After reading more carefully the TSB I don't think it will help with the noise...
It is getting louder in my case even in good roads if I get a small depression or hole

Looking forward for feedback from the ones that already reported it.

I've reported it already. The mechanic showed some effort to help by applying some adhesive foam on the inside of the trim, but it didn't work.
I'm tired of being mechanic-dependent so I've decided to take matters into my own hands.


He disassembles it so easily
Today I've successfully disassembled the door trim, It's quite easy If done carefully, however I felt like I had to apply a lot more force than the guy in the video to release the clips.

BTW The door on the video is from the passengers side, but the only difference is the window control panel, which takes a bit more effort to pull out.

I haven't noticed any loose elements, the squeaky noise was absent today when I was driving without the door trim. I have a feeling that readjusting the bottom window seal (the last element removed in the video) might have fixed the issue. Nevertheless tomorrow I'll still do some test drives without the door trim.

Today the squeaky noise returned when I was pressing on the window or the metal frame by the window with my finger when door was closed. The trim and the seal were removed. So the search continues.

Can you guys check if the squeaky sound is present when you press your finger against the window when the door is open?

I might have found the source of the squeaky noise, it looks like its the two contiguous seals between the front and rear doors that rub against each other making the sound probably due to low air humidity. I heard the squeaky noise today so I stopped the car and started pressing against the B pillar from the outside right next to the seals (marked by a red line in the picture below) and I heard a similar squeak.

I find it odd because the noise seems to be a hard knock in my case. A loose bolt as someone referred.
In any case I'll close the door with some foam in the middle and drive around. Or are the seals easy to temporary remove?

I have the same issue. When I drive the car to work in the morning when it is cold the window makes a slight rattling noise particularly over coarse road coverings but is fine when going over smooth hot mix. As an experiment I cut a strip of stick on foam around 1cm wide and long enough to fit in the u channel at the top of the window frame pretty much running the full length of the top of the window. I then closed the window which crushes the foam against the top of the u channel. To date that seems to have addressed the rattle and I haven't heard it back. I had a look at the areas that arek_4k identified and there are rubber pads inside the top of the door frames in the areas indicated that have pads to stop the top of the door frame rubbing against the inside door frame. If the rattle comes back I was going to try stick on felt in these locations to provide a little more separation.

I would recommend trying the foam solution in the first instance as once it is crushed up in the u channel you can't see it when you open and close the window. I used closed cell 3mm foam and also have some stick on 6mm foam I can use as a backup if the 3mm compresses too much and stops holding the top of the window properly.

I've had the same rattle I thought it was the glass when pressing on glass it went away turns out its the rubber seal at the top of the door which can only be seen with the door open I put a bit of foam under it and silent since

I'm sorry to say that putting the foam there (under teh red circle) didn't help on my case. Weather is getting colder and the noise louder.

I think on my case it is coming from the glass rubber trails. Pointed in yellow.
They are wider than the glass letting it loose. If I press there, noise is gone. Now just need to figure out a way of fixing it...

Also getting rattling around the B pillar around the seat belt assembly
Me too, and i only heard it after it got cold. Does anybody know of a TSB on fixing this? My assumption is that it's not covered under warranty after the first year. Has anyone been able to get the dealer/Mazda to fix this under the three year warranty?

cllpm4u read the latest posts... are you sure is from the B pillar?
Press the rubber trails against the glass and let me know if it stops...
I get rattles when it's cold from the window and the seal but only when the window is down. When it's up the rattle goes away.

Hello all

Same problem here, that's how I found you guys.
First I thought the ratlle also to be from the b-pillar. But removing the interior cladding proved to be a bit difficult. I was afraid for applying too much force and breaking something.
After a couple of weeks with the weather going colder and dryer, I was driving around with the rattle as usual and started pressing gainst the window. All of a sudden, the rattle was gone.
Now I have been researching this site, and found arek_4k's post. I investigated and it seems like a good possibility for me. Today I went and taped the area with some painters tape to see if the noise would stop. When standing outside and pressing on top corner of the door, the noise didn't stop, but while driving the car, I couldn't hear anything.
But I must confess, while investigating the area I was pushing the rubber seal quite a lot (the one in the picture above within the red circle) making the seal less 'stiff' and warmer than usual.
So when I removed the tape, there was also no noise to be heard while driving.
I then went and washed the car, and the noise you hear when pusing on the door standing on the outside was also not there.
So I now have some painters tape in my glove box and a kitchen sponge which I could insert into that cavity of the seal. But my best guess to definitly locate where the noise is coming from, is to ride around as usual and upon hearing the noise, make the rubber on the top corner wet and warm and see if the rattle is still there. I assume that the cold and the resulting stiffness of the rubber is causing this problem. Not sure if unserting a sponge is going to solve it, but I first want to make sure this is the cause.
The material from which this part is made is different than the other seal araundthe window and door. Even when it is cold, the other seals are still very flexible and soft.
I'll let you know when I find something.

I drove around pressing on the inside of the corner of the window and the rattle disappears, so it is the window, not the B-pillar. Keep us posted on a solution wheelis. What I do know is that I can't drive around with my hand pressing on the window all winter.

This is what the 2021 looks like:

279989


279990


A few of possible clues:

1) That arrow should be lined up with that part of the door frame.

2) It looks like the space between the corner piece and frame of the door is intentional.

3) There appears to be a twist in that corner piece where in meets the curved weather stripping in @Gazfay's picture above that's no longer present on the 2021s. Might be a clue as to what the engineers were trying to change/fix.

4) Can you see the part in the frame where there used to be a hole for a clip? Possibly another clue.
