We just recently purchased this car. The headlights are more like spot lights instead of flood. At night, the low beam bulbs direct a light down low, and there's a horizon above them, which is dark. It's a horizontal line ahead of you. When you start down a hill, towards the bottom, the dark area completely covers the road ahead. You cannot see anything in front and above you, like the road climbing in front of you. Also, that horizontal dark line moves up and down with the bumps in the road, and almost brings on motion sickness. If we get in a hilly area, that could become possible. The dealer won't adjust the lights higher, because they're in spec, now. This is dangerous, and should be addressed.
On the headlights the up and down arrows embossed into the plastic housing are backwards. This has caused me numerous tries at adjustment and has internally put the projector assembly out of alignment. This is the way the car came from the factory. Both sides are reversed.
