Auto rain sensing wipers would not work. Lexus dealer declared problem as a warranty item and stated on his invoice:
"Found brackets for rain sensor permanently affixed to windshield not adhering, poor fit causing concern. Sublet to Glass company (Safelite) for windshield installation."
Took my 2012 RX 350 in at 7:30 am August 1 as scheduled by Lexus dealer, given a 2014 RX 350 "loaner" and was called at 2:20 pm reporting new windshield had been installed and I could pick up my vehicle. Well, it is a rainy day here so I got to immediately check it out. Works as it is supposed to.
