I really can't think of any other way to describe this.

I just got my new 06 Lux, there is a noise that sounds like a small cars horn, happens under normal acceleration and varies in length. It can also do it randomly under braking, but almost always when accelerating.

I am going to take it to the dealership, but I was hoping that someone might know what this is, so I don't have to wait for them to track down the problem.

I have searched the forums using just about any combo of words I could think of, please help.

Well, you do live smack in the largest Canadian Goose flyway, next time take a quick look above your rig....can never trust those dern Canadians!!!

I tried with the stereo on or off and it didnt make a difference.

It seems as if the sound only comes on when I depress the pedal a certain amount. If I leave the pedal depressed at the point when the sounds starts, I can keep it going. However, if I let up or press a little more it goes away.

The noise is your rear control arms. the bushings were redesigned for 2006 and make the noise. Gm has redesigned them(again) and the new ones are much better(quieter)

Is there a service bulletin or anything that I can show the dealership?

You may be having some rubbing on the sway bar.

I now know the sound you're typing about.

No bulletins at this time. have the dealer listen to the rear lower control arm bushings when doing a hard launch. What dealer did you take it to originally?

I've had the same sound, usually when I am accelerating in a turn, and mine is an '05. It's not the DVD in the headrest either because mine doesn't have that.

I've refrained from taking mine to the dealership with this problem knowing that I would really get the infamous service department comment, "Dumb woman...blonde one at that!":o
