I have recently noticed an intermittent squeaking noise coming from the front end. It happens at low speed turns (5 mph), after going over speed bumps and at 20-30 mph driving. It usually happens first thing in the morning or when the car sits for a while like when i'm at work. I'm taking it in to the dealer in two weeks but with my luck, it probably won't happen when they check it. Has anyone experienced this or know if there is a TSB? I have a 2010 IS 250 RWD.
