It may be some type of a relay or something located in the rear of the car due to the battery location in the trunk. I have no idea, just a guess.

It seem we have more and more threads that comes out after some people are not able to use the search button. No offense to anyone. If I was a moderator, I would delete them.

THANKS JMC007 YOUR wayyy COOL.
and when a problem isnt resolved and there arent any SURE answers ... I a college graduate umm...was taught TO ASK QUESTIONS. and a search was done but how can it work when it doesnt result in any conclusive 100% data? none of the threads had any answers just speculation. and as i was saying? does any one else have these problems? The knocking sounds like a person hitting the rear window. its really odd. and the exhaust has a wicked loud click. any one else?
sorry to be so rude but, i thought this was a place to find help ? not tough nuts.

the exhaus ticklin will become a rattling, then it will sound super loud. At this point you will have to take it to your dealer to change your exhaust system. a lot of the 05s and 06s had this problem. along witht he sunroof button falling off.

The noise that occurs right after start up and right after tuning the car off is coming from the fuel tank or purge canaster located right by the rear axle.

Have some one turn your car on while you are sticking your head under the rear of your car. You can hear it very clearly this way.

Hey dude I have already posted a true and definitive answer to that : The knock is normal and is caused by a kind of EVAP device located in the outside bottom of the gas tank. Mine does the same noise.
