Anyone hear sounds sometime scary loud but not too loud while supercharging m3 ???
If you're talking about a bang coming from underneath the car while supercharging in the cold, yes. It's a known issue apparently. Flexing of metal as it gets hot. Nothing that causes problems.
You mean it's not the Elon under the Model 3 crawling out to eat your brains?
I thought that was why they where rolling out sentry mode.
Known issue. Thermal expansion. Seems to become less of an issue over time. Most noticeable during cold days.
