True lol

Pano roofs are always noisy, I like the look of them but I avoid them like the plague. On top of that, pano roofs place extra weight on the roof, that is the last place one would want to add weight, on top of the car's center of gravity.

I've had a handful of various rental cars with them that don't ever seem to have the issue, but they are usually less than a year old.

I think it says something that BMW has never even attempted to put on in.

The BMW x3 and X5 have a lot of pano roof noise and rattle issues.

Was not aware they put them in their SUVs. I know they don't exist in their sedans.

Interestingly enough, a Grand Cherokee built on the ML Chassis seems solid as a rock when driving it (but again, new).

Anyone got pics where to lube and what lube to use? So we know what to do without going to $$$ hungry dealer service? That info would help many people here. I have pano roof but didn't hear any noises yet.

Got mine back, sans rattling and creaking noises. I got the part #s around here somewhere, will post them up...

Or not. all I have is the following:
"Able to isolate noise to the left side of roof. Lowered head liner included the removal of A,B, and C-Pillars . Removed all hardware holding head liner in place. When tested again, noise was produced by the movement between sunroof frame and body."

"Applied Thread Lock to all screw hold frame and secured frame to vehicle. With headliner still out, road tested again and noise was no longer present. Head liner was installed."

Um. It took one tech most of the day to tear the top half of the car apart and two guys on a test drive to isolate the noise. Best of luck...

Mine popped the other day, sounded like someone shot at the glass. I did it when it was colder. Should I be concerned? Where do that sound come from? Love the car tho id never buy anything else, unless its E63 AMG lol

Just got a 2011 E350 with the pano and have the loud popping noise. Is there a DIY somewhere on how to remove the headliner and get at the bolts? I've searched and can't can't seem to find it. I think there was one on the W211. The W212 noise seems to be worse than the W211.

I'd like to know this too.

Oh here's the info for the headliner courtesy of Konigstiger:

It's couple pages. Wonder how long it'll really take.

Thanks for posting the link. Wow, it's a bit more involved than I anticipated.

I have the same problem with my 2014 GL450. Roof rattles and it's driving me CRAZY!! Bringing to the dealer shortly, will have this thread for when they tell me they've never had this problem

I have the same issue. exactly like the way OP explained....

Just Fixed mine. Finally some peace. I hated that sound.

Awesome, thanks for posting this!

The video that DEAD CIVIC put up is, for me, the definitive guide to a DIY solution. One does not need to take out the entire headliner! I only took out the rubber door seals, upper B-pillar covers, and the rear hand grabs. Then I gently pried down a section of the headliner enough to tighten the six T30 screws (one of which was barely finger tight). Voila! No more popping sounds!

It's a tight space for sure, and a low-profile T30 wrench is required, but it is entirely doable for anyone who is passably handy, like change-your-own-oil-and-filter handy.

what do you mean?

Wow, I just came across this thread and thankfully (but unfortunately) you guys are experiencing the same things as me. I have 2014 E350 w/ pano roof. I thought I was going crazy! I just got my (brand new to me) car delivered this week and have been hearing these freakin' creaking sounds from the back every time I would go over a bump or something; driving me insane--imagine the discontent over hearing this in my "new" car. At first I thought it was the rear headrests and then the rear parcel shelf, but now it helps to narrow it down exactly. You should have seen me, I was in the backseat like a wild man pushing and tapping and squeezing and testing every panel I could get my hands on, hoping to isolate it.

I will be taking her in to get this covered under warranty; anyone know the exact TSB on this?

I waited until it got really bad. dealer fixed it right away. it was so bad that you couldn't make any elevated turns (turning into a driveway up the slope...). Dealer knew what to do right away. They said loose bolt.... the question is when will it return and how much will they charge me when i'm out of warranty.............

Just make sure they use loctite on the bolts. Shouldn't loosen again.

Yes that's my fear too.

To all those who fear the high cost, I want to say that if you're even remotely handy and have the correct tools (that aren't specialized nor expensive), you can complete this repair in an hour or less. It's really not a difficult task.

Of course, if you can get the dealer to do it for free, well, what's not to like?

Would you explain a little bit how to do this job as you say it is an hour or less job?

Just watch the video mentioned in post #41 above. Seems to be about 6 screws and you don't have to take the headliner all the way down.
