Before I take my 2017 SE in for an inspection, wanted to ask if anyone can recognize this rattling sound. It only does this after about 5 to 10 minutes of driving, I do always let the engine warm up before heading off. Might be thinking its something to do with the exhaust since I have seen some posts and videos about something coming loose and rattling around in the exhaust. Second area I am thinking is the CVT trans but I kinda doubt it. I was actually test driving it today after fixing multiple other rattling noises like the airbox and undertray that came loose. Here is an unlisted video of the sound I captured on that test drive. Sound started about a month ago but keeps getting worse, so, not sure what it could be. Would love to see if any of you have any ideas or suggestions for this.
