I have noticed this when my 2015 GX is in relative quiet environment. If I close up the front passenger side window, I always hear some weird humming sound during that somewhat slow-motion movement at the end of the closing (vs my front driver side window). I have attached the recording, it is 8 seconds long, the humming noise is from 5 seconds mark. On highway driving, I never notice this due to wind noise.

My GX is a few days away from CPO warranty expiration date, so I want to check with community here, maybe I am have too good an ear and this shall not be a concern at all, or the front passenger side window motor is bailing out soon, or this is just a GX slow window closing feature. I have no issues with any windows at all.

Thank you.

video of whats happening - this happens once a month

now based on the googling ive done, im assuming its the regulator/motor going out. but before i place the order, is there anything i can try?

this window also goes up the slowest/last to close.

Looks like anti-jam is kicking in.

Oh man I have the same issue. Rear passenger side window.

I think the window is binding. You could try cleaning and greasing the side channels with Dielectric silicone grease and see if it helps.

Mine is pulling out of the assembly that holds the window (with the slider that the regulator uses to "push" the window up and down). When it tries to go down the window binds and it pulls out of the rubber piece.

I have a new rubber piece on order (the window slides into the rubber piece, which slides into the metal assembly). I am going to RTV it in place and see if I can figure out why it is binding, probably next Weekend
