some times when i turn the car on i hear an annoying thump while the ignition is firing up the engine.. any feedback on this? thanks

Dealer told me it was "normal".

03.5 Sedan/B.Sil/Prem/Wntr/Aero/Tint/Rims/Hotchkis Sways--WHRER ARE OUR PARTS!
69 Chevelle Hard Top BB/4.11's/Posi

i've noticed that too, I imagine it is a normal sound.


Brilliant Silver/Graphite/Chrome Wheels '04 Sedan/5AT

i am "glad" to know my car is not the only one that makes that noise ! i hope it's normal...

I think it's the exhaust striking the floorpan.

Mine started around 4 months ago - 12k mi.

Hope nothing cracks later (after the warranty).
