Not yet fixed. Will schedule repair because noise is loud and irritating while sitting still in traffic. It's a metal on metal vibration sound.
the heat shield became loose and was very noisy. Ended up removing the shield. It isn't really necessary just more garbage that they put on so you can go get an expensive repair from the dealer.
