They replaced my rotors under warranty for this exact thing. There is a TSB for it somwhere....

Then how come after they resurfaced mine under the TSB the vibrations I was getting in the steering wheel went away? It was definatly more prominent under braking but there was still a very slight shudder above 60mph even when just cruising.

Yes there is a TSB out for this. Apparently there is insufficient air flow around the front brakes that has been causing them to warp prematurely. For the TSB they resurface the rotors and install shields like on the rear brakes to help direct air flow better. I think the TSB states it will only cover up to 15K miles or so, but I've heard people getting it done with up to 25-30K miles.

Update: Went to infiniti of Manhattan and had my rotors/pads replaced under warranty. TSB 09-037 is what refers to prematurely warped rotors.

BTW, i have 10K miles on my car

I think I had around 30k when they replaced mine...

Presto

anyone know where i can get a pdf of this tsb?
would like to show it to my dealer as this problem is slowly cropping up on my g.

Well I took my G37 coupe in and the service writer said there IS a TSB for the front brakes. Apparntely, there back plate is too small causing the rotors to not wear properly and causing juddering. He said they have recieved the new backplate and will resurface the rotors. I am picking up my coupe this evening. I did a google search on TSBs for this particular problem on the 2009 G37 coupe and found this:

FYI the TSBs are available online as a public document by going to the NHTSA website's technical bulletin section: ODI - Office of Defects Investigation. Here you can do a search for any vehicle in their database. I did one for mine (2009 G37 coupe) and found this:

As everyone says, it's about the rotors. Also it's not just you, but for every G. Somehow infiniti rotors gets warped very easily.....

Stoptech Rotors FTW

demuslee

Just got my car back from the dealership ... they replaced the backing panel or whatever part that was causing the rotor to not cool properly and resurfaced the rotor - no charge. The brakes feel 100% better now after the fix. Hopefully they last.

I wonder if this affets the verts, since parts are shared up to the a-pillar.

If it's vibrate and pulsing when you break at higher speeds. I'm gonna say it's your rotors. Need new one or you need them machined. Don't brake so hard to avoid that problem in the future. Doubt Infiniti will cover your breaks and you probably need new pads also once you machine or change your rotors.

joey_v

I went to the dealer when I was 11K... they said they had an ongoing issue with the brakes and PREMATURE warping - I got a full free brakes set for all warped rotors.

MAKE SURE YOU GET FREE ROTORS! DO NOT pay for it!!

This is Infiniti's problem, they should not warp so early.

Mike S.

My brakes are starting to warp a bit too

I'm at 15K.

What is intersting is that my Altima SE-R, which came from the factory with the larger brakes from the Maxima (big deal right)..started to warp too. BUT...they seemed to fix themselves...weird.
