On several occasions, while driving at night, the Auto dimming headlights would not dim. Last evening, on 2 different occasions , on a rural road, no road signs, mailboxs . nothing that would cause a issues, the headlights would not go from high beam to regular (or Low beam.) 2 different times , vehicles coming at us, the lights would not dim. Time was apx 9pm , not a cloud in the sky. I had all so noticed while driving on a interstate , the same thing would happen, the lights would not dim,, drive maybe 50′ or 5-10 seconds later. they would dim. There seems to be no rime or reason of if or when they will dim. We had 18 and 22 Outback and they worked perfectly , where the Ridgeline has malfunctions. Asking the dealer they have not heard of anything wrong .. I have not had them to check , but have heard from other owners of the Ridgeline and they are complaining about the same thing. Uptill either the 22’s or 23 models the auto dimming worked perfectly .. Then Honda changed either the location of the sensor or changed the software.
