Squeal/whine sound from rear @ 3500RPM

Recommended Posts

On my 2006 C2S I notice when going up through the rev's (fast or slow) there is a high pitched squeal or whine from the rear of the car above 3500 RPM. It occurs whether I stay on the throttle or lift off as long as the rev's are around that 3500 range.

Just curious if anyone has experienced this as well or perhaps have some thoughts. My car has 14k miles and has always been meticulously maintained.

YES! I've noticed the squeal since last fall. I hear it most clearly when I am driving with the windows down, next to something that reflects sound, i.e. a wall, a jersey barrier, etc. It goes up and down with engine speed mostly with throttle on and lifting the throttle. It is driving me nuts! I took it to the dealer and got a tech to ride with me, but he couldn't hear it.

Not sure what to do. Feel like I'm slightly crazy, but I'm not.

Sounds like the same thing to me. If I had to pick I'd say it's from the right rear. You're right though, you hear it most when letting off the throttle or shifting gears in that 3500 range.

How can the tech at the dealer not hear it!?

Hi I had the same squeal on my 2006 C2S and it turned out after investigation to be a exhaust bracket that was the cause of the noise. The dealer replaced one side of the exhaust back box under warranty and the noise has now gone ( PSE exhaust).

I have a similar issue, whining noise between 4000 and 4200 rpm.

After checking different issues (belts, fans) the dealer says it's the left muffler. I would have liked it better if it was only a bracket...

I have not replaced it yet. I am waiting to see if it gets worse.
