mine started to happen few weeks ago.

 

Try Tightening The Seat To Floor Bolts It Worked For Me!

 

Really? Hmm, I'll take a look if it happens again after it's in for service.

 

i just got a call from the dealership.. reagarding my squeaky seat.. they said are just going to give me a brand new seat! i gotta wait 30 days though.

 

Nice work!! Were your squeaks isolated to any specific area?

 

i woudl think it was either the rails.. or the joints where it reclines. well whenever i got in and out of the car it would squeak.. or whenever go on long turns.. however, when i went they said, "I like how you dropped your car.. " he was obviously implying my mods but he said, "well I'm not going to get into that because others will/or say your suspension caused the squeaks"

 

Funny, all he had to do was a little research to see it was simply the faulty clips that were likely causing the trouble. Still, I'm glad you got a new seat out of it!

 

yea i'm glad.. i can get a seat w/ no wrinkles (at least for a few weeks) and a semi new car smell hahah

 

Your car looks good btw! Any links to more pics?

 

My seat has developed a squeaking sound from the left bolster around the side of my back. It's weird, it comes/goes mostly over bumps or if you move side to side on the seat. I'm 185lbs, no weigth jokes.
Any one out there has this issue on thier IS250/350?

 

There is a TSB on this...

PS - Lose some weight...

 

the dealer just fix mine. the guy said there is TSB for the seat. Anyway, they fixed it that's all it matters..

 

Awesome, thanks a bunch.
haha on the weight thingy, I'm trying

 

Just had to go back for another fix on this, about a year after my first one. I'm wondering if this will be a repeated problem. Sounds a bit like a flaw. Thoughts?

Here's the TSIB:

I've found this to be the common cause of this problem as well.

I wish guys would stop presenting TSIB unless they knew it would indeed rectify the problem. The seat base squeak is a very generalized TSIB that applies to lots of models concerning removal of locator pins that are noisey against the body of the car. There aren't any locators on the IS so that TSIB doesn't apply.

I've generally taken loose the seat and applied silicone paste to the body where the seat mounts to and reinstalled the seat. That has taken care of all the IS seat squeaks I've encountered.
