Had a crazy cold start rattle but no other issues when I first bought my 2018. They replaced the bushings and it was still a small rattle for a while but acceptable. Winter came and it started going nuts again on cold start (my car is garaged but passive heating, usually above 50*). One day it started a horrible noise 1700-1800 rpm's which was driving me nuts. Took it in to have it checked out and the tech put his hand over the valve solenoid on the top of the tips on the passenger side during startup and it stopped. They replaced my whole exhaust under warranty, problems gone. Said if it comes back they'll replace it again.

Nice to be taken care of, and clear they aren't willing to accept the rattle just like I'm not.
