Nope, they do not have a TSB for that one.

 

Reading this thread, I was all excited that the answers to my problems was about to come. But I have a 2012, and people here seem to think the 2012 is fine and dandy, silky smooth compared to the 10/11. Makes me wonder just how bad the 10/11 is that I could feel the 12 is horrible.

For giggles, I'm taking my '12 g37x in, see if they can do anything.

 

I just noticed that my mpg display is now from a scale of 0 to 60 mpg. Prior to the ITB12-027 update it was 0 to 30. I haven't put enough miles on it to know if mpg is really improved, but it seems like it tend to reach between 40 and 60 on the scale when I'm coasting.

 

I have a 2007 g35x with 50k miles. When I accelerate from a complete stop my car vibrates at low speeds. Then it would've smooth once in 3rd gear. It's on and off, sometimes it would vibrate and sometimes it won't. I'm not really sure where this probem is coming from but it feels like it coming from the transmission. My steering wheel also vibrates. I was wondering if it is my transmission would the reflash resolve my problem? Any help would be appreciated. Btw there are so many pages so I couldn't read through the whole thread, if anyone had a solution to this.

 

@HappyG: FWIW, my 2011 has always displayed 0-60 MPG before and after the ITB12-027.

@vzeng: This will not apply to a G35. Use the TSB site linked earlier in this thread to find if there is a TSB for your model.

@killingme: An early 2012 may not have the latest software so there could be an update for yours later. And yes the 10/11 was pretty bad, depending on who you ask.

 

"7 speed working as expected" bah.

 

I'm pretty sure my 2010 showed 0-60 before the update...

 

Hmmm...the last time I paid attention to that it was 0 to 30 mpg. Weird. My G was manufactured in 02/2010.

 

OT: Is anyone else slightly bothered by the two different diameter blue rings on the gauges? I know they did it to fit more warning lights, but....

 

Not a bit.

 

Nope, but I am bothered by my paint chipping off just by looking at it and my 09 transmission that's "waiting " to be "hopefully eligible" to be reflashed

 

So is this guy full of crap? It's been 3 days and nobody can confirm this?

 

He probably just got the 175 TSB since his never was reflashed. I don't think the dealer can even apply the TSB unless your VIN falls in range, I think the computer only allows that range to get the fix, and since no 09s are in that range it wouldn't be possible to have it done.

 

I just got my 2011 G37-S Sedan reprogrammed/reflashed today (Socal area, Glendale Infiniti)... They did it in about 45 minutes (not bad at all) and it does feel way smoother and responsive. I also cleaned out the throttle bodies this past weekend so it feels like I'm driving a whole new car.

I also notice this popup after the TSB update when I start my car. What is it
