LED Intelligent System
I've been very disappointed with the headlights of my 2018 2.0T Limited. Here are the two problems with the LED "Dynamic Bending Light" headlights. (LED Intelligent System).
1. Biggest problem is that there is no Cornering Lights to light up those dark UNLIGHTED street corners, driveways, or when entering some expressways from a DARK feeder road. I've had cars with and without Cornering lamps and never had this problem. The problem could be caused by either the LED bulbs or more probably by the reflector.
2. Second problem is the amount of light put out by the LED bulb is not as good as the HID bulbs in my 2015 Sport 2.0T Limited. Also, the 2018's "Dynamic Bending Light " does not "bend" or if it does, it bends very little. (I've had other cars with this feature, that all worked correctly). Also, the LED Bulbs projection has a Black (unlighted) spot in the "cutoff" area. (I found that the black spot is common when I checked out bulbs for sale). Don't like the "Color Temperature" of the LED. Color Temp is much better with the HID. Also the "cutoff" is so sharp, that you can't see road signs on the side of road, or unlighted overhead signs. (FWIW, I liked Quarts QI/QH best - like H4 bulbs).
My favorite Hyundai Technician has checked the Hyundai Service Line and there is nothing in there to correct these problems on my 2018.
The HID's of the 2015, (bulb D3S 35w) although not perfect, are better than the LED's of the 2018.
Don't like driving the 2018 at night. Normally take the 2015 when dark.
I think it's time to report the DANGEROUS Sonata LED Intelligent System of the 2018 to the NHTSA.
