Welcome to the forum. Have you had the sunroof drain hose recall done?lornix said:Our '08 is going in for servicing next week to get the seals checked on the sun roofs. Never had a problem until this winter when there was a lot of snow and ice. Suddenly we have water leaking into the cab in 2 places.
It could also be air pressure forcing the sunroof up a little, I have noticed this once, but not to the extent you guys are talking about. I have the wind/sun shield on mine and that may be what is keeping it from being noisey.k2 said:I noticed the same thing on my 08' SLT. Some of my observations. I only noticed this since the weather started getting cooler in the fall. I did not hear this noise in the summer. Doesn't happen all the time when it's cool, but when it does happen, I can make it happen more by turning the wheel side to side quickly while in motion (at lowspeed) or by placing my palm on the glass from inside, and applying slight pressure. My thought is the roof is flexing, and causing the sunroof seal to squeak against it. I had the dealership take a look at it, and they torqued all the sunroof bolts to spec, but it's still happening ... sometimes. I dropped it off at the dealership today to get the front license bracket removed, and the holes filled, and mentioned that the sunroof problem is still there. Not sure what they'll find. This is the front sunroof that makes the noise, and I find if very annoying also. Makes me wonder if there isn't something that be applied to the seal to make it not squeak, like silicone spray, or other. Hard to describe, combination leaf flap, and squeak/rattle.
