I have a 2001* ES300 Lexus. When I start in the morning I have to back out of a space and make a 90 degree turn both back and forward. I hear a noise that is very subtle and sounds like a rubbing sound. My mechanic checked it but could not find any problem with the power steering. Any idea where to go from here.
Did you ask him to check out the power steering or diagnose the rubbing sound? Those are different instructions.
Has he checked the brakes? I’ve heard wear indicators act like that.
Does it have ABS brakes? You might be hearing the ABS system going thru a self check.
