The squealing noise when starting your 1999 Lexus RX300 could be due to a few potential issues. Most commonly, it indicates a worn or loose serpentine belt that may slip when the engine first starts. It could also be caused by a faulty tensioner or a problem with one of the accessories driven by the belt, such as the alternator or Power Steering pump. It's advisable to have it inspected to prevent further damage.
