Got my car back from dealership 5 days ago, so far so good, they replaced the transmission and the raditor. Have only put on 60 miles since I got the car back, today while stuck in traffic due to an accident I noticed smoke or steam coming from font of the hood, hopefully that is only because of the new radiotor, the temp did not rise any so hopefully thats it. Another car towed in G6 towed in after mine had the same prob, they replaced the trans and the new trans was bad. I know these trans they put in are rebuilt but isn't there any quality assurance done by GM on this? I am beginning to hate this G6 HTC that looked so dam great when I got it!!! Good luck, at least yours is a lease, I am stuck!!
