Sometimes, when I am sitting at a light, I hear this series of 'pops' coming from the right rear. It is about 5 pops and always sounds the same. I am assuming it is normal but what is it? It sounds almost as though someone is knocking on my window....popPOPpopPOPpop
Also, sometimes (fairly rare) when I am letting out the clutch in first (low speed accel.), the rearend makes a noise and the 'low traction' indicator flashes. I have not been able to duplicate on demand and it has done it since the car was new. It has done it in both first and reverse. I have close to 17k miles now
i don't know exactly, but if it sound like its inside the rear 1/4 panel the coil springs could be out of it boot and beyond my expetise to fix. Maybe some dealer could help. Im still look for someone decient, even to get an oil change
WOW...I thought I was crazy. My car has 19,000 miles on it and I've heard that "tap tap tap"......sounds like someone is gently knocking on the rear passenger quarter panel. It used to happen only when I put the car in reverse and I would hear the series of taps/pops just once. Now I occassionally hear them when waiting at a red light. I haven't a clue as to what it is.

I think it may be somthing to do with gas tank vent system???
For me, it happens when torque is applied to the drivetrain. Happens more at low speed, and also sometimes during shifts. I had mine in the shop and they determined it was the crossmember bushing that was making the pooping noise. This is the bushing they unbolt and drop to install the upper insulator bushing for the "thunk-in-the-trunk" TSB.
I think it is a little funny I read this thread before I went to work and when I got out I had the same experience that holden had. I was sitting at a red light and then I heard the tapping from the rear passenger area. I don't know if it matters, but I have an 06 model. What year do you guys have?
Thunk in the Trunk is when you accelerate "aggressively". As you shift, the crossmember get pushed up and thunks into the body. The TSB installs insulator bushings between the crossmember and the body.
That's not true, It's not a launch thing only, cause I get it when I go out and just start the car, a min or two later, knock, knock, knock, and thats before I even put it in gear.
