My dealership just performed ITB09-037 for my prematurely warped rotors.
My 2008 G37S Coupe recently started giving me pretty nasty steering wheel vibration under braking from higher speeds (50+ MPH). As we all know this is usually from warped rotors that need turning/re-machining but at 12.5K miles, I knew that this was way too premature for my vehicle. Especially considering how gently I typically drive.
So I took the car in and turns out that, yes it was prematurely warped rotors. So they re-machined them for me - and fortunately they found that a brand new, fresh out of the ever baking-Infiniti oven TSB applied to my car.
My work order says it's ITB09-037. So they machined the rotors as per ITB PX43AA 2.3 & they overnighted 2 backing plates that serve as heat shields to go with the rotors on my front wheels to keep them from overheating so as to prevent future premature wear. The car brakes like a charm now and apparently these are the 2 part numbers for both front rotors as per my work order:
PLATE-BAFFLE-41151-JL30A and
PLATE-BAFFLE-41161-JL30A.
Another nice thing is that now not only is the braking smooth (no vibrating wheel) but my squeal in reverse is GONE.
Turned my car in Wednesday at noon, got a loaner, and got the car back next day evening. G37x sedan is fun but I always miss my baby when she's in the shop.
Depressing...
This is like the 7th warranty/TSB type issue I have fixed on my G. It's pissing me off because I keep praying each issue is the last for a while but I keep having to go back. If my G continues this way my life will really suck after warranty is up. On the brightside I now have a work order number for a free warranty service that I can still use to apply for a gift from infinitiserviceevent.com. If there's a such thing as karma then I'll win something cool.

I've had braking vibrations since 12K miles and the dealer said they would turn the rotors at a future date (24K rings a bell). My vibrations are tolerable but anoying. I'm at 19K now but a TSB would be a much better solution. Thanks for the info.

Re-surfacing warped rotors will only make them even more fragile to warping.
And heatsheilds only protect the hoses,seals boots etc by typically containg the heat (unless they have vents built-in or something). This could cause further heat problems and rotor warping ?
I'm confused over this...

Yeah, the work order says they were baffles that were installed so maybe like JLai said they may direct air to the rotors? I don't know! One thing's for sure, they better not warp again anytime soon - or they're gonna hear it from me.

I don't post much on here, but I'm a pretty active member over at g35nyc.com.
I've been having the same problem, only mine steering wheel started to vibrate at about 8,000 miles. Since then, the dealership has resurfaced my rotors twice, but to no avail. Actually, it's worse now (I'm at about 13,000 miles now), as there is an added grinding feeling when I hit the brakes. The dealership says my pads and rotors look fine though (don't ask me how that makes sense when they admit they feel the problem when they drive my car), and told me that if I continued to have this problem, they would swap my rotors and pads out (this was before the TSB came out). That all changed when they decided to blame the problem on my painted calipers. They will not install these heat shields or what ever they are because of my painted calipers.
