It only occurs during start up after it has sat for several hours. I notice it most in the morning. Noise is hard to describe but almost a bubbling sound. It goes away fairly quickly once the fan kicks in then I don't ever hear it again until it's been sitting for a few hours.

I'm a recent new owner of 2008 and I hear a sound after idling for about 10 seconds on a cold start that's different. It lasts for about 4 or 5 seconds. I thought it might be the ABS system cycling. So I'm interested in your noise whether it's normal or something abnomal.

I bought it used with around 20,000 miles on it and have only had it for 2 months now. It is still under factory warranty so it's covered but I'm just curious as to why something like that would happen when it only has 25,000 miles on it. I get nervous about things like this after reading so many of these blogs. The dealer is keeping it over night to hear it on a cold start in the morning they are thinking at this point that it is the air pump injection but want to make sure. Is the noise you hear right before the fan kicks in? Mine is. I will let you know what they tell me tomorrow.

"Is the noise you hear right before the fan kicks in? Mine is."
 
What fan are you referring to? The blower fan for the interior vents? The radiator fan that comes on at high engine temps? The same radiator fan that comes on when the HVAC is in A/C or Defrost mode?

Yes, it's right before the fan kicks in. I don't know exactly what the fan is but it is. I wouldn't think it would be teh high engine temp fan since I normally hear it when I start it up cold, so it could be the radiator fan. The fan sounds normal to me it's just the noise I'm hearing right before that is abnormal. What year is your car?

Since a diagnosis based on your symptoms is impossible without actually hearing the origin and type of noise, my advice is take it to someone you can trust.

Is it the same by laserblue

My new neighbor just moved in an he owns a 08 Pontiac Vibe still on warranty.
 He was asking me if he can go to our local G.M. dealer for some repairs on his car? The problem is, we don't have a Pontiac dealer in our town only a Chevrolet dealer. I told him that any G.M. dealer will repair his Vibe even if it's a Chevrolet dealer.
  But just to make sure because there's nothing that Chevrolet sales that resembles a Pontiac Vibe..
  What do you think?

Wrong forum however,
 
Any GM dealer "might" repair it for him. However, since Pontiac is still a franchise getting warranty payment is unlikely. Best ask before inserting foot.

No more Cobalts by laserblue

If I have this right, the're won't be a 2010 Cobalt next year?
  I heard it will be replaced by the "Chevrolet Cruze"?
  When will the production and sales of the "Cruze" begin?
  What will be the MSRP?
  They said that the Cobalt replaced the Cavalier would be superior to it and now I heard that the Cruze will replace the Cobalt and be superior to it to.
  Looks like the Cruze will be something to look at in 2010.
  Will the "Cruze" be out in the same time for the U.S. and Canada?

Yup, they changed the car's name to Cruze. How messed up is that? A horrible name and all it really will be is a better Cobalt, with a wider track, a better interior and a Korean designed exterior and interior.
Cost is not known at this time and availability will be determined later.
I am not a happy camper.
