts...one more it would be qualified as a lemon.

I had no intentions of filing a lemon, i love the Tc. But as I spoke to the service guy saying i was tired of it, going back for a 4th time, i asked "can you really fix this? becuase i think its helpless" probably thinking i would lemon the car, (or maybe not) he said for me to come in and he would replace the whole assembly...which he did. the assembly looks different, but as long as the whistle is gone.

it was good as new. it closed so tight that when you were on the freeway and close it, your ears would pop (just like when it was new).

So i think you have the right to have that fixed, cause you paid for the warranty. and i think only by replacing it would it get fixed. so good luck

Um, your warranty covers everything 3 years/36k miles. Sounds like another dealer that's lying to you. Seems to be common place among Toyota dealers to lie to customers over and over about warranty. Find another dealer.

Yes for 06 and up, they changed the drive motor and other components of the sunroof. That's why replacing it all, fixed the noise.

have there been any update son this topic. I am experiencing the same issue. However, when I ask some of my friends (2 of them 05 tC owners and 1 of them has an 06 tC) only my friend who has the 06 experiences the same problem.
Any suggestions?

Someone found a fix too...

I tried that before I brought it to the dealer. It didn't help. There seems to be something else wrong. The moonroof motor itself seems to be too weak to make the moonroof seal properly. In fact, when I shut the driver's door when stepping out of the car, I can see the sunroof jump slightly, due to the pressure inside the car.
I have a appointment to finally get the entire roof assembly replaced... we will see if they try and charge me for it.

If it's still under warranty I don't see why they would charge? Don't forget if they're keeping it overnight to have them get you a donor car. You shouldn't have to pay for your car too, just gas.

Thank you! My car was whistling for 5,000 miles and the dealership told me I would have to replace the whole assembly for $2000. Its actually in the owners manual. I'm deffinately reporting the dealership. Thanks again for your post. I love my car again. :bow:

A lot of the tC's came into the shop I used to work at for the moon roof whistle. Sometimes the weatherstrip was coming off ,others it was just a windy day, sometimes it needed a whole new roof. There hasn't been any recall on it, you do have to understand the the top half of the car is 4 pieces of glass, so of course it isn't going to be as quite as a car with a windshield, metal, and a back window! Good luck to ya, hopefully you can get it figured out, either way your car should still be under warranty!

Yes, I have the solution to your whistle. I too had a whistle. Tell your dealer to tighten your sunroof cable. Whistle gone.
