Problems, problems and guess what? more problems!
Last time I was at the dealer, they told me that they did not hear anything unusual. Tell me if you hear something strange in this video,
(sorry, the 1st video is too short, I pressed stop by accident)
this noise lasts for about 1 - 2 minutes, on cold start. Basically every morning....
Here is another noise I'm getting lately. This is the automatic parking brake.
Is this normal, or am I being paranoid ?

The cold start sounds like it may be an idler tensioner starting to squeal a little. Parking brake sounds normal I guess but have never listened to it outside the car. When I bought my used GS the service history showed the EM brake motor was replaced. I took it off auto mode and only do it manually now just to hopefully save the motor a little longer.
You may be right, I might just need some lube. I'm in NY, the weather here is all over the place. The car has 36K miles.

It sounds like a noise some older cars make when it is damp/rainy outside.

My parking brake does not make that noise. I'm guessing it just needs something simple, like adjusting or lubrication.
Since the cold start noise only lasts a short time and only during a cold start it may be coming from something like a pump that is used for a short period of time at cold start to send warm/hot exhaust air back to the engine to help reduce the amount of time the engine must operate in a rich air/fuel mixture. If so, maybe the pump needs to be replaced or the bearing needs to be lubricated or replaced.

My parking brake doesn't make any noise. Sometimes when I get out it creaks once but nothing major.
My car doesn't make any noise upon start up, ever. It does sometimes idle down like it wanted to die though.

My parking brake on the GS never made any noise, and it doesn't on the LS either...
Definitely sounds like a bad tensioner pulley.
