Thank you for requesting me!

The loud rumble noise you heard is most likely due to the extremely cold temperature outside. While I am not there in front of your vehicle and I have not heard the noise, based on my experience, it could be one of a few different things. It could be something related to the belts or pullies, starter motor or even something else. If the noise is no longer present and the vehicle starts and drives good, I suspect this is not going to be a safety or reliability issue so you can still start and drive the vehicle.
