Headlights are inadequate on high or low beams. It seems that the light is focused into two narrow beams in an effort to make up for the low lumen level of the led bulbs. These narrow beams don't light up enough of what is in front of you for night driving. I have to use my fog lamps to turn onto streets without street lights on the corner. The recirculating switch for the ventilation system will not even reduce the amount of outside air coming into the cabin, much less occlude it. Not good in 5 o:clock traffic or when your behind a diesel burner. The dealership acts like they are clueless and say everything is working as it should. After reading this form with so many headlight complaints, I asked if they had ever gotten any complaints like mine and they denied that they ever have; and they did it with a straight face!.
