i think it might be the breather tube will check with the dealer on my next days off other wise the car is perfect

I have a '07 and I have the same problem with it shutting off with little amount of gasoline put into the tank.  It must have to do with the angle of the nozzle and the angle of the tank opening.  I just take it off "auto" and just hold the nozzle while it's going into the tank at a much slower rate ... takes longer but it doesn't shut off.

Never had the problem on my 02, 07 or 2010.  May be that you need to back the nozzle out about an inch or so and then try it.  Have had that problem with some pumps on my 08 Impala, and that seemed to take care of it. Think it may have to do with how the nozzle is made and how far it goes down into the filler tube (they are not all the same).

I agree.  It's usually because of the specific nozzle being utilized.  Try pulling the nozzle out of the tank a tad (1/4 inch or so).  This will impact the pressure of the fuel in the filler tube, which (I believe) is how the nozzle determines when to shut off ... THINKING the tank is full.  This *premature* shut off happens on many of my vehicles (Corvette and non Corvette) from time to time, at various fuel pumps.

If it were me, I would NOT take the car to a dealership for analysis ... unless it is under warranty.  Then again, remember, some dealerships will charge a diagnosis fee if there is no result, or if there is no defect found with the vehicle.  I'd hate to be told there is no problem, then get whacked for 1 hour of diagnostic$.  Try asking the service advisor if he has had similar problems ... or if it *might* just be the angle of the fuel nozzle.

I have had the same problem with my 07 Z51. I took it to the dealership when still under warranty and they supposedly could not find the "problem". I learned to live with it and it takes me a long time to fill up.

Yes, I've had the same problem with my 07.

I too have an 07 C6 and had the same problem. I took it to the dealership and, of course, they found nothing wrong!

I have a 07 and have no problems with mine. Every now and then I get a gas pump handle that is touchy and have to adjust the fuel nozzle a little bit.

I tried the upside down nozzle bit and it works. Weird!

It does the same thing as pulling the nozzle out a little ways (1/2 to 1 inch should do the trick).  Try that if you don't like turning it upside down.

My 05 is picky also,, the upside down thing works.. Next time I am going to try pulling it out a bit. Not all the time, different gas stations different problems. Some times I get a full tank and then some. Mostly almost full not all the way. Last year when we went to Hampton Virginia for the convention, it was about ever other tank full. I just have to deal with it..
