Crackling / popcorn sound when I park.

The car is making popcorn. Why do you have to always be so critical???

I have 2007 dodge charger rt with the same problem I turn the car off and hear popcorn like sound from the left rear end of the car and feels like it wants to shut off. I had the boiling sound before and it was the car exhaust(hole in the rear end pipe water coming out) . My girlfriend has 350z and its a really nice car. The popcorn noise you describe only at stop signs, after the car shut off & low speeds 4 mph or less ?

You're probably just hearing your headlight fluid cooling down, especially if you are running your drl's and your headlights at the same time. Lots of heat to dissipate.

What the heck? Am I missing something? You turn the car off...OK. Then the car feels like it wants to shut off?

How can the car feel like it wants to shut off if it's already of?

Probably because it's a Dodge

I would look underneath the car to see if there is a red light or green light,if the green light is on your good but if the red light is on whatever you do don't turn the car on or BOOM

My guess: bubbling coolant in the block. The pump is now off when the engine stops, so the fluid is sitting in a multiple-hundred (300-400) degree oven.

Chargers don't use coolant. You plug'em in and they work.

He may be missing his piston return spring. I honestly wouldn't trust the Internet diagnosis and ask you local Nissan dealer to check for it. I heard there were a few 2009's that didn't get one. It's not a huge deal, just get it checked

Yeah it's probably the catalytic converter. However, you might want to do a visual inspection and make sure you didn't get something plastic stuck to any part of your exhaust system. I once ran over a small piece of construction grade plastic sheet in my 350Z and it caught onto my catalytic converter and made all kinds of weird noises and smells. I had to go through all kinds of stupid gyrations before I got it all off and the smell went away.
