First time posting.
Vehicle is 2015 NX200 Non Fsport, as the title states, driver side seat squeaks when I get in and out of the car. I know its not the suspension or the seat rails since the noise is heard when pressure is applied with hand, and it defenitely sounds like some spring is loose (like old mattress).
Been to the dealer twice, 1st time they moved around the foams. 2nd time they lubricated the springs come in contact with the foam. Still no luck w/ a permanent fix. The dealer says they'll check w/ mainland and get back to me for an update.

Anyone else hear this noise?

thanks in advance

 

Welcome to the forum. I recall my F Sport seats squeaked sometimes but not always. It was temperature dependent. It never bugged me enough to troubleshoot it, but it seems like the squeak was coming from the side bolsters rubbing against the side lower plastic seat housing. As a test I'd try stuffing a thin cloth in between the sides as far down as possible just as a temporary test to see if it stops... Good luck

 

Thanks for the reply.
Unfortunately, it seems like thats not the case for me. That was my first thought as well so I tested to see where the noise was coming from, and it's definitely from somewhere deep under the lower cushion. It's actually been getting worse, over every bumps and uneven surface the squaking noise is heard. I can easily reproduce the noise by pushing down on the center area.

 

Not an elegant solution, but I had a spring noise on a new MB 320, and found I could quell it for several months by spraying some silicone under the seat area. I never found the source but the silicone did.

Thanks for the reply.
I have ventilated seats and there's a unit sitting right beneath my butt, where the squeak originates. Not sure if spraying the silicone there is the best idea.

UPDATES:
Took the vehicle in for inspection 4 times within the last 3 months, all failing to fix the issue. We know where the sound is coming from, but just cannot find a way to fix it. Lexus of Honolulu has been very generous and showed effort in fixing this matter.

They will be replacing the entire unit that is surrounding the noise.
