I could not tell where mine was coming from, like I said earlier it sounds like its coming from the passenger seat somewhere, it only happens the first time I try and start the car in the morning. I really think its nothing and was not going to look into it.

However, I guess I am now I parked it on the lift and tomorrow I will be under it when my wife fires it up, lets see if I can identify it.

 

i believe it's an 07 thing. weird how only yourself and i have an 07 on this entire forum~! chime in people... i don't want to wasting my time going to the dealership.

 

I have this "starting clunk" on my 04.

 

off to the dealership... i've read AC compressor starting noise and exhaust backfire. b back later

 

Fuel pump maybe?

 

my 03 had a slight clunk at start up, and so does my 06. its the whole engine/tranny/diff/driveline shaking once you hit the start button.

 

let us know what they say

 

cannot duplicate... & 7 miles were put on my car when all i told them was "clunks when starts" i think it was beat on today LoL.

 

it's probably exhaust pipe hanger hitting a frame, when starting an engine.

 

I could not hear it from under the car when my wife started the car today, she said she heard it but I did not, sorry....also it all looked good under there, plenty of clearance for everything.

I have not even tried to the AC yet, maybe I should just to see if it works or is noisy.
