My first contribution...possible DIY fix for sunroof creak TSB

So I'm new here, but not to auto forums in general. Just picked up a CPO'd 2011 Limited. I've been reading about the creaking panoramic roof especially behind the front passenger seat because it was driving me nuts.

I was thinking about having the dealer complete the service bulletin, but was tentative about them doing anything with the headliner. Figured I'd share my fix which should be easy enough for anyone to try.

1. Loosen the torx bolt where the creak is most pronounced. I tested this by continually pushing up on the glass and identified the forward-most bolt on the passenger side. I believe it's a T20.

2. The roof should stay in place with just one bolt loose but if you feel it drops or is out of place, there are tolerances floating around the forum somewhere on the gaps that should exist.

3. The creak came from where the metal bracket that hold the torx bolt meets the body (sheet metal). A little white lithium grease sprayed with a needle-type extension from the spray can between the two did the trick! I retightened the bolt and viola!

On reading other's posts about it, this solution makes sense - one member reported a tech putting a shim in, and while he didn't know where, it was probably between the torx bracket and body. Others have had the TSB done where the whole frame was replaced. One forum member also tried to put in washers in case the torx bolt had bottomed out and wasn't tight enough.

Sorry I don't have photos but if you take a look at either side of the panoramic roof, you can't miss the bolts. Just remember to spray BEHIND the bracket. A little goes a long way.

Hope it helps...

Has this fix proved to be a permanent fix for you? I have a rattle coming from the same general area on my 2014 JGC. It's a metallic clicking/rattling coming from the sunroof on the passenger side between the b and c pillars. I'm thinking about trying this.

Re: My first contribution...possible DIY fix for sunroof creak TSB

So far so good. I did this on Wednesday and haven't heard it since. For the time it takes, less than 5 minutes, it's a good "first tier" fix. The space behind the bracket is the problem area so other more permanent fixes are doable. I was considering a very thin nylon washer cut in half...There is enough play after the torx bolt is loose where you could easily slide it behind the bracket.

Re: My first contribution...possible DIY fix for sunroof creak TSB

Thanks. I think even as a first tier fix, this is pretty valuable for diagnostic purposes. If it works for a while before rattling again, at least it rules out having to replace the entire frame rail with the attendant risk of future leaks. One further question. Do you think you can get away with not loosening the torx screws? I was thinking about squirting a bead of lubricant across the top of the backside of the bracket and letting a combination of gravity and body movement draw the lube down the back of the bracket. Possible or too tight? Thanks, again.

I think it may be too tight. It might also lead you to spray more than you need with the hopes of making sure enough can get in there. I will say that when I loosened the one bolt, the roof "barely" moved. The bracket loosens just enough to give it one quick spray. I checked the gap and overall level from the outside once I retightened just to be sure, but it (the roof) really didn't move one bit.

Allowing one corner to move can bind another. There is a pretty strick adjustment procedure for setting the glass height.

Well, I tried the fix, albeit without loosening the brackets and it didn't make any difference. I was a little spooked about misalignment and didn't want to do anything further lest I make it worse. Service tech finally heard the rattle on a test drive. Dealer is replacing the sunroof tray.

Re: My first contribution...possible DIY fix for sunroof creak TSB

I hear you. At least the problem is being addressed. Unfortunately, I've always had that gene encoded into my DNA that can't leave things alone...at least my "success" percentage is going up as I get older!

On an update almost a month later, the pano roof is still quiet and I have also fixed an annoying headrest rattle. Unlike others, I've never minded rattles, squeaks, etc. as long as I can fix some of the most annoying ones myself. I've owned cars from many manufacturers and they ALL do it. New, used, whatever...doesn't matter. The only real fix to eliminate all rattles is to turn up the radio!

I've got a rattle in my passenger headrest. What was the fix for this?

Also, my pano roof rattle seems to come from the front passenger side. I tightened down the torx screws up front, and that lessened the severity of the rattle to only when the car is hot inside from sitting in the sun. Still trying to track down a solution as I'm out of warranty.
