will a faulty radiator cap cause overheating in this car?

Yes, Each vehicle has a certain PSI radiator cap and once it looses its pressure holding capability it could overheat as coolant and water has a higher boiling point when its under pressure. Have a shop pressure test your cooling system http://repairpal.com/lexus-repair-in-hollywood-florida
