New 2017 MDX AWD w/Tech, everytime after driving and turning the car off, I can hear some random ticking or clicking sound from somewhere of the bottom area. It will last a couple of minutes then gone. Is it normal? If it is, where exactly is it from? Anyone else notice this noise?

It's the exhaust system and extremely common, just about every car does it. When metal gets hot it expands and when you shut the car off it starts to cool and because the system is made of numerous sections the joints make the noise (friction).
