I have same faint metallic clicking noise....almost like tack in rear tire...have to have window open and radio off. Awaiting service bulletin ...sounds like we all have a common problem.

 

yup, I don't have jdman's noise; I have the faint clicking sound each time in 1st gear and even into second and third. but you really gotta be listening hard for it.

thanks to tabz for the description. I'm going into dealer in mission viejo, calif. on tuesday, 8/12. service guy already said he's never heard of this one---not a good sign. but I'll bring along the description and thanks also to yorkville!

will post results.

Ok, I've scoured the owner's manual, and found **TWO** places where it mentions this "clunk" noise upon first driving out (and listening to the noise this morning carefully, it actually sounds like "*CLICK*CLUNK* WooooOOOOOOUUUUM".

In the Owner's Manual, Starting and driving [5-21] regarding the Anti-Lock Brake System (ABS) Self-Test Feature: "The anti-lock brake system consists of electronic sensors, electric pumps, and hydraulic solenoids controlled by a computer. The computer has a built-in diagnostic feature that tests the system each time you start the engine and move the vehicle at a low speed in forward or reverse. When the self-test occurs, you may hear a clunk noise and/or feel a pulsation in the brake pedal. This is normal and is not an indication of any malfunction..."

In the Owner's Manual, Starting and driving [5-22] regarding the Vehicle Dynamics Control (VDC) System: "The computer has a built in diagnostic feature that tests the system each time you start the engine ... When the self-test occurs, you may hear a clunk noise and/or feel a pulsation in the brake pedal. This is normal and is not an indication of malfunction."

This must be what my service guy was talking about. And note that this ONLY occurs once (if at all) during an engine run (start/stop cycle). It does not/should not occur multiple times after the engine has already been started, and should not occur every time you accelerate.

Don't think I have a "clunk" here.
You know, I thought it was like the sound of a diverter flap swinging open in my muffler.....early in rpm cycle and very faint and metalllic.

tmoney - yes, that probably is the noise that you and I are experiencing. I have had other cars that have floating brake calipers and they reposition when the car first moves and make a clunk clunk. However, from what you posted it seems that what we are hearing is from the ABS testing. I just wouldn't call it a mechanical clunk, it seems more like an electronic buzz to me. But I have felt it in the brake pedal, so I am sure you have solved it! It is always surprising when a new car does something that no other car you have had did!!.
