I have been noticing a slight vibration in the front of my 2006 Cobalt SS/SC. It only happens in the mrining when it is very cold. It almost sounds like a bearing or something. The car also pulls to the left. It could use a front end alingment. After a few miles when the car gets warmer the vibrations goes away. It is not my brakes because nothing changes when I brake hard or light. Took it to the dealer last night so they could test it in the morning. What do you know, everything checks out fine. Everytime something goes wrong they tell me its normal and everything checked out fine. I'm starting to get annoyed. I would like this fixed before I order a stage II and GMPP exhaust.

 

You have a troll living in your car then LoL

 

I have the exact same problem, I wonder what the hell it is. Keep me posted!

 

these tires are really really hard when it gets cold. that's road noise and vibes from the tires.

I've had a whole bunch of tires guys tell me that anyway while I was searching for tires.

 

Same here , i think the tires have alittle flat spot in them from sitting all night that makes noise when taking off on a cold morning . I could be wrong but thats what mine acts like .
