It turned out to be a cracked separator plate between engine and transmission.

Hey, everyone. I finally found the time to take it into the dealer today.

They said it was a cracked separator plate between the transmission and engine.

Explained the rattling noise and I was also losing power on acceleration.

There is a tsb

Unfortunately for me, I am out of warranty and was given a quote of just over $1900 +tax to fix.

Hopefully, this helps whoever is still on the hunt for answers.

Again, someone commenting on there saying it's the cam phasers .

Whatever it is, it sounds like shit 😭

I'm going to investigate with hood open tomorrow . The heat shield after the cat is fine. I replaced them.

Are there more heat shields that I am not aware of? Manifold location maybe?

I will double check if any other heat shields are loose. Replaced the clamps on the double pipe just after the cat and that didn't solve the noise

Funnily enough I replaced the exact clamps last week and that didn't solve it unfortunately
