The visor on the driver side of the car fails to stay upright limiting visibility. The headlights are so poor that it's almost impossible to see when driving on a dark road at night. It's to the point where I don't drive the vehicle at night because the road leading out provides little to no light and I would constantly have to ride with the bright on to be able to see including the fog lights. Both are safety concerns that could possibly lead to an accident or someone being seriously hurt. I've seen several complaints but no further actions have been initiated.
The low beams are very dim. The fog lights light up the road better than the low beams. I replaced the lowbeam bulbs with sylvania silverstar ultra bulbs which are very bright in my other car, they still are very dim.
