Scotty:
I own a 2018 Subaru crosstrek with 80k miles. There is a metallic flappy tinny sound — like the sound of a rattle snake tail. This sound only occurs when my car is in drive and held at between 2000-3500 RPMs. It also continues to make the noise, when I take my foot off the gas. I’ve already taken it to the Subaru dealership twice and spent over $300 and nothing was fixed. They told me the catalytic converter heat shield was re-seated but the sound remains. 😔 What is actually going on with this Subaru?! What can I do to troubleshoot this on my own? Thanks!

Without more localization it will be hard to tell you. Could be anything from exhaust to speaker wires to wheel bearings. Is it front, back, left, right, low, high?
