|  G8 Problems
Anyone had problems with their 08 GT having a whining sound at or around 60 MPH? Took it to the dealer they said this has been a common problem? So they replaced the Dif. But no fix yet?? Gm told the dealership It my be the tranny anyone heard about this?? Thanks

Check around on the other G8 forums. It seems to be a common sound that comes from the tranny. | |

It's the 6th gear sychro's (?). Very common problem. Turn up the radio, it will be fine.

Only problem I've had is a noisy sunroof with the visor open. Dealer said my was quiet compared to the other one they had on the lot.

Anybody had any problems with the car stumbling when coming to a stop. Basically stock car. Just intake and mufflers. When i am coming to a stop the car bogs down a little then picks back up. reminds me of my cammed camaro before i got it tuned better. I have hptuners and have been trying to get rid of the problem but can't seem to figure it out. I am not sure that i have all the perameters on the software. It doesn't have a lot of parameters for idle tuning and am not sure on all the new tables and what they do as well. Getting frustrated with this. A new car with no major mods should not do this. Any ideas?

I haven't had that problem, but my headlights have condensation in them. Anyone else have that problem?
