It would seem that a quality-oriented, luxury manufacturer like Lexus would be very interested in the '06 RX 330 and '06 RX 400h windshield optical distortion – and want to take steps to correct it. Yet Lexus does not offer an email address on their website that we can find to report it – only phone contacts.
It would be great if anyone who notices what we have and finds it objectionable (in a $50k vehicle, in our minds, the windshield view should be pristine and 100% undistorted), nicely contact Lexus Customer Assistance by phone to report the issue so that it can be examined and rectified by the manufacturer. Multiple reports probably are one of the most expeditious ways that they will be made aware and the issue ultimately resolved.
