Hi. I own a 2005 STS V8. Lately, I have heard a little whir or whine while going around some curves. Any ideas? Thanks!

Took it to the dealer today. Turns out something's wrong with the power steerin. I Think they said the fluid is leaking. Took it to the dealer: for two other reasons: 1. when i receive a call on bluetooth, they can hear me, but i can't hear them. only on receiving calls though, if i call them, everthing is fine. 2. the brake pedal makes a squeak.

Smoey847: If your "whir on turning" is at low speed... and your power streering is OK... I had same problem that sounded like the steering shaft was binding (only at low speed)... Dealer scratched his head a couple of days, then found a problem in rack & pinion (steering mechanism)... Dealer replaced rack &/or pinion (warranty of course) and problem was cleared...

That is the only problem (with Blk/Blk, '06 V8 STS4) since bought new in Nov '05... Great car... Only competition was BMW 650, but with no rear leg room, $15k additional and only 2WD for the Bimmer... the STS was my choice.

I have same problem now, but only after a fix to another problem...and who knows, maybe its only coincidence? I had a clear fluid leak from rear portion of car...they told me it was a pinion seal and that a lot of these were having the same issue- after a couple of trys they got the car to stop leaking but now makes that sound and is a lot worse when I am trungin while backing up (kinda fast). I got used to it and no more fluid on the garage floor!


BTW I didn't think a pinion seal would be a big deal, but the dealer told me the job was over $700 if I wasn't under warranty.

Dealer finally got the part in. Taking it in tomorrow. Not really sure what the actual part is, but it's leaking fluid. That's all I really know. They had filled it with fluid last visit, haven't heard it since... Go figure...
