In the past month or so have had several occasions on start up and first 20 minutes of driving where I get a very high pitched whine almost like a dog whistle from the driver cockpit area. It is definitely electrical and not mechanical, it sounds like a relay or circuit or something. The sound builds up in volume then peaks out and eventually breaks up and fades away.
So unfortunately not something I can demo to the dealer yet.
Any thoughts???

Funny, I occasionally have an annoying high pitched whine coming from the passenger seat but only at speeds in excess of 100 mph and only when my wife is seated there. Coincidence?

Might be the Oil Pump problem.

Do you have active/massage seats? I notice it on mine if the massage is turned on...

My car does the same thing. I think it has something to do with the computer and all the other electrical systems starting up. Mine isn't really that loud and lasts for 5-10 min max.
