Just curious.
Greetings. I've had my 08 LS460 just under 3 months. Love it. I've only put roughly 1100 miles on the car since I got it and 170 of that was the ride home from the dealership.
Now that it's colder, I'm noticing something and wanted to see if it was normal. My car is garaged. When I start it up and press on the gas, I get this high pitched whining sound. This goes on for maybe 5 or so minutes before it seems to go away.
Is this something due to the cold weather?
Thanks, Ron

Can be a dry bearing. Open the hood and see if you can find where the noise is coming from.
Inspect the belt as well to see of there are any obvious problems.
These motors are not as smooth or quiet as Ls 400 or ls430 motors. Direct injection is also a noise contributor.

Hi. No I don't use the Aux input much. The sound only occurs when i first start the car on a cold morning. When I gun the engine there is a whiny sound that clears up within 5 or so minutes.

Is there any way for you to capture a video recording the sound?

1. Serpentine belt
2. Idle pulley bearings
3. Belt tensioner.
I place my bets on the tensioner allowing the belt to slip when it's cold. This is usually a telltale sign of a tensioner on it's way out. Belt tensioners can fail unpredictably on all cars, any car and that is just the nature of the part.
Depending on the age of the belt I would replace if you are going to change the tensioner.

I know the idler pulley was a recall on my 2007. Perhaps you should check if your car was recalled, and if so was the pulley replaced.

Update: Today before driving the car (1st time in 2 days), I started it in the garage and let it warm for several minutes. No noise when pressing the accelerator to drive off.

You can check here to see if your car was part of the recall -
