Hi Scotty/everyone:
I have a 2017 Chevrolet Cruze 1.4 turbo and just surpassed 86,000km (roughly 53,400 miles). No major problems aside from noticing a loud sound seeming to come underneath the driver. When starting the car with a cool engine or when revving it, you can hear the vibration/noise. You can also hear it very little when accelerating on the first couple of gears. The transmission itself shifts smoothly and the engine runs great. My guess is something w/ the exhaust system (catalytic converter) or simply just a loose shield but not to sure what exactly. The exhaust pipe in the back seems to be stable. There is a video link below if it helps more:

Thank you (lmk if also the video link doesn’t work) 😊
