It really isn't that big of a deal, but I was wondering if anyone else's G does this.... When it is cold out, after my G has warmed up and I have the heat running, when I come to stop light or even a drive thru, if I am stopped for more than a min or so my heat turns to cool air. My wifes QX56 does the same thing but hers would have to sit for like 10 to 15 minutes.

 

I had the same problem. You have to bleed the radiator, it has air in the system. Once I got that done, I was nice and toasty at stops. Oh yeah search you fvck lol jk.

Mine does this too, but I am far too lazy to fix it...

 

Yep there is air in the system. I had the same problem and it's not hard to fix.

 

mine has an issue along the same lines. I noticed that the heat works much better when moving. When im stopped it still comes out warm it just doesnt come out as fast and i can barely feel it.
