Auto bright head light system deactivates/reactivates indiscriminately, most frequently a few minutes after departing in the morning (still dark). Lack of proper bright light control while driving at night greatly reduces visibility making this a safety issue. I have provided video evidence to Lexus dealer demonstrating the problem who consulted with corporate Lexus; Lexus claims that they found my vehicle to be within Lexus specifications and has refused to further investigate nor repair. Information posted on the internet by numerous Lexus rx-350 owners reported the same problem - one suggesting that proper cleaning of the camera lens fixed the problem; I provided the evidence to Lexus and Lexus refused to attempt this solution. Following is Lexus guest experience center response; dear mr.: thank you for contacting the Lexus guest experience center. The entire Lexus organization is dedicated to providing Lexus customers with superior service. In circumstances that require our attention, we are interested in assisting in the resolution process.
