Sunroof noise

[luvsanmls]

I have had sunroof noise since day one . I've taken it to the dealer several times and they put some sort of yellow looking powder on it , that looked awful . The noise would stop for a little while then would start back . It looked so bad I wouldn't open the cover on the inside . I would like to hear from others that has had same problem .

What kind of noise? Wind noise when open? Squeaks when closed?
There was a TSB on squeak/ticking noises a while back (TSB #09-BD-11). The TSB fix is to use 3M dry silicone spray lubricant on the rubber weatherstripping/seal at the back edge of the sunroof opening.

The TSB "test" to see if this is the source of noise is:
* sunroof closed completely, ceiling panel open.
* push upwards on the glass along the back edge, mid-way between the sides, to see if this causes the noise.

If this test finds the noise source, the TSB suggests the silicone spray. Tilt the sunroof as far as possible to get access to the rear seal (on the car, not on the sunroof glass itself) and spray it. Wipe off any overspray. Let the car air out a bit since silicone spray does have a little smell to it.

Yes that is the noise . Sunroof is closed and sitting still and I can push up and down on it to get the sound I hear when driving . I guess that is what they are spraying on it but it only lasts a short while and turns a yellowish color .

Geez... Looks like the informative threads have helped. And identified something of a design issue I have not heard of since my 1986 Acura Legend. You would think they would not make the same mistakes. I wonder if that is why they supply the sunroof air deflector? At speed it might help reduce the glass panel flutter from the back while closed. In the 1986 Acura, that was exactly the fix.

It is more than just the seal. The front edge of the roof actually lifts up at speeds above 70-80 mph thus causing the noise. Opening and closing the roof at lower speeds minimizes the problem for a while. It appears there isn't enough pull down force on the roof when it is closed.

Do you have a wind deflector? This might help.

There are small bolts at each corner of the inside of the glass frame. These bolts adjust the roof up and down so it fits properly when closed. If they are loose then the symptoms described above will occur. The bolts are not easily seen, they are covered by black trim.

If these bolts need adjustment to stop the noise then why don't my local service dept . know this ? I have been dealing with this issue from day one . And as for getting a deflector to stop the noise , I think they should furnish this without me having to pay for it .

Your dealer's service department personnel is lacking proper training. A deflector is not the solution, its a band-aid.
