After I turn the car off after driving anyhwere it makes a Click sound underneath every 3 seconds for about 10 minutes..like a cooling off period. And I hear a liquid sound kind of like water moving around a tank. Should I be worried about this? I have 250 miles on it as of today.

 

It is just the exhaust heat shield cooling down. All newer cars do this.
Several new owners have commented on it here in the past.

The liquid sound is either the AC condenser, or the coolant overflow tank changing levels. Nothing to worry about...

 

I HEARD THE SAME THING WHEN I BOUGHT MINE. BUT FOUND OUT IT WAS JUST THE ICE MELTING IN MY BEER COOLER! :twothumbs

 

Here is an old thread that covered this........

Like other's have said the clicking noise is exhaust system related, no worries there.

The liquid sound is the fuel sloshing around in the fuel tank, not sure if it's because of lack of baffels or there needs to be more ( if there's any at all ) sound deatener in that area. Again, no problem....just annoying.

 

Figured I'd hijack this thread rather than the original...

I've noticed in the mornings when I step out of the car to smoke after the car is off that near the back hatch area after a few moments comes a mechanical clicking noise usually in a pattern of three short clicks. Never really bothered me but curious as to what it might be.

 

I noticed that issue stoped after the 2nd or 3rd oil change. I just realized I have not heard that sound in awhile. Plus I have 14,300 miles so far
