Does anyone have a whirring kind of electronic sounding noise when they first start the car and drive? Hubby thinks it sounds like power steering pumps when they go bad, if that helps. Anyways, the car does it until it's been driven a few miles or gets warmed up, then it goes away. I didn't notice it until a week ago, probably because I was using auto start every time I drove it when it was cold, so it was already warmed up when I got in. Not sure if it's a problem, just wondered if it's a common sound.

 

Take it the dealer....although you may need to leave it due to the random problem.

Suggest, maybe a trans. fluid pump if you have an automatic (a guess only).

 

I have a 2007 LS and mine does the same thing. I did not notice it until it got cold outside late last Fall. Now that the weather is warming up, it occurs less frequently and goes away sooner. Sounds like a bearing in either the alternator or a/c compressor. I hope whatever it is breaks before the warranty expires!

Hey Broadzilla - are you a T-Rex or a Velociraptor?

 

Could be the engine? (just kidding) Not sure this is the same but I have noticed a whirring sound when I shut the car off (with the radio off) and the sound only goes away when I open the door, so it’s on the same circuit as the radio shut off. (CD drive / stereo cooling fan?)

 

Well, since I'm really short and really mean and nasty, I must be a Valociraptor. At least that's what my kids say..

 

I had a 06 cobalt ss with the 2.4 and my 07 hhr has the 2.4 and they both make the same growning noise when cold. It gos away when coolent temp gets to 100 im not worryed about it.

 

Mine does it too. Car still runs fine so I don't worry about it.

 

Ours makes a whining noise too for the first few minutes. It's not that bothersome and it's gone in a mile or so of driving. If that's the worst problem we have I'll be happy! And we've been happy for over 2 1/2 years with our HHR now!

 

Wouldn't be the power steering pump because it doesn't have one. This car and most now use electric assist which is completely different from the old belt driven pumps with steering fluid.

 

Wow, another one brought up from the dead files !!
