First I have been to the dealer once regarding this and need to go back because its still a problem. But every bump in the road or angle or even taking a fun corner the moon roof rattles really bad.

The dealership said it was the wind visor and they said they adjusted it, not sure how. Well it was good for the 90% the way home and then it started acting up again. The car has 4k miles.
After I came home that day I looked at the visor myself and added some tape to the plastic things that rest on the wind visor and slide up as you open/close the thing. This got rid of some of the noise, I tried some thicker felt padded furniture stick on things that I cut in half so they werent so thick. It helps alot, but doesnt solve the issue. It seems like the rattle from the front of the roof goes away with these pads, but noise from the middle or driver rear still is there. It sounds like its coming from two places in the roof.

Before I go back to the dealership, has anyone had similar issues and had any fix your dealer did?

 

Mine is at the dealer now for similar noises, last I heard they removed the headliner and were still diagnosing. I'll let you know what I hear. Just FYI - I went for a drive with the shop Forman when I dropped it off, he heard the noises, it seemed to have helped mitigate the back and forth and "we can't hear anything" routine.

 

Spoke to the service writer today, they tried adjusting and placing some felt in some areas but that didn’t work. They ordered a new frame assembly, should arrive tomorrow. I’ll let you know how that goes.

 

Mine RDX '19 is in service dept. now for this same knocking noise you describe. Also, headliner makes rattle/vibration noise over rough roads. I had to drive around with the tech for about 20 minutes before I could duplicate headliner vibration noise. Lucky for me he was cool young guy who liked to talk. I was so relieved when I finally re-created noise. It wouldn't make the noise till after 15 minutes of driving. Then it go worse and worse...thankfully. I could not repicate the frake/moonroof knocking noise on sharp turns. But he seemed cool enough to look into it on the "down low", while it's in service...I hope. I look forward to how it works out for you XMERC.

 

I got mine back after about two weeks, they ended up dropping the headliner to pinpoint the noise and after much diagnosis they ended up replacing the entire sunroof. All noises have been eliminated. I did have to go back after the first repair as I noticed one of the rubber trim pieces was hanging off causing wind noise, they repaired that too. All is good, happy now.

 

This roof that Acura has designed is complete garbage . My dealer replaced my compete roof 3 times . First for it stuck in the open position and it won’t close . Second for it constant loosing calibration and making noise . Third for making noise and stuck in the vent position . After that it was good for about 1 month and it’s back to the dealer for same problem. Loosing calibration and noise .

 

My new 2019 RDX moonroof creaked when the car would flex (like when turning into a plaza). They had to replace the moonroof frame. Big job. It worked though. No more creaking. Then I sold it and bought the 2020 RDX. It makes a wind-whistling noise. I can't win.

 

Just bumping this up to see if anyone else has experienced rattle noises from moonroof when going over bumps/around turns, and more importantly, how was the dealer was able to fix it (if it was indeed fixed).

Thanks!

 

Yes I have the same problem! Just realized today that when I close the sunroof cover it stops. I hope when I bring it into the dealership they can replicate it.

 

Same. Mine's coming from the center "beam" that runs across the pano sunroof and separates the fixed glass from the retractable sunroof portion. When I bump it with my fist, it will replicate the noise. The build quality of these RDX's is subpar IMO. I've had to fix two rattles myself in the A-pillar and the rear cargo floor and I still have a clicking steering wheel and creaky driver's seat (I know the fix for this, just too lazy to fix it).

 

Yesterday I opened the sunroof a bit, then sprayed WD-40 on a cloth and applied it to all of the rubber gaskets and the piece that connects the fixed from the sliding part of the sunroof. Took the car out today and it seemed as if the rattle was gone! I’ll let you know how long it lasts.

 

Did WD-40 do the trick?

I have the exact same issue. With the cover closed there's not rattle. I banged on the headliner under the cover and it mostly seems to do the trick; rattling went down significantly.

 

It's the wind screen. You can remove it very easily. I narrowed it down to that and removed it and the rattle is gone. With the sunroof cover retracted, you can actually shove your hand past the seal and feel the wind screen rattling around as you drive, knocking against the metal frame of the sunroof.

 

Yes, it seems so, but I tried to secure the headliner by pushing on it as well and I also and fiddled with the windscreen...

 

I’ll take a look and see if mine does that

 

It will. It’s a design flaw more than anything. There isn’t enough spring pressure to hold the windscreen down while the sunroof is closed. That or they could have used materials that weren’t hard plastic on metal, which would deaden the noise. I suppose you could try lining the contact points with felt, rubber, etc .... but it wouldn’t be a sure thing, no idea how long it would last and removing it is so easy I just went that route. Plus, I can count on one hand how many times I’ve opened the damn thing, and three times were while trying to figure out the rattle and for removing the windscreen.

 

the thing is it makes a big difference in sound and bug getting in the car when you don’t have it, im not removing mine

 

I don't have a moon roof rattle.

 

I brought mine in earlier this year (after about 6 months of owning the 2020 RDX) for the strange rattle from the roof. Acura Service knew exactly what it was and so they greased the acoustic seal and primary seal of the roof.

Haven't heard anything since. Although now steering wheel is making creaking noises (cheap plastic?).

 

That seems like an easy fix. On mine i noticed if I just open/close the the moonroof it stops.. I'll try the greasing solution.

I think I also have the same one, either coming from drivers door or somewhere on left side of steering wheel. Haven't been able to pin point it.

I really love the car, but the rattles, oh so many rattles....

 

Greasing won’t do anything. It’s the plastic windscreen frame hitting against the metal frame of the sunroof. Every 3G RDX will be effected on rough pavement. It’s a design flaw.

The build quality of the RDX is very poor. And in being nice compared to what I usually say about it.

 

Do of any of you get a popping noise when body flexes? I get that every time when the car is at an angle. Sounds like it is coming from the cross beam. I've put some foam tape around the area. Still makes it. Dealer of course has never heard of this issue.

 

the build quality is not poor overall, some vehicles have a few issues but this car is selling very good and the forums only represent a very small percentage of the people that own them, probably less then 2%. I find mine overall is a very solid car. This could be easily fixed with some foam pad with tape backing placed where it contacts the other piece of metal, I will try it and see if it makes a difference

 

FYI, I have NO rattle from sunroof. I've investigated the plastic windscreen frame and it seems to work as designed. No rattle designed in, in my RDX anyway. AND we have plenty of rough pavement here.

 

I just spent 10-15 minutes in my garage trying to figure out what leomio85 is talking about. I opened the sunshade, pushed my hand through/beyond the rubber gasket (which is very tight itself, and would seem to block a significant amount of noise coming from beyond it) The plastic windscreen frame is as tight against the top as seems possible. I tried pushing it down to see how much "give" there is in the spring when it is compressed...virtually none. I really don't see how it could rattle here. But, what do I know?

Prior to doing this, as a specific test for this, I drove on several rough bumpy roads (of varying roughness), with the sunshade open, pushing my hand through the rubber gasket....felt no looseness or change in (no) rattle. I drove with shade open, closed, sunroof open, closed, etc, and I hear no rattle from here.

Call me stupid for actually looking for rattles that don't exist, but I was a out for a ride on nice balmy morning, 88 degrees at 7:00 AM, now, (as I write this at 9:20 AM, it is 98) Thought I would again investigate what leomio85 keeps mentioning.

I hope that there are others, like myself, who also don't have this sunroof rattle.

 

Maybe they changed the spring pressure due to other issues with the moonroof? Maybe a bad batch of “springs” from the manufacturer? I don’t know what the cause of it was, nor can I explain why yours seems fine. The issue arose before 8k miles and less than a year on the car. Rough roads (ie: typical pothole filled roads in NY) would make the windscreen go nuts. I also never use the damn thing. I literally used it once before having the issue. All I know for sure is that it was the windscreen on my vehicle that was the problem, and I certainly can’t see myself being the only one.

 

100 % have the same issue. Moonroof closed, it rattled; i opened it just a tad, and it stopped. Haven't had it in a while now, so I'm not sure what to think anymore...hope it stays that way.

 

OP, I had similar issues with my 2019 RDX A-Spec SH-AWD. The wind deflector was causing chatter, so I've placed an inch of black duck tape on each end (about a few inches) where it bends on top while the panoramic moonroof was retracted. The one that the dealership resolved was a metal to glass sounding rattle from the rear of the vehicle (was audible when you tap on the panoramic moonroof). According to their resolution, it was a module above the cargo area had to be "taped-up".

The problem is about 80% gone.

I suspect that the design of where the rear liner attaches to the roof beams are held by a combination of velcros, and magnets too. Now and then, I hear a chatter behind me (above where the rear passenger sits). If I have the passenger push-up on the headliner, it goes away.

My wife just picked up a 2019 CPO RDX Advance with the usual dashboard rattle and sunroof noise.
Went back to the dealer and one day later dashboard rattle is fixed, loose clip they said, and they also ordered a sunroof seal and some other part to fix that noise.
Unfortunately, the seal and that other sunroof part is on national back order so this repair will take longer.
So, go back to your dealer. They will fix it.

 

Were you just getting rattling noises or popping / snapping noises

 

Both, rattle from dashboard and loud crack from sunroof.
I was told they removed gauge cluster to fix dashboard rattle.

 

That 100% sounds like the wind deflector whacking against the frame of the sunroof. I had the same issue, removed the wind deflector entirely and the problem is resolved. You could probably add some sort of foam/felt insulation to stop this issue, but I don't know ... easier just to remove it since I never use it.

Do yourself a favor and take it to a road where you know it makes noise on. While opening the cloth cover put keeping the sunroof close, shove your hand past the rubber seal and feel around for the wind deflector. You'll be able to move it around as there isn't much spring pressure. You can emulate the noise and verify if that's the sound your hearing. To confirm 100%, drive the road and feel how much that wind deflector moves while on rough pavement. I did this exact process to confirm that it was the wind deflector that was causing the noise. Initially I thought it was the cross beam of where the fixed glass meets the movable glass.

 

Did they put it back?

 

Dashboard is fixed 100%.
Yesterday I was on unpaved road with a washboard like surface and no rattles of any kind.
Dealer ordered replacement parts for sunroof so I'll report after they call me back to install it all.

Leomio85, I'm a hands on guy but only when all other options are off the table. I'll let my dealer fix it and earn few nice bucks from Acura in the process.

 

[mine goes in tomorrow for the new sunroof frame Werks that they are going to make it worse
