While driving at night on a highway, (70 MPH), and on Auto High Beam. The "Auto High Beam" function works without any issue. But if i give a left lane change signal, the entire headlight unit turns off (both right and left), and the navigation screen display changes to "day" setting (with bright blue back ground, rather than dark gray background); this is very spooky, imagine the road outside going pitch back and you getting blinded by bright light inside the cabin from the navigation screen.

This happens for 2-4 seconds max and then everything goes back to normal. And, this happens at random, and only with left turn signal. No issues with right turn signal.

The dealer's replies were as expected: "We cannot detect any issues using our diagnostic tools", "We cannot fix a problem that we cannot reproduce", "Are you turning lights off instead of hitting the turn signal?"

Any thoughts?

Thanks for your time
