There is a woman in the building that has a sports car and every time she starts up this car, it sounds like a loud screeching sound like a serpentine belt or some kind of belt issue. This has been going on for months now.

Sometimes she even starts the car up at 5 o'clock in the morning so it wakes us up sometimes. It's not every day but often and has been going on for months. I want to leave a note or report it somehow but I am not sure what my action should be.
